The assertion is false because horses that are kept in stalls do not have the same opportunities to regulate their body temperature as wild horses do. Wild horses can move to different areas, seek shade, or find cooler ground to help control their temperature in response to environmental changes. They also have the ability to graze freely, which allows them to adapt to their surroundings.

In contrast, stall-bound horses have limited movement and cannot choose their environment in the same way. Their ability to acclimate to temperature fluctuations is restricted, and they often rely more heavily on human management, such as fans, heaters, or blankets, to maintain a comfortable temperature range. These factors highlight the differences in thermoregulation between domesticated horses housed in stalls and their wild counterparts.
