Sleep trivia: Mrs. Thatcher only sleeps 4 hours a night?

Former British Prime Minister Margaret Thatcher is well-known: She only needs to sleep 4 hours a night to work normally. Someone once heard her husband Dennis yelling: “Woman, go to sleep!” .

Her “predecessor” Winston Churchill only slept 4 hours a night during the war. Supporters of both may proudly say: “This is because they are both passionate about work!”

However, new research found that the two former prime ministers both took advantage of their genes.

Scientists at the Center for Applied Genetics in Philadelphia found that those who carry the “p.Tyr362His” gene variant can work normally with less than 5 hours of sleep per night.

In the case of not sleeping for 38 consecutive hours, their mental condition is much better.
