What are the functions of the skin and how do they contribute to overall health and well-being?

The skin serves as a protective barrier against harmful substances, regulates body temperature, and helps to prevent dehydration. It also plays a role in immune function and sensation. These functions contribute to overall health and well-being by protecting the body from infections, maintaining proper body temperature, and allowing us to sense our environment. Taking care of the skin through proper hygiene and skincare routines can help maintain its functions and promote overall health.
