How Eating Sugar Before Bed Affects Your Sleep

Do you have a sweet tooth and frequently have an additional plate of dessert after dinner? Furthermore, do you ever have difficulties sleeping after eating sweets, even if you’ve been sleeping on the best mattress for more than an hour? Well, if yes, then you are not the only one.

Sugar is an essential part of life. It is a crucial ingredient in cakes, cookies, pastries, and other sweets that we consume every day. However, it also has its adverse effects on your health and mood. It has been shown that sugar before bed can lead to sleep problems. It also leads to increased weight and drowsiness in the morning.

In this post, we’ll look at how a high-sugar diet before hitting the mattress can impact your sleep in the long run.

What Does Sugar Do to Your Body When You Eat It?


Sugar is often considered an innocent food because it’s not thought of as harmful, and it doesn’t have any added ingredients that can cause harm to your body. Sugars in meals are metabolized into glucose and fructose, which the body may absorb. Sugar enters the blood system and is swiftly transformed into glucose, which is then utilized for energy production. It can lead to an increased risk of diabetes and other health issues related to high blood sugar levels.

Furthermore, sugar is a carbohydrate that can be present naturally in the food or added while cooking or processing. It has been related to a variety of health issues, including cardiovascular disease and obesity.

However, it also has another significant consequence, and that is it impedes your sleep in such a manner that your lack of sleep leaves you yearning for more sweets.

How Does Eating Sugar Before Bed Affect the Quality of Your Sleep?


According to studies, those who consume a high-sugar diet sleep less soundly and are more agitated at night.


Sleep Deprivation

The sugar that you consume during the day is stored in your liver and muscles. It means that when you wake up, your body will be full of sugar, and it will take a long time for the liver to break down this stored sugar so that your blood can circulate properly again. Therefore, many people who are sleep-deprived end up having a hard time getting back to sleep after eating a lot of sugar.


Too much sugar late at night might be harmful to our health. When you consume sugar, your blood sugar concentrations increase and your pancreas produces insulin, which aids in the transportation of sugar straight into the cells, providing fuel to enable them to function. Consuming sugar, especially at night, causes overstimulation. It provides you with energy and prepares you for actions, but that’s not what is good for us at night. We are wired to turn off towards the end of each day.

Impaired slow-wave sleep

Low fiber intake, as well as excessive saturated fat and sugar consumption, is related to lighter, less restorative sleep and more wakefulness. In different terms, persons who consume more sugar spend significantly fewer hours in profound, slow-wave sleep, which is critical for the relaxation and recovery of the body, mind, and psyche.

Slow-wave sleep has always been crucial for adequate sleep. Slow-wave sleep is also essential for maintaining regular metabolic activity and a healthy immune system, which are often damaged when excessive amounts of sugar is eaten. To be honest, sugar is not a friend of a good night’s sleep.

Causes insomnia

Poor sleep has been connected to an upsurge in our appetite hormone ghrelin and our anxiety hormone cortisol, both of which are linked to a rise in our craving for sugary snacks. Basically, we all know that when we feel exhausted, we’re more inclined to seek for beverages or foods that will offer us an immediate boost of energy rather than hitting the mattress for a good night’s sleep. And the majority of these options are heavy in sugar. But sugar leads to sleeplessness.

So, if lack of sleep causes more sugar consumption, then higher sugar consumption leads to insomnia, which could turn into an unfortunate loop.

What Foods Contain Sugars?

Sugars are a natural part of our diet, but some foods can have more than the recommended daily limit. There are many ways to avoid overdoing it with sugars before bedtime and make sure that your body is receiving the nourishment it requires.

The most common sugars found in food items are fructose and glucose. Fruits, honey, and high-fructose syrup all contain fructose. Glucose is found in foods like slices of bread, potatoes, and fruit juices. It’s critical to keep track of the amount of sugar you eat so you don’t overdo it before hitting the mattress.

Some people believe that white sugar is better for their health than other types of sweeteners because they contain fewer calories. Other research, however, indicates that white sugar has the same detrimental repercussions on health as high-fructose corn syrup or artificial sweeteners like saccharin or aspartame .

Sugars are natural and healthy for our bodies, but it is vital that we consume the right amount of them. You should not overdo it before bedtime because a study found that eating too many sweets can lead to insomnia.
