Poor sleep can lead to worrying and worrying can lead to poor sleep, according to the mental-health charity Mind.
A lack of shut eye is considered a problem when it impacts on a person’s daily life.
As a result, they may feel anxious if they believe lack of sleep prevents them from rationalising their thoughts.
Insomnia is also associated with depression, psychosis and PTSD.
Establishing a sleep routine where you go to bed and get up at the same time every day can help a person spend less time in bed and more time asleep.
Calming music, breathing exercises, visualising pleasant memories and meditation also encourage shut eye.
Having tech-free time an hour or so before bed can also prepare you for sleep.
If you still struggle to nod off, keeping a sleep diary where you record the hours you spend asleep and the quality of your shut eye on a scale of one to five can be a good thing to show your doctor.
Also note how many times you wake in the night, if you need to nap, if you have nightmares, your diet and your general mood.
Sleep problems can be a sign of an underlying physical condition, like pain.
Talking therapies can help your recongise unhelpful thought patterns that might affect sleep.
While medication, such as sleeping pills, can help break short periods of insomnia and help you return to better a sleeping pattern.
