A 2025 study addressed the role of genes versus lifestyle habits and life circumstances in influencing a person's health. Researchers found that genes seemed to have a stronger influence than lifestyle and life circumstances for some diseases, including dementia, macular degeneration, and certain cancers. For other diseases, such as atherosclerosis involving arteries of the heart and brain, rheumatoid arthritis, and diseases of the lung, heart, and liver, lifestyle and life circumstances had a stronger influence than genes.

With ticks thriving in a wider geographic range, appearing earlier and sticking around later, it's important to stay vigilant about protecting yourself against ticks that cause Lyme disease and other illnesses. Learn some steps you can take to avoid tick bites.

Direct-to-consumer (DTC) drug ads promoting treatments for arthritis, cancer, heartburn, psoriasis, flagging memory, and more are all everywhere you look.

Sepsis causes or contributes to an estimated 20% of all deaths worldwide. The condition begins with an infection that spreads and over activates the immune system, which releases damaging inflammatory chemicals that lead to organ failure.

The condition may be avoided by stopping bacterial or viral infections from occurring or worsening.

People often don't realize they are at high risk for falling until after they've taken a tumble. Studies have shown that maintaining optimal core and postural strength, good balance, and flexibility in the calves and hips are the best ways to prevent falls. At-home tests can help highlight weaknesses in these three areas that can then be addressed with a personal trainer or physical therapist.

During midlife and later, men often experience a lower energy level, sour mood, and decline in sex drive. These changes have been tagged with the term "male menopause." A low testosterone level may be a factor. Lifestyle changes, such as losing weight, increasing exercise, and following healthy sleep patterns, can help raise low levels.
