Final answer:
Internalizing success and positive experiences can strengthen the immune system. Social support is also beneficial for immune functioning, particularly during times of stress. Chronic stress can weaken the immune system.
Step-by-step explanation:
Researchers found that when people internalize their success and positive experiences, they have stronger immune systems. This means that when individuals attribute their achievements and positive events to their own efforts and abilities, rather than external factors, it positively impacts their immune system. For example, studies have shown that having an internal locus of control, where individuals believe they have control over their own outcomes, is associated with better immune functioning (Benassi, Sweeney, & Durfour, 1988).
Additionally, social support has been found to boost the immune system, particularly in times of stress. Research has shown that individuals who have high levels of social support, such as spouses of cancer patients who report high levels of support, demonstrate better immune functioning compared to those with lower levels of support (Baron, Cutrona, Hicklin, Russell, & Lubaroff, 1990).
It is important to note that chronic stress can weaken the immune system. Numerous studies have shown that various stressors, such as work difficulties, relationship problems, and life events like the death of a spouse, can have negative effects on immune functioning (Glaser & Kiecolt-Glaser, 2005; Segerstrom & Miller, 2004). Therefore, it is crucial to manage stress and cultivate a positive internal mindset for overall immune health.
