Monsoon doesn't seem to be a good time to get pregnant if you live in Mumbai. New research in the tropical coastal city, which has relatively uniform meteorological variables throughout the year except in monsoon, seems to suggest so1.

Compiling medical records of close to 30,000 pregnancies from a maternity ward in Mumbai, the study concludes that the incidence of eclampsia — a form of blood poisoning during pregnancy — was significantly higher in monsoon, when the weather is cooler and humid with a lower barometric pressure than the rest of the year. Eclampsia is characterized by the presence of albumin in urine, hypertension and convulsions.

"This strengthens the association of low temperature and high humidity with the trigger for eclampsia," says researcher Vidya Subramaniam.
