Longevity expert Diego Suárez posted a viral video warning that sleeping next to a mobile phone prevents brain regeneration, but his cited evidence is unrelated.
An inspection of the four PubMed scientific reference numbers listed alongside his TikTok publication reveals that none of the studies involve mobile phones, radiofrequency radiation, or nocturnal rest.
In the video published on January 8, 2026, Suárez stated that more than 25 percent of people exposed to nighttime wireless signals develop severe sleep disorders. He claimed that the human body requires darkness, silence, and an absence of radiation to repair itself, arguing that keeping a phone by the bed alters brainwaves and suppresses melatonin production.
By August 12, 2026, the post had accumulated 497,900 views, 11,200 likes, 115 comments, and 16,700 shares on TikTok, reflecting widespread interest in sleep advice across social media.
Analysis of the Four PubMed Citations
To support his assertions, Suárez provided four PubMed PMID identification numbers, which are unique numerical codes used by the United States National Library of Medicine to index peer-reviewed biomedical research. However, an examination of the official database entries shows that the reference numbers correspond to topics completely unrelated to sleep hygiene or mobile devices.
The first two citations, PMID 14564853 and PMID 15010236, lead to scientific papers covering computer planning for work shift schedules and reading comprehension skills in children diagnosed with hydrocephalus, a neurological condition involving fluid buildup in the brain. Neither study investigates smartphones, radiofrequencies, night rest, or screen night modes.
The remaining two numbers are similarly disconnected from sleep science. PMID 24047965 details therapeutic treatments for benign paroxysmal positional vertigo, an inner ear disorder causing brief episodes of dizziness. PMID 21745571 evaluates conditioned reinforcement associated with oxycodone, a prescription opioid medication, in laboratory rats.
Official records from the United States National Library of Medicine confirm that all four references are entirely foreign to the video claims. The citations provide zero proof that charging or storing a mobile phone near a bed causes sleep disorders or blocks brain regeneration.
Scientific Evidence on Screen Light and Radiofrequency
While the video claims lack empirical support, established scientific research does highlight distinct issues associated with active nighttime screen use. A controlled study published in the Proceedings of the National Academy of Sciences compared 12 adults reading for four hours on a light-emitting e-reader screen against reading a printed book, across five nights per condition.
The trial demonstrated that reading on a screen reduced evening melatonin secretion by approximately 55 percent, delayed the body internal circadian clock by more than an hour and a half, and increased the time required to fall asleep by about ten minutes. Researchers noted that while screen night filters may lower visual intensity, they do not replace stopping device use before sleep.
Scientists emphasize that active engagement with a bright screen for hours is fundamentally different from leaving an idle mobile phone resting on a nightstand. Additionally, a 2024 systematic review conducted for the World Health Organization evaluation program found no evidence that experimental exposure to radiofrequency electromagnetic fields caused self-reported sleep disturbances among participants.
Experts note that visible screen light, radiofrequency signals from cellular connections, and magnetic induction fields generated by wireless charging represent distinct physical phenomena requiring separate scientific evaluation.
Device Charging Protocols and Sleep Environment
Keeping a mobile phone near the bed can cause several practical problems at bedtime, including lengthening screen time, illuminating the room, generating notification alerts, and heating up while charging. Distinguishing between physical device presence and active usage helps clarify effective sleep habits.
Moving a phone out of the bedroom can support healthy sleep routines by eliminating nighttime distractions and keeping the room dark. Utilizing an independent alarm clock also removes the excuse of keeping a smartphone within arm reach during the night.
For individuals who charge their phones overnight, firefighter safety guidelines recommend placing the device on a firm, well-ventilated surface away from pillows, blankets, and flammable fabrics to prevent thermal risks. Heating during charging is a physical safety issue unrelated to electromagnetic radiation.
Health professionals stress that no specific physical distance between a sleeper and a phone acts as a standalone guarantee for quality sleep. While removing a phone from the bedroom is a simple practical habit, chronic or persistent sleep disorders require formal evaluation by healthcare professionals rather than relying on viral social media diagnosis.
