2. Turn Down Your Thermostat
Make sure your room is cool at night. A cooler room will help decrease your body temperature, which is essential for battling insomnia. The soundest sleep happens in a room that's around 60 to 67 degrees F (15 to 19 degrees C), according to the National Sleep Foundation.

If you have a ceiling fan, consider cranking it up to help cool down your bedroom, particularly during the summer months. An added bonus? The air circulation will be beneficial for your nighttime breathing.
