Heat stress refers to the adverse effects on the body that occur when the environmental temperature is excessively high and the body's mechanisms for dissipating heat are overwhelmed. This can lead to a range of health problems, from mild discomfort and reduced cognitive function to life-threatening conditions like heatstroke.

The risks associated with heat stress are elevated in certain conditions and for specific populations. Factors that increase risk include high ambient temperatures, high humidity, direct sun exposure, lack of ventilation, and strenuous physical activity. Individuals who are more vulnerable include the elderly, infants, people with chronic illnesses such as cardiovascular or respiratory diseases, those taking certain medications, and outdoor workers or athletes.

Symptoms of heat stress can vary in severity. Mild symptoms may include fatigue, headache, dizziness, and nausea. As heat stress progresses, more serious signs can emerge, such as muscle cramps (heat cramps), fainting (heat syncope), and a rapid pulse. The most severe form of heat illness is heatstroke, characterized by a high body temperature (above 104°F or 40°C), confusion, loss of consciousness, and hot, dry skin. Heatstroke is a medical emergency requiring immediate attention.

Preventing heat stress involves several strategies. Staying hydrated by drinking plenty of fluids, seeking cool environments by staying indoors in air-conditioned spaces or using fans, wearing lightweight and light-colored clothing, and avoiding strenuous activities during the hottest parts of the day are crucial. For outdoor workers, regular breaks in shaded or cool areas and acclimatization to hot conditions are essential. Public health initiatives often focus on raising awareness of heatwave risks and providing cooling centers for vulnerable populations.
