PHYSICAL WELLNESS

your body’s protective layer


SKIN


Your skin is the body’s largest organ and first line of defense. It acts like a strong but flexible barrier, keeping harmful things out and essential things in, while also helping regulate temperature and allowing you to feel the world around you.

  • Protects against germs, chemicals, and physical injury

  • Prevents excess water loss and keeps fluids balanced

  • Helps regulate body temperature (through sweat + blood flow)

  • Produces vitamin D when exposed to sunlight

  • Allows you to sense touch, pressure, heat, and pain
