Blue light and other conditions
Constant exposure to blue light can lead to different health conditions, including:
Sleep disruption
A 2018 study showed that headache is a major cause of sleep disruption. Sleep problems can cause migraine headaches and tension, which affect your sleep cycle.
Inadequate leptin
Leptin is a hormone that becomes active after a meal to signify the presence of sufficient energy in the body. Decreased levels of leptin [1] in the blood can change your metabolism rate and increase your chances of gaining weight. A 2019 study showed that people who use devices that emit blue light have low levels of leptin.
