Phase shifts and melatonin suppression appear to be functionally independent, researchers report.
The chances of having asthma are three times higher in teenagers who go to bed late at night compared to those who sleep earlier. The risk of allergic rhinitis is two times higher for late sleepers. Researchers say they can not be certain that staying up late is a cause for asthma, however, they note melatonin is often out of sync in late sleepers, and that could be an influential factor in the allergic response.

Breast milk may help train the circadian clock in young babies. The hormonal composition of breast milk changes throughout the day, with cortisol levels being higher in the morning and melatonin levels being higher at night.

A new study reports women who are in their third trimester of pregnancy during months with less day light are at an increased risk of developing postnatal depression.
Melatonin produced in the lungs acts as a barrier defense against SARS-CoV-2, the virus that causes COVID-19, by blocking the expression of genes that encode proteins in cells acting as viral entry points.
Overexposure to artificial light, especially from devices which emit blue light, can suppress melatonin and disrupt the circadian cycle, a new study reports.
