Researchers have found genetic mutations linked to short sleep
Unbothered after a few hours of sleep? Studies suggest that not everyone may need seven or eight hours as generally recommended.
Adults aged between 18 and 60 should aim for seven or more hours of sleep per night, according to recommendations from the Centers for Disease Control and Prevention (CDC).
"Not getting enough sleep is linked with many chronic diseases and conditions-such as type 2 diabetes, heart disease, obesity, and depression-that threaten our nation's health," the "Not getting enough sleep can lead to motor vehicle crashes and mistakes at work, which cause a lot of injury and disability each year."
People's internal clocks could be off by hours from one another, perhaps explaining why some are early to rise, while others prefer to stay up late.
The report also referenced a small study out of Sweden, which found that men who exercised at 8 a.m. had higher levels of blood sugar than men who worked out at 4 p.m., hinting that exercise may have heightened benefits at certain times during the day.
