Lifestyle Factors

Regular physical activity helps to regulate the gut-brain axis and support overall health. It can promote growth of beneficial bacteria, aiding digestion, enhancing metabolic function, and reducing stress hormone levels.

Mindfulness practices such as meditation can help regulate stress and emotional responses by strengthening neural circuits involved in mood and behavior. These changes can support healthier communication within the gut–brain axis.

Stress and adversity are unavoidable parts of life that can challenge the body’s ability to maintain balance. Prolonged stress can disrupt the gut microbiome and alter signaling within the gut–brain axis, affecting digestion.

Disparities in race, gender, income, and environment shape access to resources and exposure to chronic stress. These inequities can influence stress responses, metabolic regulation, and increase the risk of obesity through changes in the gut–brain axis.

Sleep plays a critical role in maintaining gut microbiome balance and overall physiological function. Disruptions in sleep can alter microbial composition, increase inflammation, and impact metabolic and neural processes.

Exposure to light and darkness helps regulate circadian rhythms, which are essential for maintaining balance in the body. Irregular sleep patterns or excessive artificial light can alter the microbiome’s composition, disrupting digestion, sleep, and behavior.
