Yikes... now I know why I feel so awful after staying up too late.

Bright-light before bedtime disrupts preschoolers sleep patterns, study suggests

Exposing preschoolers to bright light before bedtime is not a good idea, according to a new CU Boulder study. It almost completely shuts down their production of the sleep-promoting hormone melatonin, keeping it suppressed for at least 50 minutes after light's out, says lead author Lameese Akacem with the Sleep and Development Laboratory.

Beware - Bight-light before bedtime disrupts preschoolers sleep patterns

Pulling an all-nighter just once can disrupt levels and expression patterns of more than 100 critical proteins in the blood, including those that influence blood sugar, energy metabolism, and immune function, according to new CU Boulder study that asked male participants to live like they worked the night shift for a few days. Researcher Christopher Depner, lead author of the study, says disrupting sleep patterns can very rapidly alter our normal physiology in a way that can be detrimental to our health.
