Study: Living Near Cell Towers Changed These People's Blood

This is part of our Study Spotlight series, where we break down the latest peer-reviewed EMF research into plain language. No hype, no dismissal — just what the science actually says.

What happens to your blood when you live steps away from a cell tower? A new study from researchers in India and Australia set out to answer that question — and the results are raising eyebrows in the EMF research community.

Published in Electromagnetic Biology and Medicine in February 2026, this study measured actual blood parameters in people living near mobile phone base stations (MPBS) in Mizoram, a state in northeastern India. Unlike many EMF studies that rely on self-reported symptoms, this one looked at objective, measurable biomarkers.

The Setup

The research team recruited two groups of volunteers:

Highly exposed group (N=50): People living within 60 meters of a cell tower
Reference group (N=51): People living more than 300 meters away

Both groups had complete blood counts (CBC) taken and were tested for two stress markers: amylase and cortisol. The researchers also measured the actual RF signal strength (power density) inside participants’ homes and recorded their daily mobile phone usage, lifestyle factors (including smoking), age, and gender.

This design is stronger than many epidemiological EMF studies because it combines objective exposure measurements with objective health outcomes — no subjective symptom questionnaires here.

What They Found

The results weren’t uniform — different white blood cell types responded differently to different exposure combinations. Here’s the breakdown:

Total White Blood Cell Count

Tower proximity contributed significantly to total leukocyte count (TLC). People living closer to towers had higher overall white blood cell counts than the reference group.

Basophils — The Allergy/Inflammation Markers

This was the most striking finding: nearly a quarter (25%) of the highly exposed group had basophil counts above clinical reference limits. Basophils are involved in allergic reactions and inflammation. Having them chronically elevated isn’t normal.

Both tower proximity and daily phone use contributed to basophil counts, along with age.

Monocytes — The Immune Surveillance Cells

Tower exposure contributed to elevated absolute monocyte counts. The researchers note that the effect of MPBS exposure on monocytes was comparable to the effect of smoking — a sobering comparison.

Lymphocytes — The Heavy Phone Use Effect

Here’s where it gets particularly concerning for younger people: over half of heavy phone users (4-6 hours daily) had lymphocyte counts above clinical reference limits. Most of these individuals were under 30 years old.

Lymphocytes are the workhorses of your adaptive immune system — they include T cells, B cells, and natural killer cells. Having them chronically elevated suggests the immune system is in a state of ongoing activation.

Stress Hormones — No Effect

Interestingly, neither tower proximity nor phone use contributed to amylase or cortisol levels. Only smoking and age affected these stress markers. This suggests the blood changes aren’t driven by psychological stress about living near towers.

Why This Matters

This study is notable for several reasons:

1. Objective measurements on both sides. They measured actual RF power density in homes AND used lab blood tests — not symptom questionnaires. This eliminates the nocebo effect argument that haunts many EMF health studies.

2. The dose-response pattern. Different types and levels of exposure (tower proximity vs. phone use vs. combined) affected different cell types. This isn’t what you’d expect from a random or confounded result — it suggests specific biological mechanisms.

3. The monocyte-smoking comparison. Finding that cell tower exposure affects monocytes at a level comparable to smoking’s effect is a powerful data point. Nobody would argue smoking doesn’t affect blood parameters.

4. The youth vulnerability signal. Young heavy phone users showing the highest lymphocyte elevations aligns with the growing concern about children’s EMF exposure — younger tissues may be more responsive.

The Caveats

Let’s be honest about the limitations:

Small sample size. With 50 and 51 participants, this is a pilot-scale study. Larger studies are needed to confirm these patterns.

Cross-sectional design. This is a snapshot, not a longitudinal study. We can’t be certain the blood changes were caused by the exposure rather than correlated with it. People who live very close to cell towers may differ from those who don’t in ways the researchers didn’t capture.

Single location. Mizoram has specific demographics, diet, and environmental conditions. Results may not generalize to other populations.

Journal reputation. Electromagnetic Biology and Medicine publishes legitimate research but has a lower impact factor than journals like Environmental Health Perspectives or JAMA. The findings need replication in higher-profile venues.

ORSAA involvement. Several co-authors are from ORSAA (Oceania Radiofrequency Scientific Advisory Association), which has advocated for stricter EMF limits. This doesn’t invalidate the data, but readers should know the researchers’ perspective.

The Bigger Picture

This study fits into a growing body of research examining whether chronic, low-level RF exposure affects immune function. Previous studies have found similar patterns:

Altered blood parameters in people living near base stations (several earlier studies from Egypt, Iran, and Saudi Arabia)
Immune system markers affected by occupational RF exposure (though operating room workers showed no effects below ICNIRP limits)
The ICBE-EMF commission’s argument that current safety limits don’t account for chronic low-level biological effects

At the same time, other studies show that typical exposure levels produce minimal physical effects, and the NTP Lite replication found no cancer in animals exposed to cell phone-level RF.

The science genuinely isn’t settled. Studies like this one add data points suggesting biological effects exist at typical environmental levels, while others suggest the opposite. What’s needed is larger, well-funded, longitudinal studies — and that’s exactly what the stalled WHO review process is supposed to deliver.

What You Can Do

If you live near a cell tower, this study doesn’t mean you’re in danger — but it does suggest that proximity matters:

Check your exposure. Use EMF Radar’s address search to see how many towers are near your home and their distances.
Reduce phone SAR. Use speakerphone or earbuds for calls — distance dramatically reduces exposure.
Know your blood baseline. If you live very close to a tower (<60m), consider asking your doctor for a CBC at your next checkup. It’s a routine, inexpensive test.
Sign up for tower alerts to know when new towers are proposed near your home.
