Your skin down there has an invisible shield that keeps irritants out and moisture in. But at night, that shield gets thin and cracked, just like chapped lips in winter.
The moment you lie down, your body heat rises, your doona traps the warmth, and those tiny cracks get exposed to heat, friction, and dryness, all at once.
And the chemical that causes itching? It peaks at night. The one that calms it down? It completely drops.
That’s exactly why you might feel fine at 6pm, but find yourself wide awake and scratching at 2am.
