The simple answer is to get out into the sun. But how long do you actually need to spend outside? The answer depends on many different factors, such as the colour of your skin, how much skin is exposed and how intense the sunlight is.

The more skin you have exposed to the sun, the quicker your body will produce vitamin D. Too much UV from the sun causes sunburn, premature ageing and increases your risk of skin cancer. And you do really need to go outside to reap the benefits of sunlight. Follow StrongWomenUK on Instagram for the latest workouts, delicious recipes and motivation from your favourite fitness experts.

In an in-depth Cancer Research UK-funded study , Rhodes and her team looked at the impact of exposing 39 people of different skin types to low levels of UV.

Would that be enough to generate vitamin D? And will this cause DNA damage in their cells that could lead to skin cancer? As the dose of UV increased towards their individual burning level, there was an increase in both vitamin D levels and DNA damage seen in skin samples. For all skin types these factors seem to be completely intertwined.

One motivation for Rhodes is understanding more about difference between skin types. We needed to firm up our knowledge by looking at the major benefit and the major harm of sunlight at the same time in each person. Interestingly, the findings differed by skin type when the researchers looked at the lower layer of the skin, where damage is most dangerous.

In lighter skin types DNA damage was found throughout the layers, meaning there was more potentially dangerous damage lower down. Regardless of dose or skin type, the DNA damage was no longer present 48 hours later.

Our bodies can deal with some level of DNA damage and the level of damage in the study seemed to be low enough to be cleared shortly after. And Rhodes is keen to study this more in the future. Larger studies will be needed to confirm those results. There may not be a totally safe level of exposure to the sun when it comes to DNA damage and skin cancer risk, but we also need some sunshine to make vitamin D.

To do this, she teamed up with Professor Ann Webb, a physicist with expertise in the atmosphere and sunlight. This figure assumes that people would be in shorts and t-shirts for June to August, while only having their hands and faces exposed from March to June and for September. Little and often does seem to be the key. With the same conditions, even people with darker brown skin that hardly ever burns and easily tans — such as people of South Asian origin —and may only need 25 minutes.

The studies were based on several specific assumptions. For example, they considered exposure to sun in the UK without sunscreen, accounting for UK weather and no travel abroad. But they can help to give us a broad idea. After this 9 minutes is when sun protection becomes key. Click here to cancel reply. Bernard Jordan September 16,
