16 Unexpected Ways to Add Years to Your Life


The average American’s life expectancy is 78.7 years. Whether you reach that age—or better yet, exceed it—largely depends on your genes, but there are also many keys to longevity that are totally within your control. Some you probably already know about, like following a nutritious diet, exercising often, staying away from cigarettes, and maintaining a healthy weight. Other habits are a little less obvious. Read on for some surprising habits and lifestyle choices that could add years to your life.

Adopt a furry friend

Your four-legged companion may be helping you live a longer life, according to a review published in the journal Circulation. Researchers believe owning a dog might keep the owner more active and, as a result, lowers the risk of heart disease.

“Dog owners are who walk their dogs are more likely to meet recommendations for daily physical activity (150 minutes weekly),” says Eric A. Goedereis, PhD, assistant professor of psychology at Webster University in St. Louis, MO. Owning a pet also reduces stress, which may decrease the risk of cardiovascular disease, he adds.

Have more sex

A roll in the hay may be the most pleasant way to extend your life. Several studies suggest there is a link between more orgasms and longevity. In a 1997 study, men who had more orgasms were less likely to die of heart disease than those who had less. While the study can’t prove cause and effect (maybe healthier people are more likely to have sex), sex can be beneficial for health. “Of course sex feels good, but it also gives us the opportunity to work out nearly every muscle in the body and connect with another person,” says Goedereis. “Sex has also been shown to boost the body’s immune response, reduce stress, and even control one’s appetite, among other things.” Two to three orgasms a week yields best benefits. Doctor’s orders.

Floss every day

Daily flossing not only gets rid of food trapped between your teeth but also removes the film of bacteria that forms before it has a chance to harden into plaque—something your toothbrush cannot do. Periodontal disease from lack of flossing can trigger low-grade inflammation, which increases the risk of early heart attack and stroke. Numerous studies link oral bacteria to cardiovascular disease. The American Dental Association recommends flossing at least once a day.

Have a positive attitude

Think being mean and ornery is what it takes to live to 100? That’s what scientists at the Albert Einstein School of Medicine in the Bronx, New York thought until they studied 243 centenarians. When the researchers assessed their personalities, they discovered that most had a positive outlook on life, and were generally easygoing, optimistic, and full of laughter.

If nothing else, try to laugh more often—go to comedy shows, take occasional breaks at work to watch silly videos on YouTube, or spend time with people who make you smile. “Laughter helps decrease blood pressure, reduce blood sugars, dull pain, and lower stress, all of which can make your body healthier,” says Elizabeth Lombardo, PhD, psychologist and author of Better than Perfect: 7 Strategies to Crush Your Inner Critic and Create a Life You Love.

Be social

Going to the movies or out for coffee with friends may help all of you grow old together. An analysis by Brigham Young University looked at data from 148 studies and found a clear connection between social ties and lifespan. “People with stronger social relationships have a 50% greater chance of continued living as compared to those with weaker relationships,” says Lombardo. “Loneliness can also compromise your immune system, making it harder to fight off disease.”

Go nuts

Snack on cashews, sprinkle chopped walnuts on your salad, stir almonds into your yogurt—however you eat them, it may be helpful. People who ate nuts several times a week had a reduced mortality risk compared with those who ate nuts less frequently (or at all), according to a 2013 New England Journal of Medicine study.

Nuts are high in antioxidants, fiber, and unsaturated fatty acids, and they help lower your risk of heart disease. “They are known to possibly improve certain risk factors for diabetes as well,” says Keri Gans, RD, a New York-based nutrition consultant. As a healthy but high-calorie snack, limit portion sizes to 1 ounce, or about 20 nuts.

Find your purpose

Regardless of your age, finding purpose in life may help you live long enough to make a difference. In a study of 6,000 people, researchers at the University of Rochester Medical Center in Rochester, New York found that people who had a greater sense of purpose were less likely to die during the 14-year study than those who were less focused on a goal. “People who have a sense of purpose in their lives may be more likely to take steps to be healthier,” says Lombardo. To develop a sense of purpose, focus on the positive impact you are making at work or at home instead of getting caught up with every little detail being perfect, she suggests.

