What are some common symptoms of heat stress?

Heat stress occurs when the body is unable to adequately cool itself, leading to an elevation in body temperature and various physiological responses. Common symptoms of heat stress include headache, dizziness, and nausea.

Headache can result from dehydration, which is often associated with heat stress. The body loses fluids and electrolytes through sweating, leading to a drop in blood volume, which can trigger headaches. Dizziness is another symptom due to a combination of dehydration and changes in blood pressure caused by heat exposure. Nausea can arise from both dehydration and the body's struggle to cope with increased temperatures, which can disrupt normal gastrointestinal function.

Understanding these symptoms is crucial for those working outside, especially in turf and landscape applications, as heat stress can pose significant health risks and affect decision-making and performance. Being able to recognize these signs allows for timely intervention, such as rest, hydration, and cooling measures, to prevent more severe heat-related illnesses.
