Acclimatization

Implications • Climate is the biggest single factor affecting animal production. • Acclimatization is a coordinated phenotypic response to environmental stressors and the response will decay if the stressors are removed. • Acclimatization occurs in two phases; short term (acute stress response) and long term (chronic stress response). • The acute phase acclimatization response is under homeostatic regulation and the chronic phase response is under homeorhetic regulation. • If chronic stress persists over several generations, the acclimatization response will become genetically “fixed” and the animal will be adapted to the environment. Introduction Climate is the most important ecological factor determining the growth, development, and productivity of domestic animals ( Despite uncertainties in climate variability, the Intergovernmental Panel on Climate Change ( IPCC) Fifth Assessment Report identified the “likely range” of increase in global average surface temperature between 0.3 °C and 4.8 °C by the year 2100 ( Nationally, heat stress results in total economic losses ranging between $1.9 and $2.7 billion per year ( Our understanding of the mechanisms by which environmental stress reduces productivity of domestic animals has greatly improved over the last century ( Therefore, improving productivity in animals exposed to adverse environmental conditions during the last quarter century focused on modifying the environment and improving nutritional management while applying ...

Acute altitude illness comprises acute mountain sickness (AMS), high altitude cerebral edema (HACE), and high altitude pulmonary edema (HAPE). Symptoms of AMS, the most common form of altitude illness, include headache, nausea, vomiting, fatigue, dizziness, and insomnia. If not appropriately treated, AMS can progress to life-threatening HACE or HAPE, which can present together or separately. Although HACE presents with similar symptoms as AMS, the cerebral edema can lead to ataxia, confusion, or altered mental status. HAPE is characterized by reduced exercise tolerance, exertional dyspnea, and cough, followed by dyspnea at rest, cyanosis, and productive cough with pink frothy sputum. Unacclimatized people are at high risk of acute altitude illness when ascending above 8,200 ft (2,500 m), but AMS can occur as low as 6,500 ft (2,000 m). HACE is typically encountered at higher elevations unless presenting with HAPE. The Wilderness Medical Society does not use specific altitude thresholds for diagnosis. People without a history of AMS who do not sleep above 9,200 ft (2,800 m) are at low risk of AMS. Regardless of AMS history, people who allow at least two days to ascend to a sleeping altitude of 8,200 to 9,800 ft (2,500 to 3,000 m) are at low risk if they sleep no more than 1,600 ft (500 m) above the previous night's altitude and take a day to acclimatize after every increase of 3,300 ft (1,000 m) in sleeping altitude. People with a history of AMS who make a one-day ascent to ...

It doesn’t take a trip up Everest to begin to feel the effects of higher altitudes. A visit to one of your favorite mountain destinations can be enough. However, with proper preparation and understanding of how to acclimate your body appropriately and spend time at altitude , as well as what the signs and symptoms of What is Acclimatization to High Altitude? Acclimatization is the process of allowing your body to adapt to higher altitudes. Specifically, this applies to decreasing oxygen in the air as you go higher. If possible, ascend gradually to give your body sufficient time to adapt. A prominent school of thought is that people should not ascend from a low elevation to more than 9,000 feet (2,750 m) sleeping elevation in one day. Once above 9,000 feet, ascend no higher than 1,600 feet (500 m) sleeping elevation per day and plan an extra day for acclimation every 3,300 feet (1,000 m). The High Altitude Acclimatization Process PREPARATION STAGE If you’re planning an upcoming visit to Aspen and the Roaring Fork Valley, consider spending your first night in Colorado in Denver. The Mile High City is still about 3,000 feet lower than Aspen, which sits at an elevation of 8,000 feet. Spending one night in Denver’s 5,280-foot elevation will help your body adjust before you head higher. Once you arrive in Aspen, it’s worth taking it easy for the first day or two. Over exerting yourself right off the bat might mean you spend the rest of your visit trying to recover. ASCENT STAGE ...
