In a study published in the Journal of Applied Physiology, researchers at UNT Health Fort Worth found at-home heat therapy may hold the key to lowering blood pressure. A group of older adults wore heated pants for an hour a day, four days a week.

After eight weeks, their blood flow improved and their systolic blood pressure, which measures blood flow when the heart beats, dropped by around 5 points.

The study comes at a time when nearly 120 million American adults have high blood pressure, but only one in four of those adults has it under control. In Texas, about 32% of adults report being told by a health care professional they have high blood pressure. And in 2023, high blood pressure was a primary or contributing cause in over 664,000 deaths in the United States, according to the Centers for Disease Control and Prevention.
