Heads up hikers: Altitude sickness can kill

Mountain hiking plans in your future? Something to be careful of is Acute Mountain Sickness (AMS), otherwise known as altitude sickness. Traveling too high too fast can actually kill you, in rare cases, and more commonly will just make you sick. 20% of people will notice symptoms when hiking in the 6,300-9,700ft range, and above 14,000 most people experience at least minor signs.

AMS is caused by a combination of the lower air pressure and oxygen levels at higher altitudes and can be characterized by fluid collecting around the lungs and the brain. Symptoms often include headache, insomnia, loss of appetite, nausea and vomiting, and dizziness. AMS is best treated by descending to a lower altitude and administering oxygen, and even better yet preventing it from happening altogether by climbing slowly and stopping at the first signs of illness.

Hiking is a great way to get outdoors and get fit, but make sure you're educated on the risks and take care of yourself!
