Hop in the shower.
You know that feeling when you step out of the shower, and into crisp air, and you feel a shiver? That’s the feeling of your body temperature dropping a few degrees—which, again, helps your fall back asleep. Our recommendation: Turn down the temperature in your room, take a quick, warm shower, and head back to bed. By the time your head hits the pillow, your room will have cooled down, helping you fall right back asleep.
