How to Make Your Top Bunk Cool

Quick answer

A hot top bunk can be cooled with simple steps such as a clip-on fan on a nearby surface, breathable cotton or linen bedding, blackout curtains, a lower thermostat and good hydration, while still following bunk bed safety rules.

Clip a fan to a sturdy surface beside the bunk, not to the bunk itself.
Children younger than 6 should not sleep in the top bunk, and nothing should hang from it.
Confusion, slurred speech, passing out or a temperature above 103°F can mean heat stroke, so call 911.

You’ve scored the top bunk. Congratulations on ascending to the penthouse suite of sleeping arrangements.

But wait, why does it feel more like a sauna than a sanctuary up there? Heat rises, after all, and suddenly your lofty domain is less “room with a view” and more “roasting on high.” Don’t sweat it (literally). This guide covers ways to turn a hot top bunk into a cooler place to sleep.

Get ready for the coolest tips and tricks to chill out your top bunk.

Safety first. A top bunk has rules that some cooling tricks can break. According to Nationwide Children’s Hospital, children younger than 6 are too young to sleep in the top bunk, guardrails need to extend at least 5 inches above the mattress top including any added pads, and the top bunk should be kept away from ceiling fans. Do not hang, tie or clip cords, straps, scarves or fabric to the bunk.

To get you cool as fast as possible, let’s first talk about the top 10 best ways to make your top bunk cool.

Some of these are obvious, but they are the sensible place to start. After that come 90 more ideas.

1. Use a Clip-On Fan

A ceiling fan and a top bunk do not mix, so a small clip-on fan is the usual substitute. Clip it to a shelf, desk or other sturdy surface beside the bunk, not to the bunk itself, and aim it at the bed. Choose one with a full blade guard and adjustable speeds.

A fan cools people by moving air over skin. It does not lower the room temperature, and the CDC advises using fans only when indoor temperatures are below 90°F.

Koonie is one brand that sells rechargeable clip-on fans.

2. Invest in Cooling Bedding

Your bedding plays a significant role in how cool or warm you feel at night.

Ditch those heavy flannel sheets and opt for materials designed for breathability and temperature regulation.

Light cotton and linen sheets let more air through than flannel. Sheets sold as bamboo are usually rayon (viscose) made from bamboo, so treat cooling claims on the label as marketing.

A gel mattress topper or gel pillow can feel cooler at first. On a top bunk, check the thickness of the topper before buying: the guardrails must still stand at least 5 inches above the top of the mattress with the topper on.

California Design Den is one brand that sells cotton sheets.

3. Freeze Your Bedsheets

It might sound unconventional, but freezing your bedsheets is a game-changer.

Place your sheets and pillowcases in a sealed plastic bag and pop them into the freezer for a few hours before bedtime. When you’re ready to sleep, make your bed with the icy linens. The initial coolness provides a refreshing contrast to the warm air, helping you drift off more comfortably.

Sure, the chill won’t last all night, but it’s a blissful start.

4. Put a Bowl of Ice in Front of a Fan

No AC? A bowl of ice and a fan can take the edge off.

Fill a shallow pan or bowl with ice and set it on a stable table or dresser in front of a fan, never on the bunk. Air blowing across the ice feels cooler close to the fan for a short while. It is not an air conditioner and will not cool a whole room. Keep the bowl away from the cord and plug of the fan and any power strip, and empty it before it can spill.

5. Install Blackout Curtains

Sunlight streaming into your room all day can turn it into a heat trap, especially for the top bunk.

Blackout curtains are designed to block out sunlight and UV rays, which helps reduce heat gain through the window. By keeping your room shaded during peak sun hours, you ensure a cooler environment when it’s time to climb up to your bunk.

Plus, they help you sleep in on weekends by keeping the morning light at bay. Win-win!

Pick cordless curtains or blinds for a child’s room, and keep the bunk away from windows and window cords.

NICETOWN is one brand that sells blackout curtains.

6. Keep a Spray Bottle Nearby

Sometimes, the simplest solutions are the most effective.

Fill a spray bottle with cold water and keep it within arm’s reach of your bed. Whenever you start feeling too warm, give yourself a light misting.

