The immune system is the body’s main soldier against viruses and other harmful substances that enter the body. It guards the body and makes sure that every cell is working just fine. However, the immune system can be affected by many things. One of these things is weight. Whether you are underweight or obese, your immune system may be negatively affected.
When you are underweight, this means that your body is not getting the nutrients it needs. It also does not receive sufficient amount of calories needed for energy. If you are underweight and you are still doing many physical exercises, this can weaken your immune system. This is because the calories are being used up by the activities you do. When viruses enter your body, the immune system has no energy to fight them anymore. Therefore, you need to make sure that you eat right. This way, the immune system can always have an energy resource when it needs to fight.
When you are overweight, this means that there is a huge amount of fat in your body. The excess fat cells are not necessarily useful. In fact, they can cause harm in different levels. They can affect the immune system directly by producing cytokines. These are hormones that may inflame cells and tissues. The inflammation may cause infection to the area affected if not attended to immediately.
Being obese may also imply having diabetes. When you have an extremely high level of sugar in your blood, your immune system is weakened because the white blood cells are being restricted in terms of movement and function. When sugar is too much, the white blood cells become slower as the blood becomes thicker. It is difficult for the blood to circulate therefore the WBCs cannot kill the viruses at once.
In order to boost your system, you need to keep your body healthy all the time. You need to drink as much water as you can. Water is the safest fluid that you can intake. However, you need to make sure that it is clean before you drink it. Water can help eliminate the toxins that are slowing down the body’s natural reaction to harmful substances. One sign to know if you have good amount of water in your blood is when your urine is almost clear. You should also need to keep away from stress if you want to improve your immune system. Stress can cause a lot of responses from the brain which can include hormonal imbalance. Keep your mind clear as much as possible and learn to relax from time to time.
It is very important to keep the system at its best as it is the body’s greatest soldier against infection and diseases.
