In order to improve the quality of recreation and life in general, engineers have attended to the task of reducing irritants during the night (light, shrill sounds, background noise, etc.). The production of equipment, machinery, motors that emanate high levels of noise is legally restricted. Architects are beginning to apply innovative materials and designs for extra noise and light blocking.
Now people sleep much less, while maintaining normal vital activity - 5.5 hours is enough for an average person. Partly, this was provided by genetic engineering, and partly – by progress in the field of medical devices and pharmaceuticals.
This, of course, does not mean that a person should disregard the importance of a good night's sleep and pleasant dreams. But the much-loathed alarm clocks can be thrown away once and for all. Go to bed after midnight and meet sunrise with a smile - easy!
