Tourists suffering from breathing or heart-related problems should consult their doctor before visiting Ladakh. Otherwise, if you let your body acclimatize properly, Ladakh is safe for all. Avoid smoking/drinking here.
Still, if anybody is on medication, he/she should first consult the doctor first. We strongly request our guests to get themselves medically examined before visiting Ladakh. Also, they should eat healthy and drink enough water and take all precautions to keep their body fit.
