How often can a member use tanning services?

A member can use tanning services once every 24 hours because this policy is designed to ensure the safety and health of the members while using tanning equipment. Tanning involves exposure to UV light, and limiting usage to a 24-hour window helps prevent overexposure, which can lead to skin damage or increase the risk of skin cancer. This frequency also allows members to adequately hydrate and care for their skin between sessions.

The other options suggest frequencies that do not align with health guidelines for tanning. For instance, allowing tanning every 12 hours would not provide sufficient time for proper skin recovery, while once per week might not cater to members looking for more regular tanning sessions in a shorter timeframe. The selection of once every 48 hours is also more extended than the recommended 24-hour interval, which could lead to missed opportunities to utilize the service more frequently without compromising health standards.
