How to strengthen the immune system of old people
Population ageing is a rapidly growing global phenomenon. According to United Nations estimates, there are currently more than 703 million people over the age of 65, a figure that is expected to more than double by 2050 to about 1.5 billion. This demographic change will have major health and social implications worldwide, especially regarding the prevention and treatment of age-related diseases and the reduction of the immune capacity of the elderly. In Italy, too, the trend is marked: Istat confirms that the ageing index continues to rise, standing at 193.1 elderly people for every hundred young people, confirming the country as one of the oldest in the European Union.
The impact of this phenomenon, known as immunosenescence, requires attention: the weakening of the immune system is associated with old age, making the over-65s more vulnerable to chronic infections and inflammations. It is therefore crucial to develop more solutions to boost the immune defences of the old people and improve their quality of life. Let’s find out what are the best strategies to support this population group, helping them to stay healthy and independent for longer.
Why do immune defences decline with age?
As we age, our immune system naturally weakens. This phenomenon, known as immunosenescence, is the process by which the immune system’s ability to respond quickly and effectively to infection and inflammation diminishes. As we age, the haematopoietic stem cells of the bone marrow gradually reduce their production capacity and produce fewer white blood cells, key components of the immune system.
This decline is particularly marked in the over-65s, making older people more susceptible to infections, chronic inflammation and even cancer. Low immune defences also lead to a reduction in the effectiveness of vaccines, increasing the need for preventive strategies to strengthen the immune defences at the age of 70 and beyond.
Tips for strengthening the immune system in older people
Is it possible to help the immune system work better and respond more effectively to potential external threats, such as bacteria and viruses? Here are some practical tips.
1. A balanced and nutritious diet
Diet plays a key role in supporting the immune defences of the older population. A varied and balanced diet, including foods rich in vitamins and minerals, is essential for the proper functioning of our body’s defence system. Certain nutrients are essential in this process:
- vitamin C and vitamin E are natural antioxidants that help fight free radicals and protect our body cells;
- zinc and selenium are minerals that play a key role in regulating defences;
- probiotics and prebiotics support gut health, which is intricately linked to the immune response.
2. Regular physical activity
Moderate and regular exercise is an important ally for a healthy immune system. Physical activity has been shown to help improve blood circulation and reduce inflammation, two crucial factors for a good immune response. Older people should try to incorporate activities such as walking, resistance training and stretching to keep their bodies healthy and improve their response to seasonal illnesses.
3. Quality of sleep
A good night’s sleep is essential for a healthy lifestyle: during rest, the body produces cytokines, proteins that help fight infection and inflammation. Older people should therefore try to get at least 7-8 hours of sleep a night, avoid coffee and stimulants in the evening and try to maintain a relaxing routine before going to bed.
4. Supplements for the immune system
Immune defence supplements can be a valuable supplement in these cases. Among the various specific products, Special Immuno from Cor.Con. International stands out for its immune-modulating properties: it is a patented food supplement formulated with a balanced combination of bovine colostrum and essential vitamins to support the immune system. Available in convenient chewable tablets, one tablet per day before the main meal is recommended to optimise absorption.
Bovine colostrum is a key ingredient due to its elevated levels of immunoglobulins (Ig) and growth factors. Its composition is particularly rich and includes carbohydrates, proteins, lipids, amino acids, vitamins and minerals, with a protein fraction important for the body’s defences. Among the proteins are the immunoglobulins IgG (G1 + G2), IgA and IgM, which enhance the colostrum’s defensive activity. Other beneficial components include creatine, creatinine, lactoperoxidase and lactoferrin, valuable molecules for overall immune well-being.
Stress management and psychological support
It is well known that mental wellbeing is intricately linked to physical health, and for older people, maintaining a good mental balance is essential to boost the immune system. Chronic stress can compromise the immune system, so relaxing activities such as meditation, reading, gardening or listening to music can help improve mood and reduce stress levels. Similarly, having the support of family and cultivating social relationships is also a crucial factor: older people who have a support network tend to be calmer and enjoy better health.
Slowing down the ageing of the immune system is possible by adopting a healthy lifestyle, with a nutrient-rich diet, physical activity, quality sleep and, if necessary, with the help of specific supplements. By taking these measures, it is possible to effectively activate the immune defences in the over 65 so that they can face the challenges that age brings with it with greater strength and serenity!
