In an interesting TED talk, Russell Foster explain why it’s a myth that we all need 8 hours sleep a night. He also claims that people who boast about getting up early in the morning are simply ‘smug’!
Foster explains the neuroscience behind why sleep deprivation can also lead to being overweight with poor problem solving skills and lack of judgement.
Think again, if like former British PM Margaret Thatcher, you believe that sleep is for wimps!
