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.

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.

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.

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.

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.

People can adapt the basic guidelines of the Mediterranean diet to any cuisine they like by choosing mostly plant-based foods and healthy fats. Latin America includes Mexico and more than 30 other countries in the Caribbean and Central and South America. Healthy choices include beans, corn tortillas, plantains, avocados and tropical fruits, as well as small amounts of fish, seafood, and queso blanco (a mild, white cheese).

The Watchman, a tiny, basket-like device placed in the heart’s left atrial appendage, is designed to prevent blood clots traveling from the heart to the brain and causing stroke. People with atrial fibrillation who face a high risk of bleeding from anti-clotting drugs may be good candidates for the device.

Maximum heart rate refers to the upper limit of what a person’s cardiovascular system can handle during exercise. It can be estimated by subtracting the person’s age from 220. Target heart rates (which range from 64% to 93% of the maximum) can help people know if they are doing moderate or vigorous exercise. Physical activity guidelines recommend that people get at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise, or a combination of both, per week.
