What You'll Learn

Use a fan with ice water
Fans are a great way to cool down a room without AC. They redistribute the existing air in a way that makes it feel more bearable. However, fans don't blow cold air by themselves. So, to make the most of your fan, try using it with ice water.
How to Use a Fan with Ice Water
First, place a clean fan on the floor or as low as possible. Then, put a large bucket of ice or a large, shallow roasting pan directly in front of the fan. As the ice melts, the fan will blow cold air into the room, creating a cooling effect. You can also use frozen water bottles instead of ice. If you don't have ice or frozen water bottles, a damp, cool cloth placed in front of or over the fan will also help lower the temperature.
Other Tips
- Point the fan towards your bed or sleeping spot.
- Make sure the fan is not too high or too low, as you want the cold air to blow directly from the ice to the room.
- Replenish the ice as it melts.
- Drink something cold to keep yourself cool, hydrated, and comfortable.
- Change the direction of the fan blades to spin counterclockwise during the hot months to help push cold air downward.
- Use linens to boost your chill by storing your sheets or t-shirts in the freezer for 30 to 60 minutes before using them.
- Keep your windows, doors, and blinds shut during the day to avoid the hot sun from beating into your house. Then, during the evening, open your windows to let the cool air in.

Wear lightweight cotton pyjamas
Wearing lightweight cotton pyjamas is a great way to stay cool while sleeping without air conditioning. Cotton is a breathable fabric that allows air to circulate and wicks away moisture from your body. This helps to prevent you from sweating all over your sheets. Cotton pyjamas can also provide some relief from the heat by offering a cooling sensation when you first put them on.
It is recommended to choose breathable bedding materials such as cotton or linen when sleeping without air conditioning. These materials help to keep you cool by allowing air to circulate and wicking away moisture. On the other hand, synthetic materials should be avoided as they trap heat. Opting for cooling sheets or pillows can also provide relief from the heat.
If you don't have air conditioning, there are several other strategies you can use to stay cool while sleeping. One method is to use fans strategically placed around your room. A fan helps move the air around the room and your body, offering a sense of relief and increasing the chance of sweat evaporating. Placing a fan next to your bedside with a bowl of ice water in front of it can create cold air for you to sleep in. Additionally, facing a window fan outwards can blow the hot air from your bedroom outside.
Another way to stay cool without air conditioning is to lower your body temperature. Drinking room temperature water is easier for your body to process than cold water, which your body needs to warm up to absorb. Pressing a cool water bottle to your inner elbows or neck can also help lower your body temperature. Taking a cool shower before bed and patting your skin dry instead of rubbing it can also help you feel cooler as you fall asleep.
Adjusting your sleep schedule can also help you sleep without air conditioning during hot weather. Try going to bed earlier or waking up later to avoid the hottest part of the day and maximize your chances of getting a good night's sleep.

Sleep under damp cotton sheets
One way to beat the heat and sleep without AC is to sleep under damp cotton sheets. This method can be effective as the moisture in the sheets helps to cool you down. However, it's important to be cautious as damp sheets can also increase the humidity in your room and prevent your body from perspiring properly, which can make you feel hotter in the long run.
To sleep under damp cotton sheets, start by taking a cool shower before bed to lower your body temperature. Then, dampen your cotton sheet – not too much, just enough to make it damp. You can also try this method with a washcloth or towel instead of a sheet. If you don't want to get your bed damp, simply lay the damp washcloth or towel on your bed and position a fan to blow on you. Remember to keep your windows open and consider creating a cross-breeze by opening windows in other rooms of your house or apartment.
If you don't want to sleep under damp sheets, opt for crisp, white cotton sheets instead, as darker colours absorb heat more quickly. Additionally, washing your sheets at cooler temperatures will help preserve them and keep them cooler. Avoid exercising or consuming alcohol or caffeine close to bedtime, as these can all contribute to making you feel hotter and interfering with your sleep.

Adjust your sleep schedule
Adjusting your sleep schedule is a great way to improve your sleep quality, especially in hot weather. It is important to be consistent with your sleep schedule and make gradual changes. Start by fixing a bedtime and a wake-up time and sticking to it. You can also try to adjust your sleep schedule to take advantage of cooler hours. If possible, try going to bed earlier or waking up later to avoid the hottest part of the day and maximize your chances of getting a good night's sleep.
Exercising regularly can also help improve your sleep quality. Aim for at least 30 minutes of moderate aerobic activity at least five times a week. However, avoid exercising too close to bedtime as it may overstimulate your body and make it difficult to fall asleep. Instead, exercise at least 1-2 hours before bedtime.
Another way to adjust your sleep schedule is by planning your exposure to light. When you are exposed to light, your brain stops producing melatonin, the sleep hormone. Exposure to light in the morning can help you wake up. Try opening the curtains or taking a walk to get some natural light. At night, dim the lights to signal to your brain that it's time to produce melatonin and prepare for sleep. Avoid bright screens from computers, smartphones, or televisions as the glow can stimulate your brain for several hours.
Creating a bedtime routine and practicing relaxation techniques can also help you adjust your sleep schedule. Make your bedroom comfortable and quiet, and keep distracting lights and noises to a minimum. If you're having trouble falling asleep, consider using white noise to mask any environmental noise.

Choose breathable bedding
When it comes to choosing breathable bedding, it's important to select materials that will allow for adequate airflow and temperature regulation. Here are some tips to help you choose the right bedding for a comfortable sleep:
Choose the Right Fabric
Natural fibres such as cotton and linen are excellent choices for breathable bedding. Cotton is widely available and offers a soft and smooth texture. Look for cotton percale sheets, which have a tighter weave that makes them cooler and more breathable than other types of cotton sheets. Linen, on the other hand, has a looser weave, which promotes air circulation. It is highly breathable and effective at trapping less heat. However, linen can be more expensive and may feel rougher to the touch than cotton.
Explore Innovative Options
Consider bedding designed with cooling properties, such as the Slumber Cloud Performance Sheet Set, which uses Outlast cooling technology to store and release heat, regulating your body temperature. Another option is to blend Tencel lyocell with Slumber Cloud's patented Outlast fibre, which includes phase change material (PCM) gel to absorb heat. These sheets are highly breathable and offer a soft and cool sleeping experience.
Moisture-Wicking Properties
If you tend to sweat during sleep, look for sheets with moisture-wicking capabilities. For example, the Bedsure sheets on Amazon are made with rayon, which effectively wicks away moisture. Additionally, the Rest Evercool sheets impressed testers with their moisture-wicking properties and ultra-smooth jersey knit material.
Lightweight and Airy
Opt for lightweight and airy sheets, such as the Mellanni Iconic Collection Microfiber Sheet Set. While this set is thinner and more breathable, some users found it less effective at wicking away sweat. Another lightweight option is sateen sheets, which have a three-over-one thread weave, giving them a soft and cool-to-the-touch feel.
Mattress Considerations
Don't forget to consider the breathability of your mattress. Foam mattresses, especially memory foam ones, tend to retain heat. Look for organic, breathable mattress options or explore devices like the Eight Sleep Pod 3 to help regulate the temperature around your mattress.
