Recently, there has been a lot of debate on whether to turn off Wi-Fi at night to protect brain health. Some opinions are concerned that radio frequency signals (RF) issued from the coordinates can disrupt sleep or damage nerve function, according to IndianExpress.
Dr Praveen Gupta, President of the International Neurological and Spine Institute of Marengo Asia (MAIINS), Marengo Asia Hospital, Gurugram (India), commented: Most of the worrying studies were conducted on animals and have not been proven in humans. More in-depth research is needed to determine the real impact of Wi-Fi on human health.
According to the explanation, Wi-Fi uses uniolated radio waves, much weaker than X-ray or CT radiation. This wave is not strong enough to break down brain cells or change DNA. Large-scale studies have so far not found a direct link between Wi-Fi and diseases such as brain tumors, memory loss or neurodegeneration.
Some small studies have shown that Wi-Fi can have a slight impact on brain wave activity in deep sleep, but these changes are insignificant and have no clinical significance.
In fact, poor sleep quality often comes from stress, the habit of using electronic devices before bed, or sleep disturbances, not from Wi-Fi signals.
Notably, many people are still concerned that Wi-Fi can cause cancer or have a negative impact on pregnant women. However, the World Health Organization (WHO) and many international studies have confirmed that there is no causative link between exposure to Wi-Fi and cancer development.
Modern medical equipment such as heart rate machines and hearing aids are also designed to avoid interference from RF waves, ensuring safety when used.
Experts say that the most important factor to protect the brain is a healthy sleep routine, avoiding phone screens before bed, maintaining a quiet space, evening and a moderate rest schedule.
Turning off Wi-Fi at night can indirectly help, not because Wi-Fi waves are dangerous, but because it limits the temptation of the internet and helps users sleep better.
