The Caribbean's position near the equator means that the sun's rays in the region are very strong - use a high-factor sunblock (SPF 15 or more) and apply it liberally at least every two hours and after swimming or exercise. Keep sun exposure to a minimum, especially between the hours of 11am and 4pm; wear a hat and a shirt, drink plenty of water and make sure children are well covered up.

Dizziness, headache and nausea are symptoms of dehydration and should be treated by lying down in a shaded place and sipping water or other hydrating fluids. Should symptoms persist, or if you are suffering from hot, dry (but not sweaty) skin - potentially a sign of heatstroke - seek medical assistance immediately.
