The immune system protects the body from bacteria, viruses, toxins, and other dangerous pathogens. A body's immune system has the ability to detect pathogens and distinguishes them from the body's normal cells and tissues.

However, before the immune system can protect the body, the immune system must be healthy. If the immune system begins to break down, then germs can attack the body and this will result in illnesses such as the common flu. Thus, it is imperative that one takes good care of the immune system. Here are the top five immune system boosters.

  1. Drink plenty of water. Drinking six to eight glasses of water daily helps to flush out toxins from the body. As a rough guide, drink, in daily ounces, half the body weight in pounds. That is, if the body weight is 140 pounds, drink 70 ounces of water each day.

    Ideally, drink alkaline water. Drinking alkaline water provides the necessary immune system boost. The alkaline buffers in alkaline water pass into the blood stream to help maintain the pH level the body's immune system needs to protect the body from diseases.

  2. Cleanse the body with lemons. One of the best known homemade body cleanses is the Master Cleanse sometimes referred to as the lemonade diet. With lemons as part of the diet, energy and nutrients are derived in lemonade made with fresh-squeezed lemon juice, purified (non-fluoridated) water, grade-B maple syrup, and cayenne pepper.

    Lemons have antiseptic, antibacterial, anti-aging, anti-fatigue and anti-inflammatory benefits to boost the immune system. Lemons are also extremely beneficial for boosting skin and hair. Daily consumption of lemons can make a colossal difference in boosting the appearance of the skin. It rejuvenates the skin and gives a clear, radiant and glowing complexion. Hence, lemon juice is one of the best known home remedies for acne control and boosting the immune system.

  3. Exercise. There are no two ways about this. Exercise supports the immune system by decreasing stress hormone production. Exercise also helps dieters to lose weight and keep in shape. Pick up 10 ways to lose weight safely and tighten the skin after weight loss.

    Exercise allows immune cells to circulate throughout the body more quickly and kill bacteria and viruses. Maintaining a regular exercise plan helps to boost the immune system but this requires discipline, perseverance and determination. Where this is not possible, hire a personal fitness trainer or get an extreme home fitness workout program.

  4. Increase intake of raw fruits and vegetables. A typical immune-boosting diet will include the following per day: five servings of fruit and vegetables, seeds, cold pressed oils, garlic, rich protein foods and whole grains.

    Top 5 Immune System Boosters

    Vegetables are a rich source of dietary fiber which boosts the immune system. Dietary fiber helps in removing the toxins from the colon, thus cleansing the digestive system. With a cleansed colon, more nutrients can be absorbed from food, and toxins can be effectively flushed out of the colon.
  5. If the above ways don't seem to help, do not be afraid to take health supplements. If the regular food intake is not sufficient, basic supplements such as vitamin A, vitamin B6, vitamin B12, vitamin D, folic acid, magnesium and selenium should be taken to help boost the immune system. Essential oils are also an excellent source of immune-stimulating compounds, particularly fatty fish oils with Omega 3.

    Fresh herbs and whole food remedies are always better, compared to packaged herbs or supplements. However, food is often over-processed or lacks the essential nutrients. Vitamin and mineral deficiency subjects the body to more diseases, aging, sickness, resulting in a weakened immune system. With supplements, the immune system can be strengthened.
