Power naps help you get better decision making

Lack of sleep can lead to many health problems both physiologically and psychologically. But if you are lucky enough to get some power throughout the day, you still have a fair chance to avoid the harmful effects of less sleep. Feeling sleepy or coarse in the morning, especially if you have not slept well during the night will affect you in a number of ways – it can hamper productivity, perception and determination. According to a study published in the Journal of Sleep Research, a welfare dope could prevent decision-making to be saddened by subconscious influences. Just a simple nap can help improve the symptoms of being tired.

Headed by Liz Coulthard, Ph.D., a university lecturer studying cognitive neuroscience and research assistant Netasha Shaikh, Ph.D., both at the University of Bristol's medical school in the United Kingdom, this study investigated the effects of a 90-minute nap ( quite long) on ​​people's ability to sort through the subconscious factors that influence their decision.

In the study 1

6 Volunteers took a 90-minute nap – enough to compare with a full sleep cycle – before performing a series of tricky association tests designed to test brain decision making in deliberately confusing circumstances. In real life, subconscious factors like hunger can lead to impulsive decision making. In this test, the researchers used words to subconsciously complicate the decision-making process.

This attempt was designed to make it difficult for participants to make the right decision so that the team could observe how sleep affected that process. Participants were told to simply identify a word that flashed on the screen as a negative or positive word. Obviously it was not as simple as that. Just before they saw the main word another positive or negative word blinked for 33 milliseconds – so briefly that it was not possible to consciously record what this word was but long enough for it subconsciously to retrieve it. It was the "unconscious mind".

As you may expect, previous studies have shown that it is an unconscious primary that is congruent with the main word (for example, "peace" followed by "happy" two positive words) to categorize the main word. But in non-congruent words it is much more difficult to identify the second word, no matter how sleepy you can be.

However, the 16 volunteers who performed the test immediately after a 90-minute nap added words in the right categories faster – indicating that the task was easier than it had been before they went back to their beds in the lab. The average time for participants to identify the words incongruent pairs fell from over 670 milliseconds before they lasted for more than 610 milliseconds after napping. There is a slight difference, but scientists think it might be a criticism of what's going on under the surface.
