Fly sheets are typically made of lightweight, breathable materials that allow for air circulation around the horse's body. This can help to keep the horse cool, even on hot and sunny days.
Fly sheets are designed to provide a barrier of protection against flies and other insects, but they also serve as a sun shield, preventing the sun's rays from directly contacting the horse's skin. This can be especially important for horses with sensitive skin or those with light-colored coats, as they may be more prone to sunburn or sun damage.
However, it's important to note that fly sheets are not a substitute for proper shade and hydration. Horses should always have access to clean water and a shaded area where they can rest and cool off, especially during the hottest parts of the day.
In summary, while fly sheets can help to keep horses cool by allowing for air circulation and blocking direct sunlight, they should be used in conjunction with other measures to ensure that horses are properly cared for and protected from the heat.
