Importance Of Vitamin D3 In Human Body – Devices are only intended to stimulate the production of endogenous vitamin D for the treatment and prevention of vitamin D deficiency.

We have long harnessed the power of sunlight to prevent infections, ward off disease and cure illness. There’s a reason why we naturally enjoy soaking up the sun’s rays on a nice day; beneficial biomolecules are activated when your body is exposed to light, positively affecting both body and mind. These healthy photo byproducts act as anti-inflammatories, vasodilators (which help lower blood pressure), and endorphins. They keep your body strong and your mind focused.

Importance Of Vitamin D3 In Human Body

The benefits of sunlight have been well documented throughout history. Nursing pioneer Florence Nightingale observed during the Victorian era that sick patients in rooms with ample sunlight recovered more quickly than those in rooms without windows. This reflection, along with others, laid the foundation for a modern approach to science and medicine.

What Is The Use Of Vitamin D3 Injections?

Vitamin D production is one of the best-known health benefits activated by sunlight exposure. For our skeletal, cardiovascular, neurological and immune systems, maintaining proper vitamin D levels protects against disease, optimizes physical performance and improves mental health. Keep reading to discover the full benefits of sunlight and vitamin D – also known as the sunshine vitamin.

Vitamin D is often called the sunshine vitamin because the skin’s production of vitamin D3 is activated by the sun’s ultraviolet B (UVB) rays. Despite being called a vitamin, vitamin D is actually a hormone produced in the body.

Vitamin D is naturally produced when UVB light is absorbed through the skin, converting a specialized cholesterol into pre-vitamin D3. Pre-vitamin D3 is then converted into vitamin D3 in the skin and is transferred into the bloodstream over several days. After vitamin D arrives in the liver, it requires two metabolic conversions to become calcitriol – the active form of vitamin D. Calcitriol binds to vitamin D receptors in almost every cell of the body.

Although it sounds complicated, this process is regulated naturally by the body. Vitamin D bioavailability is managed by several internal control mechanisms to ensure your body gets only what it needs. When vitamin D levels are maintained, this hormone strengthens your immune system, making you ready for any physical or mental challenge that comes your way.

Studies have shown that vitamin D deficiency is widespread, with approximately 77% of the world’s population experiencing low levels of vitamin D [1, 2]. Awareness of the importance of vitamin D’s role in overall health is crucial to living the healthiest life possible.

While spending time in the sun sounds simple, the shift from an agricultural society to today’s information age has had a direct impact on our lifestyles – which now include spending hours in front of a computer screen. Our indoor society is exposed to much less sun than previous generations.

When we make time to enjoy the beauty of the outdoors, all too often we cover our arms, legs and faces with lightweight clothing and wide-brimmed hats. This is in large part due to increased awareness of the risks of sunburn and skin cancer, and the prevention of premature skin aging. Such awareness has led to better protection against the sun’s harmful UVA rays. However, these measures also block beneficial UVB rays, which has resulted in epidemic levels of vitamin D deficiency [3].

Maintaining proper levels of vitamin D is vital for overall health and well-being. A sunshine vitamin deficiency is correlated with more than 53 disease states, including breast cancer, multiple sclerosis, osteoporosis and rheumatoid arthritis, as well as a host of mental health conditions.

The Importance Of Vitamin D In Getting And Staying Healthy

Not yet convinced of the health benefits of sunlight exposure? Just look at the science. Daily exposure to sunlight has been shown to reduce the incidence of multiple sclerosis, type 1 diabetes, high blood pressure, and even the incidence and mortality of several cancers.

A 20-year study of approximately 30,000 subjects found that those who avoided sun exposure were twice as likely to die from any cause [4]. This study confirms several previous studies that found reduced sun exposure is a risk factor for all-cause mortality.

A 20-year study of about 30,000 subjects found that those who avoided sun exposure were twice as likely to die from any cause.

The literature also points out the correlation between lack of sunlight and various conditions that have a major impact on the quality of life. This includes depression, bipolar disorder, suicidal thoughts and self-harm, as well as reduced cognitive performance. Such symptoms worsen during the winter months when natural sun exposure decreases. This change in mentality is no coincidence.

When exposed to sunlight, our skin produces various hormones and peptides that contribute to our systemic health and well-being. Substances formed from chemical reactions with sunlight are called photoproducts. Vitamin D3 is the most universally recognized health benefit, but it is just one of many.

All these substances contribute to that relaxed, happy feeling we get when we are regularly exposed to the sun. Nature reinforces sun-seeking behavior and UVB-synthesized photo products collectively harmonize to keep us healthy.

The optimal dose of vitamin D varies and depends on the individual. Studies show that sun exposure, which causes a slight pink color to the skin within 24 hours, has the potential to boost the body’s production of vitamin D by 15,000-20,000 IU [5].

The problem is that we’re all busy – and it’s hard to get enough sun exposure when you take into account the variables that need to be aligned: latitude, season, time of day, cloud cover, altitude, sunscreen use and pollution. To generate the optimal dose of vitamin D from the sun we need to expose our skin to direct sunlight when the atmospheric and geographical conditions are perfect.

To combat the winter blues and maintain healthy vitamin D levels year-round, many turn to vitamin D supplements. However, supplements are treated differently by the body than sunlight, meaning it is possible to consume large and potentially toxic amounts of vitamin D from supplements. This concern does not exist when considering natural sun exposure; if your body has enough vitamin D, it will simply produce less of it.

Research shows that while higher levels of vitamin D produced by the sun are helpful in preventing disease, supplements do not provide the same benefit. The discrepancy in the benefits of sunlight-induced vitamin D versus supplemental vitamin D can be explained by one fact: the correlation between higher blood vitamin D levels and disease prevention in epidemiological research is measuring sun exposure, not measuring of additional vitamin D.

Population studies have repeatedly shown that sun exposure makes a greater contribution to vitamin D concentrations than supplementation. Therefore, at the population level, vitamin D is a good proxy for sun exposure, and higher serum concentrations are an indicator of greater skin contact with sunlight [6, 7].

The assumption that vitamin D from supplements provides the same health benefits as vitamin D from light does not take into account the benefits of the sun beyond vitamin D production. It is important to understand that there are other vital elements that contribute to our systemic health. Although the contributions of each of these photo products are still being unraveled by researchers, one thing is clear: humans need exposure to UVB radiation for their physical and mental health and well-being.

Have Vitamin D3 And B12 Deficiency? Here’s Why You Shouldn’t Take It Lightly

Light therapy treatments, like those offered by , are a creative and innovative way to get the benefits of the sun without the harmful rays. was founded with the sole mission of making the world a healthier place, and it does just that by empowering us to unlock our natural healing powers using UVB light.

By capturing a very narrow spectrum of UVB light, also called ‘the spectrum of life’ (293 nm to 303 nm), the best properties of the sun are used to activate the natural production of vitamin D. This advanced treatment virtually eliminates the concerns associated with prolonged sun exposure. the benefits of the sun without the harmful UVA rays.

Vitamin D from light – natural or through a UVB light therapy treatment – ​​has a positive influence on body and mind. It is up to everyone to ensure proper levels of vitamin D are maintained to protect against disease, optimize physical performance and improve mental health.
