Dr. Karan Raj is building a career as a TikToker, sharing fun science news and medical facts in an unconventional way

A few weeks ago, the British shocked millions of subscribers with an optical illusion, proving that our lives are a lie.

Just recently, the doctor brought up the topic of lack of sleep on his blog. It turns out that a person does not always realize how much his body needs sleep. Fortunately, there is a special test that helps you quickly find out.

In the video, Raj seems to show only a flashing picture. If you've thought that, though, we've got some bad news - you should definitely go to bed.

Each time the screen flashes, an image appears afterwards that is slightly different from the previous one.

It seems that the differences in the photos are too obvious to notice, but this is not the case, especially if you slept for three hours.

With lack of sleep, the concentration of attention decreases so much that the brain is simply not able to follow such small things as the color of the bus, etc.
