Fans may raise body heat rather than cool it under certain conditions. As outdoor temperatures climb, running a fan can deepen heat stress instead of relieving it.
The ideal point to stop using fans depends largely on humidity levels. High humidity reduces evaporative cooling, making fans less effective or even counterproductive.
Age also impacts how fans affect personal comfort. Older individuals can respond differently to heat and airflow, requiring tailored cooling strategies.
These factors highlight the need to consider personal and environmental conditions when deciding whether to use fans for safe cooling in hot weather.
