Why Do Some People Need Less Sleep? Snooze News from The Zen Alarm Clock Store – Boulder, CO

Why Do Some People Need More Sleep?

Why Do Some People Need More Sleep?

New research suggests it is in our genes…

Some people are genetically programmed to need less sleep than the rest of us, according to a new paper published this week in Science. A rare genetic mutation lets its carriers function happily and healthily even with hours less sleep each night than doctors normally recommend.

Researchers discovered the enviable gene variant after studying a family in which two members, a mother and a daughter, seemed to need much less daily rest than their close relatives. The women slept just 6.25 hours per night, while others in the family averaged 8.06 hours. The researchers then sequenced some genes they thought could be responsible, and discovered that both mom and daughter — unlike others in the family — had a never-before-seen mutation in a gene that’s known to affect circadian rhythms.

Next, to test whether that gene variant was really the cause of mom and daughter’s shortened sleep time (and not just some freak coincidence), the researchers genetically engineered a group of mice to express the newly found mutation. Sure enough, those mice had a typical activity period that’s more than an hour longer, on average, than that of a normal mice. The mutant mice also seemed to need less catch-up sleep than others after a period of sleep deprivation.

The new findings give a fascinating insight into why humans vary so much in how long we sleep — with a good night’s shut-eye ranging anywhere from six hours to nine, depending on whom you ask. But the result can hardly explain everything. This new-found gene variant appears in just 1 in 60 families that were studied, according to a follow-up paper that’s also published this week in Science. For genes to explain the full range of human sleep needs, then, there would have to be other genes involved too.

Our Digital Zen Clock’s long-resonating Tibetan bell-like chime makes waking up a beautiful experience – its progressive chimes begin your day with grace. When the clock’s alarm is triggered, the acoustic chime bar is struck just once … 3-1/2 minutes later it strikes again … chime strikes become more frequent over 10 minutes … eventually striking every 5 seconds until shut off. As they become more frequent, the gentle chimes will always wake you up – your body really doesn’t need to be awakened harshly, with a Zen Clock you’re awakened more gradually and thus more naturally.  Unlike artificial recorded sounds coming out of a tiny speaker in a plastic box, natural acoustic sounds transform your bedroom or office environment.

The Zen Alarm Clock transforms mornings, awakening you gradually with a series of gentle acoustic chimes Once you use a Zen Clock nothing else will do.
