Doctor Leshchenko: on cloudy days, a headache may occur due to a lack of light 
NI Pirogova, candidate of medical sciences and ophthalmologist Irina Leshchenko explained why a headache occurs on cloudy days. She spoke about the influence of bad weather on a person's condition in an interview with Sputnik radio.
According to the expert, the level of illumination sharply decreases on cloudy or foggy days. Lack of light adversely affects the eyes and often leads to headaches. “Everybody has his own signs of eye fatigue, for example, I get drowsy. That is, the eyes want to sleep, not the head: when you lie down, they close, and the brain continues to work actively. Tired eyes constantly want to rub, scratch. You may also experience pain in the eyes or in the head, “Leshchenko said.
The ophthalmologist advised to turn on the light more often in cloudy weather, regardless of the time of day. “Artificial lighting is turned on to make it more comfortable for the eyes. A computer or gadgets have backlighting, but still it is not very pleasant for the eyes if the room is dark and the light source is one device, ”the expert noted.
