Transcript of The Physical & Mental Affect of Mount Everest

A slideshow presentation by: Alexis Borsky
Geography LP5 The Physical & Mental Effects of Mount Everest on the Human Body Temperature Avalanches Lack of Oxygen/High Altitude Lack of Oxygen Avalanches occur often on Mount Everest.

Avalanches can quickly bury and kill climbers - and they do, often.

Avalanches can also cause glaciers to crack and then be covered by snow. If these cracks are not visible, hikers can easily take a step to their death. The oxygen levels at the top of Everest are only a third of what they are at sea level.

Humans need oxygen to survive and keep their bodies going - therefore, the less oxygen, the worse the body works.

Some common symptoms of this are headaches and shortness of breath.

Obviously, being on a mountain that is covered in snow will be cold.
The first thing that someone's body would face, would be the cold.

Temperatures at the top are typically around 36 degrees C below zero in the winter and can drop as low as 60 degrees C below

This can cause cases of hypothermia & frostbite. High Altitude Humans cannot survive for any length of time at elevation above 26,000 feet (8000 m), which on Everest is known as the "death zone." At this altitude, the human body is unable to acclimate to the low oxygen and begins to deteriorate.

Most climbers must use oxygen and will have difficulty sleeping. A Body's Reactions At high elevation, the body will compensate by producing more red blood cells and functions should return to normal. At extremely high elevations, the brain can actually swell and blood vessels begin to leak, resulting in High Altitude Cerebral Edema, or HACE. High Altitude Pulmonary Edema, or HAPE, occurs when fluid accumulates in the lungs. How Climbers Avoid These Conditions Everest climbers typically make several trips up and down the mountain.

They take it a little further each time to increase their immunity or tolerance to the altitude.

Eventually, they hope to acclimate to the elevation at the top of Everest. Mental Effects Climbing mount Everest is very physically draining on a human body.

What about the human mind? It's probably just as equally draining. Exhaustion Because a hiker would be climbing all day long, their body would become very weak an tired.

When a body is physically strained, the mind begins to react the same way.

A hiker may experience being frustrated, upset, sad, confused or just plain exhausted. Fear A climber would be constantly faced with obstacles on Mount Everest. Whether it be severe storms, avalanches, glacier cracks or sunburn.

With these obstacles surrounding a hiker in every direction, fear can set in and cause someone to panic and become not well mentally. Hallucinations Because of the environmental conditions taking a toll on ones brain, a hiker may experience mild to sever hallucinations which can end very badly. Shortness of Breath This subject is closely related to a mental state of mind while climbing.

When there is less oxygen, the brain tells the body to breathe less. Because of this shortness of breath can become a health hazard very fast. Overall, most climbers who successfully made it to the summit, are in good health and are happy about their climb.

While some do experience negative reactions, even death, many people are still continuing to plan their trips to the top of Mount Everest.
