A 2024 Harvard study involving more than 84,000 diabetes-free people (average age 62), who were followed for seven years, found those whose sleep duration varied most had a 34% higher risk for diabetes, compared with those whose sleep duration varied the least.

Even if someone has never gotten the flu or COVID-or at least hasn't gotten very sick from them-there still are good reasons to get vaccines that protect against the viruses. Both the flu and COVID viruses can injure the body, making it vulnerable to new major illnesses such as heart, lung, gastrointestinal, or brain disease. But recent solid evidence has shown that vaccines not only reduce the risk of getting the flu and COVID, but also reduce the risk of developing the serious diseases associated with COVID or flu.

Bouts of dizziness can be unsettling sensations that may last only a few seconds or linger for several minutes or even longer. Episodes may be isolated or recurrent. Many people have a difficult time articulating what they experience when they say they feel dizzy, because the term encompasses a range of sensations like lightheadedness, wooziness, unsteadiness, or spinning. To help identify the cause, people should first consider whether they are experiencing primarily lightheadedness or vertigo.

In 2022, the largest known outbreak spread to nearly 100,000 people in more than 100 countries. Now, a new outbreak of mpox has put it back in the news. What should you know - and do - about this latest international health emergency?

A 2024 study of more than 215,000 people (ages 37 to 73) found a link between consuming a sodium-rich diet and increased risks of having eczema, an eczema flare-up, or severe eczema.

People with anemia have an abnormally low number of red blood cells. Those are the cells that pick up oxygen from the lungs, deliver oxygen throughout the body, and return to the lungs with a load of carbon dioxide and other gases to be exhaled. Without enough red blood cells, the organs and tissues don't get a sufficient amount of oxygen. That can cause nonspecific symptoms, such as fatigue, headache, or wooziness, which are often attributed to other causes. As a result, anemia often goes undiagnosed.

A growing number of people ages 60 and older suffer from knee osteoarthritis. If lifestyle strategies, such as weight loss, physical therapy, exercise, and oral or topical medications don't offer sufficient pain relief, people may benefit from either corticosteroid or hyaluronic acid injections. Injections can provide immediate pain relief, reduce inflammation, and increase mobility. However, they are a temporary treatment that won't cure knee osteoarthritis or change the course of the disease.

Heartburn usually goes away on its own, but sometimes medication is needed to provide relief. For occasional heartburn, people can use over-the-counter antacids that are magnesium-based, aluminum-based, or calcium-based. If heartburn strikes several times a week or symptoms become more severe, a nonprescription H2 blocker can help. Individuals with persistent heartburn may have gastroesophageal reflux disease (GERD) and will probably need a proton-pump inhibitor. These are available in over-the-counter and prescription versions.

A variety of factors can make food taste overly salty. These include seasonal or food allergies, medication side effects, gastroesophageal reflux disease (GERD), diabetes, autoimmune conditions, or a chronically dry mouth. People should discuss the problem with their doctor.
