The study found that the risk of miscarriage at the end of August is 31% higher than at the end of February. It was conducted by scientists from Boston University.
American researchers have shown that expectant mothers from North America have a significantly higher risk of early miscarriage in the summer than in the winter months. For example, at the end of August it is 44% higher than in February. An early miscarriage is when a pregnancy is terminated within the first 8 weeks after conception.

The study found that in any week of pregnancy, the risk of miscarriage at the end of August is still 31% higher than at the end of February. And every time scientists note seasonal changes in the likelihood of this unfortunate event, they give clues about their causes. There is a need to delve deeper into understanding which types of effects on pregnancy are more common in the summer and how they affect the risk of miscarriage. It is possible that we are talking about the influence of high temperature and sunlight.
