In the wild, they do, yes; it's an activity called grazing. Domestic horses confined to stables, barns or drylots with no grazing area don't have this opportunity. It is primarily seen as a social and behavioural activity for horses; for one, it keeps the horse from being bored, it is a social bonding experience and activity, and it some how keeps a horse from acquiring stereotypical behaviour disorders like that seen in horses that have been confined for a long time. It is natural for a horse to be grazing at least 8 to 12 hours a day. Horses that do not have this opportunity develop stereotypies such as wind-sucking, weaving, pacing and cribbing because they are denied their natural behaviour and activity of grazing with their herd mates all day.

A horse can have as big area for grazing just don't make it too small. I keep my horses in about 1-2 acres and my horse is healthy.
Horseracing. Without the horse the jockeys would look a little silly.
Riding a grazing horse is not advisable, as it can pose safety risks for both the rider and the horse. Horses that are grazing may not be fully attentive or responsive to commands, which can lead to unpredictable behavior. Additionally, the horse may not be properly warmed up or in the right mindset for riding. It's best to ensure the horse is in a suitable state for riding before mounting.
Sweating. A horse sweats to keep cool. The horse has the same cooling mechanism that humans do.
On average, a horse typically requires about 1 to 2 acres of land for adequate grazing and exercise.
A graze just above a horses hoof.
