How Long in the Sun for Vitamin D? Vitamin D Test in London.
By Mr. Tharb Faisl
You’ve probably heard that getting sunshine boosts your vitamin D – but how much sunlight is really enough? And what if your body isn’t absorbing it properly?
With fatigue, low mood, muscle aches, and bone thinning on the rise across the UK, vitamin D deficiency is now one of the most common – and overlooked – health issues. At Marylebone Diagnostic Centre, we offer quick, private vitamin D testing in central London, helping you get the answers and support you need in just one visit.
How Much Sunlight Do You Really Need for Vitamin D?
In the UK, getting enough sunlight can be challenging — especially during the darker months.
- Spring & Summer: 10–20 minutes of direct sunlight on your arms and face, 2–3 times per week, is typically enough for many people.
- Autumn & Winter: Sunlight is often too weak to trigger vitamin D production, even if it’s bright outside.
- At-Risk Groups: People with darker skin, older adults, indoor workers, and those who wear covering clothing may need more exposure or consider supplements.
And while sunscreen is vital for skin protection, it can block your body’s ability to produce vitamin D. So even in summer, your levels might still be low.
Signs You Might Have Low Vitamin D
Vitamin D deficiency symptoms can be subtle — but they can deeply impact daily life. Look out for:
- Constant fatigue or tiredness
- Low mood or signs of depression
- Weak muscles, joint pain, or body aches
- Frequent infections or slow recovery
- Hair thinning
- Bone pain or increased fracture risk
Long-term deficiency has been linked to osteoporosis, poor immune response, and even cardiovascular disease.
