With low levels of vitamin D proven to contribute to conditions such as atrial fibrillation, it is vital for older adults to ensure they are regularly exposed to the vitamin.
However, during the winter months having a vitamin D deficiency is very common because of the lack of sun.
Andrew Johnson, herbalist and nutritional therapist, is advising people to get themselves checked out so they can begin to take a vitamin D supplement should their levels be too low.
"This time of year, if you had to do one thing, that would probably be one of the most important things to do. It's a massive problem, and it's been largely overlooked," he said.
Taking a winter holiday can also be a great and fun way to top up vitamin D levels, in addition to helping you relax.
People with a vitamin D deficiency often experience feelings similar to those of depression, such as sadness.
A holiday can be essential for helping the body rejuvenate at this time of year.
