Vitamin D is often called the “sunshine vitamin” because the body produces it after exposure to sunlight. However, modern indoor lifestyles, poor diets, and lack of sun exposure have made vitamin D deficiency increasingly common worldwide. According to health experts, millions of people may have low vitamin D levels without even realizing it.
The problem is that vitamin D deficiency rarely causes obvious symptoms at first. Instead, the body sends subtle signals that are often ignored or blamed on stress and exhaustion. Over time, these warning signs can become more serious and affect overall health.
