Another study that analyzed adolescents using their mobile phones or gadgets during the night found that only one hour of exposure to blue light reduced melatonin levels by 23%. In two hours, it was further reduced to 38%.

Melatonin has anticancer properties and low levels at night can increase the risk of cancer. In one study, women who worked night shifts had low levels of melatonin and a 50 to 75% higher risk of developing breast cancer in their lives.
People who are exposed to blue light at night have a lower level of insulin production. This means that the snacks that you eat when you get up late do not break down into glucose and the body uses them. Instead, they become fat and increase body weight.
