Impact & Risks

The extreme heat poses a significant risk to vulnerable populations, including the elderly, children, and those with pre-existing health conditions.

Outdoor workers and individuals without access to air conditioning are particularly at risk. The oppressive humidity further exacerbates the danger, making it harder for the body to cool down naturally.
