Don't exercise right before bed -
Exercise is great, but it heats up your body. Make sure you stop exercising a few hours before you go to bed, to allow your body time to cool back down.
Stay hydrated -
It's also important that you drink plenty of water throughout the day, so that you stay hydrated. You may also want to keep a glass of water by your bedside.
Don't eat right before bed - Eating a large amount of food may cause you to feel hot, so try and avoid this in the two or three hours before bed.
Find a great spot -
It is important to find the optimum sleeping spot. Bear in mind that cool, dark spaces are your best bet for a good night’s sleep on a hot night.
Avoid heavy bedding -
It goes without saying that heavy sheets are a no-go in the summer. However, it is a good idea to avoid heavy bedding in general.
Don't get things wet -
That said, it’s important to avoid taking anything wet into the bed with you. This will only trap humidity in your room and cause further discomfort.
Damp cloth -
Keep a damp cloth by your bedside and use it to wipe your face and arms if you wake up hot during the night.
Flip the pillow -
This is a great trick because the other side of the pillow is always cooler since it has not absorbed your body heat throughout the night.
Air out your room -
An hour before bedtime, open the windows in your bedroom. This will allow the air to circulate around your room and cool it down.
Ice pack -
Placing an ice pack under your neck or on your forehead is a great way to keep cool. You can find ice packs and cool packs in most grocery stores.
