Plain English Summary
Researchers examined saliva from 86 people to see if mobile phone use affected the parotid glands (major salivary glands near the ears). They found that people who predominantly held phones on their right side had higher protein levels and saliva flow on that same side, while levels of important enzymes like amylase and lysozyme decreased. This suggests that radiofrequency radiation from phones may alter the normal function of salivary glands closest to where the phone is held.
Why This Matters
This study adds to growing evidence that EMF exposure creates measurable biological changes in tissues closest to our devices. The parotid glands sit right where we hold our phones during calls, making them prime targets for radiofrequency exposure. What's particularly telling is the side-specific pattern - changes occurred on the same side where people typically held their phones, strongly suggesting a direct relationship rather than coincidence. The decrease in protective enzymes like lysozyme and lactoferrin is concerning, as these proteins help defend against bacteria and maintain oral health. While the researchers noted the relationship wasn't statistically significant, the consistent pattern across multiple biomarkers suggests our salivary glands are responding to phone radiation in ways we're only beginning to understand.
Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
The present study aimed to evaluate the effect of mobile phone use on parotid gland salivary concentrations of protein, amylase, lipase, immunoglobulin A, lysozyme, lactoferrin, peroxidase and C-reactive protein.
Stimulated salivary samples were collected simultaneously from both parotid glands of 86 healthy vol...
Salivary flow rate and parotid gland salivary concentrations of protein were significantly higher on...
The side of dominant mobile phone use was associated with differences in salivary flow rate and parotid gland salivary concentrations, in right-dominant users. Although mobile phone use influenced salivary composition, the relationship was not significant.
