The purpose of enema is for health care or treatment, depending on the purpose, the temperature is more or less different, the general situation is the temperature is 32 to 38 degrees. This temperature is less irritating to the intestinal tract, and can be used to give medicine, defecation and so on. There are some special therapeutic purposes, such as rectal weakness, which can be treated with high-temperature water, retaining the enema with 42-degree water, but it is not recommended to exceed 45 degrees. As for emergency situations, such as fecal impaction, room temperature water is feasible, but it is just not recommended to do it often. So, it depends on the purpose of the enema. Just the general temperature is enough, and the body has a mechanism to regulate it.
