When it comes to winding down for the night, we all know there are certain foods and drinks that we shouldn't consume as they can have an impact on the quality of our sleep.
Alcohol is obviously a major contributor to disruptive sleep but it's not the only beverage you should avoid drinking before bed.
Caffeine is a big one to avoid, and many people may stop drinking tea or coffee in the early afternoon to avoid being unable to drift off later in the day.
But you might not have thought about caffeine being in other products - such as your favourite fizzy drinks which you might have a glass or can of with dinner, or after dinner.
This is something Chris Tattersall, the Managing Director of Woolroom, who has been dubbed the 'master of sleep', has urged people to think about.
Speaking to The Mirror, the expert shared some of the biggest things that are needed for a good night's sleep and some of the things that disrupt it.
He started by saying that he advises people not to eat for three hours before going to sleep.
"Try to eat as early as possible and think about what you eat as well," he said, before going on to warn about caffeine.
"Think about things like caffeine, if you're particularly prone to caffeine affecting you then don't have it too late in the day.
"Many people say don't have it after midday.
"But in terms of caffeine-based drinks, you also have to think about fizzy drinks as well as they might contain caffeine.
"Why not consider drinking water instead?
"We naturally perspire and lose half a litre to a litre of moisture at night, so be sure to replenish during the day to make sure your body is hydrated enough. This will enable you to sleep better and prevent you from waking up feeling a bit dry in the mouth."
Chris went on to encourage people to also think about their sleeping environment, explaining that the ideal temperature to sleep in a bedroom is between 16 and 18 degrees celsius.
Obviously getting your room to this temperature can be quite challenging in summer, so he urges people to think hard about ventilation to keep the air fresh and lower the heat.
And if you're concerned about being too hot at night, he previously explained to the publication how your bedding and mattress type could be having an impact.
Chris, who joined Woolroom in 2012, explained: "Somebody who has a memory foam mattress is going to sleep very hot as memory foam is hugely dense and it throws all the heat back at you.
"You'd need to be thinking about the duvet type that they use on top of that because it's going to create a lot more heat.
"So if you've changed mattress to a memory foam, what you had before with your duvet weight is not going to be appropriate because it's probably gonna be too heavy."
He went on to claim that most bedding with synthetic fibres like polyester face similar issues to memory foam and aren't great for "managing moisture".
They throw all of that heat and humidity back at you as well. So we have a challenge there in terms of our sleep environment," he added.
Instead, Chris claims the key to a better night's sleep, no matter the weather, is to give wool a try - be it in your mattress or bedding
The expert, who worked with the University of Leeds to test wool and find out how it impacts sleep, says the natural material provides "deeper, more regenerative sleep" due to the way it helps regulate temperature.
He added: "Actually, the old saying 'nature knows best' is true and what we need to do is return to how we used to sleep 50 to 70 years ago with more natural fibres, because we can sleep better and we can sleep deeper."