The evaporation of the water from your skin has a natural cooling effect, similar to how sweating works (but less gross). For an added chill, store the spray bottle in the fridge during the day.

7. Adjust the Thermostat

If you’re fortunate enough to have control over your home’s thermostat, take advantage of it.

Lower the temperature a few degrees before bedtime to offset the heat that rises to your top bunk.

Be mindful of energy consumption and consider using programmable thermostats that adjust temperatures automatically. Of course, this might require some diplomatic negotiations with roommates or family members who prefer warmer temperatures. Time to perfect your persuasive skills.

8. Stay Hydrated

Keeping yourself cool isn’t just about external factors; internal temperature matters too.

Consistently hydrating yourself by sipping water throughout the day helps your body maintain a balanced temperature. Dehydration can make you feel hotter, so keep a water bottle handy. Bonus: climbing up and down to refill your water doubles as exercise, so you’re basically multitasking your way to better health.

9. Sleep in Lightweight Clothing

Your choice of sleepwear can make or break a comfortable night’s sleep.

Swap out heavy pajamas for ones made of lightweight, breathable fabrics like cotton or linen.

These materials allow air to circulate and moisture to evaporate, keeping you cooler. If you’re feeling particularly daring (and appropriate for your living situation), you might even consider sleeping in minimal clothing.

For children, the US Consumer Product Safety Commission says snug-fitting or flame-resistant sleepwear is the safest choice.

After all, less is more when it comes to beating the heat.

10. Use a Cooling Mattress Pad

A cooling mattress pad is an unsung hero in the quest for a cooler top bunk.

These pads are designed with materials that either absorb and dissipate heat or actively cool through technologies like gel-infused foam or phase-change materials. By regulating the temperature of your sleeping surface, they help prevent heat from building up beneath you.

Measure before buying for a top bunk. With the pad on, the guardrails still need to reach at least 5 inches above the sleeping surface.

It’s like giving your mattress a personality makeover, from hothead to chill companion.

The Other 90 Ways to Make Your Top Bunk Cool

Those are the main tactics. There is plenty more to try, from simple habits to bigger home fixes.

From DIY hacks to lifestyle tweaks, the following 90 tips will equip you with an arsenal of cooling strategies.

11. Skip the Bed Canopy

A fabric canopy looks nice, but it is a poor fit for a top bunk. Fabric draped around the bed blocks moving air, and anything hung from or over a bunk can entangle a child. IKEA recalled children’s bed canopies in 2014 because a young child could get entangled at the neck in the fabric.

Leave the space around the top bunk open.

12. Use a Chillow Pillow

The Chillow is a water-filled cooling pad that absorbs and releases body heat, according to its maker.

It needs no electricity or batteries.

It suits people who keep flipping the pillow in search of the cool side.

13. Apply Cooling Gel Packs

Place sealed gel packs in the freezer during the day and tuck them under your sheets at night.

Place them near your feet or behind your knees for about 20 minutes as you settle in, then set them aside. Just make sure they’re wrapped in a cloth to prevent direct skin contact and potential frostbite. Because nobody wants to explain gel pack-related injuries.

14. Turn Off Electronics

Electronics emit heat even when they’re not in active use.

TVs, gaming consoles, and even chargers can contribute to the room’s overall temperature. Before heading to bed, unplug unnecessary devices to reduce ambient heat. As a bonus, you’ll save on your electricity bill and perhaps rediscover the lost art of analog entertainment.

15. Use a Dehumidifier

Humidity can make the heat feel more oppressive by hindering your body’s ability to cool itself through sweating.

A dehumidifier removes moisture from the air, which can make a humid room feel less sticky. It also warms the air around it slightly as it runs, so it suits a room that is damp more than hot. It’s like turning your space from a sticky swamp into a dry desert oasis, minus the scorpions and cacti.

16. Sleep with Wet Hair

After your evening shower, skip the blow-dryer and head straight to bed with damp hair.

As the water evaporates, it cools your scalp. You’ll not only feel more comfortable but might also wake up with effortless, tousled waves. Or, you know, the bedhead of the century, but that’s a risk worth taking.

