The immune system of a human body is a network of cells, tissues and organs that work together to defend the body against the attacks by the 'foreign' invaders. The term 'foreign invader' is used for the bacteria, parasites, fungi and other viruses that can lead to illness through infections. It is the job of an immune system to keep these infectious organisms out and destroy them.
Though unseen, the immune system cells are constantly gobbling up with the bacteria and blocking viruses from invading your cells. Similar to your heartbeat and indigestion, the immune response is a system that functions on its own and you don't control them. But, there are a lot of practices that can work as your helping hand. Some of such practices are:
Good hygiene- The first step to begin with the defence is to keep all prospective germs at bay. How can it be done? By following good personal hygiene habits. Stop infection as it begins and before it begins. Make sure you avoid spreading your infections to others with these simple measures:
Wash your hands regularly with soap or use sanitizers 5-6 times a day. Always prepare or eat food after washing your hands and every time you use the restroom.
Whenever you sneeze or cough, make sure you cover your mouth and nose with a tissue in order to avoid its germs infect others.
Always bandage all your cuts because if left open, it can become septic and harm your immune system. If you have any serious cut or wound anywhere on your body, get is examined by the doctor within due course of time.
Do not touch your healing wounds and do not squeeze pimples because doing so allows germs to enter your body.
Wash your hands with soap and water before and after each time you handle a raw food.
Rinse all meat, poultry, and fish under running water before cooking. Rinse all fruits and vegetables under running water before cooking or serving them. Separate raw foods and cooked foods, and never use the same utensils or cutting boards with cooked meat that were used with raw meat.
Healthy travel- If you're planning a trip, make sure you consult your doctor once, for, if your body needs some immunisations and vaccines before you make any travel. Consult your doctor at least 3 months or as early as possible about your journey and ask him about the precautions you have to take during your visit to the place.
