2. Effects and data of long-term absence of sunlight
| Impact Category | Specific performance | scientific data |
|---|---|---|
| human health | Vitamin D deficiency, seasonal depression | When sunlight is reduced by 50%, depression rates rise by 37% |
| agricultural production | Extended crop growth cycle | Insufficient light leads to a 20-45% yield reduction |
| energy consumption | Lighting/heating demand surges | Electricity consumption in Nordic countries increases by 300% in winter |
3. Practical solutions
1. Personal responses
• Use a light fixture above 10,000lux for 30 minutes a day
• Supplement vitamin D3 (400-800IU daily)
• Choose full spectrum LED lighting fixtures
2. Family emergency preparedness
| thing | Function | Recommended brands |
|---|---|---|
| solar charging panel | Store residual light energy | Anker/GoalZero |

3. Community-level solutions
• Establish underground vertical farms (the latest Tokyo case shows an 8-fold increase in production capacity)
• Install light therapy rest stations in public spaces (already piloted in Sweden)
• Develop low-light resistant crops (new breakthrough in CRISPR technology)
4. Trends at the forefront of science and technology
China's Hefei "Artificial Sun" EAST device recently achieved 403 seconds of steady-state operation and may provide clean energy alternatives in the future. Private aerospace company SpaceX has proposed an orbital mirror plan to increase surface illumination through a group of space mirrors.
Conclusion:Despite the challenges of long periods without sunlight, humans have gained experience through technological innovation and adaptation. It is recommended that the public pay attention to authoritative weather forecasts, reserve supplies scientifically, and maintain confidence in scientific and technological development.
