U pinch your nose close your mouh and try to force air out of u that's what I do
It is to test pressure inside the eye.
When your eyes water, they drain to your nose down to your stomach via a drainage canal, from your eye to your nose - this is kind of like your body recycling it's fluids. The reason your eyes might, "bubble" when you blow your nose is because air is going in reverse from the canal to the eye.
This is normal; the nasal passages, mouth and eyes are all connected.
why does ac blow warm air? why does ac blow warm air?
An air conditioner blows out heat
Yes. There's a canal that connects your nasal cavity to your eyes; that canal drains tears from your eyes (that's why your nose runs when you cry). So if you block your nose and blow hard, the air will come through those canals and out the drainage ducts for tears in your lower eyelid.
if the heater does not blow out warm air change the setting.
Hot air because it is blow out the hot air from the inside of the laptop.
i hav the same problem
No. A blow dryer sucks in air, heat/cools it, then blows it back out again. Without atmosphere, there is no air, and without air, there is no blow dryer.
If it does blow just not cold air you should see if it needs to be recharged
It doesn't really blow it out it just warms the cold air.
