How it's used
This term reflects the traditional Chinese medical belief that the ground emits a cold or damp energy that can penetrate the body. It is specifically used when someone wakes up feeling stiff, sore, or unwell after sleeping on a hard or cold floor. You will mostly hear it from older generations who emphasize the importance of using a mattress or bed frame to stay elevated.
Examples
Be careful of getting sick from sleeping on the floor.
He slept on the floor last night and now his back hurts.

Common mistake
Do not confuse this with simply sleeping on the floor, which is 瞓地下. 打地氣 specifically refers to the negative physical symptoms that follow, not the act of sleeping itself.