17. Position Fans Strategically

Fans are more effective when used thoughtfully.

Place a fan near an open window facing outward to push hot air outside, while another fan pulls cooler air in from a different window. This setup creates a cross-breeze that can significantly lower the room’s temperature.

It’s like orchestrating a symphony of wind, with you as the maestro of cool.

18. Hang a Wet Sheet Near an Open Window

Like the bowl of ice, hanging a damp sheet in front of an open window cools incoming air through evaporation.

As the breeze passes through the wet fabric, it picks up moisture and cools down, acting like a natural air conditioner.

This works best in dry air. In humid weather it adds moisture and can make the room feel muggy. Hang the sheet at the window, never from the bunk.

Just be prepared for curious looks from neighbors wondering why your laundry is airing out at night.

19. Use a Portable Air Conditioner

When fans and DIY solutions aren’t cutting it, a portable air conditioner can be a game-changer.

These units are designed to cool specific areas and can be moved as needed. While they require an investment and proper ventilation (usually through a window), the relief they provide on sweltering nights can be priceless.

It’s the nuclear option in the war against heat.

20. Freeze a Hot Water Bottle

Who says hot water bottles are just for warmth?

Check the instructions from the maker before freezing one. If freezing is allowed, leave room for the water to expand. Wrap the bottle in a cloth and place it at the foot of the bed. It’s like having an icy pet that doesn’t require feeding or walks.

21. Create Cross Ventilation

Maximize airflow by opening windows on opposite sides of the room or house.

This creates a natural wind tunnel that pushes hot air out and pulls cooler air in. If children use the room, fit window stops so the windows open no more than 4 inches, and keep the bunk bed away from the window. The CPSC warns never to depend on screens to keep children from falling out. It’s a simple yet effective way to leverage Mother Nature’s own cooling system.

Here is a video on how to cool your entire house (even the top of your bunk bed):

YouTube Video by CBC News — Ways to Make Your Top Bunk Cool

22. Use Light-Colored Bedding

Light colors reflect sunlight and dark colors absorb it, which matters for bedding that sits in direct sun during the day. At night, the weight and weave of the fabric matter more than the color.

Choose thin, breathable bedding first and a light color second.

23. Sleep Alone

Sharing a bed with a partner, a pet or a giant teddy bear means sharing body heat.

If overheating is a significant issue, consider sleeping solo during hot nights. It’s not a permanent breakup, just a temporary arrangement until cooler temperatures prevail. Absence makes the heart grow fonder, after all.

On a bunk bed this is also a safety rule: the warning label required on US bunk beds says only one person should use the upper bunk.

24. Remove Rugs or Carpeting

Floor coverings like rugs and carpets can trap heat and make a room feel warmer.

Bare hardwood or tile feels cooler underfoot. Do not expect it to change the air temperature much.

Plus, it’s an excuse to show off those floors you paid so much for (or discovered under the carpet you pulled up in a fit of heat-induced frustration).

25. Use the Right Mattress on the Bunk Base

Air moving under a mattress helps it shed heat, and most bunk beds already have a slatted base.

Do not raise, swap or rebuild the mattress support on a top bunk. Use the mattress size and maximum thickness given in the instructions for the bed, so the guardrails still stand at least 5 inches above the mattress.

26. Keep Your Door Open

An open door allows air to flow freely, reducing heat buildup in your room.

This is especially helpful if the rest of your home is cooler. Just be mindful of privacy and noise considerations. You don’t want to exchange one discomfort for another. Communication with housemates or family members can go a long way here.

There is a trade-off. Fire safety campaigns advise sleeping with the bedroom door closed, because a closed door holds back heat and smoke in a fire. Keeping the door open through the evening and closing it at bedtime is a reasonable compromise.

27. Utilize Ice Packs

Similar to gel packs, ice packs can be placed under your pillow or at the foot of your bed.

Wrap them in a thin cloth to prevent direct contact with your skin, avoiding frostbite or discomfort. They provide a localized cooling effect that can make a significant difference when trying to fall asleep.

