Tweaking sleeping habits can shift people’s body clocks and improve their wellbeing, say scientists in the UK and Australia.
They focused on “night owls”, whose bodies’ drive them to stay up late into the night.
Techniques used included consistent bedtimes, avoiding caffeine and getting plenty of morning sunshine.
The researchers say their approach may seem obvious, but could make an important difference to people’s lives.
Everyone has a body clock whose rhythms follow the rising and the setting of the sun. It is why we sleep at night.
But some people’s clocks run later than others.
Morning-led “larks” tend to wake early, but struggle to stay up in the evening; night owls are the opposite, preferring a lie-in and remaining active late into the night.
