The immune system of a human body is a network of cells, tissues, and organs that work together to defend the body against attack by “foreign” invaders. The term “foreign invader” is used for bacteria, parasites, fungi, and other viruses that can cause disease through infection. The job of the immune system is to keep these infectious organisms away and destroy them.

Although not seen, the cells of the immune system are constantly eating bacteria and blocking viruses from invading their cells. Like the heartbeat and indigestion, the immune response is a system that works on its own and does not control them. But there are many practices that can work as your helping hand. Some of these practices are:

• Good hygiene- The first step in getting started with defense is keeping all possible germs at bay. How can this be done? Following good personal hygiene habits. Stop the infection as it begins and before it begins. Make sure you avoid passing your infections to others with these simple steps:
• 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 bathroom.
• Whenever you sneeze or cough, be sure to cover your mouth and nose with a tissue to prevent your germs from infecting others.
• Always bandage all your cuts because if left open they can become septic and damage your immune system. If you have any serious cuts or injuries to any part of your body, your doctor will examine you in due course.
• Do not touch the healing wounds and do not squeeze the pimples because doing so allows germs to enter your body.
• Vaccination or immunization Immunization can prevent a number of serious infections. Whereas the vaccine is used to cure a sore arm or a low fever. Vaccination is generally safe and effective in curing such diseases. And when it comes to infections, check with your doctor for vaccination status. Various health care centers and providers provide vaccination services. Usually:
• Children should receive all necessary immunizations and shots when recommended by doctors.
• All adults should make sure their immunizations are up to date.
• Travelers must receive additional vaccinations prior to travel date.
• Food safety- Mark yourself safe from the causes of food poisoning not because they are life-threatening, but can sometimes lead to serious medical conditions. To do this, you have to prepare and store your food safely. Take the necessary precautions to kill germs or to prevent them from entering your immune system:
• Wash your hands with soap and water before and after each handling of 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.
• Separate raw food from cooked food, and never use the same utensils or cutting boards with cooked meat that were used with raw meat.
• Healthy trip If you are planning a trip, be sure to check with your doctor once, in case your body needs some immunizations and vaccinations before taking any trip. Consult your doctor at least 3 months or as soon as possible about your trip and ask him about the precautions you should take during your visit to the place.
