Doctor urges caution when wearing a mask in extreme heat

COLUMBIA, Mo. (KMIZ)

With oppressive heat settling into Mid-Missouri, wearing a mask outdoors for too long can become dangerous.

The CDC recommends wearing a mask in order to slow the spread of COVID-19 in public places, especially where social distancing is not possible.

Dr. Christopher Sampson, an emergency doctor with University of Missouri Health Care, said staying hydrated is vital when wearing a mask outside. Wearing a mask in this heat -- highs in the 90s are predicted over the weekend -- will make it harder to breathe and easier to overheat.

Sampson has recommendations for anyone experiencing symptoms of heat-related illness.

First is to find shade, preferably indoors. Cold rags and washcloths can also be helpful to cool down those feeling ill.

Hans Overton, an organizer of a protest Friday in Jefferson City in response to the death of George Floyd, said he's gotten used to wearing a mask and urged other protesters to do the same.

Overton said he purchased water bottles and coolers to ensure demonstrators who are dehydrated or just thirsty will have access to water at all times.

Symptoms of overheating and heatstroke include extreme fatigue and a rapid heart rate.
