Human beings require sleep, yet they find every possible excuse to avoid getting it: playing video games, checking email, watching TV, etc. Why? Because people seriously undervalue its importance in regards to our health. We get as little as humanly possible without considering what the ramifications are, approaching sleep in a manner as out of tune with nature as we can get.
Instead of letting our bodies naturally awaken, we use alarm clocks. We can set them to go off whenever we feel like it, regardless of when we finally hit the pillow. Do you know what our great grandparents used as an alarm clock? The sun...although roosters would often play the role of middle-man. When the sun went up, they got moving and started their day. When the sun went down, they started getting ready for bed. Sure, they made fires and they would often read, sing songs or tell stories, but they certainly weren’t up until 4 A.M. chugging Red Bull and playing Xbox. And guess what? Our great grandparents were a lot healthier than we are.
So, how much sleep should we get? That depends on your age, activities, stress level, diet, etc. Most studies seem to agree that anywhere from 7-9 hours is sufficient for most people, so most people interpret that as “7 hours is enough.” Wrong. For one thing, most of these studies only look at one factor, such as alertness or the ability to perform some mental tasks with a certain degree of proficiency. However, these studies do not actually address overall health. Why? Because that is a hard thing to determine. It is your responsibility to figure out what amount of sleep is right for you.
Ideally, we should wake up when our body is ready to wake up! Of course, your boss may not appreciate your new habit of “sleeping in” but what you can do is use an alarm and be more mindful about when you go to sleep. Do a little experiment on a weekend and determine just how many hours of sleep you get before you naturally wake up, well rested.
For instance, if you notice that you can sleep 8 1/2 hours and wake up on your own and feel rested, then you should make it a point to get that amount of sleep routinely. That may mean getting to bed earlier and missing out such on watching infomercials, Seinfeld re-runs, or YouTube videos, but it’s worth it. If you have a job that includes shift work at odd hours, do your best to sneak in naps...just don't do it on company time.
So, why is sleep so important? Sleep is when your body is in repair mode. Your brain commits new experiences and information to memory. Hormones are also released. Growth occurs. Getting insufficient sleep disturbs these functions, resulting in:
On the flip side, I notice that patients of mine who don’t make an effort to get enough sleep progress slower in their care. Lack of sleep impairs healing, disrupts the nervous system, and causes the muscles to be more tense, which undermines chiropractic treatments. To quote a famous poet named Thomas Dekker, “Sleep is the golden chain that ties health and our bodies together.”
Our society views sleep as a necessary evil, an activity for the weak and the lazy. The truth is that not getting enough sleep makes you weak and lazy, both physically AND mentally. So quit abusing stimulants. Start getting more sleep. Experience better health!
