Signs of a weak immune system
A poor immune system?
Research shows that vulnerability to the flu and other
seasonal diseases is more often the consequence of a
weak immune system, explaining why some people can
have the flu almost constantly from early autumn up
until late spring, while others are less often affected. Our
bodies however send out signs when our immune system
is weak and looking out for them can help us take better
care of ourselves and prevent any nasty infections. Here
are some of them:
Common signs of a weak immune system
Excess weight is not only bad for the heart and other organs, it also leads to hormonal
imbalances that can hinder the immune system's fight against infections. Being overweight can
increase your chances of getting infected by new strands of flu as well, as a weak immune
system will have a harder time adapting to fight against the new infection, lacking the antibodies
to combat such new flu strands.
Constant dry nose
As unpleasant as it may sound, a running nose actually helps protect against flu viruses. The
mucus in the nose attracts viruses which are then ejected out of the body along with it. Having a
constantly dry nose will make you more susceptible to getting sick, but you can fight against that
by using a humidifier or a saline solution.
Constantly getting the flu
Usually a grown adult should get the flu 1-3 times each season with each time lasting around 3-4
days. If you're getting sick more often than that, it is a clear sign that your immune system is
weak. One solution to improve your immune system is through the intake of vitamins and
minerals, more specifically vitamin C and A as well as zinc and selenium. Vitamin C is found in
oranges, grapefruit, parsley or paprika and vitamin A is found in carrots, liver, fish or eggs. You
can get your zinc intake from wholewheat bread and cereal as well as sea fruit. Selenium is
commonly found in walnuts, bread, fish, meat and eggs.
You like eating a lot of sweets
Besides being overweight, too much sugar is also bad for your immune system. A study by the
American Journal of Clinical Nutrition shows that 100 grams of sugar taken on a daily basis can
hinder your white cells from fighting against infection for up to 5 hours after eating the high-
Things you should avoid
Besides the above signs of a weak immune system, there are other lifestyle related factors that
can contribute to the problem:
Being under constant stress
According to the American Psychological Association long term stress can weaken the immune
system. It's no wonder you are more likely to get sick during a stressful period of work then!
Stress can also aggravate symptoms if you already have the flu, so remember to relax and take it
Not drinking enough water
The human body needs to be hydrated in order for it to eliminate toxins. While the right quantity
of daily water needed can vary from person to person the most common sign that you are
drinking enough liquids is a pale yellow urine color.
