Including of light at night, even for some minutes, can lead to dangerous consequences. Scientists assert, that it is one of factors of development of cancer tumours.

Researchers from the Great Britain and Israel have found out during experiences, that light included at night provokes growth of cancer cells. The previous researches have shown interrelation between development of a cancer of a mammary gland and a cancer of a prostate and work at night at an irradiation lamps of artificial light. But now scientists confirm, what even short-term influence of night light can be bound to the raised risk of oncologic diseases.

The research group of the professor of genetics of doctor Kirjaku (university of Leicester, the Great Britain) made experiments on laboratory mice. Them subjected to an irradiation artificial light at night for a period of 1 hour. In comparison with mice which were not exposed to this procedure, at experimental group changes in brain cells were found out. Doctor Rahel Ben-Shlomo from university of Haifa (Israel) has declared, that to the people, waking up at night, it is better to abstain from light including. Any including of light influences biological rhythms of an organism and can lead to sad consequences for health.
