Couple sleeping

Let there be light

But not at night


The end of Daylight Saving Time requires us to reset our biological clocks as well as our household clocks. In general, gaining an hour in the fall is an easier task for our systems than losing an hour in the spring, but our personal health, sleep habits and lifestyles all influence our adjustment to time changes.

Scientists say light is the principal cue in our 24-our natural cycle, or circadian rhythm. To maintain regular sleep habits, in addition to avoiding alcohol or caffeine close to bedtime, we need to avoid nighttime light, which suppresses the secretion of the sleep inducing hormone melatonin. Is there a streetlight outside your window? Be sure to close the blinds. If you get up at night to go to the bathroom, avoid turning on the light. During the waking hours, reverse the process and try to expose yourself to as much light as possible.
