Better together: The many benefits of walking with friends

Walking with others helps people stay accountable and stick to an exercise regimen, and motivates and challenges them to work harder.

The best sun-protective clothing

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.

How to recognize and respond to a “warning” stroke

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.
