Taking a spoonful of honey before bed is a popular folk remedy touted for promoting better sleep, soothing nighttime coughs, and stabilizing energy overnight. While it is not a magic cure for chronic insomnia, there is actual physiological science behind how raw or natural honey interacts with the body during sleep.
Here is how a bedtime spoonful affects your system:
1. The Liver and Glycogen Storage (“The Hibernation Diet” Theory)
Your brain continues to consume energy (primarily glucose) while you sleep. If your liver glycogen stores are low during the night, your brain panics slightly, prompting the adrenal glands to release stress hormones like cortisol and adrenaline to trigger a release of stored sugar.
-
How honey helps: Honey is a mix of natural fructose and glucose. The fructose is processed slowly by the liver to restock hepatic glycogen, while the glucose provides a steady trickle of fuel.
-
The result: Keeping your liver well-supplied prevents nighttime adrenaline spikes, helping you stay asleep rather than waking up abruptly in the middle of the night.
2. Gentle Insulin Response and Tryptophan Uptake
Consuming a small amount of carbohydrate (like honey) causes a minor, manageable release of insulin.
-
How it works: Insulin clears competing amino acids out of your bloodstream, allowing tryptophan—an amino acid found in your daily diet—to cross the blood-brain barrier more easily.
-
The result: Once inside the brain, tryptophan is converted into serotonin (the calming neurotransmitter) and subsequently into melatonin (the sleep-wake hormone).
3. Natural Cough and Throat Soothing
Honey has long been recognized as an effective demulcent—a substance that forms a soothing film over mucous membranes.
-
How it works: A spoonful coats an irritated throat, reducing the tickle that triggers nighttime coughing fits. Studies have even shown that honey can rival or outperform certain over-the-counter cough suppressants for upper respiratory irritation.
Important Considerations Before Trying It
-
Caloric and Sugar Content: Honey is a concentrated source of simple sugars and calories. If you are managing diabetes, insulin resistance, or watching your weight, factor that spoonful into your daily dietary intake.
-
Dental Hygiene: Eating sticky sugars right before bed without brushing your teeth afterward can significantly increase the risk of tooth decay and plaque buildup.
-
Reflux Caution: While some people find honey soothing, for individuals with severe acid reflux, eating sweets right before lying down can sometimes trigger upper GI discomfort or loosen the lower esophageal sphincter.
