I have always been drawn to the suns healing rays growing up.
If it is sunny, I ALWAYS take the time to absorb the suns healing energies.
Oslo Hospital,in Norway has balcony's for each patient and wheel the patients into the sun for hormone homeostasis treatments creating natural Vitamin D to heal their conditions..
Even cloudy days has 31% of full spectrum sunlight. So morning sun in cloudy weather is good too.
Very correct Haejin, morning sunlight does get thru the cloudy days.
