Immunity is a complex system with many parts. From lymph nodes and tonsils to the spleen with bone marrow. These organs create and then store the cells responsible for calculating and destroying dangerous particles. This uninterrupted “machine” requires regular replenishment, which provides products that are beneficial to the immune system. But proper nutrition alone is not enough.
What to do to support the body’s defenses:
- Sleep well for 8 hours, go to bed on time, get up.
- Give up addictions (smoking with alcohol).
- Walk a lot in the fresh air, in the sun.
- Move more and do moderate exercise.
- Minimize stressors in your environment.
- Maintain body weight within normal limits, do not overeat.
- Get hardened – from dousing with water to a contrast shower.
You will have to give up harmful products for good immunity. You can not leave fast food, food with monosodium glutamate, sugar and sweets in the diet. Store sauces, snacks, salty, fried, smoked foods, drinks with caffeine (tea and coffee with energy drinks) are minimized in the diet.
