Kirutan

Kirutan, also known as Kiru Tan or Kiru-Tan, is a Japanese term that translates to "needle tan" or "needle sunburn." It refers to a unique and temporary skin condition that occurs when an individual spends an extended period of time in direct sunlight while wearing a swimsuit with thin straps. The thin straps of the swimsuit block the sun's ultraviolet (UV) rays from reaching the skin underneath, while the surrounding skin is exposed to the sun. This creates a contrast in skin color, with the areas under the straps remaining lighter while the rest of the skin tans, resulting in a distinctive pattern.

The term "kirutan" is derived from the Japanese words "kiru" (to cut) and "tan" (tan or suntan). The condition is often associated with the summer season in Japan, when people engage in various outdoor activities and beach trips. Kirutan is not a medical condition but rather a cosmetic effect of sun exposure. However, it is essential to note that prolonged exposure to the sun without adequate protection can lead to sunburn, skin damage, and an increased risk of skin cancer.

To prevent kirutan and protect the skin from harmful UV rays, it is recommended to apply a broad-spectrum sunscreen with a high sun protection factor (SPF) before sun exposure. Additionally, wearing a wide-brimmed hat, sunglasses, and protective clothing can help minimize the risk of sunburn and other sun-related skin damage. It is also advisable to seek shade during peak sun hours, typically between 10 a.m. and 4 p.m., to reduce the intensity of UV exposure.
