Observations made in warm-blooded prove that the reduction of ambient temperature and secondary of the body emerge real opportunities to increase life expectancy not only in animals but also in humans. In reducing the calorific value of nutrition and retention of the necessary components, increased life expectancy is accompanied by lowered body temperature. Restricted diet is therefore one of the physiological processes for reduction of body temperature. In parallel, it is one of the modern ways of extending life expectancy.
Large doses of exposure to ionizing radiation can significantly reduce life expectancy. At the exposure to low doses of ionizing radiation which is fed in for long periods of time can be observed increased longevity. Experimental gerontology demonstrates that positively charged electric field adversely affects the body, on the contrary, the impact of the negative electric field is advantageous and increases life expectancy.
Of all the elements studied only 3 valence chromium, palladium and yttrium caused a significant increase in life expectancy.
