The last one of the authors (J.F.), an older woman, living in the state Tennessee, USA, has observed since long time a considerable decrease of her vigor, the feeling of exhausting, weariness etc. These episodes start usually on the beginning of summer and winter and last about two months. Following the recommendation of specialists she recorded every day in 2009/2010 the level if her vigor using a special index. The series of these whole year data displays as a most striking phenomenon a clear semiannual wave with sharp minima. However, their position does not correspond to solstices or equinoxes. Its annual course displays no similarity with the solar or geomagnetic activity. It seems that the period of decreased vigor starts always in the days with extremes in air temperature, i.e., in hot and cold days. This hypothesis is supported by the fact that deviations of the air temperatures from the normal annual course correspond well with the changes in vigor.
