its indeed a very interesting subject on how to "Improve" Body immunization.
Let me share some interesting facts with you. IF today we are talking about the "IMMUNE SYSTEM" then it is something that a doctor can't even gave u a straight forward answer whther u have a STRONG or a NORMAL immuna system because till now there is no exact measurement to measure it. All the doctors had is only a report from your blood test on your platelets count and such.
To understand the complexity of our Immune System is not that easy because a full immune system can ONLY be at its OPTIMUM stage when ALL 92 organs in our body are FUNCTIONING in "Harmony" & "Synergistically". And that is for LONG-TERM immune system strengthening module.
But if u are looking at only a short-term solution, then all u got to do is only 3 thing as follow:
Before viral attack:
1. Make sure u have sufficient sleep / rest
2. Have a variety of fruits & vege
3. Drink lots of water
BEEN ATTACKED by viral:
1. Sleep and Rest a lot
2. Take more water
3. Take the anti-biotics (to prevent secondary infection)
