A study found that ‘evening people’ who are active in the evening have 14% higher cognitive function than ‘morning people’ who are active mainly in the morning.

The Korea Institute of Oriental Medicine announced on the 23rd that the research team led by Dr. Ji-eun Park of the Oriental Medicine Data Department, together with the research team at Imperial College London in the UK, discovered the relationship between sleep patterns such as morning and evening types and cognitive functions, and produced these results. The research results were published in the latest issues of the international mental health journal ‘Journal of Emotional Disorders’ and the British ‘Journal of Public Health Medicine’.

The research team analyzed the cognitive function differences between ‘morning people’ who go to bed early and wake up early and are active, and ‘evening people’ who go to bed late and wake up late. Until now, research on the effects of sleep on human cognitive function has focused on sleep time and sleep quality, and there have not been many studies that analyzed activity time zones according to individual preference.

The research team collaborated with Imperial College London in the UK to utilize large-scale data from Korea and the UK. They analyzed data from approximately 26,800,000 people aged 53 to 86 from a biobank database collected from 500,000 UK adults using cross-sectional analysis techniques.

Cross-sectional analysis is an analytical method that measures group characteristics, including variables such as age groups, gender, and race, at a specific point in time.

As a result, it was found that cognitive functions of evening type people, who are mainly active in the late evening hours, were higher. After the research team classified morning and evening types according to their waking and sleeping times and tested their cognitive functions, they confirmed statistics that the cognitive functions of evening types were 7-14% higher than those of morning types.

The research team also confirmed that the amount of sleep that can reduce the risk of memory decline varies depending on whether the preferred time zone is morning or evening. For morning people, the appropriate amount of sleep is 5 to 6 hours, while for evening people, the appropriate amount of sleep that can prevent memory decline is 7 to 8 hours.

Dr. Park said, “Each person’s chronotype, whether they are a morning person or an evening person, is an important factor that affects the quality of their sleep and their health,” and added, “We will continue to conduct research on this in the future to contribute to improving national health.”
