Cuttack: There is ongoing debate about the health effects of smartphone radiation and blue light exposure, especially when using phones late at night. While research has not conclusively proven that keeping a phone near the head while sleeping directly causes brain cancer, some studies suggest that prolonged exposure to radiofrequency radiation (RF) from mobile phones could have potential health risks.
Potential Health Risks of Using Phones at Night
1. Disrupts Sleep: The blue light from screens can interfere with melatonin production, a hormone that regulates sleep, leading to insomnia or poor sleep quality.
2. Mental Health Issues: Excessive phone use, especially at night, has been linked to increased stress, anxiety, and depression.
3. Cognitive Impairment: Poor sleep due to prolonged screen exposure may negatively impact memory, focus, and cognitive function over time.
4. Potential Cancer Risk: Some studies suggest that long-term exposure to RF radiation from smartphones might increase the risk of brain cancer, though this is still a topic of scientific debate.
5. Male Fertility Issues: RF radiation has been linked to reduced sperm quality in men, potentially affecting reproductive health.
Precautionary Measures
Avoid keeping your phone under your pillow or close to your head while sleeping.
Use “Night Mode” or “Blue Light Filter” on your phone to reduce blue light exposure.
Limit screen time before bed—try to stop using electronic devices at least 30–60 minutes before sleeping.
Keep your phone on airplane mode or at least a few feet away from your bed while sleeping.
Use wired earphones or speaker mode instead of holding the phone close to your ear for long periods.
While there is no definitive proof that phone use at night directly causes cancer, it is always a good idea to take precautionary measures for better sleep and overall health.
