Effects of high and low pressure on the human body.

[SrEstroncio]

Homework Statement

I was asked by my lab teacher to investigate the effects on the human body of being exposed to very high and very low pressures, and while I have found some good sources of info it is not that easy to find good and quotable sources, I was wondering if anyone could offer some help on that matter.

Thanks in advance for all your help.

What is your criteria for a quotable source?

 

[SrEstroncio]

The criteria's not too strict, I just don't see any teacher taking seriously info quoted from wikipedia or yahoo answers. The sources are alright as long as they at least state the authors name, and would be even better if they in turn stated their sources.

Do research on NASA's websites for low-pressure/vacuum.

NOAA for high pressure.

I can provide some information on the effects of high and low pressure on the human body based on current research and scientific knowledge.

High pressure, also known as hyperbaric pressure, occurs when an individual is exposed to pressures greater than normal atmospheric pressure. This can happen in situations such as deep-sea diving, high altitude mountaineering, or in hyperbaric chambers. The effects of high pressure on the human body can vary depending on the duration and severity of the exposure. Some common effects include ear pain, sinus pain, and changes in heart rate and blood pressure. Prolonged exposure to high pressure can also lead to decompression sickness, also known as "the bends," which is a serious condition that requires immediate medical attention.

On the other hand, low pressure, also known as hypobaric pressure, occurs when an individual is exposed to pressures lower than normal atmospheric pressure. This can happen at high altitudes or in situations where there is a sudden decrease in atmospheric pressure, such as during a plane's rapid descent. The effects of low pressure on the body are similar to those of high pressure, but in the opposite direction. This can include ear pain, sinus pain, and changes in heart rate and blood pressure. Prolonged exposure to low pressure can also lead to altitude sickness, which can cause symptoms such as headache, nausea, and fatigue.

In addition to these physical effects, both high and low pressure can also affect the body at a cellular level. High pressure can cause damage to cells and tissues due to the increased stress and strain, while low pressure can lead to a decrease in oxygen levels in the body, which can impact cellular functioning.

It is important to note that the effects of high and low pressure on the human body can be mitigated through proper training, preparation, and equipment. For example, divers and pilots undergo specialized training and use equipment such as pressure suits and oxygen tanks to protect themselves from the extreme pressures they may encounter.

In conclusion, exposure to high and low pressure can have significant effects on the human body. It is important to understand these effects and take necessary precautions to ensure the safety and well-being of individuals in these environments. Further research and studies are needed to fully understand the long-term effects of exposure to extreme pressures on the human body.
