It’s hot out there, and if you’re spending time outside, sunburn shouldn’t be your only concern: it’s important to think about heart health during the heat and humidity, too.
Steamy weather can be dangerous for older individuals, people with heart disease and those taking certain medications for conditions such as high blood pressure and depression, experts say. It can even be a risk for otherwise healthy people if they don’t take some precautions. “Anybody, including athletes, can be vulnerable,” says Dr. Erin Michos, associate director of preventive cardiology and associate professor of medicine at the Ciccarone Center for the Prevention of Heart Disease at the Johns Hopkins University School of Medicine. “Take things slower in the heat. It doesn’t mean you’re less fit.”

High doses of vitamin D taken one hour after sunburn significantly reduce skin redness, swelling, and inflammation, according to double-blinded, placebo-controlled clinical trial out of Case Western Reserve University School of Medicine and University Hospitals Cleveland Medical Center. The trial results were recently published in the Journal of Investigative Dermatology.
In the study, 20 participants were randomized to receive a placebo pill or 50,000, 100,000, or 200,000 IU of vitamin D one hour after a small UV lamp “sunburn” on their inner arm. Researchers followed up with the participants 24, 48, 72 hours and 1 week after the experiment and collected skin biopsies for further testing. Participants who consumed the highest doses of vitamin D had long-lasting benefits — including less skin inflammation 48 hours after the burn. Participants with the highest blood levels of vitamin D also had less skin redness and a jump in gene activity related to skin barrier repair. Read more

What is a dehydration headache?
When some people don’t drink enough water, they get a headache or a migraine. There is little scientific research to support the notion of lack of water causing headaches. However, the lack of research doesn’t mean dehydration headache isn’t real. More likely, this just isn’t the type of research that gets a lot of funding. The medical community does have a formal classification for hangover headaches, which are partially caused by dehydration.
Keep reading to learn more about the symptoms of dehydration headaches, plus remedies and tips for prevention.

Just before Christmas a few years ago, Richard DiCarlo, MD, woke up in the night with burning pain on his left side. Turning on a light, he saw a row of red bumps and knew immediately that he had shingles, also known as zoster, caused by the reactivation of the chickenpox virus, dormant since a childhood infection.
After shingles and a year of postherpetic neuralgia, a painful condition that made it difficult to sleep, DiCarlo, an infectious disease specialist at Louisiana State University in New Orleans, counts himself among the supporters of the shingles vaccine. The shingles vaccine Zostavax was licensed in the U.S. in 2006. Data from the Shingles Prevention Trial, which enrolled 38,000 adults aged 60 and over, showed that men and women who got the shingles vaccine were half as likely to get the ailment after an average follow-up period of three years compared to those given a placebo shot. Vaccinated study participants who did develop shingles also had reduced pain compared to participants given a placebo shot. The vaccine was most effective in people ages 60-69 with increased decline in effectiveness associated with older age. Read more

Yellow jackets — properly known as Vespula, Dolichovespula, or Paravespula — are thin wasps with black and yellow coloring and long dark wings. Their stripes often cause them to be confused with honey bees, although bees tend to be rounder in appearance. Unlike bees, which create hives that produce honey, yellow jackets live in nests, which can be found in secluded areas or the ground.
Also unlike bees, which can only sting once since they inject their stinger into you, yellow jackets have the ability to sting you multiple times. When a yellow jacket stings you, it pierces your skin with its stinger and injects a poisonous venom that causes sudden pain. You may also experience inflammation or redness around the sting a few hours after being stung. Fatigue, itching, and warmth around the injection site are also common symptoms for many people.

Hear the word “microwave,” and you’re more likely to think of that miracle box in your kitchen than the radiation for which it’s named.
After all, microwaves heat your food through, well, microwaves. A form of electromagnetic radiation, microwaves have three characteristics that make them so darn good at zapping your leftovers, explains Dana Hunnes, adjunct assistant professor of community health sciences at the UCLA Fielding School of Public Health.
