11. Sleep In a Cold Room
The next time you head to the thermostat to turn it up before bed, then you might want to hold off. Science has demonstrated that it’s easier for people to fall asleep if their bedrooms are cold, and a cold room helps people fall asleep faster at night. Why? Because your core body temperature naturally falls a degree or two when you’re sleeping, so dropping the temperature in your room will help your core do that much faster. This sleeping trick also helps people with insomnia because those who do tend to have higher body temperatures, too, so keeping it down will help them drift off more easily.
