Using the relatively simple clocks found in fruit flies, researchers reveal that the subcellular location of clock proteins and genes fluctuates with the daily passage of time, indicating that spatial information is translated into time-related signals. Source

A new meta-analysis assessed data from 15 published studies to see how a single session of intense exercise affects young and middle-aged healthy adults in the hours prior to bedtime. And while no two bodies are the same, the researchers did find that the combination of factors would interact to enhance or modulate the effects of exercise on sleep. Source

Adults and children with migraines may get less quality, REM sleep time than people who don’t have migraines. That’s according to a meta-analysis. Children with migraines were also found to get less total sleep time than their healthy peers but took less time to fall asleep. Source

Missing out on the recommended seven or more hours of sleep per night could lead to more opportunities to make poorer snacking choices than those made by people who meet shut-eye guidelines, a new study suggests. Source

Researchers have identified an association between early lower respiratory tract infections and the development of obstructive sleep apnea in children. Source

Men’s sleep may be more powerfully influenced by the lunar cycle than women’s, according to a new study. Source

Researchers have shown that people with inflexible metabolisms burn less fat at night than those with flexible metabolism. The team measured the respiratory quotient throughout the night and found that despite equal ages, BMIs, and amount of fat, people with inflexible metabolisms burned more carbohydrates and less fat than did people with flexible metabolisms. The higher sleep-time quotient could be a previously unknown indicator for the risk of future metabolic disease. Source

Good sleep-time recovery is associated with a health-promoting diet and health-promoting eating habits, as well as with lower consumption of alcohol, according to a new study investigating psychological and physiological well-being among working-age Finnish adults. Source

For hundreds of years, people have observed that asthma severity often worsens in the nighttime. One longstanding question has been to what degree the body’s internal circadian clock — as opposed to behaviors, such as sleep and physical activities — contributes to worsening of asthma severity.

After 7 days of recovery from a 10-day period of deficient sleep, participants in a small study had recovered their pre-sleep deprivation reaction speed, but had not fully recovered on any other measures of function. Source
