Long-Term Melatonin Use Linked to Higher Heart Failure Risk

A large-scale analysis of more than 130,000 adults with chronic insomnia found that long-term melatonin use—defined as one year or more—was associated with a striking increase in heart failure, hospitalization, and mortality risk. Using global health records, researchers found that melatonin users had about 90% higher odds of developing heart failure and were nearly twice as likely to die from any cause within five years.

Melatonin Linked to Improved Brain Function in Child Concussion

Researchers identified a specific neural network that positively responds to melatonin following concussion in children. Results suggest melatonin may help compensate for normal brain function that has been interrupted due to injury caused by concussion and helps prevent sleep disturbances.

Asthma and allergies more common in teens who stay up late

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.
