The gut-brain axis describes a complex network of neural, hormonal and immune signalling that links the gastrointestinal system with the central nervous system. Because sleep, digestion and microbial activity all follow circadian rhythms and feedback loops, habits around meals, screen usage, stimulants, alcohol, sleep timing, ambient temperature and stress can influence how effectively this axis functions. In his Instagram post, Dr Saurabh Sethi , a board-certified gastroenterologist, highlights seven common habits that he suggests undermine gut-brain communication. Recent scientific evidence illuminates how each of these behaviours exerts effects on sleep architecture, digestive rhythms and microbial signalling, thereby offering a deeper understanding of how to support the gut-brain ax
