Sunlight exposure during the day can be good for your eyes
Jul 20, 2021

Researchers found that those with higher sunlight exposure during the day had significantly higher levels of macular pigment, which prevents age-related vision loss.

Summer is a sight for sore eyes in more ways than one. A study by the Nutrition Research Centre Ireland has found that diet and daytime exposure to sunlight are the two key factors behind good eye health.

Based on a comparison between Mexican and Irish population samples, the study found that Mexicans had significantly higher levels of macular pigment.

Low levels of this pigment have been proposed to be a risk factor for macular degeneration, the leading cause of significant vision loss usually found in those over 55. This pigment is also known to protect the retina from damage by absorbing harmful blue light.

Nutrition: Top up on vitamin D when the sun shines
Jul 19, 2021

WE are set for some beautiful weather this weekend, so let's make the most of it and get outside to those vitamin D levels topped up.

Vitamin D has been hot news in the last few years, and the Covid pandemic has thrown new light on its importance for immune support.

We have known for some time that vitamin D does a lot more than just protecting us from developing rickets. From cardiovascular support to immune balance, mood and muscles, this is a hard working fat soluble vitamin, that has effects on every cell in your body.

Sunshine and SPFs

Although it is an essential nutrient, the main source of vitamin D isn't food, but sunshine. Our skin makes vitamin D when it comes into contact with the sun's UVB rays.

Using sunscreen is essential to protect our skin from the damaging effects of the sun's rays, but it does stop vitamin D synthesis, so although it is important to wear an SPF, it is also a good idea to get about 15 minutes of unprotected sun on your skin most days during the summer, taking care not to burn.

Turns out getting enough sun may protect you from cancer
Jul 12, 2021

  • Inadequate exposure to ultraviolet light is linked to colon cancer. 

  • • A lack of UV light may reduce levels of vitamin D.

• Vitamin D can also be found in many common foods.

Can tanning help fight developing cancer?

While tanning has been linked to skin cancer, a new study found that not receiving enough sun could result in a greater risk of developing colorectal cancer, also known as colon cancer.

Researchers at the University of California-San Diego said deficient exposure to ultraviolet light from the sun may increase colorectal cancer risk because meager amounts of UV light can reduce levels of vitamin D.

Scientist Prue Hart: ‘Sunburn causes havoc in the skin – we should avoid it’
Jul 12, 2021

The inflammation researcher explains the health benefits and dangers of soaking up the sun

Prof Prue Hart is head of the inflammation research group at the Telethon Kids Institute in Perth, Australia, which studies the beneficial effects of sunlight exposure on our health and whether these are the result of UV-induced vitamin D or other molecules produced in our skin upon exposure to sunlight.

What exactly happens when the sun hits our skin?
Sunlight is made up of three components: there’s the visible light that gives colour to everything we see; infrared light, which provides the heat; and ultraviolet (UV) light, which is probably the most important for our health.

Taking Vitamin D supplements during coronavirus infection beneficial, dips levels of cytokine storm: PGIMER meta-analysis
Jul 08, 2021

As Covid-19 continues to affect lives, the search for an effective therapy remains elusive. Accordingly, multiple existing drugs have been repurposed for the management of coronavirus infection. In this context, the role of Vitamin D, a fat-soluble vitamin, which is primarily related to bone and mineral metabolism in Covid-19 management has been debated several times, with some data diminishing its role and some studies indicating its benefits in Covid-19.

Considering the heterogeneity in the available clinical evidence, a present systematic review and meta-analysis was undertaken by PGI doctors to provide a precise summary and collate the effect of Vitamin D supplementation on adverse clinical outcomes in Covid-19 patients. Summarising the hitherto available clinical evidence, doctors at PGI, have recently published a study in the Journal of Endocrinological Investigation titled, ‘Vitamin D supplementation and clinical outcomes in Covid-19: A systematic review and meta-analysis.’

Best Ways To Soak Up Vitamin D While At Home
Jul 07, 2021

Repeated lockdowns during the coronavirus pandemic have taken a toll on our lifestyle in more ways than one. One drawback of being forced to stay indoors has been spending little time in the sun. Since sunlight is the main source of vitamin D, not getting enough sunshine -- whether we can help it or not -- puts us at risk of vitamin D deficiency.

Here's what you can do to make sure you get enough vitamin D while at home.

Unlike most vitamins, which are absorbed through diet, vitamin D is produced by the body as a result of direct sunlight exposure on the skin. While there are some foods and supplements that can help, the best source of vitamin D remains soaking up some sunshine, hence its "sunshine vitamin" moniker.

As such, not spending enough time outdoors can have a long-term adverse effect on the mind and body alike, depriving you of this essential vitamin.

According to the Mayo Clinic, vitamin D is crucial for bone health.

Over 100 Scientists, Doctors, & Leading Authorities Call For Increased Vitamin D Use To Combat COVID-19
Dec 10, 2020

By Dr. Karl Pfleger, PhD AI & Computer Science, Stanford University

To all governments, public health officials, doctors, and healthcare workers,

Scientific evidence indicates vitamin D reduces infections & deaths.

Research shows low vitamin D levels almost certainly promote COVID-19 infections, hospitalizations, and deaths. Given its safety, we call for immediate widespread increased vitamin D intakes.

Vitamin D modulates thousands of genes and many aspects of immune function, both innate and adaptive. The scientific evidence1 shows that:

  • Higher vitamin D blood levels are associated with lower rates of SARS-CoV-2 infection.
  • Higher D levels are associated with lower risk of a severe case (hospitalization, ICU, or death).
  • Intervention studies (including RCTs) indicate that vitamin D can be a very effective treatment.
  • Many papers reveal several biological mechanisms by which vitamin D influences COVID-19.
  • Causal inference modeling, Hill’s criteria, the intervention studies & the biological mechanisms indicate that vitamin D’s influence on COVID-19 is very likely causal, not just correlation.

