Expert Recommends Morning Water to Regulate Autonomic Nervous System via Gut Health

An imbalanced autonomic nervous system can manifest in a range of uncomfortable symptoms, including insomnia, headaches, fatigue, and digestive issues. While many people instinctively focus on mental relaxation and stress reduction to manage these problems, a leading Japanese expert proposes a different, yet surprisingly effective, approach: targeting the gut.

“

When the autonomic nervous system is out of balance, insomnia, headaches, fatigue, and gastrointestinal discomfort often occur together.

Professor Hiroyuki Kobayashi from Juntendo University's School of Medicine, a renowned authority on autonomic nervous systems, argues that the most efficient entry point for regulation is not the brain, but the intestines. He suggests a simple yet powerful morning ritual: drinking a glass of water immediately upon waking, before consuming any food.

When you think about regulating the autonomic nervous system, people often start by relaxing the brain and reducing stress. However, Professor Hiroyuki Kobayashi... believes that the most efficient entry point is not the brain, but the gut.

This practice is believed to stimulate the intestines, promoting bowel movements and improving overall gut motility. By kickstarting the digestive system, this simple act can help alleviate constipation and enhance gut activity. Consequently, common ailments like headaches and fatigue may also begin to subside.

The connection between the brain and the gut is key. Sudden stomach pain when nervous is a negative example of the brain suppressing the parasympathetic nervous system and worsening gut motility.

The connection between the brain and the gut, often referred to as the 'gut-brain axis,' is central to Kobayashi's theory. He points to instances like sudden stomach pain during stressful situations as evidence of the brain's influence on the gut, where stress can suppress the parasympathetic nervous system and impair intestinal function. Conversely, a healthy gut contributes to emotional well-being, as approximately 95% of serotonin, often called the 'happiness hormone,' is produced in the intestines. A well-functioning gut can therefore lead to a more stable mood and improved emotional state.

About 95% of serotonin, the happiness hormone, is produced in the gut. When the gut is healthy, the autonomic nervous system naturally stabilizes, and mood improves.
