Imagine that it's late at night and everything in your home is immersed in tranquility. Aunt Li, a retired teacher full of life wisdom, lies in bed with her glowing smartphone in her hand. Her eyes are glued to the screen, scrolling through the news of her circle of friends, looking at photos of her family, and occasionally clicking on a health tip or a piece of news. Time passed quietly, and when she finally put down her phone, she found that it was late at night, and her mind was still echoing with all kinds of images on the phone screen. Tossing and turning, drowsiness – it's a common phenomenon we can all encounter.
In this era of ubiquitous smartphones, they have become an integral part of our lives. However, did you know that using your smartphone before bed can not only affect our sleep quality, but it can also have long-term effects on our overall health? As a sleep expert, I'm here to share with you some in-depth insights and practical guides to help you protect and improve your sleep quality while enjoying the convenience of smart technology.
Phone screen: The "invisible" destroyer of your sleep quality
The negative impact of using smartphones at night on sleep has become a common phenomenon in modern society. Let's dive into the question and explore the science behind it.
The blue light emitted by smartphone screens has a direct impact on our sleep cycle. This light inhibits the secretion of melatonin, a key hormone that regulates the sleep-wake cycle. Exposure to too much blue light at night can make our brains mistakenly think it's still daytime, which can delay sleep time and make it difficult to fall asleep.
Using your phone before bed is not only a visual stimulus, but can also be a psychological and emotional stimulus. Activities such as browsing social media, reading the news, or playing games tend to keep our brains highly active, and these mental activities can lead to mood swings, increase feelings of anxiety, and further affect sleep quality.
Staring at a screen for long periods of time can also cause eye strain and physical discomfort. Especially for middle-aged and elderly people, prolonged visual focus can increase eye pressure and may even cause headaches, and these physical discomforts can also affect sleep.
We should also be aware that the Xi of using our phones before bed may subtly change our biological clock and sleep patterns. Over time, this alteration can lead to chronic sleep disorders that affect our overall health and quality of life.
Smartphones: Night Watchman or Sleep Disruptor?
Smartphones have become a part of our daily lives, but they may be more than just transmitters of information at night. The use of smartphones before bed has a significant impact on sleep quality, and this phenomenon deserves further discussion.
From a physiological point of view, the blue light emitted by smartphone screens inhibits the secretion of melatonin. Melatonin is a key sleep-regulating hormone that helps regulate our biological clock. When exposed to too much blue light at night, the body may mistake it for daytime, delaying sleep and making it difficult to fall asleep.
The content on the smartphone itself is also a factor that cannot be ignored. Whether it's the feed of social media, or engaging news and games, it stimulates the brain on a psychological level and keeps it highly active. In this state, even if you put down your phone, it takes a long time for your brain to "cool down" before it can enter a resting state.
Using smartphones at night can also lead to confusion in sleep cycles. The human body's sleep cycle consists of multiple phases, and frequent checking of mobile phones at night may cause the sleep cycle to be interrupted, affecting the depth and quality of sleep. In the long term, disturbances in this sleep pattern may even lead to sleep disturbances.
In order to ensure the quality of sleep and reduce the negative impact of smartphones on sleep, there are a few things we can do. For example, avoid using your phone for a certain amount of time before bed, or use night mode to reduce the effects of blue light. Also, choose relaxing activities to replace your evening phone time, such as reading a paper book, taking deep breathing exercises Xi or light body stretching, which can help promote better sleep.
A guide to smartphone use to improve sleep
In this information age, smartphones have become an indispensable part of our lives. However, using them at night can often have a negative impact on the quality of our sleep. To help you sleep better, here are some practical tips:
Set "Night Mode" to reduce blue light
Most smartphones are equipped with "Night Mode", a feature that reduces the blue light emitted by the screen. Blue light has been shown to interfere with our biological clock, which in turn affects sleep cycles. Activating this mode before using your phone can help reduce the impact on sleep.
Limit the use time at night
It is recommended to stop using your smartphone at least an hour before bedtime. This time can be used for relaxing activities such as reading paper books or doing a relaxing yoga Xi.
Use Do Not Disturb to reduce interruptions
Turning on your phone's Do Not Disturb mode at night can prevent notifications and calls from disturbing your sleep. You can set to allow only incoming calls from emergency contacts to pass through to ensure a calm night.
Avoid using your phone in bed
Keep your bed as a space for sleep and rest. Not using your phone in bed can help your brain associate your bed with sleep, which can improve sleep quality.
Choose healthy alternative activities
Engaging in healthy activities before bed, such as light reading, meditation, or listening to soft music, can help you fall asleep faster.
By implementing these simple yet effective strategies, you can significantly improve the quality of sleep that is impaired by using your smartphone at night. Remember, good sleep Xi is essential for maintaining health and vitality.
