People Are Putting Aluminum Foil Under Their Pillow Before Bed — Here’s What Actually Happens

Aluminum Foil Under Your Pillow: Sleep Hack or Myth?

• What it is: Placing a sheet of aluminum foil under your pillow before bed.

• Origins: Old folk remedies + viral social media hacks promising better sleep and pain relief.

• Claims:

  • Better sleep quality

  • Reduced headaches, neck, or shoulder pain

  • Feeling calmer or “lighter” in the morning

• Science says: No evidence foil directly improves sleep — benefits likely from placebo or slight pillow firmness change.

• Practical effect: Can subtly improve pillow support and comfort.

• Safety tips:

  • Use a flat, smooth sheet

  • Avoid sharp folds or heat

  • Not a replacement for medical care or ergonomic pillows

• What it won’t do: Detox your body, block radiation, cure chronic pain, or replace professional advice.

• Takeaway: It’s a harmless, quirky ritual. If it helps you relax, that’s enough to improve sleep — but don’t expect magic.
