Social Contagion as a Force for Better Brain Health

While often regarded as a negative phenomenon, the powerful force of social contagion can be harnessed for good. Today, we’re looking at how the way emotions, ideas, and behaviors spread through social networks can be utilized to boost cognitive well-being on a considerable scale. 

Exploring social contagion

Firstly, let’s go a little deeper into what is meant by the term social contagion. 

  • It’s a concept that has been extensively studied in the fields of psychology and sociology.

  • It concerns the spread of habits, emotions, and ideas throughout a network or group of individuals.

  • It refers to information and behaviors passed unconsciously, and as such, can prove highly influential within the wider population.

It’s easy to think of ways in which social contagion can quickly become negative. We’re talking about anything from groups of adolescents mirroring bullying behavior to large crowds dropping any sense of principles and logic in favor of a herd mentality. 

However, what we’re here to discuss is how social contagion can be a positively influential experience, especially when it comes to brain health. 

4 Ways Social Contagion Can Boost Brain Health

It’s all about spreading good habits. Here are 4 key brain-boosting practices that benefit from the spread of social contagion: 

1. Meditation and Mindfulness

Meditation and mindfulness practices have long been associated with improved mental well-being, reduced stress levels, and enhanced focus. Group meditation sessions and the ongoing discussion of the benefits of mindfulness across communities can encourage more people to explore the benefits of such practices.

2. Mental Stimulation

Group learning initiatives beyond traditional schooling, such as book clubs, for example, can help inspire ongoing learning, which is proven to improve cognitive function and neuroplasticity in the long term. 

3. Social Skills

Additionally, positive social interactions within groups go a long way to providing valuable emotional support to individuals. Being part of a supportive group is a cornerstone of optimum brain health. 

4. Healthy Lifestyle

Regular exercise and a diverse diet rich in nutrients, antioxidants, and omega-3 fatty acids are sure to keep the brain in tip-top condition. Social contagion can be leveraged to form a culture of healthy eating and regular movement habits that will help to slow cognitive decline, reduce the risk of neurodegenerative disease, improve memory, and sharpen overall cognitive ability. 


The conclusion? While we need to be aware of the risks and challenges that face our communities via social contagion, by using the influence of family, friends, and social networks to promote positive behaviors, we can be part of a healthier, happier world.
