Tiredness is often temporary, treatable or nothing to worry about, experts say that tiredness that suddenly worsens or prevents you from doing what you want can be a sign of a health problem or sleep disorder.

If you snore, there are health reasons to see a doctor about it

Discomfort is the first step toward developing work-related injuries, which caused about 2.8 million nonfatal, private-industry injuries and illnesses in 2017, according to the Bureau of Labor Statistics.

For most people, simply getting the flu vaccine - any flu vaccine - is what matters most, says David Cennimo, an infectious-disease specialist at Rutgers New Jersey Medical School in Newark.

Despite years of consistent messages from health-care providers about the dangers of the flu and the protective power (and safety) of the flu shot, many people still hold false beliefs about both.

Travelling through multiple time zones is often out of sync with our body's internal clocks which causes jet lag. Most common symptoms of jet lag can be nausea, disorientation, gastrointestinal distress and trouble concentrating.

Alysha Kellner was 23 weeks pregnant when she learned last year that her baby had a rare, fast-growing tumor on her heart that might require surgery while still inside the womb.

"Heart palpitations" is a catchall term used to describe anything unusual that people feel in the rhythms of their hearts.

You might feel them as skipped heartbeats or unusually forceful beats. One friend describes her heart palpitations as a soft fluttering that starts in her chest, moves to her neck and sometimes makes her cough. Another says her heart feels as if it's flipping over in her chest. Mine come in a "pause-thump" pattern that occasionally make me lighthea...

Exercising in the heat carries risks, including heatstroke and dehydration

Dozens of studies have shown that interval training can be beneficial for patients with Type 2 diabetes, heart disease and other chronic diseases. According to a 2007 study of 27 heart-failure patients who were mostly in their 70s and 80s, intervals were three times better than more-moderate exercise at improving aerobic capacity.

About 7 percent of kids between the ages of 3 and 18 have elevated blood pressure, also called hypertension or pre-hypertension.

Although osteoarthritis, often called OA, ordinarily shows up after age 65, it's not uncommon for younger people to show signs of wear in their cartilage.

Osteoarthritis may be growing more common, given that medical costs related to the condition have risen.

As costs decrease and discoveries accelerate, experts predict that 3-D printers will become routine tools for heart care, too. Optimistic scientists envision customized patches or even full-fledged beating hearts, ready to be implanted, an exact fit for the patient's body.
