It is clear that those who get up early have a low risk of depression and a high degree of well-being
adjusted by the clock gene , it is quite difficult to adjust the rhythm of sleep by one's own will, but according to a study by Jessica Olorin of the University of Exeter and others, It turns out that 'morning people have a lower risk of depression and are happier.'
There are two types of human beings, the 'morning type' who is good at getting up early and the 'night type' who tends to stay up late. Since the rhythm of the body clock unique to humans is

From various studies conducted in the past, it is known that various gene mutants contained in clock genes affect chronotypes such as morning type and night type. Therefore, O'Loughlin et al. Investigated the genetic data of about 450,000 people, including the data of about 230,000 people who answered the questionnaire, and investigated the relationship between depression, bedtime, and genes.
The questionnaire asked 'whether I am morning or night', 'have I experienced depressive symptoms', and 'how meaningful do I feel in my life?' As a result of the analysis by O'Loughlin et al., 62.6% of the investigated genetic data was classified as morning type, and this result was similar to the classification result of chronotype obtained by the questionnaire.
In addition, it was found that those who are genetically classified as morning type and those who answered 'prefer early rising' have a lower risk of developing depression and higher happiness than those who answered 'early rising'. In addition, it was also found that when the rhythm of sleep is greatly deviated due to work etc., it is strongly associated with anxiety, depression, and deterioration of happiness.
'We found that people with morning depression were more depressed and in better health. If further research establishes a relationship between depression and genetic, circadian rhythm disturbances, O'Loughlin said. In the future, flexibility on working days could be introduced to improve the mental health of people who work night shifts. '
