Relationship between emotion and health: a two-way street

Abstract

Emotional reactions impact on people's health and quality of life. With the advent of neuroscience in the 1990s, much research has focused on the relationship between neural circuits and emotional reactions. In this sense, we have identified a 2031% growth in research linking emotions and health between 1990 and 2022. Using the Text mining tool called "Biotext Tools", we performed a literature search, focusing on diseases of old age and covid-19. Emotion molecules (EMs), produced by the endocrine system, impact the homeostasis of the body, affecting the biological balance of the body. We related the EMs with diseases of the elderly and Covid-19, in order to analyze the impact of emotional states on the development and treatment of these pathologies. To this end, the bidirectional relationship between anxiety, depression, heart disease, stroke, and Alzheimer's and Parkinson's diseases was analyzed. Finally, Coronavirus severity and mortality levels were related to cortisol, testosterone, and serotonin levels.
