According to the [National Weather Service](, excess of 90°F (32°C) in felt temperature (the combination of air temperature and relative humidity) is in the danger zone for physical activity. Humidity is key here. The more moisture that’s in the air, the harder it is for your sweat to evaporate, which is what cools you down. However, for those at higher risk of heat-related emergencies (e.g., older adults, children, people with a heart condition), the temperature safety threshold may be lower than 90°F (32°C).

(You may need to start early in the day to achieve this.) - Repeat every day for at least 2 weeks, gradually exposing yourself to hotter temps. - [Hydrate adequately before, during, and after]( your workout. Note: You should only acclimatize if you already have good athletic strength and endurance.
