Our first defence against viral infection is our immune system. When our immune system is weakened, the virus that are present in our nose and throat will start to attack us. That explained why we have runny nose, blocked nose, sore throat and cough.
Unfortunately, even though our immune system is at a normal state, the much stronger flu virus still attacking us.
Flu causes more damage to children and the elderly because their immune systems are weaker. Other than that, diabetics and smokers tend to have weaker immune systems as well.
Those people who have frequent running nose in the morning or at night, suffer from frequent sore throat or cold sores, or easily catch the cold or flu are having weaker immune system.
Since our immune system is the first defence, it's important that we choose a correct immune booster to help us overcome this flu season and make sure our immune system is at its best.
