• Avoid direct sunlight between 11 AM – 4 PM.
• Wear light, breathable clothing and use hats/shades.

Hypertension and cardiovascular complications surge during extreme heat waves, requiring immediate medical attention for vulnerable populations.

Dehydration symptoms often appear subtly—drink water consistently rather than waiting for thirst signals. Avoid outdoor activities during peak afternoon hours to minimize exposure to dangerous mercury levels.

Health professionals recommend monitoring body temperature regularly and seeking shade whenever possible throughout daytime periods. Stay indoors with adequate ventilation or cooling systems to prevent heat-related medical emergencies effectively. Light-colored clothing helps reflect sunlight while loose fabrics allow better air circulation around skin. Symptoms like dizziness or nausea demand immediate response—never ignore early warning signs of heat exhaustion.

Weather System and Rainfall Forecast

Office workers remain cautious as temperatures keep hovering near 41°C with meteorological systems likely to bring scattered precipitation patterns. Atmospheric pressure zones shift unpredictably across coastal regions during intense heat waves.

Western disturbances interact with monsoonal moisture creating temporary relief possibilities. Forecast models suggest brief cooling episodes may interrupt sustained thermal stress periods.

Safety Measures and Precautions

• Keep ORS or electrolytes handy to prevent dehydration.
• Use sunscreen to protect skin from burns.
• Never leave children or pets in parked cars.
• Take frequent breaks if working outdoors.

• Check on neighbors and vulnerable people regularly.

Outdoor workers must drink four litres of water daily to counter excessive sweating during peak afternoon hours. Medical experts urge people to wear light-coloured, loose-fitting clothing and use a cap, scarf, or umbrella when venturing outside. Citizens are advised to take necessary precautions against heat-related illnesses by avoiding outdoor activities in direct sunlight. Indoor workers should aim for 13 to 15 glasses daily to ensure proper hydration.

Drinking plenty of fluids at regular intervals, including lemon or yoghurt-based drinks like lassi, helps stay cool and prevents dehydration. Professionals recommend avoiding heavy, spicy, and fried foods while opting for light, fresh meals to reduce internal body heat. Protect yourself by staying hydrated and monitoring any unusual symptoms that might indicate heat exhaustion.
