Part 2/8:
Many people are unaware that our body heat isn't only influenced by external environmental conditions but also significantly affected by internal processes. When we exercise, our muscles generate heat as a natural byproduct of energy expenditure. This internal heat can be substantial enough to cause heat-related injuries, even during cooler nighttime temperatures. Interestingly, scientists have developed advanced technologies, such as NASA-inspired heat absorption systems that some individuals mistakenly believe they can swallow the night before strenuous activities to reduce internal heat levels. However, the effectiveness of such approaches remains questionable, and they highlight the complex interplay of internal heat management.
