Final answer:
The full effects of UV exposure can vary depending on the individual and the intensity and duration of the exposure. In some cases, immediate effects like sunburn can occur, while long-term effects like skin cancer may not appear until years later. Protecting yourself from UV exposure is important.
Step-by-step explanation:
The full effects of UV exposure can vary depending on the individual and the intensity and duration of the exposure. In some cases, the effects of UV exposure can be immediate, such as sunburn. However, for the long-term effects of UV exposure, such as skin cancer or the development of cataracts, it can take years or even decades for these effects to become apparent.
For example, it requires about 10 days after initial sun exposure for melanin synthesis to peak, which is why pale-skinned individuals tend to suffer sunburns of the epidermis initially. On the other hand, the long-term effects of skin cancer may not appear until years later.
It is important to protect yourself from UV exposure by wearing sunscreen, protective clothing, and sunglasses, and by seeking shade during peak sun hours.
