Water sports that use oars or paddles are effective forms of exercise with many health benefits. However, the sports may pose health risks, especially after age 60. The sports have a repetitive component to them. Paddling can stress the shoulder tendons. Rowing can lead to low back strains. Neither sport would be a good idea for people with tendinitis at the shoulder, elbow, or wrist; a diagnosed back problem such as a disc injury or spinal stenosis; or a previous back surgery.

Two important types of fat in the body are white fat and brown fat. White fat is located in the chest, abdomen, and upper legs; too much of it constitutes obesity. Its function is to provide insulation against the cold, store fats derived from food, and continually release small amounts of the fats to be converted into energy. Brown fat is found in small amounts in the neck, shoulders, chest, and abdomen. Its main function is to burn the fat it stores, creating heat that keeps the body warm.

Physical activity monitors, such as smart watches and fitness trackers, may help people get more exercise, such as extra daily steps and more moderate-to-vigorous activity per week. But the long-term durability of this behavior change is unknown. Using a fitness tracker requires more than just moving more; people also have to remember to keep the tracker charged, wear it consistently, and check their data. But for some people, the day-to-day feedback on their progress may help keep them engaged.

Processed foods are those that have been changed from their original form. A minimal level of processing may mean the food has simply been chopped and frozen or that inedible parts have been removed. At the next level, processed foods have a few added ingredients. Foods with even more processing are called "ultra-processed" foods. Ultra-processing usually means that the original foods are not recognizable, and include additives such as preservatives, oil, sugar, salt, coloring, and flavoring. If there are more than a few ingredients listed on a food label, that food is probably ultra-processed, which is bad for health.

People can get sunburned even with sunscreen on, particularly if they use old sunscreen or certain drugs and skin care products that leave skin vulnerable. People should stay out of the sun at midday, wear a hat and sunglasses, and frequently apply sunscreen with SPF 30 or higher.

Acetaminophen (Tylenol) is often recommended for pain relief in people with high blood pressure because most other options can raise blood pressure. A 2022 study suggests acetaminophen might sometimes have a similar effect.

Knuckle cracking doesn't "crack" a joint. The sound comes from gas bubbles bursting in the fluid inside the joint. While knuckle cracking is mostly harmless, other types of noises or the presence of pain can indicate a more serious joint problem.

Doctors advise that the best ways to lower risk for heart disease is to exercise, eat right, and adopt healthy lifestyle habits, like stress management, social engagement, and adequate sleep. But what do cardiology doctors do to practice what they preach? Three Harvard cardiologists share their heart-healthy habits and how they've overcome the same challenges their patients face.

When adult children express concerns about their parents' health, it benefits the parents to consider them. It could be that the kids are observing symptoms of conditions best treated early. If parents disagree with their kids' concerns, experts advise that parents simply express appreciation for the feedback and say they'll think about what the kids have said. If the parents want more information, experts advise writing down the concerns and either calling the doctor or bringing the matter up at the next appointment.
