What are the harms of using mobile phones before bedtime?

The harms of using a mobile phone before bedtime typically include effects on the skin, fingers, vision, cervical spine, and sleep onset.

1. Skin problems

When using a mobile phone before sleeping, the device is held close to the face, exposing the skin to certain radiation that may lead to pigmentation or acne, negatively affecting skin health.

2. Finger problems

Using a mobile phone before bed, especially with frequent button pressing, can cause soreness in the thumbs. It may also lead to numbness, swelling, and other discomforts in the thumb.

3. Vision problems

Using a mobile phone in the dark before sleep exposes the eyes to blue light from the screen, which can damage the eyes, significantly reduce visual acuity, and even cause symptoms such as dryness, blurred vision, and eye pain.

4. Cervical spine problems

Using a mobile phone before bedtime often involves maintaining the same posture for extended periods. Prolonged use can impair blood circulation in the neck area and affect cervical spine curvature, leading to a gradual reduction or straightening of the natural forward curve, and even reversed curvature.

5. Sleep disruption

Using a mobile phone before bed usually suppresses the production of melatonin, making it difficult to enter deep sleep and reducing overall sleep quality.

To promote better health, avoid prolonged mobile phone use before bedtime and maintain a good sleep environment. If discomfort occurs, it is advisable to visit a hospital for evaluation and appropriate treatment based on medical findings.
