winter and christmas is a sad time for many .....
The holidays can truly be a sad time for those who are alone, for whatever reason.
But lack of vitmin D causes depression, too, and most get far too little, even in the summer, and it's worse in the winter. Sept. 21st, I started using my lamp again, and I won't stop, in the spring, until it's warm enough to get half-body exposure, outside. Window glass allows in the more deeply penetrating UVA, which causes cancer, but it blocks the UVB, which is protective against it..
RDA is 400 iu, and it takes about 8,000 iu/day for the average person to get over 50 ng/ml, which the science is now showing should be the minimum level.
Reference values were determined by averaging high numbers of hospital admission levels. Using those, the levels were set; the problem was/is that most of those people were low.
Same with the contention that seniors can't make enough from the sun; problem is that seniors get even less UVB than younger people.
I'll be 63 in a couple of months, and my Sept. level was 57, and I doubt that anyone on here has a higher level. I'm shooting for 70 on my April exam. Gov't says 30 is sufficient, but the science has gotten ahead of the bureaucracy. For those with cancer or heart disease, 70-80 is best. I hadn't taken supplemental D for 9 months, and unless you eat beef liver (not chicken) several times a week, you can't get enough from diet alone; we evolved getting it from sun, and it's still the best way. I get my D from UVB only.
If any want to know the reasons, or advice on the best lamp. PM me. I'll again post on it, in "health", though, because I think it is SO important. For pennies a day, and a little thought, many of this country's health problems could be greatly lessened. For one, mental health has been in the news lately, as it should be. D affects over 2,000 of our genes, and I can't think of another one thing that does so.
I don't know what the causes of this probable death were, but enough D may prevent someone else from being depressed enough to do it. No matter what other problems are in the person's life, being D sufficient may well make the difference between living and dying. It can provide the mental strength needed to cope.
So, I don't really think it's off topic, and I offer this as help for all. I've never felt better, and D is a chief reason why. There is a good reason
why people with a tan give the onlooker the impression that they're healthier; it's because they are
