Sleep discrimination

A recent study (1) concludes that the world is heading toward sleepless nights with climate change driving temperatures up. A mere 1 degree temperature rise at night could result in a 10% loss in sleep. This is a problematic trend, with a skewed impact on the poor who can't afford air conditioning. More importantly, loss of sleep has significant deleterious effects on health and cognition, with possible broad impacts on students and young adults. This is another reminder that changes in the environment could have negative effects on the population in many different ways. Anything that affects the rapid progression of millennials is not something humanity could afford, at this critical juncture, if they were to leap to a level 1 society.

As they ventured out of Africa, humans encountered harsh winters in the North with their systems adjusting rapidly by changes in skin and hair colors. Those who went South had an easier time and appear to be well positioned for the rising temperatures of the modern world. However, the organ they carry on their shoulders hogs energy and has to be kept cool for them to slumber. A rise in the ambient temperature is problematic for the human system and especially for the CPU. Perhaps, it is time for newer technologies that let a cooler bubble around the human brain. Evolution of the human brain has been slow. Massive leaps achieved a few hundred thousand years ago by animal fat have been tempered significantly by the advent of agriculture. And, modern humans appear to show slow degradation of cognitive capabilities, perhaps aided by substance abuse.

It is unlikely that humans can turn back the temperature dial but perhaps they can find more creative ways to cool the brain cells and sleep better.
