Deep breathing helps your body unwind. Sit comfortably, breathe in for four seconds, hold for seven, and exhale slowly for eight. Long exhalations activate the vagus nerve, calming your heart and easing stress. Try it for 15–20 minutes a day.
A huge study of 473,000 adults found that watching 4+ hours of TV a day is linked to higher risks of dementia, depression, and Parkinson’s. It can’t prove TV is the cause, but it’s one more reason to switch off and get moving.
A study finds air pollution is linked to reduced cognitive ability. You can’t control outdoor air, but you can improve what you breathe: keep smoking out of the house, avoid busy roads when exercising, close windows on bad-air days, and choose walking, biking, or transit when you can.
ADHD is often misunderstood and surrounded by stigma. Learn what ADHD looks like in adults, common myths, and ways to help manage symptoms and improve daily life.
Ellipticals are stationary exercise machines that simulate walking, running, or stair climbing. They combine cardio with strength training and can simultaneously engage the upper and lower body for a full-body workout. Ellipticals also offer a low-impact exercise, placing less stress on the knee, hip, and ankle joints, which make them ideal for people who have knee or hip osteoarthritis or are recovering from an injury.
There are many ways people can meet the national guidelines for weekly activity. While running and walking are popular exercise choices, they are not the only options. Many sports and activities provide a similar heart-pumping workout, such as boxing, swimming, cycling, basketball, dancing, and even pickleball. People can also get creative and do circuit training using gym machines or perform cardio exercises at home.
The gut microbiota contains trillions of microbes, including both good and bad bacteria. Good bacteria help digest food and absorb nutrients, regulate appetite, synthesize vitamins, and support the immune system. When the gut microbiota becomes unbalanced because of an increasing number of bad bacteria, problems can arise. Keeping the gut balanced and healthy involves eating more probiotics (foods containing good bacteria) and prebiotics (foods that help existing good bacteria grow).
Bowel preparation (prep) is considered the most unpleasant part of the colonoscopy process, but it’s also crucial. A clean bowel helps the gastroenterologist more easily locate and remove polyps, small growths that can develop into cancer. If the prep is inadequate, the patient will have to repeat the process. Updated guidelines for gastroenterologists, published in 2025, can help them guide their patients to have more successful preps.
Daily nasal irrigation (also called nasal rinses) may reduce symptom severity and the duration of a cold. It can also relieve the congestion caused by sinus infections and allergies. It is unclear whether it can prevent colds. By means of a squeeze bottle, neti pot, or battery-powered system, saline (salt water) is inserted into one nostril and flows out the other. It’s important to always use sterile water, meaning distilled or cooled boiled water. The rinse helps wash away mucus and some inflammatory chemicals, reducing the swelling that’s responsible for congestion.
Total knee and hip replacements are highly successful procedures that can relieve pain and restore mobility for people with severe arthritis. Occasionally, joint replacement fails, and revision surgery is needed. Reasons for revision include infection, implant loosening, dislocation, and fracture. Warning signs of a problem include persistent pain, swelling, or instability. Revision surgeries are more complex, require longer recovery, and carry higher risks than the original surgery. Experienced surgeons who perform these procedures frequently tend to have the most success.
