The turbo thought this morning; no matter how rich you are or how powerful you are, or how much you will it, you cannot control the sun.

No man or person or even god can suddenly will the clouds to part, and the sun to come out.

The difference between the real sun and artificial UV sun.

Certainly better to have a fake sun than just be in the underground bunker.

Also, certainly there are hidden benefits of the real sun that even modern day science has yet discovered.

Upsides of sunlight

1. Improves your mood, also regulating your circadian rhythm. Or another words, spending more time in the sun during the day helps you sleep better at night?
2. Real tan — beautiful.

The difference between the real sun and artificial UV sun.

The difference between the real Sun and artificial UV (ultraviolet) sources, such as UV lamps, encompasses a range of factors including the spectrum of UV radiation emitted, their applications, and the health effects associated with exposure to these sources. Here’s a pragmatic and useful comparison:

1. Spectrum of UV Radiation

• Real Sun: The Sun emits a broad spectrum of electromagnetic radiation, including visible light, infrared (IR), and ultraviolet (UV) radiation. UV radiation from the Sun is categorized into three types based on wavelength: UVA (315-400 nm), UVB (280-315 nm), and UVC (100-280 nm). The Earth’s atmosphere absorbs all UVC and most UVB radiation, so the majority of UV radiation reaching the Earth’s surface is UVA, with a small amount of UVB.
• Artificial UV Sun: Artificial UV sources can be designed to emit specific types of UV radiation, often focusing on UVA or UVB, and in some specialized applications, UVC. These sources can provide a more controlled exposure to UV radiation, which can be beneficial for various applications but lacks the full spectrum of sunlight.

2. Applications

• Real Sun: Exposure to sunlight has several benefits, including the production of vitamin D in the skin, which is crucial for bone health and immune function. Sunlight also regulates circadian rhythms and can improve mood.
• Artificial UV Sun: Artificial UV sources are used in various applications, including medical treatments (e.g., for psoriasis, vitiligo, and seasonal affective disorder), tanning, sterilization and disinfection, and in scientific research. These sources allow for controlled exposure times and intensities, which can be tailored to specific needs.

3. Health Effects

• Real Sun: While moderate exposure to sunlight has health benefits, excessive exposure can lead to skin aging, DNA damage, and increased risk of skin cancer. The risks are associated with both UVA and UVB radiation.
• Artificial UV Sun: The health risks of artificial UV sources depend on the type and intensity of UV radiation, as well as the duration of exposure. Like natural sunlight, excessive exposure to artificial UV radiation can increase the risk of skin aging and cancer. It’s important to use these sources according to safety guidelines and recommendations.

4. Environmental Impact

• Real Sun: The Sun’s energy is a clean and renewable resource, with no direct environmental impact from its use for light or warmth.
• Artificial UV Sun: Artificial UV sources require electricity to operate, which may contribute to environmental impact depending on the source of the electricity. Additionally, the manufacturing and disposal of UV lamps can have environmental effects.

In summary, while both natural and artificial UV sources have their unique benefits and applications, they also come with specific considerations regarding health and safety. The use of artificial UV sources can offer controlled and specific applications not possible with natural sunlight, but it is essential to understand and mitigate the potential health risks associated with UV exposure.
