One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
