During the summer, outdoor heat in Orange County, CA can be so excruciating that you simply can’t wait to get home and turn the AC on at full blast. Experts, say, however that this is a bad practice.
Abrupt temperature changes, like entering an extremely cold room after a hot day outside can be harmful to the health, because it subjects the body to a certain level of stress. When you are exposed to extreme temperatures, your body naturally regulates itself to maintain your core temperature. Sweating when it’s hot, and shivering when it’s cold, are both natural thermoregulation techniques that our bodies do. A rapid change in temperature will throw this process into chaos, since the body will be forced to abruptly adjust to the new temperature. This is especially true when you enter an air-conditioned room while sweaty because the water (in the form of sweat) could instantly cool, making it feel like ice.
