- Scientists have discovered a link between circadian rhythm and income levels
- People who are more active in the evening tend to earn less than early risers
Maybe the early bird really does catch the worm as those who burn the midnight oil are likely to earn 4 per cent less than morning people, research suggests.
Scientists have discovered a link between circadian rhythm, the body’s internal clock, and income levels.
According to the findings, individuals who tend to be more active in the evening also tend to exhibit characteristics that are linked with earning less.
A team from the University of Oulu in Finland analysed data on 12,000 people, collecting information on their education, work experience, lifestyle choices and health.

They discovered night owls tended to exhibit more ‘bad’ characteristics such as drinking more alcohol, smoking, lack of exercise, high BMI, an unhealthy diet and longer screen time.
And this was linked to lower levels of income in middle age, they said.
Among men, the negative influence of being a night owl – also known as having an ‘evening chronotype’ – was linked to a 4 per cent lower average annual income.
This is the equivalent of a person earning £48,000 ($58,000) per year compared to £50,000 ($61,000).
Dr Andrew Conlin, who worked on the study, said: ‘Evening chronotypes tend to accumulate less human, social and health capital.

‘On average, accruing less work experience and making poorer choices regarding healthy lifestyle are associated with lower levels of income in middle age.’
The team said their findings emphasise the importance of recognising and accommodating individuals’ chronotypes in the workplace.
Since night owls are more active and alert in the evenings, they tend to have sleep problems and may not be working during their most productive period of the day, they added.
The study, published in the journal Economics and Human Biology, said: ‘Evening-type individuals could likely earn higher wages through better lifestyle choices.’
