You’re the life of the party
Outgoing people are 50 percent less likely to develop dementia, according to a recent study of more than 500 men and women age 78 and older from the Karolinska Institutet in Sweden. Participants also described themselves as not easily stressed.
Researchers speculate that their more resilient brains may be due to lower levels of cortisol — studies show that oversecretion of this “stress hormone” can inhibit brain cells’ communication. Science-backed ways to cut cortisol levels: Meditate, sip black tea, or take a nap.
You run for 40 minutes a day
Scientists in California found that middle-aged people who did just that — for a total of about 5 hours per week — lived longer and functioned better physically and cognitively as they got older; the researchers tracked runners and nonrunners for 21 years. “What surprised us is that the runners didn’t just get less heart disease — they also developed fewer cases of cancer, neurologic diseases, and infections,” says study author Eliza Chakravarty, MD, an assistant professor of medicine at Stanford University School of Medicine. “Aerobic exercise keeps the immune system young.” If you don’t like to run, even 20 minutes a day of any activity that leaves you breathless can boost your health, she says.
You like raspberries in your oatmeal
Most Americans eat 14 to 17 g of fiber per day; add just 10 g and reduce your risk of dying from heart disease by 17 percent, according to a Netherlands study. Dietary fiber helps reduce total and LDL (“bad”) cholesterol, improve insulin sensitivity, and boost weight loss. One easy fix: Top your oatmeal (½ cup dry has 4 g fiber) with 1 cup of raspberries (8 g) and you get 12 g of fiber in just one meal.
You feel 13 years younger than you are
That’s what older people in good health said in a recent survey of more than 500 men and women age 70 and older. “Feeling youthful is linked to better health and a longer life,” says researcher Jacqui Smith, PhD, professor of psychology at the University of Michigan. “It can improve optimism and motivation to overcome challenges, which helps reduce stress and boost your immune system and ultimately lowers your risk of disease.”
You started menopause after age 52
Studies show that naturally experiencing it later can mean an increased life span. One reason: “Women who go through menopause late have a much lower risk of heart disease,” says Mary Jane Minkin, MD, clinical professor of obstetrics and gynecology at Yale University School of Medicine.
You had a baby later in life
If you got pregnant naturally after age 44, you’re about 15 percent less likely to die during any year after age 50 than your friends who had their babies before age 40, reports a recent University of Utah study. “If your ovaries are healthy and you are capable of having children at that age, that’s a marker that you have genes operating that will help you live longer,” says lead researcher Ken R. Smith, PhD, professor of human development at the university.
You don’t snore
Snoring is a major sign of obstructive sleep apnea, a disorder that causes you to stop breathing briefly because throat tissue collapses and blocks your airway. In severe cases, this can happen 60 to 70 times per hour. Sleep apnea can cause high blood pressure, memory problems, weight gain, and depression. An 18-year study found that people without OSA were 3 times more likely to live longer than those with severe apnea. If you snore and have excessive daytime drowsiness or mood changes, talk with your doctor about a referral to a sleep center.
