Study links fish consumption with higher IQ, better sleep

Study links fish consumption with higher IQ, better sleep

Health
Dec. 21 (UPI) -- Kids who eat fish at least once a week score higher on IQ tests and experience better sleep, according to new research by scientists at the University of Pennsylvania.Omega-3s, fatty acids found in fish, have previously been linked individually to boosts in intelligence and improved sleep. But the latest study -- published this week in the journal Scientific Reports -- is one of the first to examine the relationship between all three variables."This area of research is not well-developed. It's emerging," Jianghong Liu, an associate professor of nursing and public health at Penn, said in a news release. "Here we look at omega-3s coming from our food instead of from supplements."The study included 541 children in China, ages nine to 11, 54 percent boys and 46 percent girls. ...
What to eat, and what not to eat, for a good night's sleep

What to eat, and what not to eat, for a good night's sleep

Health
How well you sleep can have a significant impact on your overall health, and not getting enough sleep has even been linked to overeating, according to ABC News' senior medical contributor, Dr. Jennifer Ashton. Ashton appeared live on "Good Morning America" today to share why it is so important for adults to get seven to nine hours of sleep a night, saying that insufficient sleep impacts your hunger and fullness hormones. When you're not getting enough sleep, the level of ghrelin, the hormone that tells your brain when it's time to eat, increases. In addition, the level of leptin, the hormone that tells your brain when to feel full, decreases. As a result, sleep deprivation can lead to overeating and gaining extra pounds, according to Ashton. If you find yourself especially hungry late...
What parents should know about sleep apnea in children

What parents should know about sleep apnea in children

Health
Medical experts are warning parents that if you hear your young son or daughter snoring, it could potentially be a sign that the child is suffering from sleep apnea. "It should raise a flag," Dr. Sydney Butts, an ear, nose and throat doctor in New York City told ABC News of snoring in children. "You should think about watching some other signs and symptoms that may kind of sound the alarm." "It's not a problem restricted to adults," Butts added of sleep apnea. "It's actually one of the most common reasons why children need their tonsils or adenoids removed." If untreated, sleep apnea can lead to chronic heart failure, stroke, high blood pressure, obesity and other health problems, according to the American Sleep Apnea Association (ASAA). Kevin and Amanda Cook told ABC News that three ...
Poor sleep habits increase risk for obesity, study says

Poor sleep habits increase risk for obesity, study says

Health
FRIDAY, Aug. 4, 2017 -- Something else to fret over as you lie awake at night: Poor sleep may increase the risk of being overweight and obese, a new study contends."Because we found that adults who reported sleeping less than their peers were more likely to be overweight or obese, our findings highlight the importance of getting enough sleep," said the study's senior investigator, Laura Hardie, of the University of Leeds in England."How much sleep we need differs between people, but the current consensus is that seven to nine hours is best for most adults," Hardie said in a university news release.For the study, the research team looked at more than 1,600 adults in the United Kingdom. The participants reported how long they slept and kept records of what they ate. The participants also had...
How and why does light affect sleep?

How and why does light affect sleep?

Science
June 23 (UPI) -- Many studies have explored the effects of light on the circadian rhythms of plants and animals, including humans. But few have looked at the direct effects of light on sleep.Researchers at the California Institute of Technology set out to determine how and why light directly impacts sleep. Scientists wanted to know why darkness is soporific, and why brightness can disrupt deep sleep.Testing in Caltech labs revealed a light-sensitive neural protein key in maintaining the proper balance between wakefulness and sleep."Researchers had previously identified the photoreceptors in the eye that are required for the direct effect of light on wakefulness and sleep," researcher David Prober, a professor of biology at Caltech, said in a news release. "But we wanted to know how the bra...
