Plain English Summary
Researchers exposed rats to 900 MHz radiofrequency radiation (the same frequency used by many cell phones) for two weeks and measured nitric oxide levels in their nasal passages. They found that EMF exposure significantly increased nitric oxide production in the nose and sinus tissues, but giving the rats melatonin prevented this increase. This suggests that cell phone radiation may trigger inflammatory responses in nasal tissues.
Why This Matters
This study adds to growing evidence that radiofrequency radiation affects biological processes even in areas we don't typically associate with EMF exposure. The nasal passages represent your body's first line of defense against airborne threats, and increased nitric oxide production signals an inflammatory response. What makes this research particularly relevant is that it used 900 MHz radiation, the same frequency band used by many GSM cell phones that millions of people hold directly against their heads daily. The fact that melatonin prevented these changes suggests the effects may be mediated through oxidative stress pathways. While this was an animal study with limitations in exposure details, it demonstrates that EMF can trigger measurable biological responses in tissues throughout the body, not just the brain.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 900 MHz
Study Details
The purpose of this study was to examine the changes in nitric oxide (NO) level in the nasal and paranasal sinus mucosa after exposure radiofrequency electromagnetic fields (EMF).
Thirty male Spraque-Dawley rats were randomly grouped as follows: EMF group (group I; n, 10), EMF gr...
The nasal and paranasal sinus mucosa NO levels of group I were significantly higher than those of th...
Exposure to EMF released by mobile phones (900 MHz) increase NO levels in the sinus and nasal mucosa.
