Getting out of the warm blanket feels like a mammoth task during winters and we often tend to become lazy during the chilly weather. Have you ever wondered why?
According to Oxford Sparks, the circadian sleep cycle in our body is programmed to tell us when to sleep and when to wake up. Humans mostly sleep when it is dark and there’s no sunlight and remain active during the day. So, as winters have shorter days and longer nights, we often get more lethargic during this season.
