The more distance you put between yourself and the bulk of the mass of the earth, the less gravitational force it exerts on your body. By one estimate, a person who weighs 150 pounds on the surface of the earth would weigh approximately 149.92 pounds at 10,000 feet above sea level.

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it’s snowing), the temperature decreases more slowly with height.

Most men won’t notice any effect until about 5,000 feet; even at one mile above sea level, breathing is comfortable at rest but becomes labored with exertion. And the higher you go, the harder your lungs have to work to take in the oxygen you need.

While you may fart more frequently at higher altitudes, higher elevations do not make you poop more often. So, while higher altitudes make you pee more and fart more, they do not make you poop more.

High altitude sickness and IBS I learned, though, that high altitude can also aggravate diarrhea or constipation, and cause “intestinal gas” – i.e., bloating and increased farts. There’s actually a cute name for it: locals call it the “’tude toots.”

The major cause of altitude illnesses is going too high too fast. 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.

As cabin pressure falls while flying, gas starts to expand. As a result, you may feel pressure in your stomach or digestive system. Gas and bloating are common. Bloating occurs when food is not digested properly.

Spending a lot of time on airplanes increases your risk of gaining weight, a recent study published in The New York Times has revealed. The most at-risk group are business travelers who fly regularly: from a few times a month to almost every day.

Swollen legs, feet or hands Our bodies are designed to move to help blood flow, so when you stop moving during a long flight, your blood tends to pool in your legs. “Our calf muscles are a very efficient pump for squeezing the veins and pushing blood back to our heart,” said Dr.
