Bud Winter 's Method
During World War II, the US military noticed that due to lack of sleep, fighter pilots made tragic mistakes and died. Therefore, the task of providing combat pilots with sufficient rest has become a matter of life and death.
The development and testing of the scientific method of "teaching" sleep was entrusted to Navy Lieutenant Bud Winter. In the past, he was a successful football coach and, in collaboration with a psychology professor, developed a relaxation method for athletes under stress.
Bud Winter's method has fully justified itself: after just 6 weeks of training, 96% of the pilots fell asleep within 120 seconds. Even against the background of shooting, after drinking coffee and in a sitting position.
