Why Sleep Is Important
Interestingly, the effects of sleep, or lack of it, are evident the very next morning. Like most of us, you’ve probably had days when you just didn’t want to get out of bed. More likely than not, it was because of going to bed late the night before.
While it may not seem like it, your body is very active while you slumber. It is during this time that most of the rebuilding and repairing of damaged tissues happen. This is also when your body secretes growth hormones.
So, getting the right amount of right nightly helps prevent long term conditions such as heart disease and diabetes. If you’re still growing or want to build muscle, sleep is something you don’t make to skimp on. Sleeping on a comfortable and supportive mattress is important, too.
I remember my younger days when I thought of sleep as something that I needed to do when I got tired at night. Looking back, that wasn’t a good idea.

Studies show that poor sleep quality is linked to migraines and headaches. Between 36 to 58% of people with sleep apnea wake up with headaches.
