Sweating too much? What is it a sign of?
I sweat a lot. I always have. Even when I was in high school and playing tons of sports and hadn't yet adapted any sort of bad habits like drinking, I was always the sweaty guy. Nobody could attribute this to me being overweight because as a teenager and young adult I was extremely active and good at most sports. As a child I would ride my bike, lord knows how long, just for the sheer hell of it and the hopes of running into a friend or two, not for any exercise reason.
back then I was the sweaty guy and that exists for me to this day. I have tried looking into what could be the cause and had tons of tests done on me as well as attempted several different types of supplements and medications to try to address the issue.
Here is one that is correlation (the two are related) rather than a causation (one causes the other) sort of situation and because it is so inexpensive I will give it a try. IT is just a very common and easily-purchased vitamin that you could probably use more of anyway, so what the hell.

The other day I went at did a mid-day 10k along the lake here and I ran into a friend towards the end of it during my cooldown phase and she asked me "did you jump in the lake? It's freezing!" She is not wrong, the lake is freezing but no, I did not jump in there. That is just how much I generally sweat when I work out. I am a little embarrassed about it but that is the way I have been for a long time and not just when I was overweight.
They say that if you exercise, sweating is a good thing and it is just your body's way of cooling you down. Everyone is different in regards to this because my body might think that few degrees increase is too much while yours might not even notice it.
Of course looking on the internet for why you sweat too much is a great way to make you sweat because there is always some sort of doom and gloom prognosis out there and one that I am looking at right now says that it could be signs of "Leukemia, Malaria, Hyperthyroidism, Lymphoma, and Diabetes." I watch what I eat and exercise regularly so I dont think that is me, or at least I hope not. I like that "neurological condition" is one of the causes as well.
For me, I am willing to try just about anything to deal with this because in summer especially I start to sweat just from being outdoors at all. I don't necessarily need to be exercising to trigger this.
Someone forwarded me an article recently about how in a recent study that in a study that wasn't sponsored by any particular product (a good sign the study is honest) that with 155,000 people studied, that many of the individuals regardless of the sort of cardiovascular shape they were in, had a Vitamin-D deficiency that "may" be a cause.
They don't say definitely because they don't know, and that is one thing I like about unbiased studies.
For me, I was a sweat machine back when my family would go through gallons of milk like water, and we were given milk with our lunch at school whether we wanted it or not. Milk is rich in vitamin D, so I doubt this is the case but since it costs basically nothing to get a bottle of this stuff, I ordered it anyway.
I seriously doubt it will make any difference at all but hell, it is a vitamin and I don't recall very many studies showing that getting "too much" vitamin of any sort resulting in something bad.

When searching, there is very little risk of getting too much vitamin D and if you really really care you can read this medical abstract that is certain to put most people to sleep in order to see what I am talking about.
Will it do anything? Well, I doubt it. For me, I don't go out and exercise to impress anyone else, so I am ok with dripping all over the ground. What I don't like is that I have to be very careful with the clothes that I decide to wear when I am in public not exercising, so if it can help with that, then I am for it.
I'll let you know how this experiment works out but in the meantime if you see someone dripping on the ground running at Lake Shore Drive, there is a good chance that it is me.
