What You'll Learn

Use a fan with a bowl of ice water
Fans are a great alternative to air conditioning as they are more energy-efficient and budget-friendly. They can also be used to create a simple, effective, and eco-friendly air cooling system.
To cool down your room and improve your sleep, place a fan next to your bed with a bowl of ice water in front of it. The ice will create cold air, and the fan will blow this towards you. The breeze will pick up the cold water from the ice's surface as it melts, creating a cooling mist. This will help lower your body temperature and make it easier for your body to absorb the coolness.
You can also place a damp towel over your sheets to give your body some cooling relief while you fall asleep. It is recommended to place a dry towel underneath the wet one to avoid soaking your mattress with water, which can damage the foam.
Additionally, you can take steps during the day to prevent your room from heating up excessively. Keep windows and shades closed during the day and open windows in the evening to promote cross-ventilation. Minimizing the use of heat-generating appliances and preparing lighter, no-cook meals can also help keep the space cool.
Drinking ice water throughout the day and before bed is another way to keep your body cool. Alcohol should be avoided as it can promote dehydration, making it harder for your body to regulate its temperature.

Sleep on the bottom floor
If you live in a two-story home or an upper-level apartment, the top story will be warmer than the bottom floor. This is because hot air rises. So, if you're looking to beat the heat, your best option is to sleep on the bottom floor of your home.
- Drink a significant amount of water before bed to try and prevent night sweats.
- Avoid alcohol before bedtime as it can cause dehydration, making it harder for your body to regulate its temperature.
- Take a cool shower before bed and keep your hair damp. The extra moisture on your skin and scalp will help you feel cooler.
- Use a fan and place it strategically on the bottom floor. Place a bowl of ice water in front of it to create a cooling mist as the ice melts.
- Use light-coloured bed linens made of lightweight, breathable materials like cotton or linen. These fabrics promote ventilation and airflow, helping you stay cool while you sleep.
- If you still feel warm, consider placing your sheets in the fridge or freezer for a few hours before bed to get that extra cooling effect.

Wear cotton pyjamas
Wearing the right pyjamas can make a big difference when it comes to sleeping cooler without AC. Opt for lightweight cotton pyjamas, which are breathable and promote ventilation and airflow. Cotton is a natural fibre that is light and allows for airflow, helping to keep you cool. In contrast, heavier natural fibres like flannel or wool will likely make you warmer.
Cotton pyjamas will help you fall asleep faster and, according to research, will help you reach the deepest, most restorative sleep stage better than bulkier fabrics. Linen pyjamas are another good option, as this fabric is also breathable and promotes airflow.
It is also important to consider the colour of your pyjamas. Light-coloured pyjamas are preferable as they reflect heat, whereas darker colours absorb heat, making you warmer.
To further enhance the cooling effect of your cotton pyjamas, try placing your pyjamas in the fridge or freezer for a few hours before bed so they're cool when you put them on.

Freeze sheets and pillowcases
One way to beat the heat and get a good night's sleep is to freeze your sheets and pillowcases. Place your sheets and pillowcases in the freezer a few hours before bedtime. This will help you achieve a cooler temperature when you go to sleep.
You can also buy cooling sheets and pillowcases. Bamboo sheets, for example, are soft and often feel like silk or satin sheets, but they also stay cool to the touch. Bamboo is a porous material, allowing more airflow. Other options include sheets made from Tencel lyocell, which has a smooth and cooling touch, and Slumber Cloud's patented Outlast fiber, which uses phase change material (PCM) gel to absorb heat.
If you don't want to invest in new sheets, you can try putting a damp towel on your bed and pointing a fan at it to cool you down. You can also try sleeping under a damp cotton sheet or dampening your pyjamas or socks in cold water and wearing them to bed (don't forget to sleep on a towel to absorb excess water).

Avoid heat-generating appliances
To sleep cooler without AC, it is important to avoid heat-generating appliances. These appliances can increase the temperature of your living space, making it harder to sleep comfortably. Here are some ways to avoid them:
Firstly, unplug any electronics that you don't need overnight. This includes computers, TVs, and gadgets, which can generate significant heat. By unplugging them, you can reduce the overall temperature of your sleeping area.
Additionally, minimize the use of heat-generating appliances during the day. For example, instead of using the stove or oven, opt for lighter, no-cook meals. This will help prevent your living space from heating up excessively, making it more challenging to cool down at night.
Another way to avoid heat-generating appliances is to utilize public spaces with air conditioning during the hottest parts of the day. By spending time in air-conditioned libraries, cafes, or shopping malls, you can reduce your exposure to heat and give your living space a chance to cool down.
If you must use heat-generating appliances, try to do so strategically. For instance, run your dryer or dishwasher at night when it's cooler, or use a timer to delay their operation until the cooler evening hours. This will help minimize their impact on the temperature of your home.
Lastly, be mindful of your sun exposure and try to stay out of the house during the hottest parts of the day. By reducing your time in direct sunlight, you can lower your body temperature and minimize the need for heat-generating appliances like showers or fans.
