Not everyone really puts that much thought into exactly how long they want to be asleep in bed for.

But, perhaps especially when you're working every day, you can find yourself setting a target for how many hours you want to be snoozing for!

Premier Inn reported last year that on average Brits want to sleep for seven hours a night. However, more than three quarters of its survey sample said they don't actually get this amount of shut-eye.

If you feel you need to do something about getting better kip, there is always help at hand.

"Everyone is different and has their own personal preferences, but there are some common factors that can affect all of us when it comes to sleep," expert Dr Dan Robotham explained in 2011.

The Mental Health Foundation senior research officer recommended eye masks as an option to try for people who are finding their room isn't dark enough for them.

Ear plugs, on the other hand, were recommended for people dealing with loud noise to try using.

"If you’re finding it difficult to get to sleep, try getting up for a while until you feel sleepier, rather than lying in bed and worrying about the fact you aren’t managing to sleep," he also suggested.

People should also avoid caffeine during the latter part of the day, as well as eating a lot late at night.

He said that though people's sleep could be improved though exercising – and that they could cut down on anxiety and relieve stressful feelings by doing this – they shouldn't exercise during the late evening.

"The adrenaline that your body produces when you exercise can make it more difficult to get to sleep," the expert explained.

People suffering from mental health issues like depression or anxiety might find their sleep is affected by these, he added.

"It is important to speak with your GP about a combined approach that tackles both the mental health issue and the sleep problem," he told people in this position.
