Health Ministry Issues Warnings

The Ministry of Health has intensified public awareness efforts, urging people to take preventive measures against heat stress and sunstroke. Dr. Shamsa Al Harthy, Head of school and university health programmes at the Ministry of Health, stated that "elderly aged 65 and above, infants and children under four years old, outdoor workers exposed to direct sunlight, employees working in enclosed spaces without air conditioning, and pilgrims are most susceptible to heat stress and sunstroke."

Symptoms requiring immediate medical attention include excessive sweating, severe fatigue, headaches, nausea, vomiting, dizziness, extreme thirst, muscle cramps, rapid heartbeat, and elevated body temperatures ranging between 38 and 39.5 degrees Celsius. Changes in skin condition, including redness and excessive warmth or cold, clammy skin accompanied by paleness, should also be regarded as warning signs.

Proper hydration remains the most effective defense against heat-related illnesses. People exposed to hot weather should drink water regularly throughout the day, recommending between two and four cups of water every hour when outdoors in high temperatures. Individuals undertaking physical activity under the sun should replenish lost salts and minerals and avoid beverages containing high levels of caffeine or sugar. Those working or exercising outdoors are advised to drink one to two cups of water every 15 to 20 minutes. The public is urged to avoid strenuous outdoor activities between 10 a.m. And 4 p.m. Workers in hot environments should take frequent breaks in shaded or air-conditioned areas and wear loose-fitting, light-colored clothing. The use of hats, sunglasses, and sunscreen is also recommended.
