It's not the late nights, but the smoking and drinking that happen during those late nights, that are killing people who are "night owls"earlier in life, a new study claims.

Researchers studied twins in Finland for 37 years, looking at different chronotypes, the body's natural inclination to sleep at a certain time.

It is already known that getting enough sleep is vital to good health, but now new research suggests that having a sleep disorder is linked to suicidal thoughts in children, teens and young adults.

Treating these sleep issues could be an inroad to improving their mental health, the study authors suggested.

"People so often think of sleep disorders as being a symptom of other mental ...

Going to bed earlier is one way for teens to get the sleep they need, new research suggests.

That may be easier said than done, the researchers admitted. But their study shows that if you can get teens to go to bed earlier, they will increase their time asleep by 41 minutes for each additional hour in bed.

"The idea that there's a circadian phase delay that prevents teens from going...

After many nights of tossing and turning, you might have more to worry about than just feeling exhausted and less sharp at work.

Researchers have found another clue as to why some infants die suddenly in their sleep, and it's related to a faulty chemical receptor in the brainstem.

Experts said the findings provide another puzzle piece in understanding the root causes of sudden infant death syndrome (SIDS).

By examining autopsied brain tissue, researchers found that a particular chemical receptor was altered ...

Lightbulb inventor Thomas Edison believed a little shuteye could boost his creativity. Contemporary scientists think the iconic innovator was on to something.

But timing is key, they say.

"We found a strong effect of 'sleep onset' on creativity,"said study author Kathleen Esfahany, an undergradua...

Poor sleep brought on by sleep apnea may ultimately undermine the brain health of older men and women, new research suggests.

The concern stems from a new brain scan investigation that involved 140 sleep apnea patients.

"Sleep apnea is a medical condition in which patients ... stop breathing during sleep, which can affect their sleep quality by causing multiple arousals and dropping...

Getting good sleep is an important part of wellness for many reasons, but new research suggests deep sleep may even guard against memory loss linked to Alzheimer's.

While disrupted sleep has been linked with accumulating beta-amyloid plaques in the brain faster, scientists found that superior amounts of deep, slow-wave sleep can be protective against memory decline in those with a high bu...

Changing the clocks every spring and fall might seem challenging, but a new study reveals that only one of those changes had a tendency to increase sleep disorders.

The transition from daylight saving time to standard time in the fall -- when people gain one hour overnight -- was associated with a brief rise in sleep disorders, including difficulty going to sleep or staying asleep.

Add airplane noise to the list of issues keeping people up at night, at least for those who live near U.S. airports.

Researchers found that exposure to airplane sounds -- even at moderate levels -- increased the odds of short sleep.

They reported that people exposed to airplane noise levels as low as 45 decibels (dB) tended to sleep fewer than seven hours a night.

Really, 45 d...

If you're longing for a nap, try to keep it short.

Researchers found that siestas of 30 minutes or more in Murcia, a region of Spain, where it's common to nap, were linked to a higher risk of obesity, a group of conditions called metabolic syndrome and high blood pressure.

"Not all siestas are the same. The length of time, position of sleep and other specific factors can affect t...

When U.S. health officials reported a 500% spike in the number of poison center calls involving kids eating melatonin gummies last year, Harvard researchers decided to take a closer look at the sleep supplements and discovered a disturbing fact: They contained up to 347% more melatonin than the label stated.

What's more, five of the products also contained CBD in higher amounts than the l...

Need to get your shut-eye on time? What you eat could make a difference, according to a new study.

Researchers found that college athletes who ate more carbohydrates and vitamins B12 and C tended to go to sleep and wake up earlier.

It's possible that these nutrients might increase synthesis of vital hormones that regulate sleep, including serotonin and melatonin, the authors said.

Taking a particular sleep medication may help stave off Alzheimer's disease, but it's too soon to say for sure after a preliminary study.

Researchers at Washington University School of Medicine in St. Louis found that participants who took a sleeping pill called suvorexant before bed had a drop in levels of key Alzheimer's disease proteins.

"This is a small, proof-of-concept study. ...

Consistently good sleep is important for everyone, but it is particularly important for patients with schizophrenia, a new study suggests.

Researchers from the University of Pittsburgh, along with collaborators in Italy, used wrist monitors to measure activity and rest in 250 people, including 150 patients with schizophrenia, in both outpatient settings and in psychiatric hospitals.

Early-career doctors were more likely to make mistakes when they had long work weeks or extended shifts, new research reveals.

Their patients were also more likely to experience adverse events as a result, according to the study. Moreover, doctors in their second year of training or abo...

Daytime naps longer than a half-hour appear to nearly double a person's risk of developing an irregular heartbeat, a new study reports.

People who nap 30 minutes or more a day have a 90% higher risk of developing the heart rhythm disorder atrial fibrillation (a-fib) than those who take shorter naps, according to research presented Thursday at a meeting of the
