High blood pressure? Blame the weather
What was the weather like in the year you were born? It could be a guide to whether or not you'll have high blood pressure.
People who were born during hot, dry years seem to have higher blood pressures, a study in the American Journal of Epidemiology indicates. This could be because of dehydration in infancy.
'Animal studies suggest that severe dehydration in infancy results in greater sodium retention and a taste for salty foods throughout life,' Dr. Debbie Lawlor, of the University of Bristol told Reuters.
Once upon a time this might have helped human beings survive. Now it is simply like to lead to high blood pressure.
Lawlor's studylooked at nearly 4000 randomly selected UK women born in the early 20th century. A high average summer temperature in the first year of life tended to lead to a higher systolic (the upper figure) blood pressure in adulthood. Conversely, higher average summer rainfall was linked to a lower adult systolic blood pressure.
The researchers also found that those who experienced the hottest and driest summers in the first year of life were more likely to have suffered severe infant diarrhea and dehydration.
The planet is getting hotter so does that mean that high blood pressure will be another result of global warming?
