Long exposure to direct sunlight may cause dizziness, headache, nausea, weakness or mental confusion. These are symptoms of sunstroke and may lead to severe medical disorders. To avoid it, protect your body, especially the head, from the direct sun. Always wear a hat or head covering. Consider taking your noon breaks in a shady place during the hot days of summer. If you experience any symptoms, stay indoors or in a cool, shady place and drink a lot of water. If your body temperature rises to about 40°C you must be cooled off. If possible take a moderately cool bath or splash water over yourself repeatedly.

Any traveller to India risks an infection or disease that probably does not exist or is rare in their home country. The majority of diseases are transmitted by contaminated food or water, and many by insect bites. Prevention consists of vaccinations as well as the avoidance of risky food and insect bites. Choose restaurants where dishes are prepared to order: avoid ready-prepared food. Drink bottled or hot drinks. Be cautious with fresh juices and lassi (made from yoghurt): if you do drink one make sure that no ice or water has been added. Eat fresh salads only if you are sure the ingredients have been washed in clean water. Avoid unpeeled fruit.
