How to look refreshed when you wake up
Let in natural light.
Sunlight, or an artificial alternative, helps your body accept the awakening. Not only will you wake up easier, but you'll reset your body's clock, feel better rested, and improve your mood.
Do some exercise first thing in the morning. Exercise increases body temperature and releases endorphins that help you awaken.