UV→D NOW – Understanding the importance of sun exposure for health
Nov 12, 2020

By Perry Holman, Executive Director, Vitamin D Society

COVID-19 has spawned an entirely new angle of ultraviolet and vitamin D research in 2020 – bringing the role of UV and vitamin D into the health of your immune system into the forefront once again.

Research studies over the past 6 months have been consistent: People with higher vitamin D levels, naturally produced when your skin is exposed to UVB light from the sun, have a reduced risk of catching COVID-19 and a less severe outcome if they do contract the virus 1, 2, 3, 4, 5.

COVID-19 cases dropped substantially during our Canadian summer when people were out in the sunlight making vitamin D in their skin.

This is why we are focusing Vitamin D Awareness Month in 2020 on the main source of vitamin D: sunshine.

Did the sunlight deficiency pandemic lead to another?
Jul 16, 2020

by Dr. Gerry Schwalfenberg MD, CCFP, FCFP

Why do some people die from COVID-19, and others do not? As we re-open our economies, how can we manage risks and protect ourselves.  We know age and some diseases place us at increased risk but these may not be modifiable. What can we modify?

I have been researching the effects of vitamin D on the human body for about 15 years, and I’m struck by how low levels of vitamin D seem to be correlated to higher risk from COVID-19.

You can get vitamin D from various sources, but the most common source is sunlight. Exposing your skin to sunlight, without burning, increases your vitamin D levels. Inevitably, certain populations and certain countries spend more time outside. You can see the impacts on vitamin D levels, and we may also be seeing those impacts on COVID-19 levels.

Strengthen Your Immune System to fight COVID-19 - World Vitamin D Day - November 2nd

NEWS RELEASE
For Immediate Distribution

TORONTO, Ont (October 28, 2020) – Maintaining natural optimal vitamin D levels may be right up there with social distancing and wearing a mask as the most important actions you can take this winter to reduce your risk of contracting COVID-19, as well as helping your immune system reduce the severity of a case. 

That’s the message from new research the vitamin D research community wants Canada to hear on Nov. 2 -- the 11th Annual World Vitamin D Day. An estimated 93 percent of Canadians still have deficient vitamin D levels.

“Research is starting to show the importance of Vitamin D in strengthening your immune system and possibly reducing your risk/severity/death of COVID-19,” says Vitamin D Society Executive Director Perry Holman. “Increasing your daily intake of vitamin D is an action you can take immediately to safeguard your health until a COVID-19 vaccine becomes available. Many people have deficient or insufficient vitamin D levels. As we celebrate the 11th anniversary of World Vitamin D Day on Nov. 2, please evaluate your vitamin D intake and increase it to COVID-19 fighting levels.”

Here’s how:

World Vitamin D Day - November 2nd - STOP Vitamin D Deficiency

NEWS RELEASE
For Immediate Distribution

TORONTO, Ont (October 25, 2019) – People around the world are losing their battle against vitamin D deficiency and more and more are becoming vitamin D deficient. It’s estimated that more than 1 billion people have low vitamin D levels in the world. This occurs because we are living, working, and spending more time indoors than ever before. We are now told to apply sunscreens every day, year round, which if applied properly prevents vitamin D production. Up to 90% of your vitamin D comes from sunlight. Without unprotected sun exposure (when the UV Index is above 3 and your shadow shorter than you are) we cannot make vitamin D naturally in our skin. Vitamin D levels drop rapidly as the sun becomes weaker in the autumn. This is why we celebrate World Vitamin D Day every November 2nd. We want to warn you that you are probably Vitamin D deficient or insufficient right now.  People need to take action to increase their vitamin D intake. It’s time to STOP vitamin D deficiency and take back your health!

This is the 10th year of celebrating World Vitamin D Day on November 2nd as part of Novembers Vitamin D Awareness month to highlight peoples plunging vitamin D levels. This is a day for you to evaluate your vitamin D intake and take action to prevent deficiency since outdoor sunlight is now too weak to make vitamin D naturally in your skin at latitudes above 37°. Optimal vitamin D is needed throughout the winter to protect your health. A new World Vitamin D Day website has been developed to help inform people on the importance of maintaining optimal vitamin D blood levels of between 100-150 nmol/L (40-60 ng/ml USA). Please consider sending out one of the new social media shareables to your friends, family and loved ones on your social network to help promote vitamin D health. Remember to include the special hashtag #WorldVitaminDDay.

New Study Urges Change for Public Health Sun Exposure Guidelines

NEWS RELEASE
For Immediate Distribution

TORONTO, Ont (January 23, 2019) – A new research paper has shed light on the benefits of moderate non-burning sun exposure and calls for an immediate revision of current public health sun directives. It found the public has been misled and not fully informed of the health consequences if they avoid sun exposure. The authors concluded “that non-burning UV exposure is a health benefit and – in moderation – should be recommended as such.”

The commentary, prepared by internationally recognized experts, was published in the International Journal of Environmental Research and Public Health in December. UV radiation is the primary source of vitamin D for people and has been associated with lower disease rates for serious diseases such as some specific cancers, multiple sclerosis, diabetes, cardiovascular disease, Alzheimer’s disease, osteoporosis and age related macular degeneration.

The paper pointed out that the public is confused regarding sun exposure. Messaging to avoid “over exposure” is not clearly defined. What is “over exposure?” In addition, the current sun guidelines are clearly aimed at the northern European Caucasians portion of the population and may not apply for darker skinned populations whose skin can naturally absorb greater sun exposure and who are usually more vitamin D deficient.
