It doesn't get much more free than sleep! Though it does often require some equipment, i.e. a bed, covers, maybe a pillow, these can and are often improvised, and are generally readily available. So what? How does sleep affect me achieving my fitness goals?
Over the past week I have seen a handful of articles about sleep over on another one of my favorite sites,
LifeHacker.com. LifeHacker isn't so much about health and fitness, but about all sorts of ways to make life easier, better, and more enjoyable, from making your computer easier to use and more useful, to saving money on groceries, to dressing well, to getting a better salary. I think we can all agree that sleep makes our life better, but what is the best way to maximize on this commodity?
Implement Advanced "Siestas" for Improved Sleep talks about how we can get the most out of the day by sleeping in intervals instead of one long span. Though it shows several examples of various amounts and intervals of sleep, the most extreme has you taking 6 20-minute naps a day. Thats just 2 hours of sleep! Think of all you could do with the time freed up by not being in bed so long. Since a lot of people use lack of time as an excuse for not exercising or taking the time to cook healthy meals instead of eating fast food, this certainly could be a health benefit if used properly. And since you are active more hours of the day, you are burning more calories, too, right?
The above article and many others like it suggest the premise that our brains mainly need the REM cycle of sleep and if we sleep more effectively, meaning we get our brains the REM time they need, then we can waste less time in bed. But what about our bodies? Sleep is when our bodies can most effectively repair themselves, and that is not just during the REM phase. And let's face it, the older we get the more our bodies need to repair themselves. Whether it be fighting off the cold that is going around the office, or the stretched calf muscle from running to catch the bus, our bodies are constantly repairing, and when we are asleep is the best time for that. To add to the everyday repairs that are ongoing in our bodies, if we are exercising regularly, as we should, then our bodies will also be repairing muscle we have been using, especially if we are trying to build muscle. Not a coincidence, then, to see this article:
"Sleep Load" for Improved Training Performance, also on
LifeHacker.com:
| "Wells blogger Tara Parker-Pope references a Stanford study that found all athletes involved performed better on their drills after increasing their sleep times. Specifically, improvements were observed after the athletes extended their sleep to 10 hours a night for five to six weeks. Ten hours is probably more sleep than many of us can afford, but the study still demonstrates just how much sleep matters to your performance." |
Though my biased opinion is definitely in favor of the "more sleep" theory, it is nice to know how flexible and adaptive the human body is. Either way you look at it, though, something that will help make the most out of 20-minute naps or 10-hour hibernation is to
Improve Your Sleep Posture.
