“For do but consider what an excellent thing sleep is: it is so inestimable a jewel, that, if a tyrant would give his crown for an hour’s slumber, it cannot be bought … sleep is that golden chain that ties health and our bodies together. Who complains of want, of wounds, of cares, of great men’s oppressions, of captivity, whilst he sleepeth? Beggars in their beds take as much pleasure as kings. Can we therefore surfeit on this delicate ambrosia? Can we drink too much of that, whereof to taste too little tumbles us into a churchyard; and to use it but indifferently throws us into Bedlam? No, no. Look upon Endymion, the Moon’s minion, who slept threescore and fifteen years, and was not a hair the worse for it. Can lying abed till noon then, being not the threescore and fifteen thousandth part of his nap, be hurtful? ”
The modern prevalence of jet travel and shift work has prompted considerable research in sleep and sleep-related issues, since many travellers and shift-workers struggle to find effective strategies for managing sleep. Thomas Dekker is certainly correct about the effects which sleep deprivation can have.
However, although Selene (the Moon) caused Endymion to sleep, she is unlikely to be of any help here. In fact, the full moon reduces hours slept, and this effect may underlie traditional beliefs in lunacy caused by the moon. Not to mention the legends about werewolves.
