Know the Sun and its Benefits for the Earth

Knowing the Sun and Its Benefits for the Earth . The sun plays a very important role in the solar system , including the sun as the center of circulation and a source of energy in the solar system environment. The sun is a large, luminous ball of gas. The sun’s diameter is roughly 1,400,000 kilometers, which is more than 100 times the diameter of the earth. The mass of the sun is equal to 333,420 times the mass of the earth.

The sun’s gravity is 28 times that of the earth. This means that someone who weighs 90 kilograms on the surface of the earth, if on the surface of the sun, will weigh 28 × 90 kilograms or equal to 2,520 kilograms or 2 1/2 metric tons.

At the center of the sun, the temperature reaches 14,000,000 ° C or higher, but the temperature at the sun’s surface is much lower, between 5,000 ° C and 6,000 ° C. These temperatures are still high enough to evaporate almost all solid and liquid substances on earth. .

The body composition or structure of the sun is spread out as follows.

  1. Core

The core or interior of the sun is the largest part of the sun. This is where the thermonuclear reaction takes place. The temperature reaches 20 million degrees Kelvin.

  1. Photosphere

The surface (skin) of the sun is called the photosphere. This is where we can see sunlight coming to earth. The temperature of this layer is 6,000 ° Kelvin. The surface of the photosphere is not a flat surface, but rather shaped like spots (granules), which is called photosphere granulation. On the surface of the photosphere, there are black spots called sunspots. The appearance of these spots can cause electrical disturbances in the earth’s atmosphere, which can result in radio broadcasts and electromagnetic needle interference.

  1. Sun atmosphere

Above the photosphere there is an atmosphere from the sun which consists of three parts, namely the inversion layer, the chromosphere, and the corona.

  • The inversion layer is a layer of cold incandescent gas composed of various metals. When a solar eclipse occurs, the spectrum of the gas envelope is clearly visible.
  • The chromosphere is a very hot and very brittle gas layer that surrounds the sun. When a solar eclipse occurs, this layer looks like a reddish ring around the sun, and the darker part is because it covers the moon.
  • The corona is a small layer of gas that surrounds the sun around the chromosphere layer, which is shiny white. The temperature reaches 1,000,000 ° Kelvin. During the corona, only the sun’s corona is visible.
  1. Sun stain

At temperatures as high as 4,000 ° C, sunspots appear darker, cooler and less radiant than the rest of the photosphere. The darker part of the sunspot is called the umbra, and the lighter part is called the penumbra.

  1. Sun movement

The sun rotates from west to east at varying speeds. Some parts rotate faster than others. There are two movements in one solar revolution, as shown below.

  1. The time for one revolution around the axis is 26.9 days (on Earth).
  2. Moving between constellations at a speed of 20 km / s. This movement causes a knot in the sky called the Apex. The rotation of the sun around its axis is the same as the rotation of the earth and the moon around its respective axis, as well as the rotation of the earth around the sun and the moon around the sun.
  1. Sun element

Hydrogen is the main element of the sun, with a mass exceeding 80%. Helium is the second element at 19%. The remainder of the solar period consists of the very important elements.

The sun is a mixture of gas atoms, aatomic center and atomic particles such as electroons, prootons (charge +), neutroons, positroons (charge +) and neutrinos. Plasma is a mass formation from the sun. At high temperatures, chemical reactions are almost impossible under the sun.

  1. The impact of solar energy on earth

The sun is the absolute source on this earth. Sunlight that reaches the earth only contributes half of the total solar energy because of the distance from the sun is far from the earth. The impact of solar energy on human life on earth is as follows.

A. Influence of infrared

As one of the sun’s invisible spectrums, infrared light actually has the greatest potential and thermal effect. Its impact on life lies in its role in the formation of the water cycle on earth (infrared rays evaporate sea water, then sea water will condense and fall with the rain).

B. Effects of ultraviolet light

As one of the sun’s invisible spectrums, ultraviolet rays actually have the greatest potential and chemical effects. Its effects on life include:

  • Has the ability to kill bacteria, especially skin diseases;
  • Provide energy to plants for the assimilation process;
  • As a source of vitamin D, its function contributes to the growth and health of human bones.
  • The energy emitted by the sun can be directly converted into electrical energy that can be used in human life.
  • The energy emitted by the sun can be converted directly into heat energy. Heat energy can be used to heat hot water, which is useful for hot showers.

The benefits of the sun for our bodies

  1. Source of Vitamin D

The benefits of sunbathing in the morning can get as much free vitamin D as possible. Once the ultraviolet light is filtered on the skin, it converts the cholesterol stored in the skin into vitamin D. Just five minutes of sun exposure is the equivalent of giving your body 400 vitamin D. Interesting?

  1. Builds and strengthens bones

The benefits of morning sunshine for humans can nourish bones. Sun exposure will increase the content of vitamin D in the body and help the absorption of calcium in the body. Sunlight is a solution for bone formation, repair and prevention of diseases, such as childhood diseases and bone loss such as osteoporosis and osteomalacia.

