A research report published by Dr. Lawlor and colleagues from the University of Bristol in the "American Journal of Epidemiology" suggests that individuals born in hot and dry years may be more prone to hypertension.
The report states, "Results from animal experiments indicate that severe dehydration during infancy can lead to an increased ability to retain sodium, resulting in a lifelong preference for salty foods." The side effect of this is elevated blood pressure.
To investigate the relationship between climatic conditions during infancy and the development of hypertension in adulthood, Dr. Lawlor's research team randomly selected 3,964 British women born in the early 20th century for a survey. The survey found that compared to those who experienced cool and wet summers in their first year of life, those who endured hot and dry summers in their first year were more likely to suffer from severe diarrhea and dehydration during infancy.
Additionally, if the average summer temperature in the first year of life was mild, systolic blood pressure in adulthood tended to be higher; conversely, if the first summer was rainy, systolic blood pressure in adulthood was lower.
Dr. Lawlor and his team ultimately concluded that if the above hypothesis holds true, it would have significant implications for public health, emphasizing the importance of preventing infant dehydration. This is not only crucial for short-term health issues but also greatly beneficial for maintaining long-term cardiovascular health.
