Chemical pollutants such as lead, perfluoroalkyl and polyfluoroalkyl substances (also known as PFAS), and pesticides may contribute to heart disease risk. Possible routes of exposure for all three include drinking water and food. Residue and dust from many common items (such as water-resistant clothing and personal care products) may expose people to PFAS. People can limit their exposure by testing and, if needed, filtering their drinking water; choosing PFAS-free products when possible; using non-chemical pest control methods; and choosing organic foods.

Adjusting to new surroundings, such as a new or remodeled home, can affect people's hearing ability. Certain home features absorb sound, making it easier to hear. These include carpeting, paneling, curtains, and upholstered furniture. Other features allow sound to reverberate, making hearing more difficult. These include hardwood floors, cathedral ceilings, and minimalist decor. Hearing aids don't necessarily help, since they magnify all sounds.

People who have or are at risk for cardiovascular disease should be extra cautious when exercising outside when it's hot, humid, and hazy, as they are more vulnerable to the hazards of high temperature and air pollution. To exercise safely during a heat wave, people should avoid being outside during the middle of the day; wear light-colored, lightweight clothing; and be careful to stay hydrated.

A variety of factors seem to account for why mosquitoes bite some people more than others. These include a person's scent, blood type, and breathing patterns. People can minimize bites by using fragrance-free products and wearing long sleeves and pants.

Wondering how to save money, stay cooler, and be kinder to our planet during a long, hot summer? These five tips help ensure maximum fun and suggest ways to stay comfortable and safe this summer while making sustainable choices to benefit the environment.

Mounting evidence suggests that wildfires, which are increasing in intensity and frequency, contribute to skin problems, including eczema flares. Here's what you need to know to protect your skin from wildfire pollution.

A 2024 study suggests that exposure to high temperatures may increase the risk of an ischemic stroke. High temperatures may trigger dehydration, which can make the blood more viscous and more likely to clot.

A 2024 study found that people with microplastics in the plaque clogging their neck arteries were about four times more likely to have a heart attack or stroke than people with plastic-free plaque.

Contrary to common assumptions, new allergies can emerge well into adulthood. New food allergies are more common than new seasonal ones, and shellfish is the most prominent late-emerging allergen. Women are more likely to develop food allergies in adulthood than men and to grapple with severe food-related anxiety. Some people with childhood allergies, such as those to peanuts or pollen, stop having symptoms when they reach adulthood. People who experience potential new allergy symptoms should see their primary care doctor or an allergist.

A 2023 study suggests that long-term exposure to transportation noise from cars, trucks, trains, and planes is associated with an increased risk of cardiovascular disease.
