As people age, their immune systems gradually weaken in a process called immunosenescence. This decline makes older adults more susceptible to infections and illnesses. One key factor is the shrinking of the thymus gland, which produces fewer new T cells. T cells are crucial for identifying and fighting off new pathogens. Additionally, B cells, responsible for producing antibodies, become less effective, reducing the body’s ability to respond to vaccines and new infections. The innate immune system also slows down; cells like macrophages and natural killer cells don’t work efficiently, making it harder to eliminate harmful invaders. These combined changes mean that elderly individuals get sick more easily and take longer to recover. Understanding these shifts is vital for improving healthcare.
Regular exercise can improve immune responses in older adults. And staying current on vaccines can help prevent severe illness, which can negatively impact immune function.
