RESEARCHERS from the University of Alicante say they believe that your birth month could be related to what illnesses and diseases may afflict you.
The scientists carried out the study on 30,000 people and mapped birth months to 27 chronic diseases to see if it made a difference to long-term health, and said they found there was a significant impact for some conditions.
For example men who were born in September were almost three times more likely to suffer thyroid problems than those born in January.
Their study follows one from Columbia University researchers who found similar results in a study they conducted in 2015.
