| An indoor tanning session is equivalent to how many hours in the sun? |
| One study seemed to indicate that based on very specific controlled factors, a single tanning session is approximately equal to two hours of outdoor sun. However, this is a very controlled study. The fact is that your tanning bed is a relatively stable source in terms of energy output. The sun is a highly unstable source in terms of ultraviolet energy output. Factors that influence the sun's UV exposure are: clouds, pollution, dust in the air, ozone levels, elevation from sea level, geography, the season of the year, and especially the time of day. |