Start your mornings with coffee

Sipping a mug of coffee not only jumpstarts your day, but your longevity as well. Studies show coffee reduces the risk of a number of chronic diseases. “Drinking coffee may decrease your risk for diabetes, cardiovascular disease, and Alzheimer’s disease,” says Gans. Just go easy: too much caffeine can trigger anxiety and insomnia, or interfere with calcium absorption. And hold the whipped toppings like syrups and cream to avoid canceling out the health benefits.

Snooze soundly

Quality of sleep also plays in role in how long you may live. Multiple studies have linked sleep deprivation with an increased risk of death, and other research has shown that a lack of shuteye may raise risk of type 2 diabetes. “Some people may need more or less sleep than others, but research suggests that seven hours is probably enough,” says Goedereis. To sleep soundly, establish a nighttime routine and stick to a schedule, even on weekends.

See the glass as half full

An Illinois study found clear evidence that happy people experience better health and live longer than their unhappy peers. “Depression, pessimism, and stress predict shorter lifespans,” says Lombardo. “These mental states tend to cause a stress reaction within the body, which can weaken the immune system. Happiness, on the other hand, tends to result in less stress hormones.” Take time to experience gratitude every day. “It’s one of the quickest and longest-lasting ways to boost happiness,” she adds.

Ditch soda

Even if you’re not overweight, drinking soda may be shortening your lifespan, according to a study in the American Journal of Public Health. The five-year study found a link between soda intake and shortening of the telomeres, which are caps on the ends of chromosomes directly linked to aging. Telomeres shorten each time a cell divides and are thought to be an aging “clock.” This study did not find the same link with diet soda, but other research has associated heavy diet soda drinking to weight gain, type 2 diabetes, and depression—all potential life-shorteners.

Have a little bit of wine every day

Drinking a little less than one glass of wine a day is linked to a lower rate of cardiovascular death from all causes when compared to abstaining from all alcohol, according to a Dutch study. Researchers found that light alcohol consumption resulted in longer life expectancy at age 50. Drinking less than or equal to 20 grams per day of alcohol (that’s a little less than a serving of beer, wine, or spirits) was associated with a 36% lower risk of all causes of death and a 34% lower risk of cardiovascular death. And sorry, beer and cocktail fans: the same results were not found with light-to-moderate alcohol intake of other types.

Run 5 minutes a day

No need to run for an hour a day to reap the life-lengthening benefits. A new study shows running just 5 to 10 minutes a day increases your life expectancy by reducing the risk of death from heart disease by 58% and dropping the overall risk of death by 28%. It holds true even if you’re a slowpoke. Those who ran at less than 6 miles per hour only once or twice a week experienced clear benefits, the researchers reported in the Journal of the American College of Cardiology. Researchers credit better lung and heart function with the extended lifespan. Consistency works best, however: Exercisers who ran regularly for an average of six years reaped the greatest benefits.

Eat lots of fish

A diet heavy in omega-3-rich foods may add years to your life, says a study from the Annals of Internal Medicine. In the study of more than 2,600 adults, those with the highest blood levels of omega-3 fatty acids—found in salmon, albacore tuna, mackerel, and lake trout—lived more than two years longer on average than those with lower blood levels. The study didn’t prove that being a fish-eater increases longevity, but suggests a connection. Researchers found that people with high omega-3 levels reduced their overall risk of death by any cause by up to 27% compared to those with the lowest levels, and that they had a 35% lower risk of dying from heart disease. Experts recommend at least two 3.5-ounce servings of fish a week.

Stop sitting so much

Simply stand up more during the day and you’ll boost your longevity by increasing the length of your telomeres, according to a study from the British Journal of Sports Medicine. The study measured the effects of sitting time and physical activity among 49 sedentary, overweight participants. Researchers found increased telomere length—end caps of chromosomes that link directly to longevity—in the red blood cells of individuals participating in a 6-month physical activity intervention.