28. Avoid Spicy Foods Before Bed

As delicious as that late-night curry might be, spicy foods can leave you flushed and sweating.

Opt for milder meals in the evening to keep your internal thermostat in check.

Your taste buds might protest, but your overheated body will thank you.

29. Unplug Unused Electronics

Even devices in standby mode can emit heat.

Go around your room and unplug chargers, lamps, and gadgets that aren’t in use. This not only reduces heat but also saves energy, a win for both you and the planet. The effect on room temperature is small, but it costs nothing.

30. Use Aloe Vera Gel

Aloe vera isn’t just for sunburns. Applying a thin layer of pure aloe vera gel to your skin can have a cooling effect. Store the gel in the refrigerator for an extra chill. It’s soothing, hydrating, and might make you smell like a spa, which is never a bad thing.

31. Sleep on a Bamboo Mat

A woven bamboo mat laid over the mattress gives a firm surface that does not hug the body the way foam does.

Check that the guardrails still stand 5 inches above the sleeping surface with the mat in place.

32. Get a Bedside Mini Fridge

A small fridge near the bed makes it easier to keep drinking water through a hot night. Put it on the floor or a sturdy table, never on the bunk, plug it straight into a wall outlet, and remember that a fridge gives off heat as it runs. Check the recall list before buying or using one. Curtis International recalled Frigidaire-brand minifridges because their electrical parts can short circuit and set the plastic housing on fire.

33. Wear a Cooling Headband

Cooling headbands are made with special fabrics that stay cold when wet.

Wear one to bed to keep your head cool, which can make a warm night more bearable. It’s like a sweatband but with a cooler purpose. Stylish? Maybe not. Worth a try.

34. Use a Mist Fan

Combining the power of airflow with the refreshing sensation of mist, misting fans disperse tiny water droplets into the air, cooling it as they evaporate.

They’re especially effective in dry climates where evaporation happens quickly.

Keep the mist away from bedding, outlets and power strips, and skip it in humid weather.

It’s like having your personal micro-shower without the risk of waterlogging your bed.

35. Install Window Film

Reflective window film can block a significant amount of solar heat from entering your room.

It’s a thin layer applied directly to the window glass and can reduce heat gain without obstructing your view. It’s like giving your windows a pair of sunglasses: stylish and functional.

36. Paint Your Room a Cool Color

Colors like blues and greens can psychologically make you feel cooler.

While the effect is subtle, every little bit helps when you’re battling the heat. Plus, it’s an opportunity to refresh your space and express your inner interior designer.

37. Check the Guardrails After Adding Bedding

Every pad, topper or mat raises the sleeping surface. Guardrails need to extend at least 5 inches above the mattress top, including any added pads. A hammock is not a safe substitute for a bunk mattress.

38. Run the Ceiling Fan, but Move the Bunk

With air conditioning, a ceiling fan lets you set the thermostat about 4°F higher with no loss of comfort, according to the Department of Energy. Keep the top bunk well away from the blades.

39. Shower Before Bed

A cool shower or bath is standard advice for cooling down in hot weather, and it rinses off sweat.

For falling asleep, research points to warm water: a University of Texas review found that a warm bath or shower 1 to 2 hours before bed helped people fall asleep about 10 minutes faster on average. Warm water draws blood toward the hands and feet, which helps the body shed heat afterward.

40. Place Plants Around the Room

Houseplants make a room feel calmer, but there is no good evidence that a few pots will cool a bedroom.

Enjoy them for the look, and keep pots off the bunk.

41. Keep Lights Off

Incandescent bulbs release about 90% of their energy as heat, while LEDs emit very little, according to the Department of Energy.

Turning off unnecessary lights reduces heat and saves energy. Consider using task lighting instead of overhead lights or switch to cooler, energy-efficient bulbs.

Embrace the ambiance of dim lighting. It’s romantic and practical.

42. Use a Feather Pillow

Some people find feather and down pillows less clammy than solid foam, though results vary from person to person.

If allergies are a concern, look for hypoallergenic options.

43. Install an Attic Fan

An attic or loft space can trap a lot of heat, which then radiates down into your living area.

