there is no scientific evidence to suggest that sleeping next to a phone in airplane mode has any adverse effects on the brain. Airplane mode disables all wireless communication features of a mobile device, including cellular, Wi-Fi, and Bluetooth connections. As a result, the phone emits significantly less electromagnetic radiation in airplane mode compared to when it is in normal mode.
Electromagnetic radiation emitted by mobile phones and other electronic devices is a topic of ongoing research and debate among scientists and health experts. The majority of studies conducted so far have not found any conclusive evidence linking exposure to radiofrequency (RF) electromagnetic fields from mobile phones to adverse health effects.
However, given the rapid advancements in technology and the continuous evolution of scientific knowledge, it's always a good idea to stay informed about the latest research findings and guidelines related to mobile phone usage. Additionally, if you have specific concerns about your health or sleep quality, it's best to consult with a medical professional who can provide personalized advice and recommendations based on your individual circumstances.
