This month wants to use debit alert to kill me. The previous months would tear ACL.
But I'm looking at the brighter side. My dad used to say, "be thankful for dirty plates, it is only because there was food to eat that the plates are dirty." I dread the debits but I'm thankful regardless because na who get money for account dey get debit alert.
Your regular 3AM wake-up is a counter-regulatory hormonal response to nocturnal hypoglycemia.
Blood sugar drops.
The hypothalamus detects it.
The adrenal glands release cortisol and epinephrine.
The liver dumps glucose. Brain saved from starvation but now your heart is racing and you are wide awake.
Not insomnia. Not anxiety. Neuroendocrinology.
The exact neuroendocrinology behind why you jolt awake at 3 AM and why it isn't just insomnia.👇
• The Blood Sugar Drop: While you sleep, your brain is still burning glucose. By 3 AM, if you haven't eaten in 8+ hours, your blood sugar hits its absolute lowest point (hypoglycemia).
• The Alarm Bell: Your brain senses this drop in fuel as a literal survival threat.
To rapidly bring your blood sugar back up, your brain triggers your adrenal glands to dump two counter-regulatory hormones into your bloodstream:
-Cortisol and Adrenaline (Epinephrine).
The Side Effect: Cortisol and Adrenaline are your fight or flight hormones. They successfully trigger your liver to release stored glucose, saving your brain from starvation.
• The Awakening: But because your blood is now suddenly flooded with adrenaline, your heart rate spikes, your core temperature rises and you jolt completely awake.
• How to Prevent It:
-The Pre-Sleep Fuel: Eat a small, high-protein or complex-fat snack 30 minutes before bed (like a spoonful of peanut butter or a handful of almonds). This provides a slow-burning glucose drip that keeps your blood sugar stable until morning.
-Avoid the Alcohol Trap: A nightcap might help you fall asleep, but alcohol actively blocks your liver from releasing stored glucose (gluconeogenesis) overnight, guaranteeing a 3 AM cortisol spike.
