Do you like to play with your phone before bed? Haven’t thought that it would be harmful to play with a mobile phone before going to bed? Today, the disease control gentleman will come to popularize with you, the harm of this behavior:
Effect on the eyes
The study found that the use of mobile phones in the dark will cause damage to the retina. The main reasons are:
In low light environment, the pupil naturally enlarges, and the visual quality such as sharpness and contrast will decrease. Completely relying on the lens to adjust itself to see things clearly, the burden on the adjustment system is increased, and it is easy to cause eye fatigue. Repeated and long-term visual fatigue can easily lead to retinal damage, deepening myopia, and induce or aggravate eye lesions;
Mobile phone The blue light and infrared light emitted by the screen can easily cause photochemical damage to the retina.
In addition, the use of mobile phones in the dark may lead to the occurrence of dry eye syndrome. When using a mobile phone, due to too much attention, the number of blinks per minute decreases. In addition, the brightness of the mobile phone screen after turning off the light is more dazzling, resulting in a decrease in tear secretion and changes in tear composition, and even more serious shedding of the corneal epithelium.
Effects on cervical spine and muscles
The human cervical spine has a normal physiological curvature. Playing with mobile phones, whether it is semi-recumbent, side-lying, or prone, will have adverse effects on our cervical spine, resulting in excessive anterior bowing of the cervical spine, causing strain and some intervertebral facet joint disorders, resulting in low back pain, neck pain and other problems.
When lying on the side and playing with the mobile phone, the trapezius muscle needs to maintain a shrugging posture and is always in a state of exertion. In the long run, it is easy to cause the posture problem of round shoulders and hunchback, and if you maintain a bad posture for a long time, the muscles are prone to fatigue and stiffness. It can also cause hand numbness and other symptoms.
Effects on sleep
Playing with your phone before bed can affect sleep quality. Playing with mobile phones before going to bed keeps the brain in a state of concentration, people often take longer to fall asleep, and the time for deep sleep is correspondingly reduced. Studies have shown that short-wave blue light emitted by light-emitting electronic products such as mobile phones can inhibit the secretion and synthesis of melatonin, which directly affects the quality of sleep. At the same time, it also indirectly affects sleep quality by disrupting emotional balance, allowing adolescents to experience more negative emotions and less positive emotions. Studies have shown that the longer the mobile phone use before bed, the greater the negative impact on sleep, and the more negative subjective emotions.
So for the sake of health, it is best not to play mobile phones before going to bed at night. It is really impossible to restrain playing with mobile phones. It is recommended to take the following methods to minimize the damage:
1) Turn on the lights when playing with mobile phones;
2 ) Turn down the brightness of the mobile phone screen;
3) Do not lie on your side or prone to play with your mobile phone. If you have to lie down, you can lie on your back, but it is not recommended for too long.
I hope you will put your mobile phone far away from the head of the bed before going to bed, set an alarm, free your brain, drink a glass of hot milk, relax your body and mind, and have a sweet dream !
