Sleep…it does the body a whole lot of good. Everyone suffers from a lack of sleep from time to time. But did you know that approximately 10% of adult Americans experience chronic insomnia (three times per week for at least three months?)

Brain Function Your brain is a highly sophisticated organ and sleep helps it function properly. As you sleep, the brain rests busy neurons (specialized cells designed to transmit information to other nerve cells, muscles, or gland cells) and forms new pathways. In addition, your brain is busy producing proteins while you sleep that help cells repair damage. Lack of sleep interferes with your concentration, ability to learn new things, gets in the way of your decision-making process, affects short-term and long-term memory and can lead to mood swings.
Immune System As you sleep, your immune system is working hard to produce infection-fighting antibodies that fight to protect your body from harmful bacteria and viruses. When you skimp on sleep, your immune system isn’t able to buildup it’s protective arsenal, leaving you vulnerable to getting sick and taking you longer to recover.
Cardiovascular System Sleep is your body’s ally when it comes to healing and repairing your blood vessels and heart. Did you know that those who are regularly sleep deprived have a 48% greater chance of developing heart disease? Functioning on too little sleep can also cause high blood pressure and lead to stroke.
