Ah, sleep. One of life’s most elusive mysteries. It always seems like we need more of it than we have available. Those who constantly wage this war might be interested in knowing which day of the week is best for sleep. A new study from the data analytics company Firstbeat has found what they believe to be the answer to that very question, and it’s not on the weekend as many may assume.

According to the Kentucky new outlet WLKY, the study found that Tuesday is actually the best night of the week for sleep. Monday is, obviously, no good as it’s the first day back to work for most people, so the body is still adjusting back to the regular routine. By Tuesday, however, most people are more relaxed and ready for a good night’s sleep.

“On the weekends you try to relax. You go out, you have a few drinks, you sleep a little longer but not as well,” said Dr. David Winslow with Chest Medicine Associates and Sleep Medicine Specialists. 

Winslow also believes people have overwhelmingly “trained” their bodies to not get optimum sleep, especially with things like cell phones. “You say the bed is for worrying, or for thinking about things, or the bed is for watching TV,” he said. “The bed should be for sleep.”

According to research from Harvard Medical School, the majority of adults require 7.5 to 8.5 hours of sleep every 24 hours. Unfortunately, most people are lucky to get that a couple of times each week.

For this most recent study, 5,000 men and women and their heart rate data was studied making it one of the largest studies of its kind. They studied the test subject’s sleep patterns for three consecutive days over the past decade.

“Your brain works better, your body works better, your mood is better, if you get enough sleep,” Winslow continued. “When the patient wakes up, instead of lying there, they can go to another room, sit and then go back. They have to be disciplined but if they continue that process, eventually they will learn that they are supposed to sleep.”
