Rising temperatures and high humidity make it a lot harder to sleep. This is partly because it’s such an uncomfortable experience and partly because sleep itself is regulated by temperature. If you don’t have an AC, here are 6 easy ideas for surviving a heatwave.

1. Mist yourself.

The process of evaporation absorbs heat, bringing temperatures down. Spray yourself with a fine mist of water to hack this process: you can buy a face mist, borrow a plant mister, or find a spray bottle from the hardware store. Unfortunately, if you are somewhere with high humidity, evaporation won’t work, but read on for more tips.

2. Take a shower. A hot shower.

A hot or warm bath can counterintuitively help you cool down. This is because the hot water encourages blood to flow to the surface of your body, which cools down your core body temperature. Research shows that a warm shower 1-2 hours before bed can help you fall asleep and improve sleep quality, especially in the heat of summer.

3. Freeze a damp washcloth.

Soak a washcloth in water, wring, shape it into a “U” and place it in the freezer. Once frozen, this is perfect as a cooling neck wrap.

4. Freeze your sheets

Nothing beats the feeling of crisp, cool sheets. Think ahead and place your sheets in a plastic bag in the freezer in the morning.

5. Hydrate.

You’ll naturally become more dehydrated as your body sweats more, so make sure to drink enough water. Cool down further with an icy beverage, but stay away from alcohol and caffeine, which can be dehydrating.

6. Exercise mindfulness

Certain breathing techniques can help you not just manage the feelings of discomfort around heat, but help cool down your body temperature as well.

A breathing exercise known in yoga traditions as shitali pranayama feels particularly nice. Roll your tongue (or form an “O” with your lips if you can’t roll your tongue). Inhale deeply through your mouth with your tongue rolled, and exhale through your nose. Notice the cool air entering your body with that feeling of coolness on your tongue. As you breathe out, also notice warm air rising out of your stomach and leaving your body.
