How do mobile affects human health?
The effects of mobile phone radiation on human health are still being studied and debated. While some studies have suggested that long-term exposure to radiofrequency (RF) radiation from mobile phones may increase the risk of certain types of cancer, such as brain tumors, the evidence is not yet clear. The World Health Organization (WHO) classifies RF radiation as a possible human carcinogen, but the levels emitted by mobile phones are considered to be low and not a significant health concern. However, there are some other potential health effects associated with mobile phone use that have been identified: Headaches and dizziness: Some people may experience headaches or dizziness when using mobile phones, particularly if they use them for long periods of time. Sleep disruption: The blue light emitted by mobile phones can affect the body's production of melatonin, a hormone that regulates sleep. This can lead to insomnia and other sleep disorders. Eye strain: Prolonged use of mobile phones can cause eye strain, dry eyes, and blurred vision. Texting thumb: Repetitive use of mobile phones can lead to pain and inflammation in the thumbs and fingers, known as texting thumb. Increased stress: Constantly checking and responding to messages and notifications on mobile phones can increase stress levels. my recommendation to protect yourself against radiation: ʜᴛᴛᴘꜱ://ʙɪᴛ.ʟʏ/ᴇᴍꜰᴅᴇꜰᴇɴᴅᴇʀ
