Some people just aren’t bothered by the cold, no matter how low the temperature dips. And the reason for this may be in a person’s genes. Our new research shows that a common genetic variant in the skeletal muscle gene, ACTN3, makes people more resilient to cold temperatures.

Around one in five people lack a muscle protein called alpha-actinin-3 due to a single genetic change in the ACTN3 gene. The absence of alpha-actinin-3…
