Many people don’t take their medications exactly as prescribed. While some do this purposefully, plenty more simply forget. Researchers have studied several different methods to help people remember their medication, but a new study has revealed one that stands out among the rest: texting. While the study does have some limitations, it’s an impressive reminder that the technology sitting in many people’s pockets and purses can be a powerful tool to help them improve their health.
Stories about medical research are often presented in a manner that makes the findings seem more significant than they really are. It is important to approach such stories with a degree of skepticism, and appropriately tempered expectations.
The benefits of regular exercise are well understood, but some forms of exercise carry a higher risk of injury than others. A new study of female runners suggests that an individual’s running style may play a role in susceptibility to injury, but it also raises questions about technique that warrant further study.
The body mass index (BMI) has long been considered an important way to gauge your risk for many chronic conditions, from arthritis to sleep apnea to heart disease. But like all medical measures, BMI is not perfect — and a recent study has revealed that BMI alone may not be a solid measure of cardiovascular health. Here, we’ve examined the pros and cons of the BMI, and whether it’s a number worth knowing.
Being able to react to a fall — throwing out a hand, grabbing a railing — often makes the fall less serious. But our reaction times slow as we age, making this kind of quick adjustment much harder as we get older. We’ve examined some of the biological reasons why falling becomes more serious as we age and some ways to make falling less likely — including the possibility of improving slowed reaction times.
Much has been promised about the potential health benefits of vitamin D, but the evidence behind many of these promises is lacking. In fact, a recent study that tested whether vitamin D supplements protected older people from physical decline found that those on higher doses were more likely to have a fall. It’s important to get enough vitamin D in your diet. But when it comes to supplements, more is not always better.
Although it may sound alarming, the statistics don’t lie: on average, men are likely to die at earlier ages than women. There are a number of factors that might explain this; some of them can’t be changed, but others can. Regardless of the reasons, the best thing men can do to enjoy a long life is to proactively protect their health, with their doctor’s help.
A recently published study has found that the incidence of kidney stones is on the rise. These stones, which are formed when chemicals in the urine crystallize, can cause serious complications in addition to the usual pain and urinary trouble. It’s not clear why they’re becoming more common, but climate change and rising rates of obesity may be to blame.
Many people still think the color or consistency of nasal discharge determines whether you have a sinus infection. The truth is that anything that irritates the nose’s delicate lining — whether a virus, bacterium, or allergen — can result in any color or consistency of discharge. In fact, viruses are the most common cause of sinus infections, meaning you shouldn’t run to your doctor based on your mucus color alone.
About 1 in 3 people report at least one episode of fainting during their lifetime, so it’s surprising that we don’t see people fainting more often. Fainting is usually harmless, the body’s response to emotional or physical stress. But in some cases, fainting can indicate an underlying problem such as heart abnormalities or seizures. And even when the cause of fainting is not that serious, fainting that leads to a fall can cause injury.
