Stress of life + horror movies = physical impact on health

I'm not sure if anybody has raised this kind of issue in the past. Or if this is even an issue at all. Would anybody feel that a individual's physical health can be adversely affected if he/she has a lot of stress in life and is watching horror movies on a regularly basis as well?

This may seem a like a stupid thought to many of you. But does anybody think that work stress complementing horror film viewing can bring on grey hair.  I have been experiencing more work stress over the last 3 months but have been viewing horror for the last 5 months.
