For millions of Americans, shedding unwanted pounds is a top priority. That's why the National Sleep Foundation (NSF) is reminding Americans that spending more time between the sheets may be part of the secret to slimming down and looking great.
People tend to forego sleep in order to make time for a work-out or other daily activities and it is often overlooked as an important factor in the battle of the bulge.
Many do not realize that skimping on sleep can actually make it harder to lose weight, says Meir H. Kryger, MD, Chairman of NSF's Board of Directors. Research suggests that even a modest amount of sleep deprivation can increase appetite by altering the behavior of the hormones leptin and ghrelin, which are responsible for regulating appetite and metabolism. As a result of sleep loss, people may experience stronger cravings for carbohydrates and calorie-rich comfort foods such as cookies and chips, which can lead to weight gain.
Recent research suggests that people who sleep less may also produce more insulin, which puts them at higher risk of developing Type 2 Diabetes. Diabetes and obesity are both on the rise in the U.S., resulting in serious health complications for many Americans. "Healthy sleep is a part of an antidote for the obesity and diabetes epidemics in America," says Kryger.
In addition to mounting scientific evidence, the results of the NSF's 2008 Sleep in America poll, released in March 2008, suggests that sleep loss and obesity are linked. According to the poll, people who are overweight/obese are more likely than people of normal weight to spend less time in bed on workdays (6.82 hours vs. 7.12 hours) and to sleep less than 6 hours per night (17% vs.12%).
NSF's 2008 poll also reveals that having a weight problem can have a negative impact on one's health and safety. According to the results, those who are overweight/obese are more likely to:
For people with sleep disorders, getting adequate sleep may require the help of a healthcare professional. But for many Americans, healthy sleep can be achieved with just a few simple steps. Try these tips for better Zzzs:
Make sleep a top priority - Getting optimal sleep allows you to feel your best and be productive. Healthy sleep also helps to regulate your metabolism.
Maintain a consistent sleep schedule - Going to bed and waking up at the same time every day keeps your biological clock in tune.
Establish a relaxing bedtime routine - A regular routine, such as having a bath or listening to soothing music, can help you fall asleep and stay asleep.
Use your bedroom only for sleep - Clear your bedroom of distractions such as computers, phones and other "sleep stealers" in order to create a positive sleep association with the bedroom.
Avoid foods and drinks high in caffeine - These (coffee, colas and tea) should be avoided for at least 6 hours prior to bedtime, and avoid alcohol for a few hours before bedtime.
Exercise regularly - However, finish your workout at least 4 hours before bedtime.
If you are experiencing a sleep problem, such as difficulty falling asleep or staying asleep, or if you suffer from chronic daytime sleepiness despite allowing adequate time for sleep, talk to your healthcare professional.
