How Does Hypothermia Affect The Human Body

In this assignment I will be reviewing the different effects of exercise on the body system including the acute and long term using the pre-exercise, exercise and post-exercise physiological data which I collected based on interval and continuous training method. I will also be including the advantages and disadvantages of these, also the participants’ strengths and areas where they can improve on.

Numerous climbers have experienced the harsh effects of high altitudes when traveling up mountains due to the lack of oxygen and

The evidence surrounding the topic of therapeutic hypothermia post cardiac arrest is one lathered in potentially advantageous benefits, as well as harmful side effects. Although this procedure has potentially lifesaving and neurologically preserving implications, it does come with various side effects which can be dangerous in general or if left untreated. This paper will first address the many benefits, some of which include prolongation of life, retention of neurological function. It will then shed light upon some of the subsequent risks and harmful effects that are associated with therapeutic hypothermia. Lastly the paper will discuss why or why not the overall benefits outweigh the aggravating factors. Thus, being a topic of much controversy

Induction Phase. This is the first phase of therapeutic hypothermia. The aim of this phase is to deliberately reduce the patient’s core body temperature to a degree where mild hypothermia is induced. The target temperature for this phase of therapeutic hypothermia is roughly 32-34 °C, although the exact target temperature varies between healthcare facilities. The induction of mild hypothermia can be achieved through a variety of different methods, including ice packs, cold saline infusion, external cooling pads, and intravascular cooling. Sedatives and neuromuscular blockers are often administered in conjunction with these cooling methods to prevent shivering thermogenesis, which could otherwise increase the amount of time required to reach

When you work out in a low temperature environment, keep yourself warm and dry at the same time. Doing so will ensure you are at your peak conditions and does not affect your performance.

At extreme altitudes, sleeping becomes very difficult, digesting food is near-impossible, and the risk of HAPE or HACE increases greatly. HACE may include profoundly inhibited mental function, hallucinations, loss of muscle coordination, impaired speech, severe headache, nausea or vomiting and coma. HAPE may include extreme difficulty breathing, very rapid breathing rate, exhaustion, lack of motivation, pale complexion, constant coughing and gurgling sounds coming from chest. The death zone, refers to altitudes above a certain point where the amount of oxygen is insufficient to sustain human life. This point is generally tagged as 8,000 m (26,000 ft). Any time that the temperature is below -4°C (25°F), skin's freezing point, people are at risk

The shivering, teeth chattering, and chill in your bones are difficult consequences to bear when going outside with a wet head. You spent more time in the shower than you had intended on that morning, and decided to ditch the blow dryer for the slight chance you might be on time for school. The worst feeling of all, however, is the dread you feel for the inevitable sickness that will result from your struggle with punctuality - you’re going to get a cold. After all, everyone knows that going outside with wet hair will undoubtedly make you sick, right? Though this may come as a surprise, it has never been proven that going outside wet or even being chilly can cause the common cold. In fact, the only thing that can cause it is a virus caught from other people.

When a person lives in a place such as Alaska, Northern Idaho, Eastern Montana and other places that get so frigid, it is almost frightening, they get used to dealing with the cold. Cold is quite an in-conceptual word that could be pictured as anything from negative sixty-three degrees to “a warm,” forty-two degrees; it all depends on where you live.

It is interested that you chose to highlight Altitude Sickness, a condition that is rarely discussed. Symptoms occur in three stages that range from mild to severe. Altitude sickness can affect anyone who goes to high altitudes without giving the body time to adjust to the changes in air pressure and oxygen level. The more rapidly a climb to high altitude, the more likely that altitude sickness will develop. Altitude sickness also is more likely to develop when climbs are more difficult and take more energy, compared with a slow and easy climb ( Cleveland Clinic Foundation, 2013). Patients presenting with severe symptoms related to Altitude Sickness are predisposed to respiratory acidosis due to the increased elimination of hydrogen ions and

When one is involved in outdoor activity, the weather and environment is not to be taken lightly. Cold injuries will happen when the weather conditions are cold, windy, or wet. Cold injuries are classified into 3 categories: decreased core temperature (hypothermia), freezing injuries of the extremities, and nonfreezing injuries of the extremities.1 Hypothermia (core temperature below 95°F) is classified as mild, moderate, or severe, depending upon how low the core temperature is measured.1 Hypothermia occurs when there is a long exposure to cold, wet, or windy conditions during activity.

The human mind is a complex and delicate system that is affected by the smallest change in environment. Even the most conditioned of mindsets face difficulties when exposed to the extreme conditions of altitude. All it takes is 1,500 meters to impair a climbers reaction time, after 6,000 meters they will begin to experience hypoxia. Hypoxia is the condition in which a person's body tissue does not receive an adequate amount of oxygen. A combination of hypoxia and the effects of sleep deprivation can be misleading and even deadly in dire situations.

With regards to elevation, high altitude is defined as a height of 1,500-3,500 meters (4,900-11,500 ft.) but can differ by a 1,000 ft., depending on the defining source. The definition of elevation continues with very high altitude, which is 3,500-5,500 meters (11,500-18,000 ft.) then continues to extreme altitude of which is above 5,500 meters (18,000 ft.). Within healthy individuals, substantial clinical changes are difficult to exhibit at elevations lower than 1,500 meters. But once the human body reaches altitudes at or above high altitude, the adverse effects on the human body become increasing pronounced and considerable. As altitude increases, the barometric pressure falls and the environmental partial pressure of inspired oxygen declines. The reduction of inspired oxygen, in combination with other environmental factors such as a decline in temperature, humidity, paired with physical activity, the human body must be able to compensate for the adverse effects opposed primarily on the cardiovascular and respiratory systems.

Altitude sickness is an illness you can get from ascending too high above sea level too quickly without acclimatizing to the decrease in oxygen levels. Altitude sickness, also called acute mountain sickness, is caused by exposure to low partial pressure of oxygen at high altitude. At high altitude atmospheric pressure is lower than at sea level. Because of the lower pressure the air expands as it rises which causes it to cool, thus high altitude air is cold. Normally the

“ If body temperatures goes higher than about 100 F or lower than about 97 F, problems may develop.” (Nagel 419). Hypothermia has many causes. The most common cause is prolonged exposure to cold weather. Furthermore, it can also be triggered when wearing wet clothes when it’s cold outside. Hypothermia can also occur in temperatures above 40 degrees Fahrenheit, if your body temperature drops from being wet. It spawns a number of symptoms, ranging from lack of coordination to loss of consciousness. These symptoms include cold and pale skin, intense shivering, slurred speech, rigid muscles, and disorientation.

Cabin pressurization is also an important aspect, as beyond the altitude of 3000 meters the low pressure thin air can cause diseases like altitude sickness, barotraumas, hypoxia and decompression sickness. Among them hypoxia can lead to sluggish thinking of brain followed by loss of
