Physical temperatures outside of which two readings will start to affect physical performance?

Physical performance changes when the environment moves outside a comfortable operating range because the body has to work harder to regulate its internal temperature. The temperatures given define that boundary: 96F on the cooler side and 101F on the hotter side. Within this window, the body can usually maintain performance without excessive thermoregulatory strain. Above 101F, heat stress increases, hydration can suffer, fatigue sets in faster, and coordination can decline. Below 96F, the body’s muscles and nerves can become stiffer and less responsive, also reducing performance. So, temperatures beyond those values signal when physical performance is likely to be affected.
