Changes in Your Brain
One of the first things you’ll notice when you aren’t getting enough quality sleep is the effects on your brain. You’ll start to get headaches, be moody, have memory issues, and have trouble concentrating and thinking. These effects can be very frustrating, which leads to stress and more of the same.
During sleep, your body releases a fluid that washes over your brain, called cerebrospinal fluid. This fluid has many purposes, but one of its primary functions is to clean the brain of toxic proteins while you sleep. Unfortunately, this bath doesn’t happen the moment you fall asleep. It happens during deep sleep, so you have to get through two other stages before reaching it. Then, it happens several times per night. Just once isn’t enough. If toxic proteins are allowed to build, you’ll experience memory issues, trouble concentrating, and maybe even early dementia or Alzheimer’s Disease. Sleep deprivation can actually age your brain by 3-5 years!
Your mood will also suffer from not getting enough sleep. You’ll feel stressed, irritable, frustrated, and sad which can lead to depression and anxiety.
