How extreme heat can affect your health

These extreme temperatures not only take a toll on the environment, but also on your health.

Driving the news: The heat in NWA isn't letting up any time soon. We continue to be under a heat advisory Friday, according to the National Weather Service, and you can expect highs to stay in the 90s and even up to 100 in the coming weeks.

Threat level: Extreme heat is increasingly taking a toll on children, pregnant people and other vulnerable populations, and children will experience 35 times more life-threatening extreme heat events than kids born about 60 years ago, Axios' Arielle Dreher writes.

Zoom in: The state Department of Health warns that Arkansans can prevent heat-related illnesses by drinking water often, wearing sunscreen and loose-fitting clothing, and avoiding unnecessary sun exposure and strenuous outdoor work.
