Shingles and stress

I got shingles, or the pain started, a day bfore a hurricane hit in S.
Fla. last week and a day after I dd my first three hour spin class,
buring off like 2,000 calories and generally taking my 50-year-old body
about as far physically as it could go, after much training, diet, etc.
Could this be the stresss that triggered the shingles? OR is it long
term cumulative stress or more serious stress, which I have had in my
life, like divorce, job worries, but not recently, thankfully .....
