Immune cells can be damaged by unstable oxygen molecules in the body called 'free radicals', which may be generated in dangerously high numbers by poor nutrition, X-rays, alcohol, cigarette smoke and pollutants. Vitamins help strengthen the immune system by neutralising these cell-damaging particles. Exercise also helps to maintain good health by promoting blood circulation and ensuring a plentiful supply of oxygen throughout the body. A balanced diet, rich in vitamins and minerals, provides the building blocks for healthy cells. Deep breathing and fresh air replenish vital oxygen.
Regular exercise boosts oxygen intake and helps build cardiovascular and immune system health.
Vitamin A also helps strengthen immune cells. Engage in moderate exercise for an hour a day to ensure plentiful intake of fresh air. This promotes oxygen exchange between blood and air and speeds metabolism, leading to efficient mobilisation of energy from nutrients. The thymus gland, which is located in the upper part of the chest behind the breastbone, is a nursery for immune system cells that help fight infection. Unfortunately, this organ shrinks in size as we grow older and its effectiveness gradually diminishes.
