What’s this about sleep being linked with success in athletics? I’ve read that sleep is independently linked with longevity, but athletic endeavors?
Bottom line: sufficient sleep for brain is way more important than many would believe. And, yes, studies are beginning to link adequate amounts of sleep with how successful an individual is athletically. Short sleep duration of less than seven hours per night is associated with a greater likelihood of developing obesity, high blood pressure, diabetes, coronary heart disease, stroke, frequent mental distress, reduced athletic performance, and even a shortened life. There are some interesting pieces to this puzzle. For example, athletic performance appears to be best in the evening when one’s core body temperature is highest. On the other hand, training exercises done late at night interferes with the brain’s circadian rhythm. This can make it more difficult to fall asleep and, depending on when you get up in the morning, can actually result in insufficient sleep.
