Scientific Insights and a Healthy Sleep Guide for the General Public


Recently, a tip has been circulating online suggesting that consuming a small amount of sugar before bedtime can help prevent nighttime awakenings due to drops in blood sugar, thereby improving sleep quality. For those who often wake up at night feeling hungry, this advice may sound appealing. But is it really effective for healthy individuals? Let’s explore the scientific basis, expert insights, and practical dietary strategies for better sleep.




The Relationship Between Sleep, Blood Sugar, and Sugar Intake


While the body uses less energy during sleep, a prolonged fasting state can gradually lower blood sugar levels. If blood sugar drops too much, the brain may trigger an arousal response, interrupting sleep. However, for healthy individuals, the body’s natural homeostasis typically prevents blood sugar from falling to disruptive levels.


On the contrary, consuming excessive simple sugars before bed can cause a rapid spike in blood sugar followed by a sharp drop, prompting the release of arousal hormones like cortisol and adrenaline—ultimately disturbing sleep.




Does Eating Sugar at Night Really Help You Sleep?

The Downside of Simple Sugars


According to a study by Columbia University, women who frequently consumed refined carbohydrates and sugary foods were more likely to experience insomnia. Sudden increases in blood sugar levels lead to insulin surges, followed by rapid declines in glucose and subsequent overproduction of arousal hormones. This cycle may result in difficulty falling and staying asleep, especially after consuming sweet snacks before bed.


Healthier Ways to Use Sugar to Support Sleep

Not all sugars are harmful. Natural sugars such as a small amount of honey can help stabilize blood sugar levels and promote the production of GABA (gamma-aminobutyric acid), a neurotransmitter that calms the nervous system and promotes sleep. For instance, a teaspoon or two of honey mixed with warm water or milk may prevent nighttime awakenings caused by hunger.


In addition, nuts such as walnuts and almonds are rich in melatonin and magnesium, both of which help regulate the sleep cycle and calm the nervous system.




Sleep-Friendly Eating Habits: What and When to Eat

Foods to Avoid Before Bed:

  • Simple sugars like candy, chocolate, soda

  • Refined carbohydrates like white bread and snacks

  • Stimulants such as caffeine, chocolate, and energy drinks

These can cause rapid blood sugar fluctuations and interfere with sleep. Avoid these at least two hours before bedtime.


Foods That Can Help Promote Sleep:

  • Milk and cheese: Rich in tryptophan and calcium, they help produce serotonin and melatonin.

  • Bananas, kiwis, tomatoes: Contain natural sleep-inducing compounds.

  • Oatmeal, brown rice, whole grain cereal: Provide complex carbohydrates that raise blood sugar slowly and steadily.

  • Honey (in moderation): Helps stabilize blood sugar and calm the nervous system.

  • Walnuts, almonds: Contain melatonin and magnesium, which support healthy sleep cycles.


Optimal Meal Timing:

  • Finish dinner 3–4 hours before going to bed.

  • If you feel hungry before bed, have a small, healthy snack 1 hour prior—something like warm milk, a banana, a few nuts, or a teaspoon of honey.

  • Avoid overeating, late-night snacks, and excessive sugar.






Practical Sleep Tips for Healthy Individuals

  1. Avoid simple sugars 2 hours before sleep
    Foods high in sugar can cause blood sugar to spike and crash, which disturbs sleep.

  2. Use small amounts of honey, nuts, or milk for gentle support
    Honey stabilizes blood sugar; milk and nuts are rich in sleep-friendly compounds like melatonin and tryptophan.

  3. Choose complex-carb snacks
    Oatmeal, brown rice, or whole grain cereals can help maintain stable energy levels overnight.

  4. Avoid caffeine, alcohol, and heavy meals
    These overstimulate the body or burden the digestive system, impairing sleep quality.

  5. If hunger keeps you awake, opt for a small, healthy snack
    A banana, a small handful of almonds, warm milk, or honey water may help you fall and stay asleep.






Conclusion: How to Use Sugar Wisely Before Bed

For healthy individuals, consuming a small amount of sugar before bed is not a universally recommended strategy. In fact, simple sugars and refined carbohydrates can disrupt sleep. However, small amounts of honey, milk, nuts, or complex carbohydrates may be helpful in promoting restful sleep—especially when chosen and timed wisely.

The key lies in what, how much, and when you eat. A good night’s sleep depends not just on the right foods, but also on regular routines, mindful eating, and balanced lifestyle choices.
