Mobile phones are people's closest "partners", some even sleep next to bed, but such a simple move can pose serious health risks.
A British study has shown that an all-dark sleep environment helps the body produce a hormone called melatonin, which boosts metabolism and improves sleep quality. But if you bring your phone into the bedroom or charge it in the bedroom, the tablet computer recharges it. The blue light will affect the secretion of melatonin, lead to metabolic imbalance, causing obesity, high blood pressure, diabetes, cancer and other diseases.
At the same time, the electromagnetic radiation of mobile phone is harmful to human head, it may affect the central nervous system, cause headache, dizziness, insomnia, dreamy and alopecia, but also affect deep sleep and reduce the quality of sleep.
In the standby state, the electromagnetic radiation of the mobile phone is 2.3 m#china_person0#, but when connected, it increases to 3.4. In addition, the electromagnetic radiation of the mobile phone at the distance of 5 cm, 10 cm or 15 cm from the mobile phone is 1 0. 5 and 0. 3, respectively. Thus, it can be seen that, The radiation value of mobile phone is different from that of standby and turn on, and the farther away it is, the smaller the electromagnetic radiation is.
Therefore, it is recommended that you turn off your cell phone when you sleep, and if you can't, don't bring it into your bedroom, let alone charge it in your bedroom or put it next to your pillow.
