Evidence suggests that chewing gum can help people feel more focused and less stressed. Chewing sugar-free versions can hinder cavities. But constant gum-chewing can tire jaw muscles, and xylitol-containing gum can trigger abdominal distress.

The body’s pH level supports a variety of crucial functions. Certain health conditions can create a pH disturbance. People can support a healthy pH by eating a balanced diet featuring fruits, vegetables, whole grains, lean meat, and fish.

As people get older, they may get clumsier because of multiple factors such as declining hearing and vision, loss of muscle, balance issues, and chronic health conditions. Addressing these issues can help people avoid injury from falls and other accidents.

With age, people develop brown spots, wrinkles, and sagging skin. Women are more likely than men to invest money and time to look younger. Sun protection and a variety of skin care products can help, including those containing alpha-hydroxy acids, retinols, vitamin C, and hyaluronic acid. Minimally invasive cosmetic procedures can also ease signs of aging. These include injections of botulinum toxin (Botox) or hyaluronic acid, laser treatments, and chemical peels. Skin care and treatments should be customized to each person.

Solo-agers are people 50 and older who aren’t married, don’t have children, and live alone. Many of them don’t have people they can count on to help them with household tasks or manage their ongoing care, if needed. While solo aging can offer perks, it can also leave older adults vulnerable to deteriorating mental and physical health. Solo-agers may count on help from siblings, neighbors, friends, community groups, or paid help. They can build their support by setting up a buddy system, staying in regular touch with loved ones, and tapping senior programs.

Radiation from diagnostic tests has the potential to damage tissue in the body, including cell DNA. Rarely, that can cause cell mutations that lead to cancer 10 or 20 years later. The long-term cancer risk from standard x-rays is considered very low; the risk from computed tomography (CT) scans might be higher. If a doctor orders a CT scan for someone who recently had that same type of scan, the patient should ask what the results might show, whether they’ll affect treatment, and whether an alternative test can be substituted.

In a 2025 randomized trial of about 1,000 people (ages 50 or older), followed for four years, those who took 2,000 international units of vitamin D₃ per day showed cellular signs that suggested they were aging more slowly compared with people who did not take the supplement. It’s unclear if this benefit would continue from taking daily pills longer than four years. Scientists do know that taking vitamin D₃ supplements is important for people with osteoporosis or with vitamin D deficiency (as determined by a blood test).

Scientists are trying to create a vaccine that would protect people against all different strains of the influenza (flu) virus. These vaccines are being designed to target parts of the flu virus that don’t change regularly and so are consistent across all strains. The perfect vaccine would also prevent symptoms (since current vaccines help prevent hospitalization and death, but not symptoms), and its effects would last for a lifetime. While such a vaccine is still many years away from reality, improved flu vaccines are expected in the meantime.

Arm tenderness is the most common side effect after vaccination. The injection stretches muscle fibers and triggers an immune response, causing discomfort. People can counter pain by moving the injected arm afterward and applying a cool compress or ice pack.

With influenza virus, a new vaccine must be developed each year to adapt to the virus’s changing structure.
