Humans can overheat if core body temperatures much above 98.6 ° F (37 ° C) are sustained.16 Normally, when skin temperatures is somewhat cooler than 98.6 ° F (37 ° C), the body loses its metabolically generated heat by conducting that heat outward from the core.7
Extremely hot and
humid conditions, however, can make it difficult to keep this heat balance maintained.16 Extreme heat can be particularly dangerous to old, young, or frail people; to those suffering from cardiovascular, respiratory, or diabetic disease; and to lower - income people who do not have well - insulated homes or air -

This
extremely hot, near 90 degree water, has formed the central pulse of the current heatwave even as it has pumped extraordinarily
humid air for such hot
conditions over adjacent land areas.»
