Going for a brisk walk with one or more friends has many health benefits. It’s a form of socializing, which is good for thinking skills and helps stave off loneliness, isolation, and many chronic diseases. Walking with others helps people stay accountable and stick to an exercise regimen, and motivates and challenges them to work harder. Plus, it’s safer to walk with buddies, who can all watch for hazards and call for help in an emergency.

A 2022 study suggests that sleep irregularity—night-to-night variations in sleep duration and timing (when someone falls sleep)—are linked to atherosclerosis (plaque buildup in the arteries).

Sun-protective clothes are made of materials that shield your skin from harmful ultraviolet (UV) rays. The most effective fabrics for the job have high thread counts, are tightly woven, and are dark or bright colors (which absorb light). Examples include polyester, nylon, lightweight wool, or canvas. Many clothing manufacturers now use high-tech fabrics for sun-protective garments. Some wick away moisture and dry quickly. Some are embedded with chemicals used in sunscreens (such as zinc oxide and titanium dioxide). High-tech fabrics offer at least as much protection as regular densely woven fabrics, and maybe more.

For many people, attacks of vertigo recur periodically. The attacks are usually caused by a disorder of the balance (vestibular) system. Examples of balance disorders include benign paroxysmal positional vertigo (BPPV), cervical vertigo, Meniere’s disease, and vestibular migraine. Treatment for recurring vertigo involves getting the underlying cause under control; seeking physical therapy tailored to people with balance disorders; and (for people with BPPV) doing a particular maneuver to reposition loose debris in the ear canal.

A 2022 study found that yoga may offer some protection against frailty. Participants who practiced yoga improved two markers of frailty—walking speed and the ability to get up from a chair—compared with people who didn’t practice yoga.

Blood pressure measurements taken at a doctor’s office can vary widely from one visit to the next, according to a 2022 study. It included blood pressure measurements from almost 537,000 people, each with an average of 13 doctor visits over two years.

A transient ischemic attack (TIA) can cause a range of unsettling symptoms, including slurred speech or arm weakness. The symptoms appear suddenly but usually last less than five minutes, which is why TIAs are often ignored or missed. However, two of every five people with a suspected TIA who get an appropriate brain imaging test find out that they actually had a stroke. Recognizing the symptoms and seeing emergency care right away is vital. The mnemonic BE-FAST (which stands for balance, eyes, face, arms, speech, and time) was designed to help people identify the symptoms of a TIA or stroke and to act quickly.

Although golf is a low-to-moderate intensity exercise, the game can last up to four hours and players may walk up to six miles. A 2023 study found that walking a round of 18 holes may be slightly better for cardiovascular health than an hour of brisk walking or Nordic walking. Golf provides a sense of competition and camaraderie and can be played well into older age, unlike more strenuous sports such as basketball or soccer. Even if people are not physically able to walk the entire course, hitting the ball works the muscles of the core and arms, and the golf swing provides a balance challenge.

Unlike a few decades ago, there are now a number of minimally invasive ways to treat varicose veins. Doctors can shut down problem veins with injections of various substances or certain catheter procedures. A treatment currently in clinical trials in the United States promises to simply “zap” away varicose veins from outside the body. Called high-intensity focused ultrasound, it converts sound waves into a focused beam of heat that seals a malfunctioning vein.

When physical change makes once easy tasks challenging, it may be time to turn to certain therapists for help. A physical therapist can use exercises to help someone improve strength, balance, and mobility. An occupational therapist can teach someone new ways to do daily tasks by adjusting existing techniques or using adaptive equipment. A speech-language pathologist guides a person through exercises that help with difficulties speaking loudly, swallowing, or communicating.
