New Research Claims that Night Owls are more Efficient than Early Risers


The effects of sleep deprivation are well established. It negatively affects our brain attention system. We generally tend to feel uneasy and less productive in the day after a disturbed night sleep. Doctors also recommend us to have sound sleep for 8 hours for good health. They also recommend to go to bed early and wake up in the early morning. 

New Research Claims that Night Owls are more Efficient than Early Risers


However, some of us are accustomed to work at night than in early hours of the morning. There are also no reports on the productivity of early risers and night owls (who work late in the night). A new Research undertaken by the scientists from the higher school of Economics and Oxford university provides insights about the night activities of two types of individuals .




Nicola Barclay and Andriy Myachykov carried out a study to know the effect of sleep deprivation on people with different chronotypes. (body clock of an individual). They studied how the increase in night spent awake effects the attention system of early risers and night owls.

Twenty-six (26) volunteers (13 male and 13 female ) with an average age of 25 participated in the study.They were instructed to stay awake for 18 hours from 8 am to 2 am and carry their normal routine.They were subjected to undergo Attention Network Test (ANT) and morning and eveningness questionnaire at the beginning and the end of awake time.

The researchers did not find any difference in the the  results of ANT test conducted in the morning. However, there was sharp contrast seen in ANT test done in the evening. Early risers completed the test in quicker time than the night owls. But the productivity was far higher in night owls compared to early risers. Early risers committed more mistakes than the night owls.



Andriy Myachykov attributed that the night owls took the task seriously and garnered more time and attention during their favorite hours ie late evening or night. So that’s why even though they took more time to complete the task the accuracy is much higher than the early risers.



The second ANT done in the early hours also yielded the same results where in night owls are slower than early risers but more efficient. Andy Myachykov explained that the night owls working at late hours sacrifice speed for accuracy. Further research has to be carried in the direction to know how this speed and accuracy influences attention-related tasks. The study was published in the journal Experimental Brain Research.
