How cold affects muscles, blood flow, and cardiovascular risk—plus practical ways to keep moving safely indoors and out.

Biomechanist Katy Bowman and biologist Dr. Jeannette Loram explore how cold air and cold water affect muscle function, blood flow, heart rate, and blood pressure during exercise. They unpack how vasoconstriction increases cardiovascular demand, and why activities like snow shoveling and cold-water swimming carry specific risks. The episode also offers practical strategies for continuing to move safely outdoors throughout the winter months.

Even when winter keeps many of us indoors, movement doesn’t have to disappear. Karri Bowen-Poole of Smart Playrooms joins Katy to discuss how indoor spaces can be designed to encourage movement for kids, teens, and adults. They share ideas for simple, versatile equipment that supports strength, coordination, and play, explain why visible and aesthetically pleasing setups matter, and describe how rotating movement tools over time helps sustain interest as needs and abilities evolve.
