Extreme temperature acclimation in humans.

“Everybody talks about the weather, but nobody does anything about it.” – Mark Twain November 30, 1835 – April 21, 1910

Many of us believe that there is little we can do about weather conditions; I included. My situation has me moving from a rather cold to temperate climate to a rather hot and sticky one. So I set out in search of information on acclimation to extreme temperatures.
• Heat acclimatization identifies biological adaptations that lessen physical strain (e.g., heart rate and body temperature), improved comfort and protection of vital organs from heat injury. (U.S. Army Training and Doctrine Command (TRADOC) manual on heat acclimation, Pub.-July 2012)
• Heat acclimatization speaks directly concerning a certain environment, (e.g., a desert, jungle or the arctic.) Acclimatization to similar environments really improves comfort levels and ability to be active. (U.S. Army Training and Doctrine Command (TRADOC) manual on heat acclimation, Pub.-July 2012)

None of us can control snow, rain or wind, but we can train our bodies to adapt better, perform better and be less stressed. Humans can employ very similar techniques when acclimating to extreme environments, both hot and cold. Acclimation occurs in direct response to an ever changing environment. Acclimatization is the specific physiological changes which occur. Capillaries open wider to allow for more warm blood to enter in cold climates. Blood is redirected in heat to better more efficiently cool our bodies. Even psychological changes occur in this transition. We begin feeling less stressed by extreme temperatures and we begin emotionally feeling that “maybe it is not so hot/cold after all”. Our perceptions effect our levels of endurance greatly.

Why would we bother to acclimate other than for shear…...

Eradication of Poverty and Extreme Hunger

...Eradication of Poverty and Extreme Hunger Not everyone is born into a rich family. Those lucky enough to have been born into one have a responsibility to help those not so blessed. The United Nations' job is just that. They are an international agency whose aim is to eliminate poverty, illiteracy, and disease, stop environmental destruction, and encourage democratic rights and freedoms. Poverty and extreme hunger are something that are affecting most country in the world; no matter how big or small, rich or poor. This issue causes the most pain today, and is also the biggest threat to a person's future. Eradicating poverty and extreme hunger are the top priority of the United Nations in the 21st century because it will reduce the amount of malnutrition in people and improve their education. One of the reasons why poverty and extreme hunger must be eradicated is because without it there would be a dramatic drop in the number of malnourished people around the world. Poverty and hunger can affect young and old and is the biggest contributor to malnutrition. This can be seen in the Central American country of Guatemala. The Guatemala Poverty Assessment states that, "There is a strong correlation between poverty and malnutrition, as four fifths of malnourished children are poor" (Guatemala Poverty). In politics, a 66% super majority is rarely required when deciding on an issue because of the difficulty in achieving it. Therefore, when a supermajority is achieved, it can......

Live Life to the Extreme

...Writing 101 Live Life to the Extreme Everyday in life, one passes by those people that just seem unhappy. It seems like they are just having a bad day every day. Normally one sees them juggling a lot of things, like a briefcase, coffee, purse, bags, and other articles. They are almost running from the office to their car, to home and then back out to do other things. They have their phone constantly up to their ear talking, talking, talking and most have even upgraded now to a hands-free Bluetooth so they can juggle even more things. Doesn't one feel like just giving them a vacation or just a few minutes to sit down and relax? Do they even know how to relax after working so hard for so long? Everyone deserves that "me" time. This is why overworking creates an unhappy life to those that do not slow down and take breaks. Overworking will affect the person eventually and almost always it is in the negative aspect. If a person is constantly on the go and thinking about only work, that means that they may not be resting their brain or getting sleep. No sleep makes almost everyone grouchy, disconnected or both. When someone is too preoccupied with work or working in general, whether on a presentation or a sport or in a big corporation, this may make them forget about simple tasks like eating, sleeping, exercising or taking breaks to rest. This all leads to health problems! Think about this, if a person is too busy to eat, rest, or do simple tasks, does one really think they......

