Ageing Well – The Immune System

Paper effect bottom

Our immune system, which is made up of special cells, proteins, tissues, and organs, is the body’s defence mechanism against foreign antigens, such as bacteria, parasites, and fungi. All of which can lead to serious infections and then to disease if not kept in check.

In most cases, the immune system does a great job of keeping us healthy and preventing infections. As we age in our younger years, our immune system develops defences against these foreign antigens by acquiring antibodies to the germs we’ve defeated in the past.
-Which is why generally adults tend to get fewer colds than children.

However, as we get older, like most functions of the body, our immune system tends to weaken and a diminished immune function increases the susceptibility to illnesses and can have a profound impact on our general health.

This gradual deterioration of the immune system brought on by natural ageing is referred to as immunosenescence.

No two individuals have the same immune system, like a lot of cases in life’s lottery it comes down to genes. While some people seem to have developed a suit of armour against infections, others get floored whenever there are bugs about.

So a general decline in our immune system may mean the following changes may occur:

Impact of lower immunity on the respiratory system

The deterioration of the immune system is often most keenly felt in the respiratory system.

The lungs and respiratory tract perform the crucial function of breathing essential for life; however, the air that we inhale is not always innocuous as it contains numerous antigens that can be very harmful if they are not eliminated quickly by the immune system. A failure here can lead to inflammatory responses that result in swelling that closes the airways or infection that can lead to severe diseases, such as chronic obstructive pulmonary disease (COPD).

To support our immune system and increase essential nutrient intake, there are diet or supplement choices we can make to boost our general health and lower the risk of contracting certain diseases later in life.

Vitamin A contributes to the function of the immune system- along with the maintenance of mucous membranes in the lungs, helping to build resistance to respiratory diseases and shorten their duration. This makes it a popular supplement for those looking to ward off colds, flu and other infections.

For many years people have acknowledged that taking Vitamin C at the onset of a cold can lessen the symptoms and duration of the cold.

The role of Zinc in support of the immune system is also widely accepted. Maintaining zinc levels can limit the decline in immune function that often occurs with age. It can reduce the length and severity of colds. Individuals with inadequate zinc levels have been shown to be more susceptible to infections and heal slower when wounded.

Selenium lowers oxidative stress in the body which reduces inflammation and enhances immunity.

As we get older, having a strong immune system is crucial to maintaining our general well-being, especially during the months when colds and flu are most common. As we age, we are more vulnerable to infections, so need to take extra precautions to ensure we maintain a healthy immune system and stay healthy for longer.
