Hello Heat stroke is a common thing due to hot and humid environment. The best way is to avoid physical work. If necessary consume plenty of fluid, water (with proper salts and minerals in it). Physical cooling with sponging, fans, cooling blankets and even ice baths should be initiated immediately in conjunction with intravenous fluids. So order your employs cover their head with some cotton clothes, Chat Doctor.  Avoidance for hot and humidity is the best way. Good luck.
