Not getting enough sunlight could increase your risk of getting cancer, study findsJuly 6, 2021
NOT getting enough sunlight could increase your risk of getting cancer, a study has found.
Lower UVB exposure is associated with colorectal cancer, particularly in older age groups.
Researchers at the University of California San Diego investigated links between levels of UVB light in 2017 and rates of cancer for different countries and age groups in 2018.
They used data from 186 countries and published their findings in the journal BMC Public Health.
The experts found lower levels of UVB exposure – a lack of sunlight – could reduce Vitamin D levels.
Lower Vitamin D has been linked to an increased risk of colorectal cancer before.
Therefore, by correcting any Vitamin D deficiency, it could drastically cut the chances of developing cancer.
The association between lower UVB and risk of colorectal cancer remained significant for those aged above 45 after other factors, such as skin pigmentation, life expectancy and smoking were taken into consideration.
Raphael Cuomo, co-author of the study said: "Differences in UVB light accounted for a large amount of the variation we saw in colorectal cancer rates, especially for people over age 45.
CUTTING CANCER RISK
"Although this is still preliminary evidence, it may be that older individuals, in particular, may reduce their risk of colorectal cancer by correcting deficiencies in Vitamin D."
Getting out in the sun can not only help you stave off cancer – although, one always has to be sun safe to prevent skin cancer – it can have other health benefits.
It can boost your mood, help you sleep better and keep your bones strong.
Sun exposure helps the body make Vitamin D naturally – a mineral many people in Britain don't have enough of.
It's difficult to get from food alone, but it can reduce depression and boost your immune system.
If you don't have enough in your system you can suffer from fatigue, hair loss and muscle pain.
But always take care in the sun and wear sunscreen, drink lots of water and keep a hat on.
