It seems impossible, doesn’t it? Living in a country with year-round sunshine and still being vitamin D deficient. But it’s a surprisingly common issue across the UAE and it could be affecting your mood, energy, immunity, and even your bones.
Sunshine State of Deficiency
Despite the abundant sun, studies show that up to 80% of people in the Middle East have low levels of vitamin D. Why? A mix of cultural clothing, indoor lifestyles, intense midday heat that keeps people out of the sun, and liberal sunscreen use.
The result? Your body isn’t converting enough UVB rays into active vitamin D, which plays a vital role in everything from calcium absorption to immune function.

Symptoms You Shouldn’t Ignore ▾
Vitamin D deficiency often goes unnoticed until it’s advanced. Here are some signs to look out for:
Why Vitamin D Matters ▾
Vitamin D acts more like a hormone than a vitamin. It influences hundreds of cellular functions and is crucial for:
- Strengthening bones and preventing fractures
- Supporting your immune system
- Improving mood and brain function
- Reducing inflammation
In kids, deficiency can lead to rickets. In adults, it contributes to osteomalacia (bone softening) and even osteoporosis.
How to Boost Your Levels
Sun exposure: 10-20 minutes of early morning sun on bare skin (without sunscreen) can help, especially on arms and legs.
Diet: Include fatty fish (salmon, sardines), egg yolks, mushrooms, and fortified dairy.
Supplementation: Especially during summer when outdoor time is limited.
