Surveys have revealed that richer populations tend to be more well-rested.
Prime Minister Narendra Modi is said to work 20 hours a day. "I have very little sleep. All my doctor friends consistently advise me that I should increase my sleeping. I should sleep minimum for 5 to 6 hours. But I have become so workaholic and it has become my habit since many years that I hardly sleep for 3.5 hours. But it is a very sound sleep. I go to bed and within 30 seconds I fall asleep," PM Modi said during an interview in 2011.
Former US President Donald Trump makes do with four hours of sleep. Apple CEO Tim Cook is up before 4am.
However, not everybody has busy schedules like that of world leaders which leaves them with more time to catch up on much-required sleep. Worldwide, physical and mental health experts stress on the importance of a good night's sleep for a healthy functioning of body and mind, which in turn has a bearing on productivity and capacity to work harder.
The National Sleep Foundation, an American institute, says adults need seven to nine hours a night. Sleeping lesser can cause harm not only to yourself but to others around you as well. 20 hours of wakefulness has the same weakening effect on reasoning and reaction times as drinking a bottle of wine. Two weeks of six-hour nights slows your brain as much as two consecutive nights of no sleep; doing so consistently increases your chance of an early death by 13%.
People in most rich countries tend to be well-rested, suggesting that a good dose of sleep is a luxury. In rapidly growing economies such as Taiwan and South Korea workers turn in at 1am on an average night. Many of those in Islamic ones have early morning prayers. Such fatigue can debilitate an economy. Japan is the weariest nation of all: a 2016 study found that exhaustion cost it nearly 3% of its annual gdp, largely by lowering productivity.
