A healthy diet is a proven and powerful way to lower your risk of heart disease. Since dinner is often the main meal of the day, it’s a good time to feature foods that support cardiovascular health. Four Harvard physicians share their favorite healthy dinners, which focus on lean protein (such as tofu, fish, and chicken) and a variety of vegetables.
A 2025 study found that morning coffee drinkers faced lower odds of dying from cardiovascular disease—or any cause—over a 10-year period compared with people who drank coffee all day or people who didn’t drink coffee at all.
A 2025 study found that chronic stress is associated with higher stroke risks among women under 50, but not in men.
A 2025 study suggested that a structured exercise plan can significantly reduce the risk of falls among older women who take multiple medications.
Trichotillomania is a mental health disorder characterized by frequent, irresistible impulses to pull hair from the scalp or anywhere else on the body. It often results in embarrassing bald patches that people with the condition try to conceal. About one in 50 people has trichotillomania, and women are diagnosed and treated for it more often than men are. People with the disorder may pull hair when faced with stressors such as tension, loneliness, or fatigue. Among people who eat pulled hair, complications such as hairballs can be life-threatening.
Studies show that women’s pain experiences are often minimized, dismissed, or undertreated by clinicians. Women and men perceive pain differently. Factors contributing to women’s undertreatment for pain include lack of objective pain measures, uncertain diagnoses, clinician bias, and how women are socialized. Women can ensure their pain is taken seriously by communicating closely with clinicians about expectations, stating they recognize their pain may not be 100% relieved, and doing their own research on possible reasons for pain.
Kidney stones are increasingly common among Americans. Made of minerals and acid salts in the urine, the hard deposits cause symptoms when they get stuck in the ureter, the tube that leads to the bladder. Symptoms include excruciating pain, blood in the urine, nausea, vomiting, fever, and chills. Risk factors for kidney stones include low fluid intake, family history, pregnancy, obesity, high blood pressure, gastric bypass surgery, and eating foods high in salt or sugar. Most kidney stones pass on their own, but treatments can retrieve or destroy the stones.
A 2025 study found that the shingles vaccine reduced the risk of developing dementia by 20%. The study supports (but doesn’t absolutely prove) the theory that infections may be one cause of Alzheimer’s disease and possibly other forms of dementia.
Doctors are optimistic that artificial intelligence (A.I.) will one day play a role in curing and preventing Alzheimer’s disease. One example of A.I.’s application is its use in helping scientists learn how certain molecules might cause Alzheimer’s.
Mindfulness might help improve attention and memory. Mindfulness is the practice of focusing on the present moment, including thoughts, feelings, and all information coming in from the senses, such as sights, sounds, and smells. Many studies have shown that mindfulness helps people improve well-being, concentrate, engage more effectively in daily activities, and pay more attention. Attention is the most crucial factor when it comes to memory; whatever someone pays attention to is what he or she remembers.
