The chance of developing schizophrenia may be directly linked to how sunny it was in the months before a person's birth, research suggests.

A lack of sunlight can lead to vitamin D deficiency, which scientists believe could alter the development of a child's brain in the womb. according to an article in the New Scientist in 2002, research suggests people who develop schizophrenia in Europe and North America are more likely to be born in the spring.

A psychiatrist at the Queensland Centre of Schizophrenia Research in Brisbane, Australia, made similar findings, suggesting a lack of UV light during pregnancy tips the balance towards schizophrenia in genetically susceptible people.
