Women who are early beginners even have twice as few risks of breast cancer as opposed to night birds that are more active in small hours and are later.
These are the results of a recent study by the University of Bristol, which involved 100 women.
Women's morning has 48% less breast cancer than women who are more active at night.
The key to everything is sleep time. Women who stay and get up early sleep sleep in the recommended schedule, which is important for the body, which is 7 to 8 hours a day.
This research only confirms that the modern way of life and the disruption of the natural cycle of sleep affects the onset of many diseases.
It is believed that a little sleep, leading to an inadequate production of melatonin, causes a lack of control of the malignant cells.
