3. Environment

You also need to think about your environment, the kind of weather and climate that you experience regularly. If you live in a colder climate, you can get away with showering less. Over-showering in a super dry climate might prove to dry your skin out even more. Conversely, hot and humid climates lead to you sweating more and more, which obviously requires showering in order to get rid of toxins and bacteria that have appeared on your skin.
