Properties of Sun Light

 

The sun is a really hot ball of gas, with an internal temperature that goes over 20 million degrees Kelvin.

Nuclear fusion at the sun's core changes hydrogen into helium. Scientists think the sun is about 4.6 billion years old. The energy we get from the sun affects the environment on Earth, which is super important for human life.

PROPERTIES

Sunlight is a type of electromagnetic radiation emitted by the sun, including infrared, visible, and ultraviolet rays.

The ultraviolet rays in sunlight can have both good and bad effects on health. There are different types of radiation, including:

ULTRAVIOLET-C: This type is not visible to the human eye, and only a tiny bit of it makes it to the atmosphere.

Even though we’ve known for a century that UVC radiation can kill germs, using it to prevent and treat infections is still just starting to be developed.

➢ UV-B: This type of UV radiation is mostly absorbed by the atmosphere and, along with UV-C, plays a key role in the photochemical reactions that lead to the formation of the ozone layer. It can directly harm DNA and is a cause of sunburn. However, it is also necessary for the production of vitamin D.

➢ UV-A: This type is considered to be less harmful to DNA compared to UV-B, which is why it is often used in artificial tanning treatments. It can still indirectly damage DNA and has the potential to lead to skin cancer.

➢ INFRARED RAYS: These rays are a significant part of the electromagnetic radiation that reaches the Earth. They are categorized into infrared A, B, and C.

➢ VISIBLE RANGE/ LIGHT: As the name implies, this is the range of light that can be seen with the naked eye, and it is known to be the sun's strongest output.

THERAPEUTIC PROPERTIES

➢ Analgesic property/ pain killing property: Patients who were exposed to higher levels of sunlight reported feeling less stress and experiencing reduced pain.

➢ Sunlight helps burn fat: Unlike visceral fat, subcutaneous fat isn't seen as a risk for heart disease. When our skin is exposed to UV rays, it boosts the metabolism of subcutaneous fat. This process plays a role in regulating how long we live. It's said that solar cycles can directly influence our lifespan and even impact our genetic makeup. Getting sunlight might actually affect how long we live and could speed up genetic changes.

➢ Enhances alertness in the evening: Light exposure in the early evening can improve our performance, reduce feelings of sleepiness, and affect our hormones in a positive way.

➢ Sunlight might be turned into metabolic energy: There's a long-held belief that animals can't use light energy directly, but this has been challenged. In other words, our skin might have something similar to melanin, allowing us to absorb energy from sunlight just like plants do.

➢ Advantages of sunbathing: it enhances blood flow.

It aids in detoxifying the body. It assists in the production of vitamin D when ergosterol, which is present in the skin, is available. It benefits conditions like osteoporosis, paralysis, gout, tuberculosis, and various skin issues.

CONCLUSION

The sun emits heat and light as universal energy, while the inner fire helps eliminate waste and promotes circulation within the human body. Therefore, the sun is the primary source of energy and life.
