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.

When doctors say that it’s okay to take proton-pump inhibitors (PPIs) “on demand” for chronic heartburn, the advice doesn’t apply to everyone. PPIs inhibit the production of stomach acid, which can back up into the esophagus and can cause pain (heartburn) and damage the lining of the esophagus. People with damage to the esophagus often stay on PPIs long-term to prevent further problems. People without damage to the esophagus can take a short course of PPIs as needed.

Nutrient deficiencies are uncommon with a broad and varied diet. But aging, hormonal factors, or diet can leave women short of four key vitamins and minerals: vitamin D, iron, vitamin B₁₂, and calcium. Various tests can reveal nutrient deficiencies, including blood panels. Vitamin D and fish oil supplements may help prevent autoimmune diseases. Multivitamins are usually unnecessary, except in cases where age, pregnancy, digestive challenges, or certain medications interfere with the ability to get adequate nutrition.

Psychedelic drugs such as psilocybin (found in “magic mushrooms”) and 5-MeO-DMT (a compound derived from toad venom) are being tested for treating cases of depression that don’t respond to standard treatments. New depression approaches are needed since current treatments don’t work in nearly half of patients. Hallucinogenics may change longstanding thought patterns or promote new connections in brain neurons. Benefits of psilocybin on mood appear to be long-lasting. FDA approval for psilocybin will likely take several more years.

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.

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.
