The San Francisco 49ers are far and away the most injured team in the NFL over the last decade. This isn’t based on the eye test, either, but statistical fact.
In a study put together by Peter Cowan, the San Francisco 49ers were found to statistically be the most injured team in the NFL since 2014, and by some distance, too. Cowan is the founder of “Sunlight is Life (software tools for light and sun exposure optimization) and Living Energy Wellness, where I practice as a board-certified quantum biology practitioner,” according to his website.
According to Cowan’s data, since moving to Levi’s Stadium in 2014, the 49ers are: top-5 in Adjusted Games Lost for 10 of 11 seasons; have had 7-8 full Achilles/patellar ruptures compared to the league average of two-to-three per year TOTAL; 40+ major hamstring/calf tears; and a pattern of high-ankle syndesmosis injuries every single year.”
Cowan says that “no other franchise comes close” to the 49ers’ recent injury history, and the reason for that may have to do with the fact that their practice field is located next to a electrical substation; an electrical substation that emits “low-frequency electromagnetic fields,” which can “degrade collagen, weaken tendons, and cause soft-tissue damage at levels regulators call ‘safe.'”

“On December 1, 2025, I walked to the northeast corner of the 49ers’ Marie P. DeBartolo Sports Center practice fields in Santa Clara—a little over 100 yards from Silicon Valley Power’s Mission Substation (the city-owned 60 kV facility that replaced parts of the old Tasman Substation during stadium construction)—and turned on my gaussmeter,” Cowen explained on his SubStack.
“At 11:00 a.m. on a quiet Monday (far from peak load), it read 8.5+ milligauss (to put that in perspective, the average background level in a typical American home or office is usually between 0.5 and 3.0 mG). One hundred yards closer, in the facilities where players lift, watch film, and recover, the fields could be several times higher: potentially 13–21 mG on a normal day, spiking even higher during peak grid demand—like evening practices or hot/cold weather when more electricity flows through the substation.”
Chronic ELF exposure is degrading the collagen integrity in the players tendons, ligaments, and muscle-tendon junctions.
The damage is subtle, until a routine cut or block ends in catastrophic rupture.
The injury pattern matches the biological fingerprint of prolonged ELF…
