In a 2012 study, titled Does the perception that stress affects health matter? The association with health and mortality, researchers from Harvard University looked at the link between the belief that stress is bad for you and public death records. This study tracked 30,000 adults in the US. They concluded that both high amounts of stress and the perception that stress impacts health are each associated with poor health and mental health.
In 1975, Edward Tronick and his team introduced the “Still Face Experiment" at the biennial meeting of the Society for Research in Child Development. They observed a phenomenon where an infant, following three minutes of interaction with a non-responsive and expressionless mother, quickly becomes solemn and cautious. The infant repeatedly tries to restore the usual reciprocal interaction pattern, but when unsuccessful, withdraws. The infant then turns his face and body away from the mother, displaying a withdrawn and hopeless facial expression. This discovery continues to be one of the most widely confirmed findings in the field of developmental psychology.
The exposome is the cumulative measure of an individual's lifetime exposures from environmental and occupational sources and their impact on health. It encompasses interactions between exposures from the environment, diet, lifestyle, etc., and an individual's unique characteristics such as genetics, physiology, and epigenetics.