Installing an attic fan helps expel hot air, reducing the overall temperature in your home. This is a job for the homeowner and an installer, and it only helps if the attic is sealed from the rooms below and its vents are clear.

44. Sleep in the Basement

If all else fails and you have access to a lower level, consider relocating your sleeping area temporarily or permanently.

Basements are naturally cooler because they’re below ground level. It’s not a glamorous option, but desperate times call for cooler measures.

Only sleep in a basement room that has a working smoke alarm and two ways out.

45. Block Heat Sources

Identify and mitigate sources of heat in your room.

This could include switching off or moving lamps, electronics or appliances that give off heat. Never cover a lamp or a device that is switched on. Even small changes can contribute to a cooler environment.

It’s like playing detective, but the only mystery is why you didn’t think of this sooner.

46. Use Cooling Eye Masks

A gel-filled cooling eye mask can provide relief and help you relax. Store it in the fridge during the day and wear it to bed. It soothes tired eyes and can help reduce puffiness, a beauty treatment and cooling strategy in one.

47. Try Breathable Mattress Protectors

Mattress protectors are essential for hygiene but can trap heat.

Opt for ones made from breathable materials like bamboo or cotton that wick away moisture and allow for better airflow. It’s a behind-the-scenes change that enhances your comfort.

48. Hang Reflective Window Shades

Reflective shades or blinds bounce sunlight away from your windows, reducing heat gain.

They’re especially effective for windows that get direct sunlight during the hottest parts of the day. Think of them as shields defending your cool sanctuary from the sun’s fiery onslaught.

49. Create a Bedside Ice Bucket

Fill a bucket with ice and place it near your bed.

The ice takes a little heat from the air right around it, though not enough to cool a room. Keep it on the floor or a table, away from cords and power strips. The ice can also go in cold drinks.

50. Practice Cooling Breathing Techniques

Some breathing exercises are meant to feel cooling, and slow breathing can be calming at bedtime.

One method involves inhaling slowly through your mouth as if sipping through a straw, then exhaling through your nose

It might sound odd, but it’s a technique used in yoga to cool the body.

51. Use a Silk Sleep Mask

Silk is a naturally cool fabric. Wearing a silk sleep mask not only blocks out light but also feels refreshing against your skin. It’s the kind of small luxury that can make bedtime feel a bit more special and cooler.

52. Install a Swamp Cooler

Also known as evaporative coolers, these devices cool air by passing it over water-soaked pads, causing the water to evaporate and cool the air. They’re most effective in dry climates and use less energy than traditional air conditioners.

They need a partly open window to work and are only suitable for areas with low humidity.

It’s like bringing a bit of the oasis into your room.

53. Sleep on the Floor (Temporarily)

Since heat rises, the floor is often the coolest part of the room. Set up a makeshift bed on the floor for particularly hot nights. It’s not a permanent solution, but when you’re desperate for relief, it’s a viable option.

54. Flip Your Pillow Frequently

Sometimes, the simplest actions can provide immediate relief. Flipping your pillow exposes the cooler side, giving you a brief respite from the heat. It’s a small comfort, but in the sweltering darkness, every bit helps.

55. Wear Moisture-Wicking Sleepwear

Athletic wear isn’t just for the gym.

Moisture-wicking fabrics draw sweat away from your skin, helping you stay dry and cool. Look for sleepwear made from materials like polyester blends specifically designed for this purpose.

56. Try a Buckwheat Pillow

Buckwheat hulls allow air to flow freely through the pillow, preventing heat buildup.

They also conform to your head and neck for support. It’s a different feel from traditional pillows but worth trying if overheating is a chronic issue.

57. Avoid Alcohol Before Bed

A nightcap might feel relaxing, but alcohol can disrupt sleep and works against staying hydrated. Choose water or a cool herbal tea.

58. Use Peppermint Oil with Care

Diluted peppermint oil gives a cooling sensation on the skin because of the menthol in it. It does not cool the room. Always dilute it first, and do not use it on or near the face of an infant or small child, because inhaling menthol may affect their breathing.

