8 Tips to promote the immune system against influenza in elderly

Influenza is very common in winter, it usually tends to be uncomplicated, but sometimes it could induce serious complications especially in elderly due to their relatively weak immune system. So we will highlight some important tips that will be helpful in promoting the immune system against influenza in elderly.

1. Receive seasonal influenza vaccine every year in late October: this vaccine stimulates the immune system to produce antibodies which give the full protection against influenza.
2. Follow healthy well-balanced diet: it should consist mainly of proteins as well as vegetables and fruits rich in minerals, vitamins and antioxidants. On the other side, it's recommended to decrease intake of sugar, fat and processed foods.
3. Sleep well: enough hours of good sleep improves brain functions and memory; also it has a direct role in promoting the functional capacity of the immune system.
4. Regular physical exercise: a schedule of 30 minutes for 3 times weekly of physical exercise is very effective in promoting the immune system as it enhances blood circulation and reduces the inflammatory reactions in our bodies. Physical exercise can include aerobics, swimming, biking, running or even walking.
5. Avoid stress: stress increases body levels of cortisol hormone which initiates inflammatory reactions and decrease the functional capacity of the immune system.
6. Vitamin D supplementation: as we age, the immune system becomes weaker. So vitamin D supplementation is helpful in promoting the functional capacity of the immune system.
7. Quit smoking: cigarettes contain harmful substances that cause many damages to the immune system.
8. Maintain your body weight within healthy normal ratios.
