Indoor UV devices have been used throughout history as effective health-promoting tools by providing a source of artificial sunlight in place of sunshine exposure
Key Points
- The use and effectiveness of indoor UV devices have been demonstrated throughout history; when natural sunlight was unavailable, artificial sunlight generated by indoor UV devices was successfully used to fill the gap and can still be a great alternative to make vitamin D and get the other health benefits normally received from sensible full spectrum sunlight exposure
- When considering a source of artificial UV light, it is important to be aware of the type of UV or light emitted by the device, its safety, and the physiological effects it may produce, especially in terms of vitamin D
- Studies support the use of artificially derived UVB light to raise vitamin D levels when the UV index of the sun is low, especially in the winter months of northern countries; it is important to note that tanning beds may not be recommended for individuals with skin types that always burn – see the guidelines provided below, stay safe, and don’t burn
Both natural and artificial sunlight from indoor UV devices, when used with diligence, can act as major interventional tools to help prevent and heal diseases related to a lack of sunshine and/or vitamin D deficiency.
