Exposure to 5G-NR electromagnetic fields affects larval development of Aedes aegypti mosquito

De Borre E, De Massia C, Boone MN, Müller P, Thielens A · 2025

Researchers exposed Aedes aegypti mosquito larvae to 3.6 GHz radiation (5G frequency) for 5 days and found that even moderate exposure levels slowed development, while higher levels caused dielectric heating that changed development timing and adult size. The effects were more pronounced in nutritionally stressed larvae, suggesting RF-EMF exposure compounds other environmental stressors.

Migdal P et al. · 2024

Researchers exposed honey bees to radiofrequency electromagnetic fields at three different intensities (12, 28, and 61 V/m) for varying durations and analyzed their blood chemistry. They found that EMF exposure significantly altered key nutritional markers including proteins, glucose, and triglycerides in the bees' hemolymph (blood). The study suggests that RF fields disrupt honey bee nutrition, which could have long-term health consequences for these critical pollinators.

Lai H, Levitt B. (2023) Cellular and molecular effects of non-ionizing electromagnetic fields

Lai H, Levitt B · 2023

Researchers Lai and Levitt propose that cells respond to electromagnetic fields through a universal 'cellular stress response' mechanism, the same way they react to heat or toxins. This response can either help or harm health depending on exposure intensity and duration. The theory explains why EMF effects are often inconsistent and why some studies show benefits while others show harm.
