What is a genetic predisposition?
It’s a pre-existing tendency to be healthy or develop illness, influenced by inherited genes, but it requires external triggers (like smoking or virus exposure) to manifest in health outcomes.

How can genetic influences impact health and illness?
Genes can affect the likelihood of engaging in physical activity, susceptibility to obesity, and the risk for psychological disorders and stress levels, each potentially leading to health outcomes or illnesses.
How do genes affect stress levels?
Genetics influence stress management and stress response, with some people being more predisposed to high stress levels, while others manage stress more effectively.
What are neurotransmitter imbalances?
These occur when neurotransmitter levels (chemicals for neuron communication) become too high or low, affecting physical and mental health. (Due to genetics or stress)
How does serotonin affect physical health?
Increase in serotonin improves sleep, alertness, and digestion, caused by both short intense and long term moderate exercise boosting its levels. (Lin and Kuo 2013)
How are dopamine levels related to mental health?
High dopamine levels are linked to optimism (Mitchell and Phillips 2007), while imbalances in dopamine, serotonin, and other neurotransmitters are connected to schizophrenia symptoms, affecting mood and motivation.
