HERE’S THE BOTTOM LINE…
Needing to be perfect and believing that others demand perfection from you is linked with poorer physical health. People who think a lot about their need to be perfect and are stressed show evidence of immune system dysregulation. Perfectionism may undermine immune system functioning, which could leave people at a higher risk for poorer physical health.
In our last post, we discussed how thinking a lot about needing to be perfect or being hyper-focused on not being perfect can result in poorer mental health. The effects of perfectionism are certainly far-reaching as research has shown that requiring perfection contributes to depression (Smith et al., 2021), anxiety (Burgess & DiBartolo, 2016), and eating disorders (Bardone-Cone et al., 2007). The question that we will tackle this week is: Do the effects of perfectionism extend to our physical health?

The quick and simple answer is yes! Many studies over the last 25 years have shown that perfectionism is related to poorer physical health (Bonvanie et al., 2015; Pritchard et al., 2007; Saboonchi & Lundh, 2003; Sirois & Molnar, 2016). For example, some of our earlier work showed that people who believe that others expect perfection from them experience more physical health symptoms such as headaches, colds, and fatigue compared to those who do not have these beliefs (see Molnar et al., 2006).
However, we have to keep in mind that how perfectionism is related to physical health can differ depending on the type of perfectionism that we are experiencing. For example, findings show that people who believe that others demand perfection from them (researchers call this socially prescribed perfectionism) tend to experience poorer health across the board whereas those who demand perfection from themselves (researchers refer to this as self-oriented perfectionism) tend to have a complicated relationship with health with some experiencing better health, some experiencing no changes in health, and others experiencing poorer health (Molnar et al., 2012).

So we know that perfectionism is linked with our physical health and often leads to poorer health. However, a lingering question is, why is perfectionism related to our health?
One of our more recent studies may have part of the answer. This study included 248 Canadian young adults (52% female; average age = 23 years) who completed questionnaires that measured how often they thought about their need to be perfect and their stress levels. They also provided blood samples so that we could assess how their immune system was functioning; we were specifically interested in what researchers refer to as low-grade inflammation. Inflammation can occur when a pathogen, virus or bacteria enters the body or when we are injured.

Sometimes inflammation can be good for us because it can keep our body balanced and healthy, but if the inflammation persists for a prolonged period of time, it can lead to poorer outcomes. Our results showed that when people consistently think that they need to be perfect and are stressed, they are more likely to experience higher levels of inflammation. In other words, young adults who thought a lot about their need to be perfect and were stressed showed evidence of immune system dysregulation. These findings suggest that perfectionism may undermine immune system functioning, which could put people at higher risk for poorer health.
