Having discovered I was very low in vitamin D and have osteopenia, I walk every morning in summer at around 7.15 am thereby getting the sun before the rays are so harmful and thereby getting some vitamin D.
In winter I have to take supplements.
While living on a farm, I used to actually sit outside after breakfast for 10 minutes as that is what my doctor told me was needed for Vitamin D. I preferred this to taking supplements.
No, I just got tested and was told I was really high on Vitamin D . The doctor suspected if I was taking tablets, LOL. She told me I must have got it from some countries I lived in couple of months ago...and my levels will go down if I am here for continuous 2 years. I hope not !
If only..... we have no morning sun here! I have a special lightbox to emulate early morning daylight which helps prevent SAD but doesn't help with Vitamin D. Nearly everyone in Northern Europe is Vit D deficient (it's impossible to make enough in the summer months to last through the winter) so my family all take hefty supplements of it. Not as good as the real thing but better than nothing....
I go walking in the morning, with a friend at 8am, weather the sun is shining for not, but not if it's raining. I've always had my breakfast after my walk & my shower, but I noticed on a tv show, that 1 can lose weight faster, by having breakfast 1st! But I find 7.30 is just to early for me to eat. I usually eat it at around 10am.
