You're heading to the mountains for a vacation. What can you do to avoid altitude sickness?
The American Heart Association suggests if you're hiking or climbing, for instance, move up the mountain slowly. Take a couple of days to reach 8,000 feet to let your body get used to the thin air.
If your headed to places like Denver or Aspen for fun, the association says avoid strenuous activity the first couple of days, drink plenty of water but don't drink too much alcohol and consult your doctor before your trip, if you think it's necessary.
Warning signs of altitude sickness can be noticeable at 7,000 feet or above. They include headaches, breathlessness, fatigue, nausea or vomiting, inability to sleep and swelling of the face, hands or feet.
