Do not ignore them as they can be fatal / 6 warning signs that you lack vitamin D

About 1 billion people worldwide are estimated to be deficient in vitamin D. The number is massive and this deficiency can cause many health problems. Of course, these symptoms are not caused only by this deficiency, but it can be one of many reasons. Whatever the case, you should always consult your doctor if you think you have any of the symptoms we mention below.

1. Hair loss or thinning

Vitamin D is essential for skin cells that process keratin, the protein needed to grow our hair and nails. So when there isn't enough, keratin isn't produced at the levels needed. In fact, vitamin D deficiency is often associated with alopecia and thinning hair in both men and women.

This vitamin plays a very important role in having a healthy sleep. Studies have shown that the lack of this vitamin can lead to insomnia, sleep interruptions.

One of the shields that your body and immune system can have as protection against disease and viruses is vitamin D. So when your body lacks this vitamin, it is much easier for you to get infected with viruses and get sick often. Colds, bronchitis and pneumonia can occur much more easily when vitamin D is lacking. In other words, this vitamin is very important for strengthening the immune system.

Studies have shown how vitamin D deficiency increases the chances of having rheumatoid arthritis at an older age. This is because vitamin D helps maintain bone mass in our body by aiding in the absorption of calcium. Another scientific review showed that people who suffered from chronic muscle pain and other bone-related problems tended to have lower vitamin D levels.

5. You feel tired all the time

Fatigue can have many causes, including stress, anxiety, depression, and vitamin D deficiency. A study involving 480 people with vitamin D deficiencies showed that they all experienced fatigue. This is because weaker bones and muscles can make your whole body feel more tired.

6. Wounds take longer to heal

People with diabetes are known to have difficulty healing their wounds, but if you don't suffer from this, then you are probably deficient in vitamin D. This vitamin has been shown to affect the growth of new tissue.

How to increase vitamin D levels

Food sources: fish, egg yolks, milk and yogurt are good sources of vitamin D.

Supplements: you can ask your doctor about the dose that is best for you to consume each day. But you don't need a prescription to take vitamin D supplements, as you can buy them over the counter.

Getting sunlight: While this is the most natural way to get vitamin D, you need to be careful about the time of day you are exposed to sunlight. It is best if you apply sunscreen 20 minutes before going out in the sun and avoid the time period between 10:00 and 16:00. Be sure to reapply sunscreen after an activity, such as swimming, or after 2 hours of first application
