We spend 1\/3 of our lives dozing<\/strong><\/b>. Yet sleep quality and mood are deteriorating: on average, people sleep 1h30 less than they did 50 years ago<\/strong><\/b>. Stressful work and the omnipresence of screens whose blue light delays sleep are directly incriminated. For example, 30 lux lighting (computers, tablets and phones) delays sleep by 77 minutes, and direct lighting by 109 minutes.<\/p>\n <\/p>\n The consequences of poor sleep<\/strong><\/b> are well known. In addition to reduced performance and concentration, it can lead to cardiovascular disease and hypertension, obesity and diabetes, cancer and depression.<\/p>\n <\/p>\n That’s why, if there’s one subject that successful decision-makers don’t joke about<\/strong><\/b>, it’s sleep, whether it’s their daily routine or the quality of their mattress.<\/p>\n <\/p>\n <\/p>\n As busy as they are, billionaires understand the importance of sleep, sometimes to their detriment. The key is toavoid accumulating a sleep debt, which is detrimental to their physical and mental fitness.<\/strong><\/b><\/p>\n <\/p>\n <\/p>\n Although needs vary from one individual to another, the recommended amount of sleep for an adult (aged 26 to 64) is between seven and ten hours a night <\/strong><\/b>, and between 7 and 8 hours for people over 65.<\/p>\n <\/p>\n Most entrepreneurs adhere to a strict sleep routine<\/strong><\/b>, like Jeff Bezos<\/strong><\/b>, ex-chief executive of business giant Amazon. He proclaims loud and clear that he needs eight hours a night, and goes to bed at 9pm<\/strong><\/b>. He gets up early enough<\/strong><\/b> (5 a.m.) to scan the press and have breakfast with his children<\/strong><\/b>. Elon Musk<\/strong><\/b>, the mastermind behind Tesla, SpaceX and X, admits to having neglected his sleep for a long time. He has had to rethink his habits, now<\/strong><\/b> sleeping 6 hours a night, closing his eyes at 1am and reopening them at 7am<\/strong><\/b>.<\/p>\n <\/p>\nHow to optimize your sleep?<\/h2>\n
