What happens when you go from high elevation to low?

Altitude sickness, also called acute mountain sickness, happens when your body is unable to adapt to a low-pressure, low-oxygen environment — typically at about 8,000 feet above sea level. This can cause breathing issues and a host of other symptoms which can range from very mild to life-threatening.

Given time, your body can adapt to the decrease in oxygen molecules at a specific altitude. This process is known as acclimatization and generally takes 1-3 days at that altitude.

How long does it take to recover from altitude sickness?

Altitude sickness usually resolves by itself within six to 48 hours. The main treatment involves going down to a lower altitude (descent) as quickly and safely as possible. The symptoms of moderate altitude sickness generally improve within 24 hours on reaching an elevation that is at least 1,000 to 2,000 feet lower.

Why do your fingers get fat when you hike?

Exercise increases blood flow to your heart and lungs, as well as to the muscles you’re working. This can reduce blood flow to your hands, making them cooler. In turn, the blood vessels in your hands may react by opening wider — which could lead to hand swelling.

Can altitude sickness cause long term effects?

If you take care and move to a lower elevation when you feel symptoms, altitude sickness has no long-term negative effects. You’ll recover within a few days. Once you feel better, you can continue to travel to higher elevations, as long as you do so slowly and carefully.

Can altitude sickness cause permanent damage?
