We are forever being told that we should get 8 hours quality sleep a night but how many of us actually do?
A recent study involving a smartphone app and the data that it produced has revealed the sleeping patterns of people around the World.
The study published on Science Advances found that most of us aren’t getting anywhere near enough sleep and that a lack of sleep is mainly determined by the time people go to bed.
The average amount of time spent asleep varies from between seven hours and 24 minutes in Singapore and Japan to eight hours and 12 minutes in Holland.
Even cutting short your sleep by just 30 minutes can have a major impact on the cognitive abilities of the brain, the study found.
Some of the most significant findings involved women aged between 30-60 on average slept for 30 minutes longer than men of the same age.
Middle aged men sleep the least with many failing to get anywhere near the recommended 8 hours.
The study also found that people who spend significant amounts of time in daylight on a daily basis tended to sleep earlier as well as getting more sleep than those who spent more time in artificial light, the team from the University of Michigan found.
This pioneering study of worldwide sleep patterns combined mathematical modelling, mobile apps as well as regularly available data to find the roles society and biology play in sleeping patterns around the world.
The team used the Entrain smartphone app that is said to reduce the affects of jetlag to gather data of thousands of respondents from 100 different nations.
Another recent study carried out by the Centers of Disease Control and Prevention found that a chronic lack of sleep can increase the risk of heart disease, obesity and hypertension.
