Transplanted bacteria from sleep-apnea mice caused sleep changes in recipient miceCredit: None Obstructive sleep apnea (OSA) is a chronic sleep condition affecting more than one billion people worldwide. Evidence suggests OSA can…

Conducted by the University of Leicester and the University of South Australia, the study assessed the bedtime preferences (sleep chronotypes) of people with type 2 diabetes, identifying a connection between bedtimes and healthy, active…

BACKGROUND Tracking the passage of time to the second is critical for motor control, learning and cognition, including the ability to anticipate future events. While the brain depends on its circadian clock to measure hours and days, the…

When it comes to metabolic health, it's not just what you eat, it's when you eat it. Studies have shown that one effective means of losing weight and tackling obesity is to reduce the number of hours in the day that you eat.…

Renowned scientists will address topics as chronobiotics, circadian rhythms, the timing of societies, and well-being. The São Paulo School of Advanced Science Ecology of Human Sleep and Biological Rhythms will be held August 2-12, 2021 in…

Research from the University of Kent has found that TRESK, a calcium regulated two-pore potassium channel, regulates the brain's central circadian clock to differentiate behaviour between day and night. Research from the University of Kent…

DARIEN, IL - Seeking medical care after springing forward to daylight saving time could be a risky proposition. Researchers at the Mayo Clinic found a statistically significant increase in adverse medical events that might be related to…

DARIEN, IL - Public health and safety would benefit from eliminating daylight saving time, according to a position statement from the American Academy of Sleep Medicine. The AASM supports a switch to permanent standard time, explaining…

DARIEN, IL - Men might want to think twice before reaching for their smartphone at night. A new study found correlations between electronic media use at night and poor sperm quality. Preliminary results show that greater self-reported…

It's hard to get a good night's sleep in space. An evaluation of astronauts serving on the Mir space station found that they experienced shorter sleep durations, more wakefulness, and changes in the structure of their sleep cycles while…

Research looks at sleep optimization to improve glycemic control Getting more sleep and establishing a regular sleep schedule is a common recommendation for maintaining and improving health, including for people with Type 1 diabetes. Short…
