Abstract
We propose a "useful sun" strategy with application of a photoluminophore that absorbs a part of the UV component of the sunlight and converts it into the visible light. As a result, the "harmful" UV sun radiation becomes useful. The present study was designed to determine the effect of additional luminescent radiation with λm=626nm on the physical endurance in 12-week-old male mice. Four groups of animals were used: Control I, intact animals; Control II, exposure to standard artificial day light 5 BT/M2; Control III, exposure to solar radiation with absorbed UV-component; and Experiment, exposure to converted solar radiation with an additional orange-red luminescent component in the range of 603-637 nm (0.11 J/cm2 per day). The experimental group showed a significant increase (by more than 50%) in swimming time to exhaustion as compared to Control III. No significant difference in physical endurance was found between Control III and Control II. These results suggest that improvement in swimming endurance by the solar light is due to an additional orange-red luminescent component in the range of 603-637 nm.
