Some frequently asked questions about sunshine’s UV rays and vitamin D:
1) Will sitting next to a sunny window indoors boost your Vitamin D levels?
Answer: No, most windows block the UVB rays (shorter wave) that generate Vitamin D naturally.
Details: Common windows allow much of the UVA rays (longer wave) to pass through which makes tanning possible, but there is not Vitamin D generated. – Note: Some modern construction is using glass that blocks all UV rays. Car windshields are made to block both UVA and UVB.
2) Can I overdose on Vitamin D from too much sunlight or sunlamp?
Answer: No, the natural ultraviolet light way of getting vitamin d will not do this. Overexposure can cause sunburn, but not vitamin d overdose. Our units all have automatic shut-off timers to help prevent the possibility of sunburn. And with supplements: it’s rare, but you can get overdose toxicity with ‘supplements’ which you can read about online with a simple article search. Also, some have gastrointestinal issues with supplements.
3) How does natural Vitamin D synthesis from UVB rays work?
4) Is getting Vitamin D from UVB rays (sunshine or Vitamin D sunlamp) different than taking a supplement pill?
“Not only does sunlight make vitamin D but also beta-endorphin, which makes you feel better,” Dr. Holick tells Newsmax Health. “There’s also nitric oxide, which can lower blood pressure, and a host of other substances that you would never get just by taking a supplement.”
Sun exposure can also help regulate circadian rhythm, lower blood pressure, ease depression, boost the immune system, and even reduce the risk of certain cancers, notes Dr. Holick, who recommends about five to ten minutes of unprotected exposure a day. – Source: NewsmaxHealth, by Gary Greenberg.
