ACUTE MOUNTAIN SICKNESS
Acute mountain sickness or AMS is caused due to a lack of oxygen at higher altitudes. Headache, nausea, disorientation & breathlessness are symptoms of AMS. AMS can affect anyone regardless of age or fitness. The only cure for AMS is to descend to a lower altitude or to inhale oxygen from a cylinder.
There are various ways to try and prevent AMS. The best advice is to rest in Manali for 2 days to be able to acclimatise to a higher altitude. Shanag Village, Manali is at an altitude of 2200 meters which is a good altitude to acclimatise at before going further up.
Make sure you are well rested and have enough warm clothes. Drink a lot of water as the climate is extremely dry and could lead to dehydration which in turn could lead to AMS. Avoid consuming alcohol and smoking. Avoid exertion at high altitudes. Take a medicine like Diamox to lower your chances of getting AMS. However, it has side effects such as numbing of fingers and toes and tingling sensations.
