If you've ever had a good night's kip disturbed by cheese, or that last coffee, you'll be aware of these items' ability to wreak havoc on getting some shut-eye.
The difference between having a good night's sleep and falling short of that can be huge. The knock-on effects of sleep deprivation can lead to weight-gain, high blood pressure - and even heart disease.
To this end, sleep has become big business opportunity. There are pills, apps, teas, sprays and books which all promise to help send us off into a deep and replenishing slumber. But if you've tried every lotion, potion, tablet and piece of tech out there and found nothing really works, then there are a few dietary tweaks which might help.
It's not always possible to control what you eat - especially when socialising in the evening. But if possible, both nutritionists and sleep experts have put their heads together and revealed in Health what to avoid eating before bed.
1. Bacon cheeseburger
It's probably no surprise how wolfing one of these down - however delicious - negatively impacts sleep. After all, it's never been exactly championed as a health food. The fat contained in a bacon cheeseburger stimulates acid production in the stomach. This, in turn, can spill in to the oesophagus, leading to heartburn, which is guaranteed to keep you awake.
Foods high in fat such as a cheeseburger also loosen the barrier between the stomach and the oesophagus, which means that same acid can leak into places where it shouldn't be.
Forget the term 'nightcap', according to the site, having a couple of drinks to unwind before bed time is bad news for having a decent sleep. This is because alcohol metabolises rapidly in our systems - which is why you may find you wake up several times during the night after a few drinks. Not only this, but it also damages the 'quality' of sleep you're getting
Alcohol also amplifies and strengthens any snoring. So if you share a bed, that's something to consider too.
3. Dark chocolate
Bad news for chocoholics or those with a sweet tooth. While dark chocolate is often touted as a healthier alternative to other chocolatey treats, it's not a perfect substitute.
