In working life, we encounter many people who like to work in the day, starting from the early morning hours, while they spend the bulk of the night sleeping and resting.

On the contrary, you certainly know people who spend the night at work, and show their creativity in it, and the most disturbing thing in life is that they wake up early.

It seems that whether you are day or night is determined by the time of your birth, according to a study conducted by Cleveland State University in Ohio.

The study found that people born in the early morning hours are often morning creatures who prefer to wake up early, while night time babies tend to sleep late in the morning and stay awake until late at night.

Dima Odeh spoke to Professor Ahmed Salem Bahamam, a professor at the University Center for Sleep Medicine and Research at King Saud University in Riyadh, and asked him about the scientific explanation for this study?

But to what extent is the birth clock related to determining whether a person is day or nocturnal? This question was posed by Dima Odeh to the specialist in psychology and behavioral therapy, Dr. Waddah Al-Hajjar
