Turn out the light
Sunlight is a natural, positive source of energy during the day, but it can disrupt deep, restful sleep. Light – such as the rising sun – is one of the body’s most powerful time cues and can wake up the brain long before the alarm goes off.
When sleeping, is your room as dark as possible?
Is there light coming through blinds or curtains in the early morning hours?
Are the TV or hallway lights left on while you are sleeping?
Is your alarm clock brightly illuminated and facing you throughout the night?
