In the past studies had proved that
people who slept for a night perform better on a visual texture-differentiating
test than people who do immediately after learning it. Mednick et al studies
revealed that people who took 60 to 90 minutes of nap perform equally well with
people who slept full night. (Mednick
and colleagues, Nature Neuroscience, 2003). A daytime nap can bring advantages to a various memory domain.
In one latest study shows the ability to bring back memories in volunteers who
learned single words as well as random word combinations. 50% of the volunteer
nap for 1.5 hours while the other 50% of them stayed awake. Both groups are
then tested, and the result showed that volunteers who napped recalled more
word combinations substantially. This type of “associative memory” is dependent
on hippocampus function which can be enhanced by naps. (Mecklinger ,Neurobiology of Learning and Memory 2015).

According to Mednick, a short nap
works like a dose of caffeine in enhancing learning capabilities. She realized
individuals who took a nap shows better performance on a verbal-word recall
task rather than those who consumed caffeine. (Behavioural Brain Research, 2008).

Performance, emotion and reaction time
increases with the length of napping time. An 8-hour nap is best in sustaining
the three aspects as compared to consuming caffeine.  Overall, daytime nap helps in maintaining

According to Gauri Sarda-Joshi, a social psychologist,

comparison to those who does not have afternoon nap. They are more energized
and feel less distress after the naps. A study done by University of Michigan
showed that people who took an hour nap are less impetuous and more tolerate to
frustration compared to those who watch nature documentary for an hour. (Personality and Individual Differences,
