What should be the minimum temperature for indoors in areas with extreme heat?

The minimum temperature indoors in areas with extreme heat should be set at 68 degrees. This guideline aligns with recommendations for maintaining a comfortable and safe indoor environment during high-temperature conditions. Maintaining a temperature around this level helps prevent heat-related illnesses and ensures that individuals, particularly vulnerable populations such as the elderly or those with medical conditions, remain cool and comfortable.

Setting the indoor temperature too high can lead to heat stress, dehydration, and other heat-related health issues, especially in populations that are more susceptible to high temperatures. While some may argue for slightly higher indoor temperatures, the 68-degree threshold is established as a safe compromise to balance comfort and health needs.
