Tesla was pretty healthy, as far as I can tell, despite being in abject poverty in his later decades. However, he did suffer several mental episodes in his life, and I think he probably over worked himself and experienced some emotional trauma, which could have been exacerbated by lack of sleep. He was also not overly shy regarding his talents, and despite likely being well above average intelligence and a very hard worker, he probably exaggerated many things. Tesla is forever one of the most interesting people to me. He was truly not a man of his time in many ways and ultimately a tragic figure.
