	Acclimatization - Wikipedia, the free encyclopedia
		It is a common misconception that acclimatization and acclimation are synonymous.
		This may be a discrete occurrence or may instead represent part of a periodic cycle, such as a mammal shedding heavy winter fur in favour of a lighter summer coat.
		Where acclimitization occurs naturally, in the field of physiology acclimation is used to describe the process of an organism being forced to adjust to changes in their environment by artificial means, such as in a laboratory setting (Schmidt-Neilsen 1990).

		In the case of the latter class, however, acclimatization is a necessary preliminary to naturalization, and in many cases to useful domestication, and we have therefore to inquire whether it is possible.
		Acclimatization by Individual Adaptation.It is evident that acclimatization may occur (if it occurs at all) in two ways, either by modifying the constitution of the individual submitted to the new conditions, or by the production of offspring which may be better adapted to those conditions than their parents.
		Acclimatization by Variation.A mass of evidence exists showing that variations of every conceivable kind occur among the offspring of all plants and animals, and that, in particular, constitutional variations are by no'means uncommon.

	Acclimatization
		acclimatization) is the process of adaptation by which animals and plants are gradually rendered capable of surviving and flourishing in countries remote from their original habitats, or under meteorological conditions different from those which they have usually to endure, and which are at first injurious to them.
		In the case of the latter class, however, acclimation is a necessary preliminary to naturalization, and in many cases to useful domestication, and we have therefore to inquire whether it is possible.
		The best examples of partial or complete acclimatisation are to be found where European races have permanently settled in the tropics, and have maintained themselves for several generations.

	SSE #65: Preparing Athletes for Competition in the Heat: Developing an Effective Acclimization Strat (Site not responding. Last check: 2007-11-03)
		Acclimatization is most effectively achieved by exercise in the heat; heat without exercise and exercise without heat are less effective.
		An ideal approach to acclimatizing athletes to the heat may be a combination of increasing the level of heat exposure at home during the last 1-2 weeks before traveling and a well-designed heat-acclimatization program at the new site.
		The acclimatization process requires the athlete to be exposed to sufficient heat stress for the necessary adaptations to take place, but there is a real danger that taking the process too far or too quickly can result in heat injury.

	The Physician and Sportsmedicine: Keeping Sports Participants Safe in Hot Weather
		Acclimatization is the process of physiologic and psychological adaptation to a new environment, such as when a person moves from a cool climate to a hot climate or simply adjusts from spring to summer.
		Many of the physiologic benefits of heat acclimatization are similar to those of physical training: reduced heart rate, core temperature, and utilization of muscle glycogen, as well as increased cutaneous blood flow, plasma volume, red-cell filterability, and work time until exhaustion (2,3).
		Acclimatization typically requires 10 to 14 days in the warmer environment, but 75% of the adaptation is believed to occur within 5 days (4).

		There are no medicines that guard against acclimatizing to the altitude, and fitness is not a substitute (sometimes fit youngsters tend to have more problems).
		Acclimatization is an inevitable and normal process that takes different timing on every individual.
		It takes about 5 months living at the high altitude for the body to become completely acclimatized (actually it takes 3 generations to get fully acclimatized, so if you decide to live at high-altitudes, your grandchildren will be born with high altitude physiological adaptation).

	EFFECTS OF CHANGES IN STRATOSPHERIC OZONE AND GLOBAL CLIMATE
		Acclimatized rates were computed by selecting present-day "analog cities" which resemble New York's predicted future weather and by developing weather/mortality algorithms for them.
		We suggest that a lag in acclimatization to climatic change is likely, and factors such as the physical composition of the city (i.e., building construction designed to accommodate present weather conditions) will delay or prevent full acclimatization.
		Using the algorithms for no acclimatization, this proportion is predicted to rise significantly as the weather warms, and since the deaths are standardized, this does not assume that the elderly will constitute a larger proportion of the population in the future.

	OA Guide to High Altitude: Acclimatization and Illnesses
		This process is known as acclimatization and generally takes 1-3 days at that altitude.
		Acclimatization is often accompanied by fluid loss, so you need to drink lots of fluids to remain properly hydrated (at least 3-4 quarts per day).
		The acclimatization process is inhibited by dehydration, over-exertion, and alcohol and other depressant drugs.

	Human Biological Adaptability: Overview
		The difference between the kinds of acclimatization is not only in the amount of time it takes for the adjustment to initially occur.
		Acclimatization occurring in childhood may result in permanent anatomical changes, as is often the case with malnutrition.

	Acclimatization of Ficus benjamina: A Review
		Ficus benjamina and its cultivars have been the focus of much of the foliage plant acclimatization research for the past 20 years because of their enormous popularity with the plant buying public and also because weeping figs are among the sun-shade plants most clearly benefiting from the acclimatization process.
		High quality acclimatized plants were grown under shade in less time than the previously accepted acclimatization method of growing plants under full sun before subjecting them to an acclimatization period under low light.
		Acclimatization also affected respiration rate and as a plant became fully acclimatized respiration rate declined dramatically which reduced carbohydrate requirements.

	Pardoes Altitude & Acclimatization Page
		A general discussion of the problems of high altitude is followed by a section on the process of acclimatization.
		Acclimatization in this context means the deliberate, temporary modification of the response of the human body to increased altitude.
		The extent to which a formal and managed acclimatization programme is required on any climb depends on the absolute altitude, the overall altitude gain, and especially on the amount of time for which it is planned to stay high [1].

		The residence and the rest in the base camp 1 or 2 days renew your strength and secure a gained acclimatization keeping a certain balance between acclimatization and deterioration-the exhaustive emaciation of the organism, although a mountain-climber will never reach the level of his capacity for work in the plain conditions.

	Altitude Training
		Acclimatization is appropriate for a relatively short period of exposure, such as when athletes are taken to an "altitude" camp for a month.
		Since altitude acclimatization is a different stress to exercise stimulation, one should expect little transfer of the effects of altitude acclimatization.
		Acclimatization to altitude occurs slowly and exercise quantity, and often quality, has to be reintroduced gradually.

		Acclimatization is the process of the body adjusting to the decreasing availability of oxygen.

		But it is no substitute for drinking huge amounts of water, acclimating slowly, being in good shape (no one knows if this helps, but it is not likely to hurt), and paying good attention to your body.
