7 Radiant Reasons Why Sunlight Is Good For You

The first time it was arguably discovered that sunlight is good for you was in 1890 when Theobald A. Palm figured out that sunlight could prevent and cure rickets, a disease that was affecting children by deforming and weakening their bones. 

Although sunlight is associated with curing rickets, many people are not aware that it was used to cure tuberculosis (TB) on or about the same time with the use of heliotherapy (Sunlight exposure). 

Heliotherapy was one of the first medical treatments for TB, particularly skin TB.

What is Sunlight?

7 Radiant Reasons Why Sunlight Is Good For You

We all learned in school that the sun is made up of different energy sources. Generally speaking, the sunlight that reaches the earth consists of approximately 50% infrared light (IR), 40% visible light, and 10% ultraviolet light (UV).

However, there are other rays the sun emits, such as gamma rays, x-rays, cosmetic rays, and several others.

Sunlight is the ultimate supporter of all life on earth. Without it, everything on this planet would perish within three weeks. Sunlight is good for you and is the most significant source of life on earth.

The food that everyone eats is in one way or another connected to sunlight. Without it, there would be no plants, trees, or vegetation.

There no longer would be any photosynthesis produced, and without photosynthesis, there would be no life on earth except, possibly, for some bacteria found deep in the oceans.

Now that we have an idea of how crucial sunlight is let’s discuss numerous reasons why sunlight is good for you.

7 Radiant Reasons Why Sunlight Is Good For You

1. Sunlight’s Infrared Rays (IR) Are Useful In Treating Diseases

Many people are unaware of the beneficial effects of the Infrared Rays from sunlight.

Various studies have announced that Infrared Rays can help in pain relief, stiffness of the body, arthritis, assist in psychiatric disorders, heal wounds faster, and much more. 

In the last several years Sports Clothing Companies have used Infrared with nanotechnology techniques to create clothing that can enhance athletic performance.

Studies have also shown that Infrared was capable of increasing collagen synthesis in rats.

2. A Great Source For Vitamin D

Sunlight Is Good For You Because Of Vitamin D

An essential benefit of sunlight is its ability to provide the body with a good supply of vitamin D (The sunshine vitamin). Many people are deficient in this vitamin because they avoid sun exposure.

Approximately 1,000 different genes that oversee practically every tissue in your body are presently believed to be controlled by Vitamin D3, an active form of vitamin D, such as muscles and immune system regulation.

Ultraviolet light from sunlight can transform cholesterol found in the skin into Vitamin D.

Vitamin D is vital for the proper administration of calcium in the body, and this makes it is beneficial in the prevention of rickets and osteomalacia.

Osteomalacia is a disease that softens the bones caused by low amounts of available phosphorus and calcium.

Vitamin D is vital for maintaining your bones, brain, heart, and pancreas in a healthy condition. It also plays a role in preventing medical problems such as anxiety, heart disease, and bone diseases.

All you need is about 10 to 20 minutes per day of sunlight to hit your skin to get the daily requirement of vitamin D.

3. It’s Ultraviolet (UV) Rays Are Disinfectant

The ultraviolet rays are a potent disinfectant with the ability to kill bacteria, viruses, fungi,  and more. 

Studies as far back as the late 1800s knew that the UV rays from sunlight were capable of killing potentially deadly bacteria. 

The UV rays from sunlight are an incredible way of disinfecting your home or office. Simply pull up all your curtains and let as much sunlight as possible to penetrate your home. 

The UV rays will kill bacteria that can make you sick that has attached itself to dust particles floating throughout your home. 

UV rays have also been used to disinfect drinking water.

4. Is Essential For Healthy Skin

Contrary to popular belief, sunlight is actually good for the skin. Sunlight is essential for healthy skin, making it less susceptible to infection or disease. The objective is to get sensible and moderate exposure to sunlight. Only prolonged exposure can cause damage to your skin.

Instead, the proper exposure protects it by developing a natural resistance to the potential adverse effects of ultra-violet light, while supplying it with a soft, smooth texture.

Another benefit of UV rays from sunlight is sun-bathing with controlled moderation. It has been proven that it can help heal medical skin conditions such as dermatitis, acne, rosacea, and eczema.

