Sleep has long been the secret weapon of athletes just as it should be for traders.
Scientists have a firm grasp on the purpose of certain automatic physical functions, like blinking, breathing, or digestion. When it comes to sleep, however, researchers still aren’t clear on why exactly your body needs to shut off every night. Details aside, one thing’s for sure: When you don’t sleep, your body revolts.
The effects of acute sleep deprivation—which is more akin to pulling an all-nighter than to getting just a few hours of sleep every night for weeks at a time (that’s chronic sleep deprivation)—generally kick in after 16 to 18 hours of being awake and get progressively worse with each proceeding hour. Your mind, heart, endocrine system, and immune system are all affected, malfunctioning in ways both subtle and severe.
The consequences of chronic sleep deprivation are far worse than one sleepless night. But the decision to pull an all-nighter just once can leave some serious damage in its wake.
