Your cognitive abilities likely depend on whether you are a morning or an evening person
Sleeping patterns
Waking up early in the morning might not be all good for you. In fact, if you are sacrificing sleep to wake up early, then your mental abilities might take a hit.
A UK Biobank study, led by academics at Imperial College London, checked the sleep patterns and cognition of almost 27,000 participants to conclude that night owls perform better in cognitive tests.
The study also says that people who are more active in the evening are likely to be mentally sharper.
The study found "superior cognitive function" among the night owls and people who don't fit in any of the chronotypes - "morningness" or "eveningness".
Surprisingly, cognitive performance was likely to be worse in women when taken into consideration along with all other criteria,as per the study published inthe journal BMJ Public Health. Increasing age, an angina diagnosis, high blood pressure and diabetes also lowered the performance.
The study tried to understand the link between the duration of sleep, its quality and the chronotypes. The results clearly showed that people who got between seven and nine hours of sleep each night delivered excellently on tests that gauged intelligence, reasoning skills, reaction times and memory.

"Our study found that adults who are naturally more active in the evening - what we called 'eveningness' - tended to perform better on cognitive tests than those who are 'morning people'," lead author of the study, Dr Raha West, from the Department of Surgery and Cancer at Imperial College London, said.
She added that it is important to get enough sleep irrespective of what you prefer. Sleeping too little and sleeping too much, both are likely to have an adverse impact on cognitive abilities.
"This is crucial for keeping your brain healthy and functioning at its best," she said.
The researchers advised people to proactively manage their sleep patterns as "sleep duration has a direct effect on brain function" and to safeguard "the way our brains work".
