Season of birth may affect height, but not by very much, study says

Birth month may determine more than just your horoscope, it could affect how tall you are, Austrian researchers said Wednesday.

A survey they conducted on more than 507,000 Austrian soldiers showed that men born in the spring tend to be taller than those born in the autumn."Using a large human male population, we find clear evidence for a dependence of body height at age 18 on birth month," Gerhard Weber and colleagues at the University of Vienna said.

The researchers compared the heights of the soldiers measured by the Austrian Federal Army throughout a full year and found they varied periodically by about 0.23 of an inch from spring to autumn.

Weber and his team could not fully explain the link between height and birth month, but they suspected it had something to do with sunlight and the activity of the pineal gland.
