Relationship Between Gut Microorganisms and Sleep Quality in Animals

This paper investigated the relationship between gut microflora and sleep quality by reviewing a literature on changes in intestinal flora and animal metabolism. When the sleep state is intrinsically or externally disturbed, it can cause related disorders such as sleep deprivation, snoring, sleepwalking, leg twitching, and narcolepsy. The sleep process is a crucial period during which the body conducts metabolism. A decline in sleep quality will affect the normal operation of other organs. This paper focuses on the pathology associated with obstructive apnea-sleep in insomnia and its relationship with the intestinal flora. The intestinal flora contains about 1000 species of bacteria, such as specialized anaerobes of the genera Bacteroides, Eubacterium, Bifidobacterium, Ruminalococcus, and Clostridium. Their metabolic processes and products are involved in the production of hormones and neurotransmitters that regulate sleep. The results showed a decrease in the proportion of Bacteroidetes, as well as a reduction in certain bacteria with prebiotic potential. In contrast, there was an increase in the ratio of Proteobacteria and a decrease in the overall intestinal microflora among patients experiencing symptoms related to insomnia or those diagnosed with clinical insomnia.
