A lack of sleep could lead to heart disease, weight gain - and even change the way our DNA behaves, according to experts.

Professor of Sleep Medicine, Paul Gringras, has pulled back the covers to reveal what happens to our bodies after a poor night's sleep, with higher blood pressure and cholesterol also among the potential consequences of not getting enough rest.

“But, our DNA, and how our body knows what to do with it, is in fact susceptible to changes from outside factors - what we eat, whether we smoke, how stressed we are, and how we sleep.

“Although poor sleep doesn't change our actual DNA code, it does affect the epigenetic signals that control how our genes function, and it’s this that can have a negative effect on our day to day lives.

“Just one night’s bad sleep changes epigenetic signals to our DNA that cause weight gain and loss of muscle mass, and can affect the way that memories are laid down in the hippocampus - part of our brains.”

According to Professor Gringras, feeling tired can also make people more impulsive or likely to take risks as their judgement is impaired.

But it's not just health problems which can be affected by sleep, with accuracy, reaction time and split-second decision-making improved after a good night's rest.

Gringras added: “A rested basketball player will shoot more baskets, a swimmer will jump faster on the gun, and a rugby player will be more likely to make successful split-second decisions on the pitch.

“Exercise during the day can be helpful for sleep quantity and quality - the survey showed that 85 percent of people found their sleep improved when they exercised during the day.

“You can train really hard, put all the hours into strategy and match-day evaluation that you want, but the simple fact is that if you are not getting enough sleep, it will have a direct negative effect on your performance, which is why athletes and their teams put so much emphasis on good quality sleep regimes.”

To demonstrate the link between sleep and everyday performance, international rugby player Maro Itoje has teamed up with Simba to encourage the nation to #TryFor8 hours in bed every night via its new Simba Sleep App.

Maro and his support team believe that proper sleep should be disciplined, and is equally important as training or nutrition.

As part of the campaign, the rugby superstar will take a workout-like approach to coach the nation via Simba’s newly developed Simba Sleep App to train themselves into better sleep habits.

The app has weekly challenges to help sleepers take small steps to build better, lasting sleep habits.
