The convenience, affordability, and flat-out fun of e-bikes and e-scooters are undeniable. But as their popularity grows, the rate of accidents involving e-bikes and e-scooters is climbing. So how do we minimize risks for accidents?
Kratom has been used for centuries for various conditions; today people are using it to treat chronic pain and mitigate opioid withdrawal symptoms. But there is no control or regulation of the product, and it can have serious side effects.
People reckoning with problem drinking choose different paths, including two well-known self-help organizations built around peer support: Alcoholics Anonymous and SMART Recovery. Researchers questioned people participating in these programs, or no program, about their approach.
Small animals like turtles, iguanas, and frogs are often chosen as first-time pets for children, but it may be best to avoid them because they can carry bacteria that can make people sick. Here’s what to know about this illness.
As global temperatures continue to soar, extreme heat poses numerous health risks, some of which are visible on our skin. Understanding how heat affects your skin can help you take measures to prevent or ease many skin conditions that are sparked or worsened by high temperatures.
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by lightheadedness or dizziness when standing and a racing heart. The underlying cause is not known, although it sometimes follows bedrest after injury or illness. Recently, POTS has been diagnosed in some people who have had COVID-19.
Most of us don’t think twice about standing up, but for people affected by postural orthostatic tachycardia syndrome (POTS), standing can provoke lightheadedness and a racing heartbeat. While some people with POTS will require medications, most will improve with some specific dietary and behavioral changes.
Climate change has made summers hotter, and the struggle to stay cool has led to more cases of heat-related illness. Don’t wait until you’re overheated to figure out how to cool down; use these ideas to get you started.
Just because you can get a particular test or treatment or take a supplement doesn’t mean you should. One study suggests as much as 20% of all health care in the US is unneeded. Skipping unnecessary care might actually improve your health, while saving time and money.
If you’re struggling with depression, the most important question about taking an antidepressant is whether it will work. But another question on your mind may be whether it will fuel weight gain. A new study provides some context.
I thought this myth had been debunked long ago. In fact, it has been well established that you cannot rely on the color or consistency of nasal discharge to distinguish viral from bacterial sinus infections, or even whether you’re dealing with an infection at all. Seasonal allergies are a good example. They can cause all sorts of nasal discharge — thick or thin, yellow, green, or clear — even though there’s no infection at all.
The US is seeing an unusual spike in the mosquito-borne illness dengue fever. What is dengue, and where is it occurring in the US? How does it spread? And what steps can you take to protect against this and other mosquito-borne illnesses?
The expression that something is “a hard pill to swallow” isn’t just a metaphor. Swallowing pills can be difficult and downright unpleasant. It causes one in three people to gag, vomit, or choke. That may keep people from sticking to their medication routines, which can make them sicker.
The 2016 summer Olympics had its share of exciting performances, upsets, and photo finishes. But for days after Michael Phelps’s first appearance at the games, it seemed all anyone could talk about was “cupping.” It’s an ancient therapy that left multiple circular discolorations on his skin. During “dry cupping,” suction is applied to the skin for several minutes; sometimes it is combined with massage, acupuncture, or other alternative therapies. (“Wet cupping” is similar except that blood is removed by making small cuts in the skin.)
Androgen deprivation therapy can slow or control prostate cancer, and adding a second class of drugs improves survival when the disease is in advanced stages. But all drugs that block testosterone have challenging side effects, and a review of studies showed that cardiovascular risks worsen when these drugs are given together.
Parenting can be challenging, but childhood and adolescence can be difficult too. How can parents help their kids manage anger, sadness, anxiety, and handle emotionally trying times? Practicing two skills can help both your child and you.
Hemorrhoids are painful and unpleasant, and difficult to talk about. But they are common among people over 50, and they are not dangerous and can be managed with simple remedies and self-care.
The number of adults in the US with at least one tattoo has risen dramatically in recent decades, so headlines about a study that found an association between having a tattoo and higher risk of lymphoma may have caused worry. But there’s much more to the story than just the headlines.
While alcohol remains the most-used drug in the US, daily cannabis use has outpaced daily drinking. In states where recreational cannabis is legal, a popular new item is cannabis-infused beverages. These products are different from edibles, and the timing and intensity of their effects on the body differ as well.
What’s so special about fish oil? It’s loaded with omega-3 fatty acids. These must come from food, since our bodies can’t make them.
Although less known and less understood than other types of dementia, Lewy body dementia is the second most common cause of neurodegenerative disease following Alzheimer’s. How do its symptoms differ, who is at risk, and how is it diagnosed and treated?
When you have a medical appointment, your health provider writes notes on the visit that are available to you. It’s a good idea to read these — though you may be surprised or confused by some of the language — and to check in if you have questions or need to make important corrections.
When you’re packing a hurricane go-bag, keep health priorities in mind. If you don’t prepare in advance, you might leave behind medicines, medical supplies, important paperwork, and other essentials that can help you stay healthy. Here’s how to plan ahead.
