Did you know that the immune system which
protects your body from bacteria and viruses will be considerably weaker if you
are under stress?
According to health scientists, when a
person is under stress his body will release a hormone that will prevent his
immune system from destroying bacteria and viruses.
Garvan Institute scientists in Sydney
discovered that a hormone called “neuropeptide Y” (NPY), which prevents the
immune system from destroying bacteria and viruses, is produced when a person
is under stress. It has proven that people are more likely to get sick when
they are too busy or worried.
This is how NPY works: when a person is
under stress, his nerve system will relase a lot of NPY into the bloodstream;
this eventually prevents the immune system from destroying bacteria and viruses.
On the other hands, when the body is relaxed and calm, the immune cells will
act as protection cells to search and destroy bacteria as well as viruses and
thereby increase resistance.
Hopefully, one day this scientific
discovery will lead to finding cures for some illness that are linked to cold,
flu and even cancer and stroke.
I in the meantime, according to health
scientists, the best thing to do to strengthen the immune system is to relax,
stay calm, recognize one’s lifestyle and take up “Yoga” or “Tai Chi”.
