What is the primary function of a tanning bed's reflector?

The primary function of a tanning bed's reflector is to increase the intensity of UV radiation delivered to the skin. Reflectors are designed to bounce UV light back towards the tanner, maximizing the amount of ultraviolet exposure the skin receives in a shorter amount of time. This amplification of light can enhance the tanning process, allowing users to achieve a deeper tan with potentially fewer sessions.

The other options specify functions that do not accurately represent the role of reflectors in tanning beds. Monitoring skin temperature is more related to safety mechanisms rather than the tanning process itself. A cooling effect is not associated with reflectors, as their purpose is to enhance heat and light intensity. Lastly, while some tanning beds may have filters to block harmful UV rays, reflectors do not serve this function; in fact, they primarily aim to intensify the UV light.
