Sleep is known to be an essential part of good health, and yet an increasing number of us don’t get enough good quality shuteye.

With this in mind, we round up four studies which emphasise how sleep could boost our health and well-being, and what might motivate us to get more of it.
Improve your gut health

As well as the recent focus on the importance of sleep for our health, there has also been a lot of research looking into how our gut can affect our well-being.

The findings from a study published last year in the journal Plos One showed that in fact, a bad night’s sleep has a negative effect on gut health, which in turn could lead to other health issues.

Although the study was a preliminary one and looked at just 26 male participants, the researchers found increased sleep efficiency – which is the percentage of time spent asleep in bed – and total sleep time were positively associated with a more diverse gut microbiome, which is also known to be a “better” gut microbiome.

The more diverse someone’s gut microbiome is, the likelier they are to have better overall health.

Boost mental health

Research has also shown that getting enough shuteye could have a positive effect on our mental health, including the mental health of children and teens.

A recent study published earlier this year found that after following 799 children from the age of six to 12, those who got the least sleep had the greatest risk of developing mental health issues.

Boys who slept the least hours had an increased risk of developing behavioural problems, and both boys and girls who slept the least had a higher risk of future emotional problems.

Another study, published last year, which looked at 110,496 college students also found that insufficient sleep was associated with a variety of mental health problems and symptoms including depression, feelings of hopelessness and anger, and anxiety.

Protect your heart

More and more studies are now looking at how sleep can affect our heart health.

One study that looked at 1,992 men and women aged 45 to 84 years old over a five-year period found that participants who got a different amount of sleep each night or who had no regular bedtime and wake-up times had more than double the risk of experiencing a cardiovascular event compared to those with the most regular sleep patterns.

A large-scale study published last year which looked at 461,347 individuals age 40 to 69 also found sleeping less than six hours per night was associated with a 20% higher risk of having a heart attack compared to those who slept six to nine hours per night, and sleeping more than nine hours each night was associated with a 34% higher risk.

Boost your performance

Sleep, or a lack of it, could be affecting the academic performance of kids in school, and our own performance at work according to recent research.

A large-scale study which looked at 49,050 children and teens age six to 17-years old found that children who get a sufficient amount of sleep on weeknights are 44% more likely to show interest and curiosity in learning new things, 33% more likely to do their homework, 28% more likely to care about doing well in school, and 14% more likely to finish tasks, compared with children who did not get sufficient sleep.

A US study which looked at the effect of 24 hours of sleep deprivation on 234 adult participants also found that a lack of sleep can decrease our ability to complete tasks, leading to mistakes at work that can range from basic errors to possibly even dangerous mistakes.
