What is more, scientists agree that there is no evidence that one can actually make its immune system work better. However, it’s possible to give our natural defences the best possible support to do their best job. And just like we can give our immunity some help, we can also put some obstacles in its way. High saturated fat intake can activate certain signaling pathways that induce inflammation, thus inhibiting immune function. High fat diets may also increase your susceptibility to infection by suppressing your immune system and white blood cell function .

Vitamin D helps against the risk of complications of infection. In COVID-19 it prevents an exaggerated inflammatory response that has been known to cause severe complications and an increased risk of death. Loneliness is found to alter immune system cells in ways that promote inflammation, which increases the risk of serious diseases like cancer, when left untreated.

If you’re feeling lonely, find a new sense of purpose in life by volunteering your time, caregiving, or immersing yourself into a new community activity.

AIDS.HIV, which causes AIDS, is an acquired viral infection that destroys important white blood cells and weakens the immune system. People with HIV/AIDS can become seriously ill with infections that most people can fight off.
Physiological Reasons for a Weak Immune System
While some people are already born with a weak immune system, others acquire the so-called immune deficiency due to diseases or even medication they are required to take. Among them are chemotherapy medications and corticosteroids, which are prescribed to patients with inflammations. Additionally, rodent studies have suggested that high fat diets can cause gut bacteria changes and damage the intestinal lining, potentially increasing infection and disease risk .
Demonstrating whether an herb — or any substance, for that matter — can enhance immunity is, as yet, a highly complicated matter. Scientists don’t know, for example, whether an herb that seems to raise the levels of antibodies in the blood is actually doing anything beneficial for overall immunity. A reduction in immune response to infections has been demonstrated by older people’s response to vaccines. For example, studies of influenza vaccines have shown that for people over age 65, the vaccine is less effective compared to healthy children .
