Morning StarLight can be used to compensate for changing sleep patterns, insomnia, sleep disorders, and shift work. Morning StarLight can be used to compensate for jet lag. You can wear your light screen while in flight without disturbing other passengers. 

Many persons' circadian systems do not readily adapt to night work. This results in a decline in alertness, performance, and quality of daytime sleep. This problem can be remedied with use of Morning StarLight personal/private light screen at night.

The body's internal clock, known as the Circadian system, is regulated by the pineal gland.  This gland is controlled by the presence or absence of external light, and serves to synchronize and coordinate the biological events of the body.

Melatonin, the chief hormone of the pineal gland, its produced only during darkness.  Its inhibited by light. Melatonin has sedative qualities and helps reduce anxiety, panic disorders, and migraines.  It is also thought to be a primary regulator of the immune system.

Researchers have found that when a person ignores the twenty-four-hour dark-light cycle and keeps irregular hours of work and rest, the body's internal rhythms go awry.  The number of hours one sleeps is less important than when one sleeps in respect to daylight.

People who work in rotating shifts or at night have been shown to experience a higher incidence of heart disease, back pain, respiratory problems, ulcers, and sleep disorders.  These people also have a higher rate of error and accidents and often experience a significant loss of alertness and ability to make decisions.

Travel between time zones often results in jet lag, a less serious, but often debilitating and disorienting condition caused by the upset of the body's internal clock.  Melatonin, full-spectrum, and bright light therapies are being explored as useful antidotes.  Some airports are now considering the installation of full-spectrum lights in their first class lounges to help passengers adjust to, their destination time zones.
