Clinical Causes: Prolonged exposure to high temperatures and direct sunlight while working outdoors on the deck or in other uncovered areas of the ship. Inadequate ventilation or cooling systems aboard the ship, leading to increased internal heat levels. Heavy physical activity in hot conditions without sufficient hydration or rest. Poor acclimatization to high temperatures, especially for crew members newly assigned to work in hot environments. Wearing heavy, non-breathable clothing or personal protective equipment that traps heat. Working during peak sunlight hours, usually between late morning and early afternoon.

Key Symptoms: Heavy sweating and dehydration Deep or rapid breathing Dizziness or lightheadedness Muscle cramps or weakness Headache

Diagnosis Path: Diagnosis typically involves a thorough assessment of the patient's recent work environment, symptoms, and physical examination. Medical professionals may check hydration levels, vital signs, and look for signs of heat exhaustion or heat stroke. Sometimes, additional tests like blood tests are performed to assess dehydration or electrolyte imbalances. The healthcare provider’s evaluation considers the duration and intensity of heat exposure alongside clinical findings.

Treatment Protocols: Treatment for heat exposure focuses on immediate cooling and rehydration efforts. Actions may include moving the affected individual to a shaded or cooler area, removing excessive clothing, and providing fluids, preferably electrolyte-rich drinks. In cases of severe symptoms such as altered mental state or loss of consciousness, urgent medical attention is required, including active cooling methods like cool packs or intravenous fluids. Long-term management involves preventing future heat exposure through education, proper hydration, adequate rest, and improved ship facilities for climate control.
