Vitamin D deficiency has become a silent global issue today. How much time do you spend in the sun every day? If this question were asked to everyone in the world, their answer would probably be, “Very little, or perhaps none at all.” Some might even ask, “What benefit do we get from spending time in the sun?” Others might think that spending time in the sun is a waste of time.
Yes, I know—we’ve all become accustomed to living in such conditions that we can’t even stand in the sun for a short while, am I right?Have you ever felt like your body is gradually weakening? I mean, a person who was considered old after 60 in the past is now considered old at just 40.
The main reason for everything—from heart attacks at 40 to extreme fatigue while walking—is the lack of essential nutrients in our bodies. We’re so busy with our hectic lives that we don’t even realize our bodies are gradually becoming deficient in vital nutrients.
Vitamin D is one of the most essential nutrients for maintaining a healthy body. Did you know that we get vitamin D from sunlight, one of the best natural sources of vitamin D? And sunlight, unlike most things, doesn’t need to be purchased—it’s freely and abundantly available on Earth. That’s one of the biggest benefits of sunlight you should never ignore.
You might be surprised to learn that vitamin D deficiency has become a global problem. If you don’t know, let me tell you that vitamin D plays a crucial role in strengthening our bones and acts as a powerful immune system booster. It also helps improve your mood, which means that if you’re deficient in vitamin D, your mood may also suffer. Some of the most common vitamin D deficiency symptoms include fatigue, bone pain, muscle weakness, and frequent illnesses.
Approximately 1 billion people—from the United States and Britain to India, Japan, and Australia—suffer from vitamin D deficiency. What are the main vitamin D deficiency causes worldwide? Are you also suffering from it? How do you know if you have a vitamin D deficiency, and if so, how can you address it? Let me briefly explain all of this so you don’t have to face any problems caused by a lack of vitamin D in your life, and so you understand how to get vitamin D naturally through sunlight and food sources.
Why is Vitamin D Deficiency a Global Problem?
If you think vitamin D deficiency only affects people in countries with limited sunlight, you’re completely wrong. This global health problem isn’t limited to a specific country or climate; it’s also common in countries with the highest levels of sunlight exposure. Vitamin D deficiency in people living in sunny areas is due to modern lifestyles and environmental changes. Let me explain some of the main causes of vitamin D deficiency that lead to serious vitamin D deficiency symptoms and health issues.
1) Limited Sunlight Exposure:
To avoid vitamin D deficiency, people should get morning sunlight, which is one of the best natural sources of vitamin D. However, nowadays, people spend less time in sunlight and more time in enclosed spaces, such as working long hours in air-conditioned rooms or spending long hours indoors watching mobile phones or television during holidays. Even if a person needs to go to a store outside their home, they take a car even though they could easily walk to it. Now, where will such people get sunlight, the main natural source of vitamin D for the body?
2) Use of Sunscreen and Covered Clothing:
Some people cover their entire body with clothing to prevent sunlight from reaching them, which leads to low vitamin D levels. How can they get vitamin D naturally? Some people want to protect their skin, so they apply sunscreen to protect their skin from UV rays, which are responsible for vitamin D synthesis. However, they are unaware that sunscreen also blocks UVB rays, which are essential for vitamin D production in the skin and can result in vitamin D deficiency-related health problems.
3) Dietary Deficiency:
Did you know that vitamin D can also be obtained from foods like eggs, fish, and fortified dairy products? Many people around the world avoid this type of diet, such as vegetarians, leading to one of the most common vitamin D deficiency causes.

If you choose to eat only vegetarian food all your life, there’s no doubt that you may develop a vitamin D deficiency due to lack of dietary sources.
4) Air Pollution and Latitude:
People living in some northern countries, such as Canada, the UK, or Scandinavia, receive fewer UVB rays from sunlight exposure, which can lead to a vitamin D deficiency. There are also many highly polluted countries where air pollution blocks sunlight, preventing the skin from producing enough vitamin D. People living in these countries also face difficulty producing vitamin D due to low UVB exposure, resulting in a significant vitamin D deficiency.
Common Symptoms of Vitamin D Deficiency
Vitamin D deficiency may not be immediately apparent because it’s a quietly developing health issue. The early symptoms of vitamin D deficiency become noticeable only when your body begins to experience significant declines. Every illness gives us some warning signs before it becomes serious. So, let me share some early warning signs of vitamin D deficiency that appear before the condition becomes severe. Read carefully and see if you’re experiencing these signals from your body. If you are, get your vitamin D levels checked immediately.

How to Increase Vitamin D Naturally: Simple Daily Tips
Many people around the world who suffer from vitamin D deficiency may have one question: how can they overcome it naturally? If you have this question, let me give you a brief answer on how to boost vitamin D levels effectively.
1) Spend some time in the sun every day
Spending time in the sun doesn’t mean standing in the harsh afternoon sun and falling ill the next day. Spending 15 to 20 minutes in the morning sun every day is enough to get vitamin D naturally. Morning sun refers to sunlight that comes before 10:00 AM. In some countries where sunlight comes later, people can spend any favourable time between 10:00 AM and 12:00 PM to increase vitamin D production naturally.
2) Exercise outside
Going out in the morning sun and engaging in regular exercise, such as walking, cycling, or yoga, can help you boost vitamin D naturally.

Exercising in the sun provides two benefits: first, your body will produce vitamin D naturally, and second, exercise will keep your body healthy and strong.
3) Include vitamin D-rich foods in your diet daily
If you can’t get out into the sun every day due to a busy lifestyle, you can include vitamin D-rich foods in your diet. Foods such as eggs, fatty fish, and fortified dairy products can help maintain healthy vitamin D levels naturally.
4) Consider dietary supplements
If you don’t have time to get sunlight or include vitamin D-rich foods in your diet, taking vitamin D3 supplements is a safe and effective way to overcome vitamin D deficiency.

Before starting any supplement, consult your doctor to ensure it’s right for you.

While everyone is at risk for vitamin D deficiency, some groups of people are more likely to be affected. Understanding vitamin D deficiency risk factors can help you maintain healthy vitamin D levels and prevent related health problems.
