Acclimatization | Heat | CDC - Centers for Disease Control and Prevention Acclimatization is the beneficial physiological adaptations that occur during repeated exposure to a hot environment These physiological adaptations include: Increased sweating efficiency (earlier onset of sweating, greater sweat production, and reduced electrolyte loss in sweat)
Heat Stress: Acclimatization - Centers for Disease Control and Prevention Acclimatization New employees are at the highest risk for heat illness Acclimatization is crucial to working in hot conditions : • • • Photo by NIOSH What are the benefits of heat acclimatization? • Heat exposure causes less strain to the heart and other vital organs • Sweating improves (higher volume, earlier onset), which
High-Altitude Travel and Altitude Illness | Yellow Book | CDC Some acclimatization to high altitude continues for weeks to months, but the acute process, which occurs over the first 3–5 days following ascent, is crucial for travelers The acute phase is associated with a steady increase in ventilation, improved oxygenation, and changes in cerebral blood flow

Protect Your Workers from Heat Stress - CDC Develop an acclimatization plan Acclimatization is the result of beneficial physiological adaptations (e g , increased sweating efficiency and stabilization of the circulation) that occur after gradual increased exposure to a hot environment Tip 1 Gradually increase exposure time in hot environmental conditions over a 7–14 day period Tip 2
stress Overview - Centers for Disease Control and Prevention Acclimatization is critical, and may need to be repeated! • Heat acclimatization is the improvement in heat tolerance that comes from gradually increasing the duration or intensity of work performed in a hot setting • Acclimatization is most effective if it takes place • You begin to lose your acclimatization after about
Heat Illness and Death Among Workers — United States, 2012–2013 Acclimatization is the result of beneficial physiologic adaptations (e g , increased sweating efficiency and stabilization of circulation) that occur after gradually increased exposure to heat or a hot environment (3) Whenever a potential exists for workers to be exposed to heat or hot environments, employers should implement heat illness
