Heat is crucial in most bodily functions and cognitive processes, but too much heat can impair alertness, attention, and even emotion, as may be seen in cases where exposure to high temperature has incited aggression and irritation. If the body isn't able to regulate heat intake, it can result to heat stroke and exhaustion. As a responsible employer or manager, you will need to make sure that your employees arenâ¤™t subjected to too much heat, particularly in the summertime, when California temperatures can hit extreme highs. It is important to ensure that Ontario or Rancho Cucamonga air conditioning units are working optimally. This is particularly true in manufacturing facilities, where machineries can further increase the level of heat.
