Humans are photoperiodic, as are all mammals. As our modern environment severely alters the natural photoperiod our physiology is negatively impacted.
Are there any humans whose environment does not severely alter the natural photoperiod, with physiology not (much) negatively impacted? For example, there are still a few million who live a life of hunting and gathering, and a few more million in nomadic herding.
