How can comfort levels be improved in the cooling season at higher temperatures?

Explanation:
Improving comfort levels in the cooling season at higher temperatures can be effectively achieved by removing humidity and increasing air velocity. High humidity levels can lead to discomfort because it interferes with the body’s ability to cool itself through the evaporation of sweat. When humidity is high, sweat does not evaporate efficiently, making the environment feel warmer than it actually is. By removing humidity, the air feels drier, and this enhances the body's cooling process, leading to a more comfortable environment. Additionally, increasing air velocity augments the wind chill effect, which also contributes to comfort. The movement of air across the skin helps accelerate the evaporation of moisture, further promoting the cooling sensation. Enhancing comfort in high-temperature situations relies significantly on these two aspects—humidity control and air movement—because they directly impact how the human body perceives temperature and comfort. In contrast, options like increasing air pressure or adding humidity would not be effective for improving comfort under hot conditions, and simply lowering the thermostat may not sufficiently address the perceived heat caused by high humidity levels.
