What occupational diseases are prone to occur in summer?

During summer, high temperatures, stuffy indoor office environments, and prolonged desk-based work make office workers particularly susceptible to occupational heatstroke, occupational skin diseases, occupational visual fatigue, cervical-thoracic-lumbar muscle strain, and air-conditioning-related respiratory disorders. If you experience any physical discomfort, seek medical attention promptly.

1. Occupational Heatstroke: Prolonged exposure to hot, poorly ventilated work environments impairs the body’s ability to dissipate heat, disrupting normal thermoregulation. Persistent heat and humidity may cause dizziness, fatigue, excessive sweating, and even high fever—making this one of the most common occupational illnesses during summer.

2. Occupational Skin Diseases: Increased sweating in summer, combined with dust and oil residues, continuously irritates the skin. Prolonged skin exposure to a moist, non-breathable environment predisposes individuals to various dermatoses and folliculitis; outdoor workers face an even higher risk.

3. Occupational Visual Fatigue: Office workers often stare at electronic screens for extended periods. Coupled with dry indoor air and direct airflow from air conditioning, tear film evaporation accelerates, leading to dryness, soreness, and blurred vision. Chronic exposure may result in progressive visual decline.

4. Cervical-Thoracic-Lumbar Muscle Strain: Most office workers remain seated for long durations in fixed postures. Direct exposure to cold air-conditioning drafts on the torso and joints during summer exacerbates local circulatory impairment, causing muscular stiffness, soreness, and strain.

5. Air-Conditioning–Related Respiratory Disorders: Office spaces are typically enclosed, and prolonged operation of air-conditioning systems allows accumulation of dust and bacteria. Repeated inhalation of contaminated air irritates the upper respiratory tract, causing symptoms such as dry or sore throat and dry cough. Chronic exposure may lead to recurrent respiratory discomfort.

During work breaks, ensure regular window ventilation, adjust seating posture and ambient temperature appropriately, and avoid direct exposure to cold air drafts. Maintain adequate hydration, follow a light diet, and engage in moderate physical activity regularly—these measures effectively help prevent summer-related occupational health issues.
