If you're healthy and don't have a history of cardiovascular disease, daily low-dose aspirin is no longer recommended as a preventive measure, says a new guideline released by the American Heart Association and American College of Cardiology. The risks of internal bleeding and other side effects outweigh the benefits of aspirin in this group.

The new guideline, which was based on numerous recent studies, does not apply to people who have had a heart attack or stroke or who have undergone a bypass procedure. The recommendation to take low-dose aspirin therapy in this group is unchanged.

If your hair has been thinning, an infusion of your body's own plasma may help grow it back, according to the American Academy of Dermatology.

A number of recent studies show that platelet-rich plasma (PRP) therapy is successfully regrowing lost hair. This includes a 2018 study in the International Journal of Women's Dermatology that found the technique was beneficial in treating androgenetic alopecia, a type of genetically and hormonally driven hair loss that affects as many as 35% of women by age 60.

There are lots of dubious claims and mysterious ingredients, but yes, by trapping water, moisturizing can help with dry skin.

Dry skin by itself isn't a medical worry, although serious cases can result in cracks and fissures that invite infection and inflammation. The real issue is discomfort — dry skin can be sore, tender to the touch, and often itchy (although not all itchy skin is dry). There's also the red, rough, scaly appearance lamented in many advertisements for moisturizers.

This is one problem that hasn't suffered from lack of attention: there are dozens of creams and lotions for dry skin. They are sold as moisturizers, which is more of a marketing term than a medical or scientific one. Indeed, routine skin care is a realm where there's little science to be found. Well-controlled studies of ingredients are few and far between. Companies keep information about ingredients proprietary and are careful to limit claims for what the products do to stay within FDA rules.

Q. My family has squabbled about oats for some time. Some members say that to get the biggest health benefit from oats you need to eat them raw, at room temperature, and moistened with water. Others say they should be cooked. Does cooking take something beneficial out of oats? Can you bring us some peace at breakfast time?

A. Eating a bowl of raw oats "moistened with water" doesn't sound all that appetizing. And I am not sure it makes sense from a nutrition perspective. Normal cooking takes little away from oats. In fact, cooking helps release some nutrients that your body can't extract from raw oats.

There are no official fitness guidelines for older adults, but the basic exercises for senior are the same at every age.

The average 65-year-old can expect to reach her 85th birthday, and the average 75-year-old will live to age 87. How we'll celebrate those birthdays — as the life of the party or immobilized on the sidelines — has a lot to do with how we spend our time today. Although none of us can be certain that we'll be spared debilitating disorders that could rob us of our mobility, there's no doubt that regular exercise will help improve our ability to function at almost any age or level of fitness.

Q. I am starting to have trouble reading. But I have heard that wearing glasses to help me read will make my eyesight worse. Is that true?

A. This is a common question. Many people believe that glasses can make eyesight worse, but that's more myth than reality.

The CDC’s Guideline on Prescribing Opioids for Chronic Pain helps doctors and patients manage treatment at safe levels and avoid dependence. Any plan to taper medication dosage should be personalized to the patient’s needs.

Regularly eating whole grains can help you lower “bad” cholesterol, triglycerides, and blood pressure. A diet rich in whole grains also “is associated with a lower risk of developing cardiovascular disease, type 2 diabetes, metabolic syndrome, and certain types of cancer,” says Dr. Qi Sun, an associate professor at Harvard Medical School.

In a study published in JAMA Internal Medicine, Sun and colleagues reported that eating whole grains may even extend your life. Sun used the diet information of more than 100,000 men and women whose health was followed for more than 20 years. The study found that those who regularly ate whole grains had a 9% lower overall death rate and a 15% lower death rate from heart disease.
