British scientists say that women who are shown as "early awake" in biological clocks are at lower risk of breast cancer. The reason for this is still unclear, according to a team at Bristol University.
In their opinion, this finding is important because it can affect any woman at risk.
Experts say that the results of the study presented at a Glasgow Cancer Cancer Conference are the next step in confirming the importance of health for sleep as a whole.
Everybody's body has a biological clock that controls the operation in about 24 hours. It is also known as the circadian rhythm.
This affects everything – from the time we sleep to the state of mind and even the risk of a heart attack.
But not all hours are the same.

Rare people get up early, the energy reaches its peak during the day and they get tired earlier in the evening.
Other human species become more difficult in the mornings, their productivity then reaches the highest level and then prefer to go to bed.
Is this in any way related to breast cancer?
Scientists are thinking yes. They used a new way to analyze Mendel's Randomization.
They examined 341 DNA fragments that control early or night birds.
A large-scale study demonstrated the link between diet and cardiovascular disease.
He then used this information to make an experiment to about 230,000 women in a study of more than 180,000 women from the Biobanka project in the United Kingdom and the Cancer Society.
The results indicate that the probability of breast cancer disease in women who are genetically programmed for early awakening is less than that of the other group.
Since these DNA fragments are born at birth and are not associated with other known cancer factors such as obesity, scientists are reasonably sure that biologists have a finger in cancer.
How big is the effect?
One in seven women in the United Kingdom suffers from breast cancer in their lives.
However, this study concentrates only on a small period of 8 years of a woman's life.
According to this study, according to the study, 2 out of 100 patients pass late into bed and then turn into cancer, which corresponds initially to 100.

If a person fits well, does it prevent cancer?
It's not that simple.
One of the authors of the study; According to Rebecca Richmond, it is too early to offer explicit advice to women.
"We need to find out exactly what puts a group of women at risk, we need to find the link," Richmond told BBC.
Science is never 100% confident, but the results of this study coincide with other findings.
According to the World Health Organization, disruption of biological hours of people due to shift work is probably related to cancer risk.
