Regular application of a high-SPF sunscreen (SPF 30 minimum) is essential every two hours, even on cloudy days. Complement this with frequent breaks in the shade to reduce the risk of sunstroke or heatstroke.

Prevention of Heat-Related Illnesses

• Limit exposure during the hottest hours (between 12 p.m. and 4 p.m.).
• Seek coolness regularly: air-conditioned rooms, shaded areas.
• Quickly recognize signs of heat exhaustion (headache, nausea, severe fatigue) to act promptly: immediate hydration, rest in a cool place.

Protection Against Insect-Borne Diseases

• Daily use of appropriate mosquito repellents.
• Systematic wearing of long clothing in the evening or in rural areas.
• Using mosquito nets for sleeping when necessary.

Dietary Recommendations

It is recommended

• To consume only well-cooked foods
• To prioritize peeled fruits
• To avoid cold buffets or unpeeled raw vegetables

A varied diet rich in fresh local produce effectively supports the immune system against new tropical pathogens.

Adapted Physical Activities
