Medical treatment and dentistry are of relatively high quality in Baja's cities. There are public IMSS clinics or Red Cross stations in nearly every other town. If you are staying in Los Cabos, there is a hospital in San José del Cabo.

Hotels and restaurants in Baja serve only purified drinking water and ice, so there is no need to worry or to have to order mineral water. Tap water should not be consumed anywhere other than in the hotels. You can buy bottled, purified water in all of the grocery stores. As for the food, you may want to go easy if you are not used to spices and rich food. Also stick to the restaurants and hotels rather than eating food from street vendors, and you should be fine. Many "gringos" eat street food without having any problems with it, but it is always a good idea to be careful, especially if you have never visited Mexico before.

Be aware that the sun in Baja can be exceptionally strong, and bring plenty of suncreen, a hat and sunglasses. More people are afflicted with sunburn than any other illness while visiting. It is also important to drink plenty of water since the climate is very dry most of the time.
