A healthy
vitamin D level
throughout the year

Sunlight plays an important role in various bodily functions, often related to the production of vitamin D. A daily low dose of ten minutes of sunlight is enough for a healthy vitamin D level.Unfortunately, most people are not able to get even that much during the autumn and winter months. That is why 70% of West Europeans have a vitamin D deficiency in autumn. Research shows that daily use of Sunshower products with a low UV dose during the winter months doubles the vitamin D level.*

Vitamin D is the only vitamin that the human body can produce itself. When the skin is exposed to UV or sunlight, it produces the pre-vitamin D3, which the liver and kidneys then convert into vitamin D. This process is boosted by UV-B radiation. Scientific research shows that the list of physical processes affected by vitamin D is getting longer every year.

Scientific evidence 

Scientific research has shown that vitamin D affects physical processes (positively).  For example, vitamin D is responsible for:

  • stimulation of the immune system
  • absorption of calcium
  • development and maintenance of muscle functions
  • suppression of infections
  • development and maintenance of cognitive functions

Stimulation of the immune system

It has been shown that a daily low dose of vitamin D supplementation has a positive effect on our immune system. This makes our immune system not only stronger but also more efficient. The immune system not only suppresses the foreign substance, but also suppresses the immune system. This makes the physical response to an antigen more effective, reducing signs and symptoms. With a five-minute session of the Sunshower’s sunlight three times a week, doubling the vitamin D level is achieved in three months, making it a very healthy choice for protecting yourself against viruses and other diseases.

Calcium absorption: good for bones and teeth

Vitamin D3 stimulates the absorption of calcium from the intestine and ensures the mineralization of the bones. Research shows that this can limit bone loss in old age and positively influence bone density. In addition, this process can also reduce the risk of bone fractures; after all, the bones remain powerful. Calcium also helps to keep the teeth strong.

Development and maintenance of muscle functions

Vitamin D deficiency results in muscle weakness and muscle cramps. Sufficient vitamin D ensures a better sense of balance and the maintenance of muscle strength in old age. This way, sufficient vitamin D reduces the risk of falling.

Effects on cell differentiation

The Dutch cancer fund KWF  is conducting large-scale research into sunlight and vitamin D. One of the main conclusions from the studies is that vitamin D can prevent colon cancer. In addition, another scientific study into the relationship between sunlight, vitamin D and cancer shows that a daily dose of sunlight is important for a healthy vitamin D level. The study also showed a relationship with a reduced risk of colon, prostate and breast cancer, among others. This means that vitamin D can have a preventive effect on various cancers.
