Study: Having kids could reduce blood pressure

January 18, 2010 Scientists had 200 married couples wear blood pressure monitors for 24 hours.

Those with children, particularly mothers, had lower blood pressure than those who were childless.

Hormonal changes from pregnancy and childbirth may explain the differences.

Also, many parents will agree, children enrich and fulfill their lives, which may also explain the lower readings.

Complete results are available in the journal Annals of Internal Medicine.
