The human body has a natural way of defending itself against disease and infection. However, sometimes this immune system can fail to prevent certain disease-causing pathogens to enter into the body. Low immunity has been a health concern for the medical community. The ever-changing lifestyle has caused a decrease in the natural disease- fighting ability of the human body and this has made people more prone to developing infections -- both mild and severe.
Step 1
Avoid certain lifestyle habits that could diminish immunity. Some of these habits include consumption of alcohol and smoking.
Step 2
Consume fresh foods, rich in vitamins and minerals. These micronutrients improve immunity naturally. Eat seasonal fruits and vegetables that are fresh and healthy. Also eat foods rich in antioxidants. According to Harvard Health Publications, deficiencies of vitamins A, B-2, B-6, C and E and metals like selenium, iron, folic acid, zinc and copper could alter immunity.
Step 3
Maintain a healthy weight by consuming a healthy, balanced diet and exercising regularly. Shed some weight if you are overweight and obese.
Step 4
Get adequate sleep and maintain regular sleeping hours. A sleep of six to eight hours is necessary to have a healthy immune system.
Step 5
Maintain good personal hygiene and keep your surroundings clean. Wash your hands before you eat and after you have been outdoors. Keeping yourself clean would prevent you from coming in contact with disease-causing pathogens.
Step 6
Consume healthy supplements and herbs. Research has been conducted in this area, according to Harvard Medical School. Some supplements that may prove useful in promoting immunity include aloe vera, garlic, Echinacea and ginseng. Probiotic foods such as yogurt may also be linked to improved immunity.
