Why Sugar is Keeping You Up at Night

Sugar is no friend to a good night’s sleep – in fact, a diet high in this addictive stuff could be contributing to unstable sleep cycles, fatigue, mood swings and even increased sugar cravings! Here’s what you need to know.

Ah, sugar. Sweet and oh-so-addictive. But there’s nothing sweet about what it’s doing to your sleep cycles. We all know that consuming too much of the stuff can wreak havoc on our waistlines, but did you know that it can have a similar effect on our sleep? Let's start with the basics.

What happens to your body when you eat too much sugar

When we eat fructose, especially in ultra-processed foods void of fibre, we end up with a spike in our blood-sugar levels, which in turn triggers the release of insulin to bring those levels back down. While this might not seem like a big deal, it can actually have a significant impact on our sleep. When our blood-sugar levels drop rapidly, our bodies release stress hormones like cortisol and adrenaline to compensate. This can make it harder to fall asleep and stay asleep throughout the night. In addition, sugar can disrupt the production of melatonin, a hormone that helps regulate our sleep-wake cycle. Without enough melatonin, we may struggle to feel drowsy when it's time for bed. But it doesn’t stop there! Sugar can also cause inflammation in the body, which can also cause unstable hormone productions, with far-reaching effects into our sleeping, eating and waking cycles. Sugar can also disrupt the quality of our Rapid Eye Movement (REM) sleep, and this stage of the sleep cycle is essential for cognitive function, learning, and memory consolidation. It’s also important that we complete the REM cycle in order to have a quality sleep, and the research shows that excess sugar consumption may well throw a spanner in the works here, finding that those who ate more sugary, processed foods had disrupted sleep, and therefore a disrupted day. So, the verdict is in – sugar is a sleep nightmare! Pun intended.

What to do

Along with cutting out excess sugar, you’ll also want to keep an eye on your screen usage – screens and lighting are overdosing us with hours of exposure to blue light each day. Research has found a direct link between this overexposure and poor sleep. But, what can you do to break the cycle of sugar-induced sleeplessness? First and foremost, try to cut back on your added sugar intake or even cut it out entirely. Opt for whole foods instead of processed snacks and drinks, and try to limit your intake of sugary treats to special occasions. You can also try incorporating sleep-promoting foods into your diet, such as cherries, almonds and walnuts – the omega 3s in the latter are highly beneficial for hormone regulation, while the healthy fats leave us feeling satisfied. You’ll also want to make sure you're getting enough exercise during the day to help regulate your sleep-wake cycle. A tired body is more likely to fall asleep quickly and stay asleep throughout the night.
