Snoozing helps make important decisions

Snoozing helps make important decisions


A study carried out by researchers from the University of Bristol (United Kingdom), published in the 'Journal of Sleep Research', has shown that napping helps weigh the pros and cons before making an important decision.

In addition, the results have confirmed the benefits of the siesta in cognitive function and, even, that in this period information is processed that is not conscious.

To reach this conclusion, the researchers analyzed two groups of people of different ages, asking them to perform a task that concealed another and, the rest, to respond when they saw a red or blue square on a screen. The participants practiced the tasks and then stayed awake or took a 90-minute nap before going back to doing homework.

Using an EEG, which records the electrical activity produced naturally in the brain, the researchers measured the change in brain activity and the response before and after the nap. Thus, they verified that the suspension (but not the reactivation) improved the processing speed in the task in which there was another hidden, but not in the control task, which suggests specific improvements of the dream in the processing of prime numbers presented by subconscious form.

The findings suggest that even a short nap can help improve the answers and process the information. "More research is needed in a larger sample size to compare what happens between people of different ages," the experts said.
