We've grown accustomed to lying in bed before sleep, scrolling through social media, messaging on WeChat, or playing games... yet we hesitate to fall asleep immediately.While phones bring us much enjoyment, are you aware of the health risks of using them before bed?
1. Disrupts Your Body Clock
Using phones, tablets, or other light-emitting devices in bed for over an hour reduces melatonin production by approximately 22%.Once melatonin production is suppressed to this extent, your physiological cycle becomes disrupted. The direct consequence is that you remain in light sleep, or even experience significantly reduced sleep duration. In other words, after an hour of phone use, you might end up staying up another three hours because you simply can't fall asleep.
2. Chronic Strain
Excessive neck drooping, unnatural body curvature, and increasingly forward-tilted necks cause the sternocleidomastoid muscles to stretch forward continuously. Over time, this leads to chronic congestion, potentially compressing the vertebral arteries and triggering cervical spondylosis, resulting in chronic strain.
3. Impact on Vision
Lying on your side exerts the greatest pressure on your eyes. Continuing this habit for less than a month can cause vision discrepancies between your eyes (explaining why some people need different prescriptions for each eye despite being born with identical vision—some prefer lying sideways to use phones, read novels, or view comics).The pillow's pressure on the eyes reduces blood supply. Over time, this causes a sensation of eye swelling and temporary double vision—something eye drops alone cannot fix! So seriously, for the sake of our eyes, please avoid this!
4. Cervical Hyperlordosis
Healthy individuals possess a natural cervical curve. The absence of this curve, or even a curvature in the opposite direction, is termed "hyperlordosis.""Reverse curvature" is the most common pathological basis for cervical spondylosis. Using a high pillow forces the head forward, increasing stress on the lower cervical vertebrae and potentially accelerating degeneration. Poor habits like watching TV with a high-backed pillow, prolonged internet use, or lying down while using a phone constantly strain the cervical spine. This prolonged traction gradually reduces its natural forward curve, straightening it or even causing it to reverse.Impact on Cognitive Function
Mobile phones emit significant radiation, including screen radiation and signal reception radiation. The human body's blood requires a balanced equilibrium of positive and negative electrical charges. Screen radiation can subtly disrupt this balance. While the effect may seem minor, it remains detrimental. Prolonged exposure can weaken the body's immune system, leading to fatigue, nausea, and other adverse reactions. Extended phone use also harms vision.It's advisable to minimize phone use before bedtime. Additionally, radiation from signal reception can affect the brain's nervous system, potentially leading to reduced cognitive function over time.
6. Skin Damage
The radiation emitted by phones should not be underestimated. Since phones are held close to the face during use, they can affect the skin. While it's uncertain whether they cause dark spots, they are definitely detrimental to skin health and can increase acne susceptibility.
7. Finger Numbness
Frequent keystrokes cause thumb soreness. Excessive phone use and constant texting can lead to discomfort like thumb pain, numbness, or swelling.
8. Allergies
Mobile phones can trigger allergies. Some individuals experience unexplained skin allergies shortly after using their phones. Investigations often reveal that certain metals like nickel on the phone are the culprits.
The above briefly outlines the health risks of using mobile phones before bedtime. We hope this information is helpful to you. Wishing you a pleasant life.
