A 2025 study found that using a high-efficiency particulate air (HEPA) filter to trap tiny particle pollutants may help lower blood pressure for people living near busy roads. Of particular concern are particles less than 2.5 microns in diameter, known as PM_2.5, which creates inflammation that damages blood vessels and contributes to high blood pressure. Nearly a quarter of Americans live near vehicle-congested roads, and many more people are exposed to pollution from wildfire smoke.

Simple, proven strategies to live a longer, healthier life can help people become super-agers, defined as people who reach the age of 70 without any major diseases such as heart disease, cancer, or dementia. These habits include doing strength training to preserve muscle mass, eating a mostly vegetarian diet that provides many healthful nutrients, and prioritizing healthy sleep habits.

An Indian-adapted Mediterranean diet includes vegetarian-focused meals flavored with an array of vibrant spices. The fiber-rich meals contain anti-inflammatory compounds that may provide heart-related health benefits. Healthy protein sources include legumes, featured in dishes such as chana masala (chickpeas in a tomato-based sauce) and dal (a soupy stew made from dried split lentils or peas). Tomatoes, eggplant, and peppers appear often in both the Mediterranean diet and the Indian-adapted version, as do leafy greens such as spinach.

Venous insufficiency can cause swelling in the lower legs and feet, a sense of heaviness in the legs, and in some cases, skin discoloration. Treatments include elevating the legs, walking, and wearing compression stockings.

The 2025 blood pressure guidelines recommend starting drugs to treat hypertension if people don’t meet blood pressure goals after three to six months of lifestyle changes. The guidelines also recommend that everyone with high blood pressure be screened for primary aldosteronism, and suggest that people with resistant hypertension (stubbornly high blood pressure) consider renal denervation, a procedure that disrupts some of the nerves around the arteries supplying blood to the kidneys.

A 2025 study suggested that people can lose more weight by eating minimally processed foods rather than ultra-processed versions, even those typically considered healthy.

A 2025 study suggested that people with diabetes who exercise regularly or in a “weekend warrior” pattern are significantly less likely to die earlier than peers who are inactive.

An October 2025 study found that at least 15 minutes of fast-walking each day was associated with longer life.

Celiac disease is an autoimmune digestive condition triggered by gluten, a sticky protein found in grains such as wheat, barley, and rye. Celiac disease is typically diagnosed later in life, and occurs more often in women. Symptoms include intestinal distress, weight loss, rashes, fatigue, and nutrient deficiencies. Celiac patients must adopt a strictly gluten-free diet, which can be challenging after decades of eating gluten. Helpful strategies include creating gluten-free kitchen areas, buying naturally gluten-free items, and examining food labels.

Inflammaging is chronic, low-grade inflammation throughout the body that occurs with aging. It is believed to accelerate aging and contribute to more than half of all deaths worldwide by driving various age-related diseases such as arthritis, autoimmune conditions, heart disease, cancer, diabetes, and Alzheimer’s disease. People can combat inflammaging through healthy lifestyle measures such as exercising, eating healthfully, controlling weight, managing stress, prioritizing sleep, and limiting alcohol and smoking.