59. Set Up a Tent Fan

Originally designed for camping, tent fans are compact and battery-operated, perfect for use in tight spaces like the top bunk. Stand one on a nearby shelf or dresser for a direct breeze with no outlet needed. Do not hang it from the bunk or above the bed, and keep any strap or cord out of the bed.

60. Try Temperature-Regulating Bedding

Some bedding uses phase-change materials that absorb body heat as the sleeper warms up and release it as they cool down. Outlast is one maker.

61. Hang a Soaked Towel

Hang a damp towel in front of an open window, never from the bunk. Air passing through it is cooled a little by evaporation. This only helps in dry air. In humid weather it makes the room feel muggy.

62. Know When a Fan Stops Helping

The CDC says to use fans only when indoor temperatures are below 90°F. Above that, a fan can increase body temperature. Ready.gov adds that a fan should not be relied on as the primary cooling device.

63. Let Your Feet Breathe

The body sheds heat through the hands and feet. Keep feet uncovered or wear breathable socks to let heat escape.

64. Avoid Heavy Meals at Night

A large, heavy meal late in the evening can leave you warm and uncomfortable in bed. Lighter dinners are easier on a hot night.

65. Spend the Hottest Hours Somewhere Air-Conditioned

A mall or library works. Air conditioning is the most reliable protection in extreme heat.

66. Sleep Spread-Eagle

Maximize airflow around your body by sleeping with your limbs spread out. This reduces heat buildup where skin contacts skin. You might look like a starfish, but you’ll feel cooler.

67. Tie Up Long Hair

Keeping long hair off your neck and shoulders can make a big difference in how hot you feel. A loose bun or braid minimizes heat retention and keeps you from waking up in a sweaty tangle.

68. Enjoy a Slushie Before Bed

Cool down from the inside by enjoying a cold, icy beverage before sleep. Just be mindful of sugar and caffeine content that could disrupt your rest. A homemade fruit slushie is both refreshing and hydrating.

69. Avoid Caffeine

Caffeine late in the day makes it harder to fall asleep, and a hot night is hard enough already. Switch to decaffeinated drinks in the afternoon and evening.

70. Check That You Are Drinking Enough

Keep a water bottle within reach and drink through the day. Pale urine is a common sign of drinking enough.

71. Turn Fans Off in Empty Rooms

A fan cools people with moving air, not the room itself, so switch it off when nobody is there.

72. Use a Hydro-Cooling Mattress Pad

These systems use water in a pad on the mattress to carry heat away from the bed, and most let the sleeper choose a cooling level. For a top bunk, check where the control unit, hose and power cord will go before buying.

The Adamson B10 Bed Cooling System is one example.

73. Sleep Next to Frozen Water Bottles

Freeze water bottles and stand them in a bowl or tray on a table near the bed, not on the bunk. They will not cool the room, but there is cold water ready to drink as they thaw.

74. Check on Kids in the Top Bunk

Young children rely on adults to keep them cool and hydrated. Look in on a child in a top bunk on hot nights.

75. Use a Cooling Neck Towel

Cooling towels hold water and feel cool as it evaporates. Drape one around the neck while winding down, then take it off before sleep. They recharge with a soak in water.

76. Sleep Under a Damp Sheet

For the brave and slightly desperate, sleeping under a damp (not wet) sheet can provide evaporative cooling throughout the night. Be cautious of making your bed too damp, which can lead to discomfort or mildew over time.

77. Apply Menthol Lotion

Lotions containing menthol create a cooling sensation on the skin. Gently massage a small dab onto your pulse points, for example, your wrists and neck. Test on a small area first to ensure you don’t have a sensitivity.

Keep menthol products away from the faces of infants and small children.

78. Drink Cold Herbal Tea

Herbal teas like peppermint taste cool and refreshing. Brew it ahead of time and chill in the fridge for a refreshing pre-bedtime beverage that also hydrates.

79. Install Thermal Curtains

Thermal curtains are designed to insulate against heat transfer. In the summer, they keep heat out, and in the winter, they keep it in. They’re an investment that pays off year-round.

80. Use an Oscillating Fan

Oscillating fans circulate air more effectively than stationary ones by moving the airflow around the room. This helps distribute cool air more evenly and prevents hotspots.

