Reminders of COVID‐19 social distancing can intensify physical pain

Abstract

Social distance regulations have been widely implemented to control the global COVID‐19 pandemic. Individuals have thus been experiencing social pain through social distance regulations. Prior research has shown that social and physical pains share a common neural alarm system. Hence, COVID‐19 social distancing should enhance sensitivity to physical pain. Two laboratory studies were conducted to test the spillover effect of COVID‐19 social distancing on physical pain. The findings supported our hypothesis by showing that participants who were reminded of COVID‐19 social distancing reported a higher level of pain perception in response to immersion in hot water (Experiment 1, N = 102) and expressed a lower pain threshold measured by a pressure algometer than did those of controls (Experiment 2, N = 140). This may be the first experimental evidence demonstrating that people primed with COVID‐19 social distancing have increased sensitivity to physical pain. Our findings suggest that people might be more likely to experience physical pain under the impact of COVID‐19 social distancing. The association between a heightened sense of social disconnection in a global pandemic and increased sensitivity to physical pain should receive more attention.

Causal relationship between COVID-19 and chronic pain: A mendelian randomization study

“…The development of chronic pain in long-COVID may also involve psychological factors. The stress and anxiety brought about by the pandemic, coupled with social isolation during lockdowns, can trigger a physiological response that worsens pain [15,16].…”

“…Although the exact mechanisms of pain in long-COVID remain incompletely understood, they may involve a combination of immune dysregulation, neurosensitivity, and inflammation [14]. Physical and emotional stress, sleep disturbances and reduced physical function may also exacerbate the onset of pain [15,16].…”