Volunteer

Helping others not only feels good, it may help you live longer, too. A review of data from 40 published papers found a 20% lower risk of death than non-volunteers. The findings, published in the journal BMC Public Health, found that those who volunteered experienced lower levels of depression, better life satisfaction, and overall enhanced wellbeing. Another study found that retirees who volunteered at least 200 hours in the prior year were less likely to develop high blood pressure than non-volunteers, lowering their risk of heart disease. Lend a hand for a win-win result.

5 Surprising Ways You're Destroying Your Teeth


Protect your pearly whites from these unexpected dental wreckers

When it comes to cavities, there are the usual suspects to blame: soda, sugar, shoddy brushing. But other chomper wreckers may fill your daily routine, too. Keep reading for 5 unexpected dental culprits—and the best ways to stop them.

Cardio

Long cardio workouts may take a toll on your pearly whites, a new German study found. The researchers compared the oral health of endurance athletes with non-exercisers and found that the athletes were more likely to have tooth erosion, which is a gradual wearing away of enamel. And the more time they spent training per week, the greater their risk of cavities.

That's because exercise reduces your saliva, the researchers found. Saliva is filled with minerals that nurture your teeth and neutralize acids that cause wear and rot. On top of that, consuming sugary energy gels and acidic sports drinks during training can encourage tooth decay, says Men's Health dentistry advisor Mark S. Wolff, D.D.S., Ph.D.

Your fix: Since you have less saliva during long training sessions, battle decay-causing bacteria and plaque by brushing before you exercise and rinsing your mouth with water after consuming anything sugary or acidic, Wolff says. Plus, chewing sugar-free gum when you work out can boost your saliva production, says study author Cornelia Frese, D.D.S., a senior dentist at University Hospital Heidelberg in Germany. 

Weight Lifting

It's a natural tendency to clench your jaw when you strain to lift weights, Wolff says. It may even improve performance by increasing blood flow to parts of your brain associated with motor control, recent research finds. But all that pressure can wear down your teeth or even crack them, causing persistent pain in your jaw, he says.

Your fix: If you bite down hard when you exert yourself in the gym, consider wearing a mouthguard, Wolff says. Inexpensive "boil-and-bite" mouth guards are effective and easy to find at drugstores or sporting goods stores, he says.  Or your dentist can make you a custom one, which will fit better, he says.

 

Medications

Hundreds of medications for allergies, depression, heart health, and blood pressure cause dry mouth. That may not sound like a major side effect, but it can wreak havoc on your teeth, since they need saliva to protect against acids that cause decay and erosion, says Edmond Hewlett, D.D.S., an American Dental Association advisor and professor at the University of California Los Angeles School of Dentistry.

"When you don't have an adequate saliva supply, your teeth can undergo catastrophic damage in a matter of months,” he says.  

Your fix: Chewing on sugar-free gum and sucking on sugar-free hard candy throughout the day will help stimulate saliva production, Hewlett says. Stay away from sugary and acidic foods that encourage decay and erosion, he says. Eating that stuff will exacerbate the problem.

Heartburn

Sure, the chest pain sucks, but did you know that acid reflux can do permanent damage to your teeth, too? The acid from your digestive system can wind up in your mouth, dissolving your enamel just like the acid from soda or sports drinks. This acid, however, can be even more potent, Hewlett says. 

Your fix: If your dentist finds erosion on the teeth located at the back of your mouth, acid reflux is most likely the culprit, Hewlett says. Ask your physician how to tackle your heartburn, Hewlett says. A prescription medication may be the best solution

Meal-Time Brushing

Brushing after eating acidic foods—like juice, fruit, sports drinks, red wine, and soda—can weaken enamel, Wolff says. That may lead to yellowing and greater odds of cracks and chips.  

Your fix: Swish with water to rinse away the acid and wait 40 minutes for the calcium in your saliva to remineralize weakened areas. Then brush.
