Gao et al. 2025 study provides evidence supporting a causal relationship between the duration of mobile phone use and aneurysmal subarachnoid hemorrhage. Excessive mobile phone use may increase the risk life-threatening brain bleed caused by a ruptured aneurysm in the brain's subarachnoid space.

A 2025 study by Xiao et al. on a cohort of 4285 US adolescents found that over a 4-year period, 31.3% had increased social media addiction and 24.6% had increased mobile phone addiction. High and increasing rates of addictive screen use were both associated with suicidal behaviour and ideations and poorer mental health.

Hypothesis: ultrasonography can document dynamic in vivo rouleaux formation due to mobile phone exposure🔗

Written on 25 February 2025. Posted in Science.

A 2025 study by Brown et al. found that in a living person exposed closely to cell phone radiation, red blood cells begin to clump together and form clumps resembling stacks of coins. This effect in vivo can cause a number of health problems as clumped blood cells flow less easily and can impact oxygen delivery in the body.

A summary of case reports over a two-year period found that 16 of the study persons developed microwave syndrome or other serious health symptoms after 5G base stations were installed around their homes. Most people were able to move to another home without 5G. Their symptoms were reduced or disappeared.

S. Gulati et al (2024) did not find significant DNA damage and/or oxidative stress due to being near mobile phone base stations (MPBS). However, chromosomal aberrations, cytogenetic damage, higher levels of lipid peroxidation and oxidative DNA lesions significantly increased in residents with higher exposure to RF-EMF from MPBS.

In Michael Kundi et al.'s (2024) study, participants received UMTS signal doses with a SAR of 0.1-1.6 W/kg via headsets for 2 hours on 5 consecutive days. Buccal mucosa and micronucleated cells collected from both cheeks before and 3 weeks after exposure showed clear evidence of cell cycle disruption and cytotoxicity.

Detrimental impact of cell phone radiation on sperm DNA integrity🔗

A 2023 Iranian study concluded that the radiation from mobile phones can cause reduced motility, morphological changes, acrosome disorders, and ultimately, damage to the nucleus and the genetic material due to oxidative stress. The sperm genome damage can lead to infertility and endanger the reproductive health of offspring.

Increasing sleep disorders among Swedish children🔗

In the last fifteen years, sleep disorders among Swedish children aged 0-19 have increased significantly, as has the prescription of sleeping pills or sedatives. The exposure to radiation from wireless technologies has increased enormously over the same period.

During 2023 and January 2024, seven case studies have been published in scientific journals on the health effects of exposure to real 5G radiation from base stations. The studies, probably the first in the world to study the health impacts of real 5G exposure, all show that 5G is harmful to human health.

Electromagnetic Fields – Do They Pose a Cardiovascular Risk?🔗

Slovakian 2023 study revealed discrete abnormalities of complex cardiac autonomic regulation indexed by HRV measures dependent on the effects of 4G and Wi-Fi networks. It seems that direct exposure to high radiofrequency EMF may be associated with a higher risk of cardiovascular complications already in healthy youth.
