Oxidative stress occurs when the antioxidants present in some parts of the body cannot cope up with the free radical chain reactions acquired from internal or external sources. The cells hit by these free radical chain reactions may become damaged or deformed.
Psychological stress can create free radicals which may lead to oxidative stress in the brain if antioxidants in the area are inadequate.
A positive mood can reverse the process. Being in the presence of loved ones, reading funny comics, watching funny movies or reading jokes can well reverse the process of free radical formation created by psychological stress.
I found a blog about jokes in the MyBlogLog Community authored by Yasmin. I was working late one night and getting stressed, I read some entries on her blog and had quite a good laugh. I felt some energy getting back to me. Laughter is a positive mood that take your worries or stress away.
