What is natural immunity?
Immunity is a body’s function that is achieved with the presence of antibodies in the body specific to a disease. Antibodies are produced naturally by the body to destroy toxins. There are two types of immunity.
Active immunity: It is a type of immunity in which the immune system produces antibodies when you are exposed to disease organisms. In this type of immunity if a person is exposed to the same organism again the immune system recognizes the organism and produces antibodies to fight against it. Sometimes a killed or weakened form of the disease organism is introduced in the body in the form of vaccines to induce an immune response against a specific disease organism. It is long-lasting. It is also called natural immunity.
Passive immunity: It is given in the form of antibodies against disease rather than produced by the body itself. It is given in the form of blood products such as immune globulin when immediate protection against a specific disease is required. But, it lasts for a short time.
What weakens your immune system?
Many people do not realize that some activities negatively affect their immune system. One should recognize such factors to protect against the weakening of the immune system. The factors that are responsible for weakening your immune system are:
Stress: People do not realize that stress has a major impact on their immune system. Chronic stress increases cortisol levels in the body which reduces the secretion of good prostaglandins. Good prostaglandins are the hormones that support the normal functioning of the immune system. Chronic stress makes your body susceptible to catch recurrent infections. You can reduce stress by doing yoga and meditation.
A poor diet: Eating a poor diet plays an important role in affecting the functioning of your immune system. Refined sugars and processed foods can weaken your immune system and make you susceptible to catch the infection. A healthy diet includes fruits, green leafy vegetables, whole grains, nuts, and low-fat milk.
Excessive alcohol drinking: Excessive alcohol consumption reduces the function of your immune system. Alcohol impairs the functioning of the lungs and liver and makes you prone to recurrent bacterial and viral infections.
Inadequate sleep: Without proper sleep, your immune system cannot function properly. Poor sleep reduces the number of T-cells that help your body to fight against diseases. People who do not get enough sleep are more prone to catch the infection.
Lack of exercise: Exercise improves the flow of blood and also helps in removing toxins from the body. Improved blood circulation helps in circulating antibodies and white blood cells that help in protecting your body against infections. People who live a sedentary life can catch infection easily as compared to those who do regular exercise.
Medications: People take prescription and non-prescription medications that weaken their immune system. Studies show that certain antibiotics reduce immune function.
Exposure to UV rays: Exposure to harmful UV rays of the sun also reduces the function of the immune system. This is the major cause of skin cancer and cataracts. Exposure to the UV rays affects the cells responsible for triggering the immune system thus increasing the risk of infection.
Smoking: Cigarette smoking produces toxins in the body and weakens the immune system. Even exposure to secondhand smoking can also affect the functioning of your immune system. Therefore, one should quit smoking to boost up the immune system.

What are the signs of a weak immune system?
Your immune system works throughout the day to keep you protected from harmful organisms. It protects your body against infectious diseases and reduces the risk of recurrent infection. If you have a weak immune system, it cannot work properly. A person with a weak immune system can experience the following signs:
Recurrent infections: Recurrent infections such as cold and flu are common in people with a weak immune system. If you frequently suffer from cold and flu symptoms, you will have weak immunity.
Autoimmune diseases: People with a weak immune system often suffer from autoimmune diseases. It happens when your immune system is overactive and starts attacking healthy body cells leading to autoimmune disorders.
Slow growth and development: A weak immune system also delays the growth and development of children. If your child is not growing normally, you should consult with a pediatrician. Children with a weak immune system should eat a well-balanced diet including high proteins, fruits, green leafy vegetables, fats, and carbohydrates.
Skin problems: The skin is the outermost covering of the body and protects against harmful organisms if you experience recurrent skin rashes or dryness of skin, it indicates a weak immune system.
Digestive problems: Healthy digestive system represents the overall health of your body. There are some useful microorganisms in the gut system that protects against infections and also supports the normal functioning of your immune system. But, if you experience frequent digestive problems such as diarrhea, constipation, bloating, etc, it may indicate a weakened immunity.
High-stress levels: Stress is a response to an unwanted situation. If you remain under frequent stress, it will start affecting the normal functioning of your immune system. This makes your body susceptible to infections.
Slow healing of injuries: If your injury takes a longer time than normal to heal, it means you have a weak immune system. A healthy immune system helps to recover quickly and fight against harmful germs.
Fatigue: If you feel tired when you wake up in the morning and do not feel like doing anything the whole day, it is an indication that your immune system is weak. When your immune system does not work optimally, your body functions start deteriorating and results in fatigue and weakness.
