Hot weather tied to increased odds of stroke

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.

Microplastics in arteries linked to heart disease risk

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.

New allergies in adulthood

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.

Noise exposure may raise risks of cardiovascular problems

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.

How do trees and green spaces enhance our health?

Trees enhance our lives by releasing oxygen, reducing pollution, and preventing flooding. Beyond all of these benefits, there is growing evidence that just being around trees and green spaces improves mood and overall health.

How to stay healthy during a drought

With climate change, rising temperatures are making many regions dry within the US and beyond. The effects of droughts on the planet and our health are complex, and include water shortages, higher risk of disease, changes in habitability, and worse air quality.

Bedbug invasion?

Bedbugs are tiny, flightless insects that feed on the blood of sleeping people and animals. After being nearly eradicated more than 50 years ago, bedbugs are now more resistant to pesticides and have resurged over the past decade. Bedbugs don't transmit diseases, but some people have an allergic response to their saliva. People can keep bedbugs from getting into their home by inspecting hotel bedding, unpacking clothes directly into a hot washer or dryer, keeping coats isolated while visiting others, and inspecting used furniture before bringing it home.

Weather and air pollution linked to heart-related hospitalizations

Lower temperatures, high wind speed, atmospheric pressure, high precipitation, and high degrees of pollution may raise the risk of being hospitalized for serious heart-related conditions. Modeling these factors may help forecast future heart problems.
