In brief: Sleep treatment

Our tendency to feel sleepy at certain times and awake other times are strongly influenced by natural body rhythms called the sleep wake circadian rhythm.
This sleep and wake cycle is strongly affected by the light that enters our eyes. Carefully timed light therapy allows physicians to adjust an individuals rhythm so that they feel more awake and alert.

It also can be used to help with seasonal affective disorder (SAD), a condition that affects some people who live in regions of the country that have short days in winter (for example, Seattle).
