Bb5a31f81ClaimJustin Mares undergoes a coronary calcium scan roughly every 18 months to assess arterial calcium buildupAgreeDisagree
Bb5a31f81ClaimA Second World War study that exposed conscientious objectors to freezing conditions and cold showers found no increase in cold infection ratesAgreeDisagree
Bb5a31f81ClaimWalking in cold ambient wind in shorts and a T-shirt stimulates the sympathetic nervous system and activates brown adipose tissueAgreeDisagree
Bb5a31f81ClaimThe cold shock response triggers a gasping reflex that causes hyperventilation and an increased breathing rate in unadapted individualsAgreeDisagree
