Sleep disturbance increases the risk of cancer and leads to excess weight

Lack of sleep or irregular sleep may cause a variety of ailments. Excessive sleep is also harmful, especially in middle age. New research has shown a high risk of cancer for those who have trouble sleeping.

In the study, it was discovered that poor or irregular sleep has led to the development of cancer in mice. These results confirm serious concerns about the impact of shift work on human health, reports the British news service Bi-bi-si.

The researchers also suggested that women with a family history of breast cancer should avoid shift work, which leads to disruption of sleep. However, final conclusions can only be made after additional studies, the researchers note.

The researchers delayed the biological clock of mice at 12 hours each week during the year. As a result, rodents with disturbed circadian rhythm, the tumor evolved for eight weeks earlier than usual. In normal mice with the gene mutation, breast cancer develops in 50 weeks.

The study also showed that irregular sleep can lead to weight gain. Animals with sleep disorders have become 20 percent heavier, although they consumed the same amount of food as mice with a regular regime.

The researchers note that the violation of the biological rhythms may be the cause of increased risk of developing various diseases.

The study was published in the scientific journal Current Biology. published
