Loneliness
Most studies show that loneliness really affects the health and weakens the immune system. It is believed to be so because people are social beings by nature, and the lack of quality human contact causes certain processes in the brain that stimulate the excess secretion of bad hormones, believed to weaken the immune system.
Canned Food
You probably know that canned food is not the healthiest option, but not many people know that it has harmful effect on the immunity. This comes due to the variety of chemicals contained in canned food that affect the normal function of the immune system.
Antibacterial Soap
An American research showed that children who use antibacterial soap are more prone to allergies. Scientists claim that these soaps actually weaken the immunity.
Insecticides
Any insecticides used to destroy the insects that intrude our homes are harmful to the overall health. Even though they are largely advertised as healthy, meaning they have no side-effects, insecticides actually contain different chemicals that harm the immune system. Interesting is the fact that studies have shown that this is more common in women.
