Natural vitamin D sources mainly come from sunlight, but not every working group has the conditions to fully expose to sunlight. Therefore, determining industries that should supplement vitamin D is necessary to prevent long-term health problems.
Office workers are at high risk of vitamin D deficiency. The specific nature of sitting in a closed room, working with computers from morning to afternoon makes them less exposed to sunlight. Prolonged this situation can lead to premature osteoporosis, muscle and joint pain and reduced resistance. Therefore, office workers should proactively supplement vitamin D through foods such as egg yolks, salmon... or oral tablets as recommended by medicine.
Next is the group of workers working in shifts, especially night shifts such as factory workers, medical staff, security guards or 24/7 service providers. The reversal of the circadian rhythm makes it difficult for them to be exposed to sunlight at the appropriate time for vitamin D synthesis. The consequence is that the body is prone to vitamin D deficiency, affecting bones and joints and sleep quality. For this group, periodic vitamin D supplementation is a solution that needs to be considered.
Workers working in sun-protected environments are also at high risk. Miners, mechanics in closed workshops, cold storage workers or people working in industrial parks with little natural light often do not have enough conditions to synthesize vitamin D through the skin. Although working hard and consuming a lot of energy, vitamin D deficiency can make them easily tired, have painful bones and joints and reduce labor productivity.
In addition, some outdoor workers may still be deficient in vitamin D if they regularly wear protective clothing, use sunscreen or work in the early morning and late afternoon. This shows that it is not only the factor "outdoor or indoor" but also depends on the time and level of sun exposure.
Combining sunbathing appropriately, eating rich in vitamin D and consulting health experts when needed will help workers protect bone and joint health and improve the quality of life.
