How long do altitude headaches last?
How long do altitude headaches last? AMS headache is usually intense, throbbing and is either generalized or in the forehead. It develops within six hours to four days of arrival at high altitude and can last for up to five days. The headache often worsens with exertion, coughing, straining or lying flat.
What should you not do at high altitude?
Do not drink alcohol or do heavy exercise for at least the first 48 hours after you arrive at an elevation above 8,000 feet. Traveling to elevations greater than 9,000 ft for 2 nights or more, within 30 days before your trip, can help avoid altitude illness on a longer trip at a high elevation.
