Doctors Near You for Heat Illness in Chilliwack

Heat illness refers to a spectrum of conditions that occur due to prolonged exposure to high temperatures, which can overwhelm the body's ability to regulate its internal temperature. This can lead to various symptoms ranging from mild heat-related disorders to life-threatening conditions. Common types of heat illness include heat exhaustion, heat stroke, and heat cramps. Heat exhaustion is characterized by heavy sweating, weakness, dizziness, nausea, and headaches. It results from the loss of fluids and electrolytes through excessive sweating. Heat stroke, the most severe form, occurs when the body's core temperature rises to dangerous levels, typically above 104°F (40°C), leading to symptoms such as confusion, seizures, loss of consciousness, and a lack of sweating. Heat cramps involve painful muscle contractions, often in the legs or abdomen, due to electrolyte imbalances. The primary causes of heat illness are prolonged exposure to high environmental temperatures, especially in combination with high humidity, which impairs the body's ability to cool itself through sweating. Physical exertion in hot weather, inadequate hydration, and wearing heavy or non-breathable clothing can also increase the risk of heat illness. Treatment for heat illness depends on the severity of the condition. For heat exhaustion, the affected individual should move to a cooler environment, hydrate with water or electrolyte solutions, and rest. Applying cool, damp cloths to the skin or taking a cool shower can also help lower body temperature. For heat cramps, rehydration and replenishing electrolytes are key. Heat stroke is a medical emergency requiring immediate action: move the person to a cool place, immerse them in cool water if possible, and seek emergency medical help. Preventing heat illness involves staying hydrated, avoiding strenuous activities during peak heat, wearing lightweight and breathable clothing, and taking frequent breaks in the shade or air-conditioned environments.