  1. Reducing the risk of diabetes

According to experts, vitamin D can prevent diabetes. A 2006 study conducted by Lund University and Malmö University Hospital in Sweden found that getting vitamin D early in life was associated with a reduced risk of type 1 diabetes.

  1. Prevent cancer

Although prolonged sun exposure increases the risk of skin cancer, moderate morning sunshine can actually prevent many types of cancer, including colon cancer, Hodgkin’s lymphoma, ovarian cancer, pancreatic cancer, and prostate cancer. According to researchers reported by Healthline, people who live in areas with fewer hours of the day are more likely to develop some types of cancer than areas with more sunlight during the day.

  1. Overcoming skin diseases

According to the World Health Organization (WHO), sun exposure can help treat certain skin diseases. Doctors recommend that you stay in the morning sun to adapt to a variety of skin conditions, including psoriasis, eczema, jaundice, and acne. Although not everyone can receive sun therapy, a dermatologist can suggest treatments for mild skin conditions to help speed healing.

  1. Deal with depression

The benefits of morning sunshine can help reduce depression. People who are not exposed to sunlight are at risk for some form of depression, called seasonal affective disorder (SAD), or seasonal affective disorder. This situation mainly occurs during the rainy season. A study conducted by the University of Milan in Italy in 2001 showed that the benefits of morning sunshine can reduce the length of stay in bipolar patients. When there is no sunlight in the hospital room, the length of stay for patients in the hospital will increase compared to the room receiving sunlight.

  1. Reducing the risk of high blood pressure

A 2008 study by Harvard Medical School found that due to a lack of sunlight, the risk of hypertension increases. In addition, according to the same study, sunlight can directly affect the risk of cardiovascular disease. Vitamin D appears to be one of the most powerful hormones for regulating blood pressure.

  1. Reducing the risk of multiple sclerosis

According to a study conducted by the Australian National University, people living in latitudes with little sun exposure have a higher risk of developing multiple sclerosis. This means that sunlight can reduce the risk of multiple sclerosis. Latitudes with little sunlight include North America, Europe and Iceland.

  1. Helps overcome psoriasis

Psoriasis is a skin disease characterized by a red, dry, scaly rash. Easy to peel. It is said that this skin disease is difficult to cure. However, phototherapy can be used to treat psoriasis, which is also known as phototherapy. Sunlight is a source of light that can help reduce psoriasis.

  1. Reduce cortisol levels

The stress hormone is called cortisol. This hormone increases appetite, and experts say that high cortisol levels can lead to weight gain. According to research conducted by the University of Colorado Neuroscience Center, it was found that morning sunlight can lower cortisol levels.

  1. lose weight

Are you running a weight loss program? If so, please consider adding a vitamin D supplement to your diet, as it can help you lose weight. If you don’t want to take vitamin D supplements, just stay in the morning sun for free vitamin D! You need to know that the benefits of morning sunlight can also help you lose weight. Sunbathing in the morning helps get rid of excess body fat.

  1. Overcoming hair loss

The benefits of sunbathing in the morning can also treat hair loss. However, it is important to note that prolonged sunlight can actually damage hair. Therefore, be careful in the sun, or not too long. Why is that? Because the epithelial cells that are known to aid hair growth are very sensitive to ultraviolet light, overexposure reduces the levels of vitamins E and C which are essential for hair growth.

  1. Improve brain function

Apart from improving bone health and regulating calcium levels, vitamin D is also associated with many body functions, including brain function. A study led by neurologist David Llewellyn of the University of Cambridge assessed the vitamin D levels of more than 1,700 men and women aged 65 and older and found that when these subjects had low vitamin D levels, cognitive function was affected. Several other studies have found that sunlight can help stimulate brain growth in the hippocampus, a very powerful component. In conclusion, vitamin D levels caused by sunlight can improve human brain function.

  1. Improve sleep quality

Trouble sleeping or insomnia? Try sunbathing in the morning, because the benefits of sunlight can make you sleep soundly. This is because when direct sunlight hits the eye, it sends a message to the pineal gland in the brain, and the production of melatonin (the sleepy hormone) stops until the sun sets again. Sunlight sends a clear signal to the body that it’s not night anymore, which helps to maintain a normal circadian rhythm. When it’s dark outside, your body receives a signal, so you feel tired and sleepy before bed.

  1. Strengthens the immune system

The benefits of sunlight can help suppress an overactive immune system, which is why sunlight can be used to cure autoimmune diseases such as psoriasis. White blood cells increase with exposure to sunlight, which plays an important role in fighting disease and protecting the body from infection. Adequate sun exposure helps your immune system.

Benefits of the sun for animals

  1. Sources of Energy for Plants that Benefit Animals

FlorA really needs solar to do photoosynthesis. Which means that all fauna can also enjoy the benefits of eating plants and feel the benefits of sunlight through plant intermediaries.

There is also sugar that plays a role in saving power in order to grow, another way can also make oxygen like a residual element. Like humans, some animals also need oxygen to breathe.

  1. Warm your body

According to the National Wildlife Federation, cold-blooded animals such as reptiles, amphibians and fish depend on the temperature of their environment. When the sun is shining, their bodies absorb heat.

This keeps the body warm and makes it more active. When the weather is cold, these animals are easily sleepy because their body functions automatically slow down to save energy.

