Men who used their phone more than 20 times a day had a median sperm concentration about a fifth lower, but that is a correlation, and the link weakened over the years as networks moved from 2G towards 4G. The evidence is early: signals, not answers.Wed, 14 Oct 2026 00:00:00 GMTphone in pocket sperm countdoes keeping phone in pocket affect fertilitydoes phone radiation affect spermphone in pocket fertilityDo AirPods cause cancer? What the studies actually say about your earbudshttps://belowheadline.com/do-airpods-cause-cancer/https://belowheadline.com/do-airpods-cause-cancer/There is no good evidence that the radio waves from AirPods or other Bluetooth earbuds cause cancer: they transmit at around 10 milliwatts or less, far below a phone, and tested headsets sit well under safety limits. The real, settled risk is volume. Loud listening, for long enough, permanently damages the hair cells in your inner ear.Wed, 14 Oct 2026 00:00:00 GMTdo airpods cause cancerare airpods safe radiationare airpods safebluetooth headphones radiationcan earbuds damage your hearingDoes 5G cause cancer? What the studies actually sayhttps://belowheadline.com/does-5g-cause-cancer/https://belowheadline.com/does-5g-cause-cancer/No. At the levels people are actually exposed to, the evidence says 5G does not cause cancer: a 2024 WHO-commissioned review of 63 studies found that mobile phone use likely does not raise the risk of brain or other head tumours, and 5G radio waves carry far too little energy per photon to damage DNA. The scary rat study is real, but it used old 2G and 3G signals at whole-body doses no phone user gets, and the exposed male rats lived longer.Wed, 14 Oct 2026 00:00:00 GMTdoes 5g cause canceris 5g radiation dangerousis 5g safe5g health effects
