How important is sleep really? Well to start off, sleep plays a huge role in your physical health. There are 50-70 million people in the U.S. that suffer from insomnia. Not to mention, the people who over sleep and abuse it.
Sleep effects the heart. For people getting 6 hours or less a day, they are 48% more likely to suffer from heart disease, 15% more likely to develop a stroke, and weight gain. The longer you are awake, the hungrier you become, since your body needs more energy to sustain you. When you are sleep deprived, it makes your immune system weaker. This means you are more likely going to get sick.
What about your mental health?
During sleep, your brain functions in two different ways. First, there is slow-wave sleep (SWS), also known as deep sleep. Secondly, there is REM (Rapid Eye Movements) sleep, also known as dreaming sleep. Here the body increases to levels measured in people who are awake. This stage of sleep helps to enhance learning and memory. It also contributes to emotional health.
