This article will tell you about the influence the Sun does have on people's personalities. It also features a fun quiz for Astrology fans!

If you believe in astrology and the destiny that the stars predict for you, you might know all the reasons.

However, if you are still hesitating, we found a few scientific facts that prove there are many things, besides yourself, that influence your destiny. Take your month of birth, for example. Recent studies have shown that it can produce a small, but noticeable impact on the chance of developing a psychological issue like depression or anorexia. The month of your birth can even influence your chances of having dyslexia.

Astrology believers say the reason for this is cosmic, but the actual culprit is believed to be the Sun, or, to be more specific, the amount of sun your mother was exposed to during her pregnancy. This hypothesis is supported by the comparison of the impact the sun produces on people living in the northern and the southern hemispheres, where the peaks of sun exposure occur at the opposite time of the year.

When we are exposed to sunlight, our bodies produce vitamin D, which is vital for early brain development, hence the probable connection between the month of birth and mental health and personality traits. In the northern hemisphere, lack of sunshine and consequent lack of vitamin D also causes seasonal affective disorder, or, simply speaking, winter depression, which can be really hard to get out of.

There is another theory that is based upon the fact that the sun stimulates the conversion of melatonin – a hormone that is important for the regulation of sleep cycles — into serotonin. The level of melatonin in a future mother’s body influences the brain development of her baby and, consequently, the appearance of certain psychological traits in an adult personality. There are other theories that explain the impact the month of birth can produce upon a person’s life. So, if you do not believe in astrology, be sure that the stars — at least, the biggest one — do influence our lives.
