Although most people get around five to seven hours of sleep a night, experts caution that number should really be somewhere closer to eight hours of sleep. "The problem with being chronically sleep-deprived (as in, missing one to two hours nightly) is that the body perceives the sleep loss as a "stress," which increases levels of stress hormones, such as cortisol (which interferes with insulin function)," says Shawn Talbott, nutritional biochemist and author of "The Secret Vigor: How to Overcome Burnout, Restore Biochemical Balance, and Reclaim Your Natural Energy."

That means blood sugar regulation is compromised and you'll crave more sweets and junk food. The increased appetite for unhealthy snacks puts you at risk for abdominal weight gain, diabetes and obesity. Yikes!

Not only can enough sleep keep you at a healthy weight, it can also help prevent medical illnesses.

Daniel Cohen, a holistic health and wellness counselor, suggests the following tips to help you get more sleep:

Get into a routine. Try going to bed half an hour earlier each week or set a bedtime. This will get your body used to a schedule.

Relax before bed. Turning the television off and taking some time out for yourself before bedtime, whether it be relaxing with a good book or meditating. This will help reset your brain and get it into sleep mode.

Cut out the caffeine! As we all know, caffeine keeps us stay alert and ready to start the day. If you are the type of person that gets a jolt from caffeine, cutting it out four to six hours before bedtime can help ensure that you get a restful night's sleep.

Eat a high-protein snack before bed. This can provide the L-tryptophan your body needs to process melatonin and serotonin.

Avoid alcohol You may think that having a drink before bed might make you sleepy, but the effects are short lived. You will often awake several hours later, unable to fall back to sleep.
