lämpöaltistuksesta

Lämpöaltistus, known in English as heat exposure, refers to the body's reaction to excessive heat. This can occur in various environments, including hot weather, industrial settings, or during strenuous physical activity. When the body is exposed to high temperatures, it struggles to maintain its normal internal temperature through mechanisms like sweating and vasodilation.

Prolonged or severe heat exposure can lead to heat-related illnesses, ranging in severity. Mild conditions include heat cramps, characterized by involuntary muscle contractions, and heat exhaustion, which can cause heavy sweating, dizziness, nausea, and a rapid pulse. More serious is heatstroke, a medical emergency where the body's temperature regulation system fails, leading to a core body temperature of 40°C (104°F) or higher. Symptoms of heatstroke include confusion, lack of sweating despite the heat, and loss of consciousness.

Factors that increase the risk of heat exposure include dehydration, certain medical conditions like cardiovascular disease, age (very young and elderly are more susceptible), and taking certain medications. Prevention strategies involve staying hydrated, avoiding peak heat hours, wearing light and loose-fitting clothing, and acclimatizing to hot environments gradually. Seeking cool environments and resting are crucial if symptoms of heat-related illness appear. Prompt medical attention is vital for heatstroke.
