You Can't Get Too Much Sleep

The body’s major restorative functions "like muscle growth, tissue repair, protein synthesis, and growth hormone release occur mostly, or in some cases only, during sleep," Harvard Medical School explains. It makes sense that athletes who tax their muscles more than the average person need more sleep to fix the damage. It appears that extra, above eight-hour sleep benefits athletes rather than contributing to an early demise. "You can never get 'too much' sleep," University of Pennsylvania sleep researcher Dr. Sigrid Veasey wrote Outside in an email. "When you have had enough sleep you will wake up." 

(And you'll be more alert and have improved cognitive function if you're getting eight hours, she adds)

So where does the seven-hour ideal come from? Support for the less-is-more position has been building since 2002, when researchers published a studyinvolving more than 1.1 million people. In it, scientists concluded that people who sleep about seven hours a night live longer than those who get more or lesszzz's. In fact, sleeping longer than eight hours a night, the researchers noted, is associated with health issues such as diabetes, obesity, and cardiovascular disease.  

"It is important to understand that this 7 vs. 8 hours finding was not a carefully controlled study but is an association found retrospectively…this pertains only to longevity," Veasey wrote. It’s entirely possible that illness caused people surveyed to sleep longer, not the other way around. 

"You can never get 'too much' sleep"?! Challenge accepted!

Okay, not really.

So the key is to get at least 7 hours a night? 

this is great news!  in fact, i think i'll give it a try... starting now.

You're going to try to sleep 7 hours?

Or you're going to try to get too much sleep?

well, i was going to try to get too much sleep, but in an ironic twist, my children woke me up twice, wanting to chat and pee and whatever, so i got less than 7!!

No parent in history has ever gotten too much sleep.

so... yawn... true!

Challenge accepted!

Fun fact: LeBron likes 12 hours of sleep.

Bottom Line: How much is "enough" varies from person to person. While some people may thrive on seven hours of sleep, others may need nine to shine. If you’re active, science says you should aim for at least eight. But if you get more, you’ll likely be doing your athleticism a favor; Lebron James and Roger Federer reportedly sleep 12 hours a night. And, you know, they’re pretty good. 

that IS a fun fact!  12 hours?!  i don't even know if my body can DO that?!  maybe if i exercised as much as lebron...

Yeah, if you exercised for 8 hours you could sleep for 12. :)

8 hours of exercise is no joke!

8 hours of ANYTHING is no joke!

except sleep.

Sleep is no joke, too, apparently!
