Lesson 1352: The Effects of Electronic Devices and Blue Light
Duration:75 minutes
Topic Introduction:
As modern life binds us tightly to our phones, tablets, computers, and television screens, blue light becomes an invisible factor robbing us of sleep quality. Blue light is more than just "bright"; it directly inhibits melatonin secretion, tricking the brain into thinking it's still daytime, leading to delayed sleep onset, decreased sleepiness, increased nighttime awakenings, and even impaired mood regulation the next day. This course will explain why blue light affects circadian rhythms, why some people are so sensitive to screens that "just looking at their phone wakes them up," and why scrolling through videos late at night puts the brain in a state of heightened excitement rather than relaxation. You will learn how to break the "mind-screen dependency cycle" before bed, how to use gradually dimming light to reset your body's nighttime patterns, and how to establish a truly sleep-supportive "digital shutdown ritual" through herbal teas, Ayurvedic spice soups, Gothic calligraphy practice, and mandala visualization. The goal is not to ban electronic devices, but to teach you to regain control of your circadian rhythm at night, ensuring that blue light is no longer a source of sleep problems.

▲ AI Interaction: Your "Blue Light Sensitivity Index" Test
Many people are unaware that they have "high blue light sensitivity." Write down your situation, and we'll analyze it together:
- ① Do you feel noticeably more awake after looking at your phone for 10 minutes?
- ② Do you often find yourself scrolling through your phone before bed and unable to stop?
- ③ Do you feel compelled to check your electronic devices when you wake up in the middle of the night?
- ④ Is the screen brightness always too bright?
Submit your findings to AI to work together to find the best strategy for the “digital boundaries at night.”
○ Music Therapy - Nighttime Lowered-Frequency Sounds
Even after turning off electronic devices, the brain may still be in a state of over-excitation. Using low-frequency, slow-paced music can help quickly switch to "pre-sleep descent mode."
- Turn the music volume to "background presence but not noticeable".
- Let your breathing follow the music and descend, mimicking the nighttime rhythm.
- It is recommended to play the video immediately after turning off the screen to give the brain a sense of ritual that the content has ended.
○ Herbal Tea Healing Drinks: Chamomile Herbal Tranquil Tea
Recommended reasons:Chamomile can reduce the excitability of the sympathetic nervous system, and the scent of vanilla helps the brain recognize that it's time to get ready for sleep. It's perfect for pairing with a digital shutdown ritual.
usage:Make tea 40 minutes before bed and turn away from all screens, activating "night mode" by drinking tea.
○ Ayurvedic Spice Soup - Screen-off Soup
Make a small bowl of warm soup by simmering turmeric, nutmeg, a little pepper, and warm milk or coconut milk.
Warmth naturally lowers cortisol, allowing the body to return from "screen stimulation" to "internal stability".
Suitable for people who want to improve their ability to keep their thoughts active at night.

Psychological Mandala (Viewing)
Psychological Healing: Psychological Mandala - 98 Thoughts
When you watch a screen, your brain is constantly being attracted, stimulated, and drawn in.
A mandala is not about drawing something, but about observing it.
The process of watching shifts attention from external stimuli to internal stability.
Turn your eyes away from blue light and towards soft textures, and switch your brain from an excited mode to a nighttime rhythm.
Staring at the center of a mandala for 60 seconds can significantly reduce "screen hyperactivity".
○ Medieval Gothic Calligraphy Exercise: Write Your "Nighttime Numerical Boundary Sentences"“
The solid structure of Gothic form helps the brain detach from chaotic content and establish clear boundaries for nighttime.
- I allow myself to rest away from screens.
- The night belongs to my body, not the screen.
- Every stroke tells the brain: Now is the time to be at peace.
Lesson 1352: The Influence of Electronic Devices and Blue Light: Guiding Suggestions for Art Therapy
This page shows you directly:Blu-ray and information flowHow to pull your brain back from "night mode" to "daytime battle mode"? Through visual aids, you no longer just vaguely feel "it seems to have an effect," but see how many signals surround you and think about which channels you can shut down.
I. "The Sea of Screens and the Island of the Brain"“
- Draw a "" in the lower half of the picture“Screen Sea”The symbol is composed of many rectangles of different sizes, representing mobile phones, computers, tablets, etc.
- Write the following information on each screen: message notifications, social media, news, short videos, games, emails, and other content types you frequently view.
- Draw a small one in the upper half of the picture.Brain IslandsThe light color indicates that it originally intended to gradually transition into night mode.
- Use thin lines to project from the screen towards the brain island, symbolizing blue light and information stimulation; then use another color to draw a "protective circle" around the brain: turn off notifications, lock the screen at set times, and keep the phone away from the bedside.
2. "Night Signal Switch Panel"“
- Draw a "like a power control console"“Night signal switch panel”The screen has multiple switches: social media, work groups, news, video platforms, games, and email.
- Write your desired "off time" next to each switch (e.g., 22:00, 21:30) to indicate that you can actively set the nighttime boundary.
- Draw a large main switch at the very bottom of the panel and write: "After 22:30: Enter Night Mode". This symbolizes the switch from multi-channel stimulation to a fasciculation state.
- Once this drawing is complete, you can stick it on your desk or bedside as a daily reminder to "turn off the lights for sleep."

○ 1352. The Impact of Electronic Devices and Blue Light: Log-Based Guidance Suggestions
① Write down which devices you looked at before going to bed today and for how long.
② Record the specific moments when blue light made you more alert.
③ Complete the sentence: "The first electronic device I'm willing to give up for the sake of sleep is..."“
④ Make a promise to your body: "I will give you a night without blue light."“
Please log in to use.
The night should be gentle, but blue light is just daylight being misused. You are gradually returning the night to your body.
