Other times, however, you set yourself up for failure. By going to bed too late (or waking up too early), not letting your mind calm down, or not sticking to a routine, you could actually be causing un-restful sleep through your habits. Because, without enough deep, productive sleep, your body just can't function like it should. Your brain isn't as quick, causing you to be slower with reactions, speech, and even body functions. In fact, reduced sleep, over time, can cause brain damage, memory loss, and have an effect on everyday mood. Just like we need sleep after a long day, the brain needs time to rest and recharge itself.
Think of it like a battery. It's best to charge a phone, computer, etc. on a routine – once it's low, charge it completely. Failing to do so, or charging a little here and there can lower the battery's quality. Other times, a battery can be just fine – they, like the brain, are prone to different factors.
However, by keeping a regular charge, or sleeping on a schedule, you can do your best to combat these negative side effects. Talk with your doctor or set a regular routine in order to give the brain, and the rest of the body, as much rest as possible.
