What is meant by the phrase the tanning myth?

The phrase "the tanning myth" refers to the misconception that a suntan is a sign of good health or a protective barrier against sun damage. In reality, tanning is a response to skin injury caused by ultraviolet (UV) radiation, which increases the risk of skin cancer and premature aging. The myth perpetuates the idea that tanning is safe or desirable, despite the well-documented harmful effects of UV exposure.
