The process helped revolutionize agriculture by providing ...

Here’s how extreme heat affects sleep — and how to cool down at bedtime. ... the effects could cause people to lose between 50 and 58 hours of sleep per person each year by the end of the century.
Many scientists have taken inspiration from the bunker experiment, performing a myriad of studies on the human circadian clock.
