"But what this can do is create a link in your subconscious between your bed and being awake consuming content, rather than sleeping.
"This can make it increasingly difficult for your mind to relax and allow you to fall asleep when you get into bed to go to sleep, resulting in a disrupted night's sleep."
In fact, the sleep medicine specialist from GenesisCare Australia said our "sleep environment" plays an important part in getting those all important hours of rest.
"It is very important that you avoid using your bed for anything other than sleep or sex, and instead stick to the lounge if you want to stay up late bingeing your new favourite show," Dr Justin said.
"Sometimes a person can feel exhausted, but will lay in bed unable to sleep. This can be due to a sub-optimal sleep environment that prevents their body from being able to fall asleep or achieve a deep sleep, which allows the body to rest."
But not getting sleep can have detrimental consequences on your body, Dr Justin explains.
"Many sleep disorders are also strongly connected to cardiovascular disease (CVD), with poor sleep quality potentially causing or contributing to CVD, and CVD also potentially disturbing sleep.
He added that a poor night's sleep is also associated with stress, illness and poor health.
While changes to your routine such as shift work or long working hours, travel and jet lag are all common factors that can lead to disrupted sleep, Dr Justin believes the major problem is a person's sleep environment.
Luckily, Dr Justin said there are several simple things that you can do to help create an ideal sleep environment, which may lead to a better night's sleep. Hooray.
