I feel dizzy when I wake up from a nap. What’s going on?

A netizen asked: In the past few days, during lunch breaks, I slept at my workstation for only 20 minutes. When I woke up, I felt a little dizzy, and everything I saw was blurry. It took a while for me to recover. What happened?

In fact, when this happens, the problem is mostly due to your sleeping position. Many people have this experience, so don't be too nervous.

First, sleeping on your stomach may compress the eyeball, causing a temporary change in the corneal curvature, and then astigmatism. This blurred vision is usually short-lived and will ease as the pressure is relieved.

Secondly, it may also be that your eyelids are not completely closed when you sleep, causing the cornea to be in contact with dry air for a long time, causing blurry vision. Usually about 15 minutes after waking up, tears will moisten the corneal epithelium and vision will slowly recover.

In short, the above two situations can be avoided by consciously adjusting your sleeping position.

However, if your vision is blurred for a long time, you should be alert. This may be caused by diseases, such as keratitis, iridocyclitis and other common eye inflammations, or glaucoma, fundus disease, etc. At this time, you should see a doctor as soon as possible and do not delay.
