Healthy Habits to Improve Your Life (cont.)
"Your body has to have enough time to rest," says Michael Fleming, MD, president of the American Academy of Family Physicians (AAFP). Otherwise, he says you may find yourself feeling cranky and tired.
This may sound like common sense, but according to the National Sleep Foundation (NSF), more than two-thirds of older adults suffer from sleep problems and many American adults don't get the minimum amount of shuteye needed to stay alert.
Sleep is vital to good health and to mental and emotional well-being. The NSF reports that people who don't get enough slumber are more likely than others to develop psychiatric problems and to use health care services. Plus, sleep deprivation can negatively affect memory, learning, and logical reasoning.
Not enough ZZZs can also be hazardous. More than one-half of adult drivers -- some 100 million people -- say they have driven drowsy in the past year, according to NSF polls. About one out of five of these drivers -- 32 million people -- say they've fallen asleep while driving.
Each year drowsy driving causes more than 100,000 car crashes, 1,500 deaths, and tens of thousands of injuries, reports the National Highway Traffic Safety Administration. The NSF recommends taking a 15 to 20 minute nap. Because it takes about 30 minutes for the caffeine to work, taking a nap while you wait for the caffeine to kick in can help restore alertness.
To avoid the pitfalls of insufficient sleep, make sure to get at least seven to 10 hours of slumber each night. Kids need more sleep, depending on their age.
Volunteer. Go to church. Join a club. Whatever you do, do it with people. Communal activities are good for your physical and mental health, according to a study published in the March/April 2004 issue of the American Journal of Health Behavior.
It makes sense, says C. David Jenkins, PhD, author of Building Better Health: A Handbook of Behavioral Change. He says social ties have many benefits, including:
Community ties also help improve mental functioning, says Fleming. Group activities can help keep the mind active and maintain desirable levels of serotonin -- the brain chemical associated with mood. "Lack of social interaction will [decrease] serotonin levels," says Fleming.
We already know that physical activity has a bounty of benefits, which makes it so puzzling why so many people just don't do it. According to the CDC, more than 60% of Americans do not get regular exercise.
In case you needed an incentive, here is a review of the advantages of exercise, per the National Cancer Institute:
Studies have also shown a link between exercise and a reduced risk of certain cancers.
Besides its long-term effects, moving your body has immediate benefits, says Cedric Bryant, chief exercise physiologist for the American Council on Exercise. The short-term results of exercise include helping people to think and move better, manage stress, improve mood, and get an energy boost.
The excuses that people often give to not exercise are the precise reasons to exercise, says Bryant. People who say they are too tired or don't have time to workout don't realize that exercise gives people more energy and allows them to be more productive with the rest of their time.
Flossing your teeth every day could add 6.4 years to your life, according to Michael Roizen, MD, author of RealAge. In his book, Roizen lists flossing as one of the most important daily activities -- along with exercise and quitting smoking -- that could extend life span.
Roizen's calculation may raise some eyebrows, but the idea that oral health is connected to overall health isn't far-fetched.
The mouth, after all, is an integral part of the body. "Teeth have a blood supply, and that blood supply comes from the heart," says Richard Price, DMD, consumer advisor for the American Dental Association (ADA).
Researchers suspect that the bacteria that produce dental plaque enter the bloodstream. They say these bacteria are somehow associated with the inflammation that occurs with plaque that blocks blood vessels and causes heart disease.
Other researchers have found links between oral bacteria and stroke, diabetes, and the birth of preterm babies and those that have low birth weight.