Climate of Extremes Book Review

...Climate of Extremes Book Review & Personal Reflection on Global Warming When talking to my family over thanksgiving break about school and my current class load for the semester, one of the more interesting topics that was brought up was the debate over global warming. It was interesting to hear the viewpoints of my mother’s side and fathers’ side of the family. For the most part my mothers’ side of the family are hardcore republicans and use faith as a basis for most of their political positions, while my fathers’ side (not my father however) tend to lead more towards the democratic viewpoint on politics. While I am a catholic and would consider myself to lean towards more of a conservative viewpoint, I try to separate faith from politics and focus more on what I believe is the core of the issue being debated and how it can be solved, not necessarily to benefit the majority, but rather what would be a fair compromise between to the two arguing sides. With this being said my two sides of the family did not see eye to eye on global warming (side note: these conversations were at two different family parties as I would never try to talk politics especially given the circumstance of two very different viewpoints in my family). After talking a lot about global warming my uncle told me about a book he had read about it entitled Climate of Extremes. I decide to read this book and write a report on it, to obtain more knowledge on the subject of global warming. Like......

Chris Burden’s Extreme Measures Exhibition

...The New Museum hosted Chris Burden’s Extreme Measures exhibition, featuring two of his more prolific and socially significant artworks: Shoot and LAPD Uniforms. Shoot, one of his premiere performance works, was a presentation of Burden’s subjective examination of being shot. LAPD Uniforms, created in response to the social outrage incited by the Rodney King beatings and subsequent acquittal of the offending LAPD officers, was a sculptural representation of police intimidation. Seven police uniforms, accurate to those worn by the LAPD in the 90s, were arranged in such a way that from a distance they appeared ordinary, but up close, they are realized to be considerably oversized. While each art piece was a curiosity in and of itself, and observably relevant to the social landscape of their respective eras (the seventies and the early nineties), my personal reaction to Shoot made it the standout between the two works. LAPD Uniforms spoke to me as a commentary on the times, which I could understand clearly. Shoot, on the other hand, while personally meaningful to the artist as framed by his interviews following the performance, rebounded against an innate distress that I, and I’m sure many others, have against self-damage. It invoked powerful negative emotions that left me questioning the underlying messages of Burden’s act. Why would someone shoot themselves simply to understand it? All evidence and common knowledge that has been accumulated since the dawn of the gun era......

Science Extreme Weather Unit

...Extreme Weather Unit Abstract This unit will study extreme weather on Earth but more specifically Mars and Venus. In the first steps it outlines the summary of this unit. The steps that the students have to take in studying these planets are outlined in the objectives. There are three cognitive objectives, one psychomotor, and one affective objective. The students will take this new knowledge of these planets and have to compare and contrast it with each other as well as weather on Earth. They will then have to assemble their own measuring tool for Mars or Venus and then have to defend their tool as the last step in this unit. As the students go through this unit they will be going through the levels of Bloom’s Taxonomy. They will start in the knowledge category as they start off describing weather but will finish in the evaluating category with their final creation presenting and defending why their tool would work on Mars or Venus. By taking these steps, utilizing back ground knowledge, and being able to create and make a measuring tool this would be a great lesson to add to any weather unit that is hands-on and engaging. Extreme Weather Unit Studying extreme weather on other planets is a very engaging lesson to teach to grades 2-5. It gives the students’ knowledge on weather that we experience on Earth and makes them think beyond that to our whole solar system. They will also be challenged to create their own measuring tools to use on other planets in the......

