Wi-Fi exposure reduced elastic fiber density at both 9 and 14 days, increased collagen density at day 9, and decreased it at day 14.

Plain English Summary

Summary written for general audiences

Researchers continuously exposed chicken embryos to Wi-Fi radiation at 2.4 GHz and 300 µW/m² for 9 and 14 embryonic days. Standard haematoxylin and eosin staining showed no notable differences in large blood vessel structure between exposed and control groups. Special staining methods revealed an adverse effect of Wi-Fi on the fibrous elements of the vessel wall. Elastic fiber optical density decreased significantly at both 9 and 14 embryonic days, while collagen fiber optical density increased at day 9 and decreased at day 14.

Why This Matters

The authors concluded that the results support the hypothesis that Wi-Fi could affect the fibrous elements of the large vessel wall. They suggested this may play a role in the development of cardiovascular disorders.
