Seek Out Light
According to the National Institute of General Medical Sciences, light is the main cue influencing circadian rhythms, turning on or turning off genes that control your internal clock. Roll up your shades as soon as you’re awake. If you can’t get natural light in your bedroom, consider a lightbox or alarm that slowly gets brighter, simulating dawn. If you don’t want to get that fancy, just flip on a regular light as soon as you get up.
