Doctors: Taking Melatonin for This Long Was Just Linked to a 90% Increase in Heart Failure Risk
A breaking study has linked long-term use of this popular supplement to a staggering heart risk increase. Still, you may not have to give it up for good.
Hidden bacterial molecules in the brain reveal new secrets of sleep | ScienceDaily
New studies show that a bacterial molecule, peptidoglycan, is present in the brain and fluctuates with sleep patterns. This challenges the idea that sleep is solely brain-driven, instead suggesting it’s a collaborative process between our bodies and microbiomes. The theory links microbes not only to sleep but also to cognition, appetite, and behavior, pointing to a profound evolutionary relationship.
Scientists shed new light on the mysterious memory-altering power of sleep
Scientists found that sleep plays an active role in transforming how memories are stored. After an immersive experience, participants remembered the order of events better after sleeping, suggesting the brain prioritizes storylines over details during deep sleep.
Long-term melatonin use linked to 90% higher heart failure risk
People with chronic insomnia who used melatonin long term had a roughly 90% higher risk of developing heart failure over five years, according to a large preliminary study.

If you get sleepy around the same time every night and use an alarm clock to wake up in the morning, your body’s likely used to some sort of sleep routine. T...
Sleep Deprivation Affects Cognition via Myelin Loss
A new study links sleep loss to the thinning of the myelin layer, which slows signal transmission in axons. Restoring cholesterol homeostasis reverses this.
Pink Noise May Disrupt REM Sleep and Harm Sleep Quality, Researchers Say
A recent study suggests that pink noise may interfere with REM sleep nd reduce overall sleep quality. The researchers say that using earplugs may be a safer alternative to pink noise.
Sleeping less than 7 hours could cut years off your life
Sleep isn’t just about feeling rested—it may be one of the strongest predictors of how long you live. Researchers analyzing nationwide data found that insufficient sleep was more closely tied to shorter life expectancy than diet, exercise, or loneliness. The connection was consistent year after year and across most U.S. states. The takeaway is simple but powerful: getting seven to nine hours of sleep may be one of the best things you can do for long-term health.
Taking Melatonin Could Raise Your Risk of Heart Failure, Study Finds
New research suggests that people with insomnia who use melatonin supplements for more than a year have a higher risk of heart failure than those who don’t use the popular sleep aid.