5. Sunlight May Enhance Longevity

7 Radiant Reasons Why Sunlight Is Good For You

Another incredible reason why sunlight is good for you is that it can possibly help you live longer. A medical study published in 2007 states that sunlight, particularly UV light, may be a regulator of human lifespan. According to the researchers of the study:

Lifespan variation appears to be modulated by seasonal light confirming that genome and environment are closely linked very early after conception. Although the precise pathogenesis is still unknown, the phenomenon must involve radiant energy, probably ultraviolet light, possibly affecting the maternal immune system through the dermis.”

Therefore, if we adhere to what this study has claimed,

This study also supports the reliability theory of aging which suggests that events affecting the genome…are important in the expression of adult diseases.”

and you expose yourself to the appropriate amount of sunlight, you may be able to somehow prolong your lifespan by avoiding any possible predisposing diseases you may encounter later in life.

6. May Regulate Your Hormones 

We will start with the pineal gland, which is a small, round-shaped gland located in the middle of the brain.

The primary purpose of the pineal gland is to make melatonin and serotonin. They are two important neurotransmitters that play a significant part in controlling how your brain and endocrine system function.

Another purpose for the pineal gland is to let your body know information about the environment you’re in, such as what season it is or what part of the day it is.

However, for the pineal gland to properly perform its job, it needs both sunlight and darkness. It is also connected with the hypothalamus gland.

The hypothalamus regulates many vital parts of your body, including but not limited to your breathing, blood circulation, nervous system, body heat regulation, and more.

In other words, the pineal gland is like the chief engineer, and the hypothalamus is the schematics station. Both the pineal and hypothalamus are influenced by the amount of sunlight that gets to them through the eyes. An article in the N.Y. Times stated the following:

Light exerts its internal biochemical effects through the eye. Light passes through the retina to the optic nerve. Part of the optic nerve goes to the brain’s vision center and the other part goes to a section of the hypothalamus, the suprachiasmatic nucleus, which is the body’s internal clock. From this nucleus, the light-generated nerve message travels through the brain to the spinal cord and out a nerve center, called the superior cervical ganglion, that transmits it to the pineal gland.”

If not enough sunlight reaches the pineal gland, it will not be able to make enough melatonin because it will become calcified. This can cause people to get brain tumors.

7. Sunlight Can Make you Fitter

Sunlight Is Good For You Because It Makes You Fitter

Another great reason why sunlight is good for you is that it can make your body feel like you just did an incredible exercise routine. It can improve agility, power, and muscle size. Studies have shown that vitamin D from sunlight enhances athletic performance, and can help you lose weight.

Strengthens Your Muscles

There’s more to being fit than exercise and looking good. The strength of your muscles plays a significant role in your fitness plan.

Your muscles and bones both need vitamin D to be at their peak. Sunlight has been shown to raise the oxygen level in your blood, and because of this, it will boost the blood supply that will travel to the muscles.

Also, as mentioned earlier in the article, sunlight is an excellent source of vitamin D. A deficiency in this vitamin can cause sarcopenia, known as loss of muscle tissue.

Helps You Lose Weight

Sunlight is good for you because it can also help you lose that jiggly fat that is hard to get rid of and can help you get ripped.

Sunlight can also help you speed up your metabolism by letting it stimulate your thyroid gland. It has been shown that people that are overweight are deficient in vitamin D.

Another benefit of sunlight is that it triggers the production of Melanocyte Stimulating Hormone (MSH), which has been shown to help you lose weight and give you more energy.

It Provides Better Results In Your Exercise Routines

Studies show that when you work out in the sun, you get more out of your workouts.

  • A study showed that the UVA rays of sunlight exposure could increase endurance by enhancing nitric oxide. This process helps in the widening of blood vessels, which brings more oxygen to the muscles. The more oxygen you have, the faster and longer you will be able to run.


The sun can be dangerous if you are overexposed to it. But as shown in this article, there are plenty of reasons why sunlight is good for you. 

Moderate sunlight is good for you. The rule is moderation. 

Completely avoiding the sun is not a good idea and can lead to serious medical problems. 

Too much sunlight can also cause medical problems, particularly skin cancer.  

Be smart, and sun-bathe or work out in the sun in moderation. Try to get those sun-rays before 10:00 am or after 2:00 pm. During this time the sun is at its weakest.
