Students are no strangers to stress, irregular eating habits, and environmental exposures—factors that can impact gene expression through epigenetic changes.
Epigenetics is the study of how gene expression is regulated by external factors without altering the DNA sequence itself. This process involves changes to gene activity through mechanisms like DNA methylation and histone modification, which control how genes are turned on or off.
While the study of epigenetics is well-known in scientific circles, understanding how campus life influences this process remains critical for students looking to optimize their health.
High academic demands lead to This prolonged stress can alter gene expression, particularly in genes related to the immune system and mental health. Stress hormones like cortisol can trigger epigenetic modifications, making students more susceptible to anxiety, depression, or even long-term health issues.
According to the United Nations Children’s Fund UNICEF, understanding the relationship between academic stress and genetic expression empowers students to seek balance. Incorporating stress-management strategies such as mindfulness, physical activity, and adequate sleep can help reduce the negative effects of stress on gene regulation.
The “university diet” often leans heavily on convenience foods, especially during exam season. Processed foods lacking essential nutrients can disrupt the normal epigenetic mechanisms responsible for healthy gene expression.
Maintaining a balanced diet filled with nutrient-rich foods can have long-term health benefits beyond immediate energy boosts. What you eat today can influence not only your current health but also how your genes are expressed over time.
The post-secondary environment also causes students to have more exposure to substances such as cannabis, alcohol, nicotine, and other illicit drugs. Substance use, such as alcohol, nicotine, and recreational drugs, is another factor that can influence gene expression.
Research has shown excessive alcohol consumption and nicotine use can lead to epigenetic changes that affect genes involved in brain function, mood regulation, and even addiction pathways.
Regular substance use may heighten the risk of developing mental health disorders or substance dependence by altering the way certain genes are expressed.
For students regular or binge drinking, smoking, and drug use can have effects that go beyond short-term consequences, potentially changing genetic regulation in ways that make it harder to maintain long-term health.
Lifestyle changes can positively affect gene expression. Reducing stress, eating a balanced diet, and limiting substance use are all actionable steps that can help regulate genes and promote better long-term health outcomes.
By being mindful of how daily habits and the university environment shape their genetic expression, students can make informed decisions that support both their immediate well-being and future health.
Queen’s offers a host of resources supporting the health and wellness of the University community. These include Athletics & Recreation, mental health and counselling resources, and health services. There are also dedicated courses, such as IDIS 199, The Science of Mental Health, Well-being and Resiliency, that support wellness at Queen’s.
