How hot does it have to get till you die?

The temperature at which heat becomes lethal varies based on factors like humidity, duration of exposure, and individual health. Generally, prolonged exposure to temperatures above 104°F (40°C) can lead to heat-related illnesses such as heat exhaustion or heatstroke, which can be fatal without intervention. Additionally, high humidity can exacerbate the effects of heat, making it more dangerous. It's essential to stay hydrated and seek shade or cooling environments in extreme heat conditions.
