Late night shifts lead to a disrupted circadian rhythm.
Circadian rhythm is a biological process that has an oscillation of 24 hours and is activated by light.
For a person indulges in late night shifts, there has been a noticeable change in melatonin levels. Melatonin is a hormone that has a strong effect on sleep. However, its production decreases with age. It suppresses cancer cells and new blood vessel growth related to tumors. Melatonin levels tend to rise during nights; somehow, when a person stays awake at night under artificial night, the levels get decreased leading to tumor growth. Moreover, when the normal sleep cycle is disrupted, it affects the genes responsible for repairing DNA that leads to abnormal growth of cells resulting in a tumor.
