I am used to being at sea level and i on vacation at 7800 feet. the air is dry and the altitude is cause nose bleeds. what can i do?

Assimilate: Going immediately from sea level to 7800 feet can cause symptoms of altitude sickness including headache, nausea, dizziness and in extreme cases, shortness of breath and confusion. Staying at a slightly lower elevation for 24-48 hours to assimilate will help. Otherwise stay well hydrated and avoid heavy exertion for the first few days. A humidifier can help with dry air causing nose bleeds.
