Here are four common symptoms of vitamin D deficiency that you should be aware of.

Some of us aren’t getting as much sunshine as we’re used to right now.  Vitamin D is synthesized in the skin in response to sunlight exposure.  Without the sun, we are more at-risk of vitamin D deficiency. It is estimated that around 1 billion people experience this condition all over the world. How do you know if you’re lacking vitamin D? Below are four common symptoms of vitamin D deficiency that you should be aware of.

1. Fatigue– There are many causes of fatigue, and vitamin D deficiency might be one of these. However, many people often ignore this as a possible cause. When your body doesn’t have sufficient vitamin D, it reduces the levels of blood, thus reducing the amount of oxygen and nutrients to important parts of the body. You might experience chronic headaches and daytime fatigue, which can reduce your life quality if left untreated. A temporary solution for this issue is to take vitamin D supplements, which might help boost your energy levels.
2. Back Pain– Most of us know how crucial vitamin D is in maintaining healthy bones. Vitamin D improves the absorption of calcium, one of the main components of your bone structure. That’s why lower back and bone pain might indicate low vitamin D levels in your blood. Many studies have recently found that people with a vitamin D deficiency might be more likely to experience back pain, joint pain and muscle aches.
3. Frequent Illness– Vitamin D plays an essential role in maintaining a healthy immune system. A deficiency of this mineral can reduce your ability to fight against bacteria and viruses causing illnesses. So, if you find yourself frequently ill, particularly with the flu or colds, then a low level of vitamin D might be a possible cause. Many studies have also shown an association between this condition and respiratory infections, such as pneumonia, bronchitis, and colds.
4. Excessive Perspiration – A sweaty head might be one of the first symptoms of vitamin D deficiency for many people. This is particularly true when you sweat in a way that you normally would not. It might occur during a period of inactivity or mild temperatures. This condition might indicate that the internal temperature of your body is rising due to the attacks of some foreign bacteria or viruses. While sweating might be good for your health as it releases toxins, excessive sweating might indicate an underlying health problem.
