'Early to bed and early to rise makes and man healthy, wealthy and wise' Earely to bed and earely to rise, makes a man healthy, wealthy, and wise. John Clarke's Paroemiologia Anglo-Latina in 1639 (And I bet you thought it was from Benjamin Franklin, Poor Richard's Almanack, 1735 edition) In 1998 a study in the UK set out to test the veracity of this proverb (Gale C, Martyn C. Larks and owls and health, wealth, and wisdom. BMJ. 1998 Dec 19;317(7174):1675-7) The study investigates self-reported income, access to a car, standard of accommodation, performance on a test of cognitive function, state of health. It found that there was no indication that people defined as larks (to bed before 11 pm and up before 8 am) were more affluent than those with other sleeping patterns. On the contrary, owls had the largest mean income and were more likely to have access to a car. (There was also no evidence that larks were superior to those with other sleeping patterns concerning their cognitive performance or their state of health). Thus, the study provided no support for the idea that early rising had any benefit for socioeconomic, cognitive, or health status. Sleep and wages A study in 2014 found s that sleeping one extra hour per night on average increases wages by 16%, highlighting the importance of good sleep to human productivity. This increase in wages is greater than what an additional year of schooling would provide. [Gibson M, Shrader J. Time use and productivity: The wage returns to sleep 2014] Further research published in 2018 found even sleeping for 1 hour more a week was associated with a 1.1% increase in earnings. In the long term, this increased to up to 5%. (Gibson M, Shrader J. Time use and labor productivity: The returns to sleep. Review of Economics and Statistics. 2018 Dec 1;100(5):783-98) Sleep and wealth Sleep is the wealth of the poor as it is of the rich man, and the "tired sea- boy on the mast" sleeps better than many a "head that wears a crown." The tranquil sleep which the poor enjoy, many of the rich and powerful would give thousands to purchase. The renowned French financier once said, "Alas! why is there no sleep to be sold ? " Sleep was not in the market, at any quotations. Wealth will not buy health, or prolong life, or bring back youth. Anecdotes, Illustrative of Religious and Moral Truth By Matthew Denton 1873 An extensive interview study in the US found that those at or below the poverty line were less likely you are to regularly get more than sleep hours a night here the effect of poverty on sleep is multi-factorial, poorer housing conditions, unhealthy diet, unemployment etc., all play a part in the causing poor sleep. One consequence of poor sleep is that it can lead to an increase in risky behaviours. This may mean that you are more likely to gamble or play the market and taking those risks can seriously affect your finances. People who play online poker when sleep-deprived lose more money than when they are well-rested (Hamel A, Bastien C, Jacques C, Moreau A, Giroux I. Sleep or play online poker?: gambling behaviors and tilt symptoms while sleep deprived. Frontiers in Psychiatry. 2021 Jan 11;11:1540) not only that, but gambling behaviour can negatively affect sleep (Parhami I, Siani A, Rosenthal RJ, Fong TW. Pathological gambling, problem gambling and sleep complaints: An analysis of the National Comorbidity Survey: Replication (NCS-R). Journal of Gambling Studies. 2013 Jun 1;29(2):241-53) Good sleep is worth its weight in gold.