Extreme Exploration

...Extreme Exploration By: Santiago Lopez 5-13-14 Mr. Zorfrea Grant Elementary Lopez 1 People think that extreme exploration is helpful to satisfy curiosity, but others think it’s a waste of time and money. People think that it isn’t worth the cost. I believe it’s worth a cost because there are advances in medicine, technology, and the economy. Some find medicine which leads to new technology which leads to the growth in the economic community. For example in “The Adventure of Sojourner” the rover’s battery lasted for a month. That battery could be used in earth on cars and on helicopter which helps the economy. Others find medicine to cure diseases like cancer. We conduct extreme exploration so we could find plants or herbs. In space, we could find a planet that is undiscovered could have plants and water that cures injuries and illness. In deep sea exploration we could find underwater creatures that help the economy .In “Why Exploring the Ocean Is Mankind’s Next Giant Leap” Filmmaker, James Cameron, says “A new era of ocean exploration can yield discoveries that will help in form everything from critical medical advances to sustainable forms of energy.” When people conduct extreme exploration, new technology is invented. When new technology is invented it helps the economy. In “JFK’s speech” he states that “Just as wartime development of the radar gave us the transistor (use in radios), and all that it made possible, so research in space......

Age of Extremes

...In the text, The Age of Extremes written by Eric Hobsbawn, he brings many different points and views to discussion. In the chapter ‘The Age of Total War’ (p.g22-53), he discusses how if we want to understand the world today, we have to be looking into the past of international relations and into the past wars to see how it has led to the world that we live in today. Also how it came to a world war. World War One, was a large and devastating war, which was the first war in over one hundred years to contain more than one or two major powers. Hobsbawn states that the world believed that this war was going to be the end of the world and humanity. But the world and the people survived, although the cost was great. This time was named the age of wars. He begins the chapter by describing the horrors of trench warfare and the causalities lost on both sides, The Central Powers and The Allies. Also the lasting effects that war that it can bring to the survivors. There were no peace times after the year 1914. The men and women of the time only knew peace before 1914, due to the scale of the horrors in this war. There where wars before WWI, but none to the scale, like the Crimean War 1854-56, between Russia fighting on one side and Britain and France fighting on the other side. The Crimean War only involved a few major European powers of the world. This was one of the wars which contained the most major powers until WWI when all major powers and states where involved.

Why Is Extreme Weather Difficult to Define?

...Why is extreme Weather difficult to define? Extreme weather is difficult to define because it is different for every area due to varied outlooks of the definition of “Extreme”. An area deems a type of weather extreme when it drastically shis from the weather norms, e.g. A location such as the North Pole would snow heavily, however is a common occurrence for the natives who are used to such weather. Heavy snow would be described extreme in an area such as California, or an area with more extreme heat like the desert (as it would be highly unusual for the weather to experience cold, much less having the onslaught of snow due to the hot temperatures during the year). The frequency at which certain types of weather happen, leads to how weather is perceived in that area, e.g. If heavy rainfall became common instead of rare, the weather would eventually be seen as “Regular weather,” despite being once seen as “extreme.”This makes it difficult to define because the ideas constantly change. The diagram also shows another reason why the concept of extreme weather is difficult to define, the reason being that the weather only rarely strides from the norm and even then, it is unpredictable and shows rarely any sign of impending extreme weather. There is no obvious pattern, and the graph shows this as there is only one time when the weather fluctuates so extremely. It rises above average only twice,......

Extreme Poverty and Hunger- “the Silent Killers”:

...Extreme Poverty and Hunger- “The Silent Killers”: How the World Bank plans to eradicate them by 2015 Extreme poverty and food insecurity are some of the major global issues many countries worldwide have to face. Poverty leads to heavily indebted governments, hunger, poor education and lack of adequate medical care for the people. Although poverty “is a state for the majority of the world’s people and nations (Shah, “Causes of Poverty”)”, there is hope that “the increasing interconnectedness promised by globalization (Shah, “Causes of Poverty”)” will enforce successfully global policies and practices fighting the cruel reality which over 3 billion people have to try to survive in on less than $2.50 a day (Shah, “Causes of Poverty”). Depending on how a culture views the issue with poverty, the mechanisms against it are enforced accordingly. In the middle Ages, it was considered a virtue and a way for “the chosen ones” to display their good Christian values by feeding the hungry and giving clothes to the ones who do not have any. In addition, the misery which poverty brought to the people was not considered a problem but a widely accepted path towards one’s soul salvation. In Latin America poverty used to be accepted as destiny, a family’s inheritance passed on from generation to generation. Nobody can run away from it even if one improves their financial situation because there will always be somebody to make a comment such as:” I remember whenever you were poor and had......

