Abstract

Changes in hormone levels in the blood of the male population of Arkhangelsk (22 to 45 years old) were observed at various weather conditions and magnetic field strength of the Earth. We found a significant responsiveness of the endocrine system to the temperature, especially at negative temperatures, as well as in case of positive and negative temperatures being combined with high air humidity (> 85 %). At average geomagnetic disturbance (Ap = 30–50 nT) we revealed elevated blood levels of adrenocorticotropin, testosterone and decreased concentrations of triiodothyronine. The paper shows the dependence of the levels of cortisol, triiodothyronine and testosterone in the blood on such factors as day length, temperature and relative humidity, barometric pressure, and Ap-index. The main factors affecting the levels of cortisol and T3 in the blood are day length and air temperature; the most significant factor for testosterone level is temperature, followed by relative humidity and day length.
