Why just wake up sometimes the eyes will swell? How can I reduce swelling?

I woke up in the morning and found my eyes swollen. Maybe I drank too much water before going to bed the night before. Or catch cold and get wet when sleeping. It was very hot for a while, so I slept directly on the floor of the dormitory. As a result, I woke up the next morning with swollen eyes and ankles. Later, the elders said that it was caused by too much moisture on the floor. Therefore, the time to clean the floor should not be too close to the time to sleep (especially in summer, because the temperature is relatively high, most people will choose to sprinkle some water indoors regularly or take a lunch break after cleaning the floor, so it will be relatively cool when sleeping), because after cleaning the floor, the water on the surface will always evaporate, and sleeping at this time is not good for the human body.

It is recommended not to drink water before going to bed. Or you can drink a glass of water an hour before going to bed. Because of the sleep the next night, the body will be extremely short of water. So you can drink a cup of warm water an hour or half before going to bed.

Introduce a quick solution. Is after waking up. If your eyes are swollen. You can take a stainless steel spoon. Or put the spoon in the refrigerator for a while. After taking it out, gently press it on your eyes with the smooth part of the back of the spoon for a few minutes. Can relieve edema.
