My boyfriend and I had a wonderful dinner.

After we ate, he hugged me and brought me to his bed.

He got a heatpad out, and placed it on my stomach while cuddling me.

I fell asleep in less than 5 minutes.

I typically sleep after 10-15 minutes.

Why did the heatpad knock me out so quickly?

Edit 1: Going to perform a control test (headpad minus the boyfriend) in a few weeks: https://lemmy.world/comment/17421938
