The human body temperature is maintained around 37°C (98.6°F) due to a finely tuned regulatory system called thermoregulation. This optimal temperature provides the ideal conditions for enzymes and biochemical reactions in the body to occur efficiently and effectively. In summary, the human body temperature of around 37°C represents an evolutionary balance between maximizing the efficiency […]
People get carsick or seasick (and motion sickness in general) because their brain receives conflicting messages from their sensory systems—specifically, their inner ear (vestibular system) and their eyes (visual system).
