The Real Reason Your Hands Are Always Cold

If, in general, you feel like your hands are somehow always inside their own personal ice buckets, you’re not alone. It turns out that having perpetually cold hands is a pretty common complaint. And, luckily, it’s probably not something you need to worry too much about. But it is annoying. Essentially, your hands are kept warm thanks to your body’s circulatory system. Warm blood is sent all the way from your heart down to your fingers, and more blood means more warmth. But if…

Ears Ringing From a Loud Concert? Why That’s Not a Good Sign

When you come out of a loud concert or sporting event with ringing ears, you likely wait for the sensation to fade and then forget about it. Maybe your ears get a workout from all the racket, but they seem to recover, right? The truth is, that feeling in your ears is telling you something: You already have damaged your hearing. No matter how old you are, you need to protect your ears around loud noises to avoid premature hearing loss. Hearing loss: Understanding the stakes Ringing or dullness in your ears after exposure to loud sounds are signs you have overworked your…

Why You Feel Sick After Taking Vitamins

A daily multivitamin or supplement may give your well-being an extra boost, but if you’ve ever swallowed one and felt sick right after, you know it’s hardly a pleasant experience. It can even make you want to ditch the regimen altogether. Taking certain types of vitamins may cause a range of gastrointestinal issues, according to Dr. David Poppers, a gastroenterologist at New York University’s Langone Medical Center. It isn’t unheard-of to experience abdominal pain or discomfort, queasiness or diarrhea.

Study Gets to the Core of Back Pain in Runners

The onset of back pain among runners may stem from a general weakness in their deep core muscles, new research indicates. Such deep muscles are located well below the more superficial muscles typified by the classic six-pack abs of fitness magazine fame, the researchers noted. Using computer simulations, they found that runners with relatively weak deep core muscles end up relying more and more on their superficial muscles to keep on running. The result is a higher risk for back pain. “We measured the dimensions of runners’ bodies and how they moved to create a computer model that’s specific to that person,” said study lead author Ajit Chaudhari. “That…

Good Carb, Bad Carb: 4 Myths Debunked

When you’re focused on losing or maintaining weight, you get plenty of advice about carbs. What’s the truth — should you avoid carbs at all costs, or just certain ones? Our dietitians reveal the facts behind common carbohydrate myths: Myth 1: Carbs make you gain weight “People often say that carbs are fattening. But complex carbohydrates, like whole grains, are not ‘fattening’ foods,” says Kristin Kirkpatrick, MS, RD, LD. This myth, she believes, may spring from carbs’ effect on insulin. Eating carbohydrates raises your blood glucose and prompts your body to release insulin. This redirects your glucose to cells. “But it’s the type and quantity of the…

7 Ways to Stay Social in the Dead of Winter

Being social is an essential part of life. Humans are social creatures with an emotional need for relationships and connections with others. Our social connections not only give us happiness, but they can also influence our mental and physical wellbeing. Meaningful relationships can act as a psychological buffer against stress, and people who have them have been shown to be happier, have fewer health issues, and even live longer lives. By contrast, there is evidence that being socially isolated can lead to depression, illness, or a reduced lifespan. Yikes! Although staying socially active and maintaining relationships is an important part of life, it…

The Secret to Making Post-Run Back Pain a Thing of the Past

Does chronic back pain get in the way of your otherwise cathartic, concert-worthy runs? According to a new study, one simple tweak to your fitness routine could stop that achy buzzkill in its tracks (so you can keep going, full speed ahead). Research published in the Journal of Biomechanics examined the primary causes of chronic low back pain in runners, and it all comes down to the strength of your midsection. People with weaker core muscles have a higher risk of developing back pain, the authors wrote, because the superficial ab muscles are doing the hard work that the deep core muscles should be doing, causing faster fatigue and, ultimately, pain. “When your deep…

4 Best Foods for Your Bones (and the 4 Worst!)

What are the best foods for bone health? What are the worst? The answers might surprise you! If you turned on the TV or opened a magazine between 1994 and 1014, you likely saw the Got Milk? ads that touted three glasses a day for bone health.

Sure, milk is high in calcium, but there are actually a number of nutrients that come into play when we’re talking bone health. I get into the details a little bit more here, but magnesium is actually…
