Preventing Swelt

There are several ways to prevent swelt, such as staying hydrated, wearing loose and breathable clothing, taking breaks in shady or cool areas, and avoiding strenuous activity during the hottest parts of the day.

Case Studies

In a study conducted by the National Institute for Occupational Safety and Health (NIOSH), it was found that outdoor workers are at a higher risk of swelt during heatwaves. By implementing cooling measures and providing adequate hydration, the incidence of swelt among workers decreased significantly.


According to the Centers for Disease Control and Prevention (CDC), an average of 702 heat-related deaths occur in the United States each year. These deaths are largely preventable through proper education on the signs and symptoms of swelt, as well as timely intervention and treatment.
