Can You Get Vitamin D Through Window?

can you get vitamin d through window

Have you ever wondered, "Can you get vitamin D through window?" It's a common question, especially if you're living in less sunny climates.

The short answer is: not really. Glass window panes typically block out harmful UV rays, which are responsible for vitamin D synthesis, making absorption through a window difficult.

This limitation can significantly impact your vitamin D intake, particularly during colder Canadian winter months or if you spend most of your time indoors.

In this blog post, we at Vitamart will explore how much vitamin D actually comes through a window, why this nutrient is essential for your health, and alternative ways to ensure you get enough vitamin D.

What this article covers:

How Much Vitamin D Comes Through a Window?

When it comes to getting vitamin D from the sun, windows pose a significant barrier. Most standard glass windows block harmful UV-B rays, which are responsible for vitamin D production in your skin.

While some UV-A rays may pass through a glass window, they ultimately don't contribute to vitamin D synthesis.

After conducting experiments with it, we found that sitting by a closed window, even on a sunny day, doesn't produce vitamin D compared to direct sunlight exposure from time spent outdoors.

However, it's worth noting that the amount of vitamin D absorbed into your body can vary depending on factors such as the:

  • time of day
  • geographical location
  • type of glass

For instance, special UV-transmitting windows can allow more UV-A rays to pass through, which is less harmful than UV-B and UV-C rays. However, these customised glass windows aren't commonly used in residential settings and don't synthesise vitamin D production.

As such, relying on sunlight through windows for vitamin D is generally ineffective.

Why Is Vitamin D Important?

Based on our first-hand experience, vitamin D plays a critical role in numerous bodily functions, making it essential for your overall well-being.

Let's explore two key areas where vitamin D is particularly important:

Calcium Absorption And Bone Health

One of the primary functions of vitamin D is to aid in calcium absorption.

Without sufficient vitamin D, your body will struggle to absorb calcium from the foods you eat, regardless of how calcium-rich your diet may be. This can lead to weakened bones and an increased risk of fractures.

Vitamin D works in tandem with calcium to build and maintain strong bones, which is critical as you age.

It also helps prevent conditions like osteoporosis and rickets, ensuring your skeletal system remains robust throughout your life.

Supporting A Healthy Immune System

Beyond its role in bone health, vitamin D is also pivotal for maintaining a strong immune system.

It helps regulate the production and function of immune cells, enhancing your body's ability to fight off infections and diseases.

Our investigation demonstrated that individuals with adequate vitamin D amounts often experience fewer respiratory infections and may even have a reduced risk of autoimmune disorders.

This immune-boosting property of a vitamin D supplement and natural sources have gained increased attention in recent years, highlighting vitamin D's significance in overall maintenance and well-being.

Other Ways to Get Vitamin D

Given that you can't rely on sunlight through windows for your vitamin D needs, here are some effective ways to ensure you're still getting enough of this vital nutrient:

Eat Foods With Vitamin D

Incorporating vitamin D-rich foods into your diet can help boost your levels.

For example, fatty fish like salmon, herring, and sardines are excellent sources of vitamin D. Additionally, egg yolks, mushrooms enriched by UV light, and fortified products such as milk, cereals, and orange juice can also contribute to your daily intake.

However, it's important to note that vitamin-D-rich meals alone won't provide sufficient vitamin D for many people. This especially pertains to those living in northern latitudes or with limited sun exposure, such as here in Canada.

Take Vitamin D Supplements

Through our practical knowledge, we know that supplements are the best way to take vitamin D consistently.

Supplements come in various forms, including:

The dosage can vary depending on individual needs, age, and current vitamin D quantities. It's always best to consult with a medical professional to determine the right quantity for you and your loved ones.

When choosing a supplement, look for high-quality products from reputable brands to ensure you're getting the most benefit.

Get A UV Lamp

UV lamps designed can be an optimal substitute for vitamin D production.

Based on our observations, these lamps emit UVB rays similar to sunlight, stimulating vitamin D synthesis in the skin.

UV lamps can be an effective option for learning how to increase vitamin D levels, especially during the colder winter months in Canada or for individuals with limited outdoor access.

However, it's crucial to use these lamps carefully by following manufacturer instructions to avoid overexposure and potential skin damage.
