What Are the Hazards of Frequently Staying Up Late to Use a Smartphone?

The hazards of regularly staying up late to play mobile phones mainly include eye damage, sleep disturbance, intellectual impairment, social impact, and endocrine disruption. Here are the details:

1. Eye Damage: When lying on the bed and playing mobile phones on one side, it can cause significant pressure on both eyes, compressing the blood vessels and leading to insufficient blood supply. This can quickly result in vision deviation between the left and right eyes. Viewing the mobile phone screen in a dark environment can strongly stimulate the eyes due to the bright light, causing eye fatigue. Within a month, this can lead to myopia or even astigmatism. Especially for children under 3 years old, it is recommended to limit their exposure to bright lights to 15 minutes or less to prevent vision damage.

2. Sleep Disturbance: Adequate sleep is a necessary safeguard for a healthy life. When using mobile phones, the production of melatonin (secreted by the pituitary gland, which directly affects sleep quality) decreases, leading to lighter sleep or even insomnia. To improve this, reduce the screen brightness and maintain a distance of at least 14 inches (about 35 centimeters) from your face. Avoid bringing your phone to bed when sleeping.

3. Intellectual Impairment: The human body requires a balance of positive and negative charges in blood circulation. Mobile phones constantly emit electromagnetic radiation, which can disrupt this balance. Long-term exposure can lead to decreased immunity, fatigue, and a sub-healthy state. Since the balance of positive and negative charges is closely related to neural transmission, damage to brain neural transmission can result in intellectual decline.

4. Social Impact: Over-reliance on mobile phones and other technological devices can lead to increased neglect of people in one's immediate surroundings. People who are active online tend to feel more lonely in real life. To mitigate this, reduce mobile phone usage during dinner and engage in more conversations with family members. When socializing outdoors, also avoid excessive use of mobile phones to avoid neglecting others.

5. Endocrine Disruption: Studies have found that using mobile phones, tablets, and other electronic devices for two hours before bedtime can suppress melatonin secretion, leading to insomnia. Over time, this can cause endocrine disruption. Deep into the night is the time for sleep, and the various systems of the body should be resting. If the body is still active and the circulatory system is still operating during this time, it can lead to abnormal hormone secretion and endocrine disruption. Symptoms may include acne on the face, and in severe cases, metabolic diseases such as diabetes can develop.
