Welcome to your daily roundup of important health news
Every day, anestimated6,800 new peer-reviewed academic articles are published. That’s a whole lot of science to wade through—but don’t fret. We’ll do the legwork for you, each and every morning. H
ere’s your daily dose of the latest discoveries from journals, research institutions, and news outlets from around the world.
Bring On the Nuts
Snacking on walnuts may improve your sperm health, new research out of the University of Delaware suggests.
Researchers discovered that mice who consumed about 20 percent of their calories from walnuts a day—the human equivalent of roughly 2.5 ounces—had sperm that moved better and was shaped more normally than those who didn’t eat the nuts.
They believe that the nuts improve sperm quality by reducing oxidative damage in sperm cells. Longer-term studies in humans are necessary before any firm conclusions can be reached, though.
Check Those Smart Devices
When Amazon’s web services went out yesterday, it causes some surprising after-effects: Many smart devices went on the blink, leaving people unable to control them, the A.V. Club reports.
That includes household appliances like connected light bulbs and thermostats—and, even according to one tweet on the site, a smart oven that its user was unable to turn off.
Protect Your Lungs
People with lung diseases like asthma or chronic obstructive pulmonary disorder (COPD) might not be getting the benefits of treatment that they think: Many people who use inhalers make critical errors that impede their medication dosage, researchers from Rice University discovered.
Errors include not shaking the inhaler—or not shaking it long enough—placing it at the correct angle, breathing properly when inhaling, and not holding their breath for 10 seconds after inhalation.
As a result of these errors, a lot less medication than necessary is reaching patients’ lungs.
Test Your Heart Properly
Testing for a common heart condition may often yield inaccurate results, researchers from the University of Leicester discovered.
Exercising testing on people with aortic stenosis only has a 60 percent accuracy rate—and as result of the incorrect findings, many people undergo unnecessary open-heart surgery, the researchers say.
Avoid the Tanning Bed
You think a tan gives you a healthy glow, but it’s actually damaging your skin and putting your health in danger.
A new study in the Journal of Cancer Policy estimated that nearly 9,000 cases of melanoma, 86,000 cases of squamous cell carcinoma, and 168,000 cases of basal cell carcinoma could be attributed to tanning devices in 2015.
The cost for these cases? Over $343 million each year.