BPR relies on a different school of thought than business process improvement. In the extreme, BPR assumes the current process is irrelevant, does not work, or is broken and must be overhauled from scratch. Such a clean slate enables business process designers to disassociate themselves from today’s process and focus on a new process.

Extreme Sports in the Usa

...Extreme Sports in the United states of America Have you ever done something so extreme, that you've actually risked your life for it maybe? If so, why did you do it? Maybe to prove a point, but to who? Many people actually feel like they must make that impact in the world and prove a point to everyone else about being able to accomplish something maybe no one else could. It seems like a way to get attention possibly. Or maybe this just proves what people will actually do for money if it in fact was involved. It's actually said some people with personal experience to be more of a mental and spiritual thing to do, as opposed to a physical challenge, but there's no denying that you do work your legs, lung and ligaments. Everyday, daring people all over the world are participating in extreme sports like adventure racing, bull-fighting, in-line skating, bungee jumping, snow boarding and skateboarding. All of these sports involve a serious risk, and that's why they are called Extreme Sports (Now also known as action sports)wich is a general, somewhat hazily-defined term for a collection of newer sports involving adrenaline-inducing action.

Research Paper on Extreme Programming

...problem The purpose of this study is to find out if the adoption of Extreme programming in a learning environment has improved student productivity. It is a software development process used by small teams who have rapidly changing requirements. With regard to students, all students that are studying software development modules are also faced with this problem where by the requirements are continuously changing as they get deeper within their project. This paper is to show if extreme programming is actually helping students become more productive regardless of the ever changing requirements. Context or background to the research problem In this day and age the most widely used form of agile development in software development is extreme programming which was proposed by Kent Beck in 1996. Many parameters contribute to the success of XP. Researchers concluded that using XP in an educational domain has many benefits, where they have seen that less skilled students were able to show more progress than they would have if a traditional methodology were used.(Assassa, Mathkour, & Al Dossari). XP offers a number of practices, values and principles which are advised to be adopted in order to run a software development project(Assassa et al., 2006). These values include communication, simplicity, feedback and courage. Extreme programming has four stages which are planning, design, coding and testing. Extreme programming uses an object-oriented approach which has four......

The Monetary Cost Associated with Not Wearing a Motorcycle Helmet Is Extreme

...Persuasive Paper Part 1 Jo Ratliff Professor Danny Meadows English 215 November 8, 2015 The monetary cost associated with not wearing a motorcycle helmet is extreme. The loss of life is even more distressing. In recent years we have seen an increase in motorcycle accident injuries and fatalities. Head injury is the leading cause of death in motorcycle crashes. According to a government study posted on PubMed (2012), the un-helmeted motorcyclist has more severe injuries than the motorcyclist wearing a helmet. The result is longer hospital stays, possible care after the hospital and higher medical expenses (Boarini DJ, 2012). Society shares the burden with the families of the motorcyclist involved. Insurance cost increases and if the injured person does not have medical, those cost are passed on to the consumer. Before considering owning and riding a motorcycle, the risk associated with not wearing a helmet needs to be considered. The issue of whether or not to wear a helmet is extremely controversial. Some motorcyclists take an emotional stand, stating that to ride with or without a helmet is their choice. They go on to say that taking that choice away is taking away their freedom. Everyone makes choices and decisions every day. Deciding not to become another statistic by wearing a helmet is a good choice. Wearing a helmet when riding a motorcycle should be as commonplace as fastening your seatbelt before you start your car. There are always advertisements reminding......