81. Try a Bed Fan

Bed fans are designed to direct airflow under your sheets, cooling you directly. Some models can be controlled via remote, allowing you to adjust settings without getting up. It’s a targeted approach to staying cool.

82. Freeze Your Pillowcase

Place your pillowcase in a plastic bag and freeze it for a short time before bed. Slip it back onto your pillow for a burst of coolness as you settle in. It’s a quick fix that requires minimal effort.

83. Use Separate Bedding

If you share a bed, using individual sheets and blankets can reduce shared body heat. It also allows each person to choose bedding that suits their temperature preferences.

84. Embrace Minimalism

Piles of stuff in front of vents, fans and windows block airflow. Clear those paths first. A tidy room can also be mentally refreshing.

85. Wear a Wet Bandana

Similar to cooling towels, a damp bandana worn around the neck or head can help lower your body temperature. It’s an old-school trick that’s simple yet effective.

Take it off before falling asleep. Nothing should be tied or wrapped around the neck of a child in bed.

86. Avoid Evening Workouts

Exercise raises your core body temperature, and it takes a while to come back down. If possible, schedule workouts for the morning or early afternoon to allow your body time to cool down before bed.

87. Stay Out of the Sun

Limit sun exposure during the day to prevent your body from overheating. Wear hats, use sunscreen, and seek shade when possible. Starting the evening cool makes it easier to stay that way.

88. Use a Solar-Powered Fan

Eco-friendly and cost-effective, solar-powered fans run without adding to your electricity bill. Place them near windows to enhance natural ventilation during the day.

89. Put a Night Light by the Ladder

Hot nights mean more trips down for water. A night light near the ladder makes each trip safer.

90. Skip the Bed Tent

Bed tents are sold for privacy and darkness, but an enclosed tent blocks the breeze from a fan. On a top bunk it also adds fabric, poles and straps where a child could become entangled. Leave the bunk open on hot nights.

91. Use Heat-Reflective Paint

Reflective roof coatings are a more permanent fix for hot top-floor rooms, because a roof that reflects more sunlight absorbs less heat. This is a job for a homeowner or landlord, and it applies to roofs, not indoor walls.

92. Avoid Using the Oven

Cooking with the oven can heat up your entire living space. Opt for no-cook meals or use smaller appliances like toaster ovens and microwaves to minimize heat output.

93. Point a Window Fan Outward

Window fans work best in windows facing away from the prevailing wind, pushing hot air out of the home, according to the Department of Energy.

94. Sleep in a Wet T-Shirt

Wearing a damp (not dripping wet) T-shirt to bed can provide evaporative cooling. Be mindful of moisture levels to avoid discomfort, and skip this in humid weather.

95. Use Phase-Change Materials

Some bedding products incorporate phase-change materials that absorb and release heat to maintain a stable temperature. It’s advanced science working quietly to keep you comfortable.

96. Install a Window AC Unit

If other methods aren’t sufficient, a window air conditioning unit can provide targeted cooling. Follow the instructions from the maker and make sure the unit is secure in the window.

97. Take a Cold Foot Bath

Before bed, soak your feet in cold water to cool off. It’s a relaxing ritual that can signal to your body that it’s time to wind down.

98. Try an Ice Pack Hat Before Bed

Hats with pockets for ice packs can cool the head for a short spell before bed. Make sure ice never touches bare skin, limit use to about 20 minutes, and take the hat off before falling asleep.

99. Install Floor Fans

Position fans at floor level to push cooler air upward. This combats the natural rise of warm air and can make the room feel more comfortable overall.

100. Know When Heat Is Dangerous

Being uncomfortable is one thing. Heat illness is another. The National Weather Service lists heavy sweating, weakness, dizziness, nausea, headache and muscle cramps among the signs of heat exhaustion: move to a cooler place, loosen clothing, apply cool, wet cloths and sip water. A throbbing headache, confusion, slurred speech, a body temperature above 103°F or passing out can mean heat stroke: call 911 right away. Check on kids in top bunks during a heat wave, and on the hottest nights sleep on a lower floor or somewhere air-conditioned.
