To make things easier, the Healthy Bones Australia Calculator works out if you’re getting enough daily sunshine exposure to produce enough vitamin D:

  • It takes into account factors such as your age, location in Australia, what time you were in the sun and for how long.
  • It tracks your history of sunshine exposure as sunshine has a cumulative effect over time.

If you’ve had enough daily sunshine, you get a big tick!


Disclaimer: There is a school of thought that people with darker skin require greater sun exposure for vitamin D absorption. eg 15 - 60 minutes during summer and 20 minutes to 3 hours during winter (depending on the latitude). At present the Healthy Bones Australia Calculator does not take this into account
