I do bright light therapy.

I associate night shift work with circadian rhythm disorders, extreme working hours and tumors.

I lost my circadian rhythm during extreme night shift work and I restored it by using continuous light therapy. I was waking up at sunrise with the birds, no alarm clock needed.

I improved my sleeping circadian rhythm with red and infrared light exposures.

Continuous daytime full spectrum light therapy restored my circadian rhythm and I was waking up at sunrise with the birds.

Circadian Rhythm Disorder was a health risk during the COVID-19 lock down.

I lost my circadian rhythm during extreme night shift work atop the very high altitude mountain of Mauna Kea in Hawaii. Waking up in the morning, staying awake during the daytime and sleeping has been problematic ever since.

If you are not naturally waking up at sunrise, then it is likely you have some form of Circadian Rhythm Disorder.
