People are advised to drink water regularly throughout the day, even if they do not feel thirsty, to help maintain body temperature and prevent dehydration. Limiting outdoor activities during peak hours, typically between late morning and mid-afternoon, is also recommended. Authorities suggest scheduling outdoor work or exercise during cooler parts of the day, such as early morning or evening. Wearing loose, light-coloured clothing made of breathable fabric can help reduce heat absorption, while using protective items like hats or umbrellas can minimize direct exposure to sunlight. Keeping indoor spaces cool is another key measure. Experts recommend using fans, keeping curtains closed during the hottest hours and taking cool showers to lower body temperature. Diet and Early Warning Signs Diet also plays a crucial role in coping with extreme heat. Light, easy-to-digest meals and water-rich foods such as fruits and vegetables can help maintain hydration levels and reduce strain on the body.
