The wavelength of the light and the light dosage can be configured to affect a growth rate of the nail.

Methods of treating a human subject exposed to radiation in space. The methods include the steps of administering to the subject in space a chlorophyll composition sufficient to provide at least about 0.15 μM of chlorophyll or its metabolites to the subject's bloodstream, and then exposing the subject in space to light having a wavelength of about 620 nm to about 760 nm and an intensity of about 5 W/m.sup.2 to about 1000 W/m.sup.2 for at least about 5 minutes. Methods for estimating the level of ubiquinol in the bloodstream of a subject having chlorophyll or chlorophyll metabolite in the bloodstream, which may be after treatment by the above methods, include the steps of exposing the subject's skin to light to induce fluorescence of the chlorophyll or chlorophyll metabolite, measuring the level of fluorescing chlorophyll or chlorophyll metabolite in the bloodstream using fluorescence spectroscopy, and correlating the level of fluorescing chlorophyll or chlorophyll metabolite to the level of ubiquinol using a predetermined scaling factor.
