Experts often suggest to have a regular sleep pattern. This suggestion is not without reason. Given regular sleep pattern will be good for your health. Conversely, if the sleep patterns messy, health can be problematic. One is the risk of breast cancer.
Irregular sleep pattern is primarily intended for employees with a working time system changes. The rhythm of sleep they were changed as a result of the system is made susceptible to cancer. It is shown from research conducted on mice.
Mice that are susceptible to the emergence of breast cancer have a body clock that is delayed up to 12 hours per week, for a year. Normally, they have a tumor after 50 weeks. But with the chaos of the regular sleep patterns, the tumor appeared 8 weeks faster. The data also indicate that the animal is more severe 20 percent, despite consuming the same amount of food.
The report, published in Current Biology says, that this is the first study to clearly show the relationship between chronic reversal light-dark with the development of breast cancer.
Although further testing on humans is still needed, the researchers say that women with a family risk of breast cancer is, you should never work with a system of rotating working time. For the record, human studies often show a higher risk for a disease such as breast cancer in workers with a system of rotating as well as flight attendants.
One explanation is that the body's internal rhythm disorders or body clock, which increases the risk of the disease. However, this relationship is vague because the type of people who work with a system of rotation can also be more likely to develop cancer due to factors such as social class, level of activity, as well as the amount of vitamin D is obtained.
One of the researchers from Erasmus University Medical Centre, The Netherlands, Gijsbetus van der Horst emphasized, "When you have a family situation with the risk of breast cancer, I would advise them not to work as a flight attendant or do work with a rotating system."
Meanwhile, Dr. Michael hastings from the UK's Medical Research Council, said he considered such research to provide definitive experimental evidence in mouse models, that disruption of circadian, or body clock, can accelerate the development of breast cancer.
The experts also emphasized, that the system is working with a rotating time have consequences. To that end, the workers would give attention to weight gain, breast health, and employers should offer more medical tests at the workplace
