With the winter months coming, more people suffer from depression and SAD (Seasonal Affective Disorder)
Many medical experts believe depression and SAD are more prevalent in the winter due to the lack of light and sunshine. I believe it is more due to the lack of vitamin D3 which can only be produced in the body from light and sunshine. More diseases occur in individuals when living in areas further away from the equator than those who live near the equator. MS is more common in areas further away from the equator. MS is unknown in areas near the equator. With the combination of sunlight and sufficient exposure of our skin to the sun for 20 to 30 minutes several times a week, we manufacture our own vitamin D3 providing that we have plenty of cholesterol and we are not on statin drugs. If you are overweight or obese you will hold on to your vitamin D3 and it will not be available to the metabolic function. If you have dark skin you will not utilize vitamin D3 effectively. If you live in the northern latitude you will not find vitamin D3 effective from sunshine. The best way to make sure you have adequate levels of vitamin D3 is to take a supplement of vitamin D3. For best, optimal levels, have your physician do a vitamin D3 test. Your levels should be between 60 nanograms per ml of blood to 80 nanograms per ml. Many experts recommend approximately 5,000 IUs of vitamin D3 daily. In winter, some believe 10,000 IUs of vitamin D3 are justified. Currently there is research going on at the University of Oregon where researchers believe the level should be between 15,000 and 20,000 IUs daily. This is a huge increase in proposed daily dosages. I do not recommend these dosages until you consult with your physician. These are ongoing studies and not confirmed to provide the advice to take these dosages.
