Final answer:
It is advised to avoid sun exposure between 10 am and 2 pm to reduce the risk of sunburn and skin cancer, while still acknowledging the benefits of sun exposure for vitamin D synthesis (c).
Step-by-step explanation:
The precaution that is advised regarding sun exposure is 'I should have my child avoid sun exposure between 10 am and 2 pm.' This time frame is when the UV radiation from the sun is the strongest, which can lead to immediate skin damage such as sunburn and increase the long-term risk for skin cancer. While vitamin D synthesis, important for bone health, occurs with sun exposure, it's beneficial to balance sun intake with protective measures. Regular application of sunscreen with an SPF 30 or above, seeking shade during peak hours, and wearing protective clothing can greatly reduce these risks.
Vitamin D synthesis is required for health and while some sun is beneficial, too much can be harmful. Sunscreen acts as a barrier to protect against the harmful UVB radiation responsible for skin damage and can enable safe exposure to the sun for vitamin D production
