Could Tennis Be One Secret to a Longer, Healthier Life?

Scientists love telling us what needs to be done to achieve longer, healthier lives. We know that exercise is good for heart health—ideally 45-minute sessions, three to five times per week—and some research suggests that team sports improve mental health.

As The New York Times reports, another new study is highlighting the surprising health benefits associated with certain sports in particular. Researchers say tennis is linked to a 9.7-year increase in life span, compared to 6.2 years for badminton, five years for soccer, 3.7 years for cycling, and 3.2 years for running.

These findings, published in the journal Mayo Clinic Proceedings, are based on analyses of the lifestyle choices and exercise habits of 8600 Danish people who participated in health exams and lengthy questionnaires over the course of about 25 years. Some of the participants died during that time, and researchers compared their life spans with the type of exercise they did and how often they did it. Unsurprisingly, while the study showed no causation, all sports were associated with a longer life when compared with people who led sedentary lives. The breakdown of those sports, and how good they are for your health, is where it starts to get interesting.

Even when the researchers controlled for different factors such as education, socioeconomic status, and age, tennis still came out on top as the best sport for longevity. These findings seem to support those of a 2017 study of more than 80,000 British people, which found that players of racket sports tended to liver longer than joggers.

Dr. James O’Keefe, a co-author of the new study, told the Times it’s not clear why some sports are correlated with increased longevity more than others. However, he theorized that the social aspect of certain sports plays a critical role. “We know from other research that social support provides stress mitigation,” he says. "So being with other people, playing and interacting with them, as you do when you play games that require a partner or a team, probably has unique psychological and physiological effects.”

5 Holiday Foods That Are Dangerous to Pets

One of the best parts of the holiday season is the menu of indulgent food and drinks that comes along with it. But while you enjoy that cup of spiked hot cocoa, you’ve got to be careful your dog or cat doesn’t nab a lick. Here are five holiday treats that are dangerous for your pets, according to Vetstreet.

1. COFFEE

Any coffee lover will agree that there’s nothing quite like an after-dinner cup of joe on a cold night. But pups, kitties, and other pets will have to sit this tradition out. Caffeine can prompt seizures and abnormal heart rhythms in pets, and can sometimes be fatal. Other caffeinated drinks, such as soda or tea, should also be kept away from your four-legged family members.

2. BREAD DOUGH

We know the threat that bread dough poses to the appearance of our thighs, but it’s much more dangerous to our furry little friends. Holiday bakers have to be careful of unbaked bread dough as it can expand in animal stomachs if ingested. In some dogs, the stomach can twist and cut off the blood supply, in which case the pup would need emergency surgery.

3. CHOCOLATE

A little chocolate never hurt anybody, right? Wrong. The sweet treat can cause seizures and even be fatal to our pets. Darker chocolate, such as the baker’s chocolate we love to put in our holiday cookies, is more toxic to our pets than milk or white chocolate. The toxic ingredients include caffeine and theobromine, a chemical found in the cacao plant.

4. MACADAMIA NUTS

Macadamia nuts, which are a common ingredient in holiday cookies and often put out to munch on as an appetizer, can be toxic to dogs. While poisoning might not always be easy to detect in a pet, clinical warning signs include depression, weakness, vomiting, tremors, joint stiffness, and lack of coordination.

5. ALCOHOL

Think back to when you first started drinking and how much less alcohol it took to get you tipsy, because you likely weighed less than you do now. Well, your pet probably weighs a lot less than you did, even back then, meaning it takes much less alcohol to make them dangerously sick. Keep those wine glasses far out of reach of your pets in order to avoid any issues. Well, maybe not any issue: We can’t promise that this will stop you from getting embarrassingly drunk at a holiday party this year.

L’Oréal’s New Wearable Sensor Keeps Track of Your Daily UV Exposure

Anyone who has ever suffered a sunburn knows that too much exposure to UV radiation is bad for your skin. But in the moment, it can be hard to tell when you’ve gotten too much sun—especially during the winter, when you might not think you need sunscreen. (In reality, snow reflects up to 80 percent of the sun’s UV light, so you may end up getting hit with the same rays twice.) A new wearable sensor spotted by Wired aims to make understanding your sun exposure a whole lot easier.

L'Oréal’s new La Roche-Posay My Skin Track UV sensor pairs with a smartphone app to alert users when they’ve had high levels of UV exposure. Developed by L'Oréal’s Tech Incubator in collaboration with Northwestern University engineering professor John Rogers and Swiss designer Yves Béhar, the sensor measures UVA rays (which are associated with skin aging and skin cancer) and uses an algorithm to calculate UVB exposure (which is associated with sunburn and skin cancer).

At only half an inch tall and 1.3 inches long, the waterproof sensor is designed to be discreetly attached to your clothes, watchband, or sunglasses. The sensor's LED detector measures UV rays as sunlight passes through a small window in the device, then transfers the data to your phone via a near-field communication (the same technology in some hotel key cards). It stores the photons from the UV rays in a capacitor, eliminating the need for a battery.

Based on this data, the My Skin Track app can tell you how close you're getting to the maximum limit of UV exposure doctors recommend per day. It also provides updates about the air quality, pollen count, and humidity wherever you are at any given moment. Based on this information, as well as data about your specific skin type and skin tone, the app's Skin Advice feature will provide customized tips for keeping your skin healthy. It also recommends specific products—La Roche-Posay items can be bought directly through the app, should you desire.

The sensors are exclusively available through Apple stores. You can order one online for $59.95.
