I believe that a good night’s sleep is key for a good day of trading but how much sleep?
Generations have believed that a full 8 hours was optimal but now researchers are saying that 7 hours might be better.
Other recent research has shown that skimping on a full night’s sleep, even by 20 minutes, impairs performance and memory the next day. And getting too much sleep—not just too little of it—is associated with health problems including diabetes, obesity and cardiovascular disease and with higher rates of death, studies show.
“The lowest mortality and morbidity is with seven hours,” said Shawn Youngstedt, a professor in the College of Nursing and Health Innovation at Arizona State University Phoenix. “Eight hours or more has consistently been shown to be hazardous,” says Dr. Youngstedt, who researches the effects of oversleeping.
