A good night’s sleep is important for weight control and focus among other health issues.  In this video, Robin Miller, MD shares what can happen with sleep deprivation.
There are several benefits to obtaining a good night's sleep. Improved energy, mood and memory are just a few of the benefits. Sleep allows the brain to process information and form memories. Lack of sleep can affect a person's ability to learn and focus on a task.

Regularly sleeping enough helps with everything from keeping your energy up to keeping your weight down. Getting at least 6 hours of sleep a night -- but no more than 9 hours -- can make you look and feel 3.4 years younger.

Getting a good night's sleep is an effortless technique to create longevity and health. Deep rest during the night helps you fight stress, maintain a healthy weight, and keeps your energy levels high. Timing your sleep is like timing an investment in the stock market -- it doesn't matter how much you invest, it matters when you invest.

While occasional sleep loss is bothersome, chronic problems can take a toll on the body. No one understands fully why the body sleeps, but there are certain functions that restore and refresh the body. Your blood pressure decreases; heart rate slows; appetite, stress and insulin hormones quiet; and blood clotting cells take a break. Keep the body awake and you are subject to weight gain, heart disease, mood disorders, decreased immunity, insulin resistance and diabetes.
