According to the expert, pigeons can be called people who are less susceptible to changing sleep patterns.

“Pigeons belong to the mixed chronotype. They get up a little later than the larks and go to bed before the owls. That is, the owl is the delay in falling asleep, the lark is the early falling asleep and the early awakening, and the pigeons are the mixed type, and they are more easily adapted to the rhythm shift, ”Kalinkin said in an interview with RT.

The specialist also explained whether some sleep patterns are really harmful to human health.

“It is believed that owls have a certain predisposition to the development of various diseases. But these are observational studies with low scientific value. In any case, we know that sleep, which is maximally conjugated with the dark time of day, is the most optimal for a person. Therefore, the more it shifts with respect to the dark time of the day and the more it moves towards daylight, the worse, ”he noted.

Earlier, somnologist Alexander Palman told how many hours of sleep are needed in order to sleep.
