General medical care in Dubai, Abu Dhabi, and Sharjah is quite good, with clinics for general and specialized care widely available, including some which are now open 24 hours a day. Hospitals in the major centers are well-equipped to deal with any medical emergencies. There is an ambulance system in all major population centers; however, coverage can be patchy in the more remote areas. Ambulances are designed for transportation rather than providing care as first responders, so don't expect top-flight on-site care. The main government hospital in Abu Dhabi is quite good; in Dubai, The government hospitals are Rashid hospital, which has a new Trauma Centre and Dubai Hospital which are very good. Welcare Hospital American Hospital Zulekha Hospital NMC Hospital, and Belhoul Hospital in the private sector all have a good reputation. The country is free of malaria and prophylaxis is not needed.

The water is safe to drink in the UAE, although most people prefer bottled water for its taste.

The heat in summer can reach 50 degrees C (122 degrees F), so avoid outdoors activity at the height of the day and watch out for signs of heat stroke. Be sure to drink lots of water as dehydration happens easily in such heat. If traveling off road (most of the country is desert), ensure you carry sufficient water to allow you to walk to the road should vehicles become bogged.

Although the UAE is somewhat more accommodating to handicapped travellers than other countries in the Mideast, it would nonetheless be a difficult country to navigate in a wheelchair. Curbs are high and there are few, if any, ramps or other accommodations. This includes an almost complete lack of handicapped-friendly bathrooms.
