Bipolar disorder can be treated with drugs and psychotherapy. Certain chronotherapies — approachings designed to harness and normalize the body’s natural lilts, such as light cares — may help too, according to a recent systematic review of research.

Why might illuminate therapies facilitate?

Circadian tempi, our natural 24 -hour clocks, are stopped in bipolar illness. In addition, parties with bipolar disorder seem to be more sensitive to light.

One way of treating bipolar disorder is to manipulate the circadian rhythm. This can be achieved with bright light care, obscurity therapy, sleep hardship, and certain types of psychotherapy.