  1. Helps digest food

To digest food quickly, certain animals use the sun’s heat. An example is a snake.

After eating, the snake needs to raise its body temperature to digest the food. Therefore, snakes usually bask in the sun.

Benefits of the sun for plants

  1. Make the soil dry

The first benefit of solar energy for plants is to dry the soil so that plants can survive. In certain types of plants (such as sunflowers), energy from sunlight is very useful in the reproduction process.

In this case the sun’s energy is needed to dry the soil, during this drying process the sunflower seeds that fall to the ground will thrive.

However, if the soil conditions are wet or humid, sunflower seeds that fall to the ground will not grow. Sunflower seeds will still be able to grow in moist soil surfaces, but will quickly wither and die.

  1. Make warm seeds

The advantage of solar energy for the next crop is that it can heat seeds, such as other types of sunflowers. Most plants, including sunflowers, adapt to sunlight.

In short, sunflowers and other plants will lean toward the sun. But, do you already know why plants tilt toward the sun?

The short answer is that if plants lean towards the sun, they will get a lot of energy from the sun’s rays.

The movement of plants that tend to reach sunlight is called phototropism. Phototaxis will emerge as a form of adaptation, allowing plants to obtain maximum sunlight energy during photosynthesis.

  1. Maintain plant temperature

The next benefit of solar energy for plants is to maintain plant temperature. The sun will help plants maintain the temperature stability needed to transfer water to maintain stability and balance.

Plants will absorb water from the soil through their roots and then evaporate through the leaves. However, if the temperature inside the plant is too low, the evaporation process will take a long time and cause the plant to die.

Likewise, if the temperature is too high it will speed up the evaporation process and dry out the plant.

  1. Help grow

Of course, all plants will need sunlight to enhance their growth process. However, not all plant species require the same light intensity.

Certain types of plants require little or moderate sunshine, and only a few hours of sunshine a day can make them thrive.

Likewise for certain types of plants that need a lot of sunlight. The plant needs lots of sunlight and can thrive for 8 hours a day on solar energy.

  1. Photosynthesis

In the process of photosynthesis, green leafy plants absorb energy from sunlight through chlorophyll. The benefits of solar energy for plants are that it can help chemical processes to produce glucose (sugar).

This sugar will then be used to form other organic compounds. For example, cellulose is used as a basic material to be converted into protein and fat as vegetable food.

Then, the results of photosynthesis will be circulated to all parts of the plant to breathe, reproduce and grow, and the rest will be stored as food reserves. Then store these foods in roots, tubers, fruits and seeds.

In the process of photosynthesis, plants will produce leftover substances in the form of oxygen (O2) which humans can use to breathe. But what about leaves other than green, such as red, yellow, and brown plants?

Do plants of this type do not undergo photosynthesis? Whether or not a plant can undergo the photosynthesis process does not depend on green leaf pigments. However, all plants depend on their chlorophyll.

All types of plants have chlorophyll, but not all plants are green. Some plants contain chlorophyll, but have red, brown, and yellow leaves.

  1. As the best source of nutrition

The benefits of solar energy for the plant will then be the best source of nutrition. In one experiment, plants were placed in a closed room with artificial lighting. The result of this experiment is that even with artificial light, the plants will continue to grow.

But the energy and nutrients produced are never as good as those produced by sunlight.

  1. Activate Chlorophyll

Sunlight radiation can be used to activate chlorophyll in plants. Therefore, new plants or shoots that don’t get enough sunlight will turn yellowish. This is also included in the important benefits of solar energy for plants.

Vice versa, new shoots or plants that receive direct solar energy will turn green. Sunlight automatically activates chlorophyll.

  1. Maintains green color in plants

Usually chlorophyll absorbs red and blue in the wavelength of sunlight. However, because green is not absorbed by plants, but red and blue are absorbed, green is visible to the naked eye.

In fact, red and blue are the colors used in the photosynthesis process, even if the leaves we see with the naked eye will turn green, you know.

  1. Helps the growth of flowers and leaves

The last benefit of solar energy for plants is that it helps plant flowers and leaves. As I explained to my friends in the above point of view, the wavelengths of sunlight are colored.

Regarding plants, the red wavelength of the sun that will be absorbed by plants affects flower growth. Eventually, these plants will be exposed to the wavelength color of sunlight, making them taller, denser, and blooming faster.

In addition, the blue color at daytime wavelengths will affect leaf growth. In this way, plants exposed to the long wavelength blue rays of the sun will have bushy leaves.

Benefits of the sun for nature

The sun has many benefits for nature, and the benefits of solar energy are not only for humans, animals and plants. As you know, the benefits of the sun for nature include being the center of the Milky Way. All celestial bodies, such as planets, moons, asteroids, comets, etc., revolve around the sun.

This happens because the sun’s gravitational pull is very large. Imagine the many planets that are millions of light kilometers away. Another benefit of the sun for nature is that it acts as an infinite source of natural energy in the form of rays. The rotation of the earth also causes day and night, and the part that is exposed to the sun is the area during the day.

Wow, the sun has many benefits for humans, animals, plants, nature and life.
