More Reason to Connect

Not only is it fun to spend time shopping with friends or visiting with loved ones—researchers now know that time can also help keep your brain healthy as you age.

Some research indicates that people who have good social networks live longer. They also are physically healthier than people who are socially isolated. In fact, experts say that how socially connected a person tends to be is one of the most important ways of predicting his or her health and independence in later years.Maintaining supportive relationships is an important element of effective aging. The more contact we have with others as we age, the better we may be at retaining mental sharpness.

A large study reported in the New England Journal of Medicine found that people who engaged in leisure activities such as learning to play a musical instrument or dancing were less likely to develop dementia.Dancing may be especially beneficial to the brain because it combines physical activity with social interaction, and often involves a cognitive challenge in learning dance steps.

“There’s a lot of evidence that other people are the most unpredictable things you can encounter,” says Lawrence Katz. “So activities that have you engaging with other human beings are a fantastic form of brain exercise.”Other studies suggest that people with the most limited social connections are twice as likely to die over a given period as those with the widest social networks. Many experts believe that social isolation may create a chronically stressful condition that accelerates aging.

This information is especially important to older people, who may be more likely to lead solitary lives—especially if family and friends have moved away or died. Of course, combating loneliness requires time and energy, both in establishing new relationships and in deepening existing ones. But the benefits are well worth the effort.

The Healthiest Time to Do Everything, Pt 3

In the past few days, we have discussed the healthiest times to workout, best times to seek medical care, and the timing of prescriptions. Today, in part 3, we will look into the healthiest times to boost your energy and brain power.

Part 3 of 3 - Best times to Boost your energy and brain power


Head to bed at least 3 hours after dinner
It ensures more efficient digestion and, because eating too much food before sleeping can cause heartburn, deeper sleep, says Foresman. If you want a cocktail, have it with dinner to give your body plenty of time to metabolize the alcohol. Even if a drink makes you feel sleepy at first, just one nightcap can cause you to wake up more frequently during the night, finds a study from Wake Forest University. Imbibing too late in the evening upsets normal brain patterns, delaying REM (dream) sleep. Later, when REM rebounds, you'll be more likely to have startling, vivid, or violent dreams, which can also disturb sleep, says Joyce A. Walsleben, PhD, an associate professor at New York University's Sleep Disorders Center and coauthor of A Woman's Guide to Sleep.


Follow a sleep schedule
Several studies suggest that obeying your alarm clock can help relieve daytime fatigue. Sleep researchers are finding that people who get at least 7 hours of sleep a night are much less likely to be obese—and weight gain can act as an energy drain. Going to bed and getting up at the same time every day also keeps your biological clock on schedule. This clock, a cluster of 20,000 neurons in your brain, regulates your body's temperature, hormones, blood pressure, and other important functions. Throw it off-kilter and you could face serious health problems: Studies on night-shift workers suggest that people with irregular sleep habits have an increased risk of digestive troubles, emotional and mental problems, heart disease, and cancer, says Foresman.


Take vacation in late February or early March
And head outdoors. By March, as many as 50% of people not living in the Sun Belt will already have had a few months of winter-induced mood dips, says Matthew Edlund, MD, director of the Center for Circadian Medicine in Sarasota, FL, and author of The Body Clock Advantage. March is also the month when the more extreme psychological slump known as seasonal affective disorder, or SAD, can become overwhelming for the estimated 10 million sufferers in this country.
By taking a break somewhere sunny, you can "reverse your emotional course," reports Edlund. Warmth isn't required to garner a mood boost: Hitting the ski slopes can be as uplifting as heading south. The key is to use the great outdoors—plan an active vacation that maximizes your exposure to daylight.


Take a nap at 2 PM
The dip in body temperature that helps ease you into sleep at night also occurs midday, which is why afternoons can be so unproductive. But if you can catch a catnap around 2 PM (the slump usually hits between 1 and 3 PM), it should boost your alertness for several hours. Ten minutes will do the trick—nod off for more than 20 and you may wake feeling groggy. If a nap is out of the question, eat plenty of protein at lunch, which will give you longer-lasting energy, says Christine Gerbstadt, MD, RD, a spokesperson for the National Dietetic Association. Mid-afternoon is also a good time for "strategic caffeine use," says Brian Foresman, DO, director of the Sleep Medicine and Circadian Biology Program at Indiana University School of Medicine. "If you don't exceed a cup or two per day, caffeine works phenomenally well at increasing your alertness." This should be your last cup of coffee for the day, though—any caffeine consumed within 7 hours of bedtime can disrupt your sleep.


Pay bills or do a crossword between 10 and 11 AM or 8 and 9 PM
“According to our circadian rhythms, that's when we're maximally alert," says Michael Thorpy, MD, director of the Sleep-Wake Disorders Center at Montefiore Medical Center in the Bronx. Try not to waste a minute—the brain boost lasts only for about an hour.
