What Are The Body Clock Telling Us?

In Japanese Kampo, humans and nature are seen as a unified whole, emphasising the concept of “harmony between heaven and humanity.” They say: “Humans correspond to the heavens and earth, and align with the sun and moon.” This highlights that our physiological functions and health are closely linked to natural rhythms, such as seasonal changes, weather, geographical environment, and the cycle of day and night. By following these natural patterns, we can maintain physical and mental balance.

What is “The Body Clock”?

The Body Clock divides the day into 12 two-hour periods, each linked to a specific organ. During these periods, the organ reaches its peak activity, making it the ideal time for actions that support its function. By timing daily habits like eating, resting, or exercising to align with this natural cycle, you can improve energy flow, strengthen your body, and promote longevity.

Here’s how to integrate The Body Clock into your day:

3 AM – 5 AM (Lung Meridian): Sleep deeply
This is when the lungs are most active, circulating oxygen and nutrients throughout the body. Deep, restful sleep during this time enhances blood flow, nourishes organs, and boosts energy for the day ahead.

Tip: Ensure you’re asleep by this time to allow your body to fully restore.
 

5 AM – 7 AM (Large Intestine Meridian): Hydrate and detox
During this time, the large intestine is most active, helping the body eliminate waste and detoxify. Starting your day with a glass of warm water can hydrate your body and promote healthy bowel movements, setting the tone for a refreshed and energised day.

Tip: Light stretching or gentle movement can awaken your digestive system and prepare your body for the day.
 

7 AM – 9 AM (Stomach Meridian): Eat breakfast
During this time, the stomach is at its peak, making it the perfect time to eat a nourishing breakfast. The body is ready to efficiently digest and absorb nutrients, fuelling you for the day ahead.

Tip: Choose light, easily digestible foods like porridge, eggs, or toast. Avoid heavy or greasy meals that can strain digestion.
 

9 AM – 11 AM (Spleen Meridian): Stretch and move
This is the optimal time to support digestion and nutrient absorption. Engaging in light physical activity can enhance blood flow, improve energy circulation, and strengthen your muscles. This gentle movement helps your body process nutrients more efficiently.

Tip: Try a simple seated twist or a few minutes of yoga to stimulate digestion and boost energy levels.
 

11 AM – 1 PM (Heart Meridian): Take a short break
This is the heart’s peak activity period, making it an ideal time to take a short break. Relaxing during this window helps restore energy, improve blood circulation, and refresh your mind, setting you up for a more productive afternoon.

Tip: Consider a 10–15 minute power nap or some quiet time to meditate and calm your mind for better focus and overall well-being.
 

1 PM – 3 PM (Small Intestine Meridian): Eat lunch
This is when your small intestine works at its peak, making it the ideal time to refuel your body. Focus on a balanced meal that includes protein, healthy carbs, and fresh vegetables to maximise nutrient absorption.

Tip: Avoid overeating or indulging in heavy, greasy foods to minimise digestive strain. Chewing your food slowly can also aid digestion and help you feel more satisfied.
 

3 PM – 5 PM (Bladder Meridian): Stay hydrated
During the bladder’s peak activity, staying hydrated is crucial. Drinking water at this time helps flush out toxins, supports kidney function, and alleviates strain on your blood vessels. This is also when your mental clarity is at its best, making it a great time for focused work or study.

Tip: Keep a water bottle nearby and sip throughout the afternoon. For added variety, try herbal tea or lemon-infused water to stay refreshed and energised.
 

5 PM – 7 PM (Kidney Meridian): Eat a light dinner
As the kidneys work to store and balance your body’s energy, this is the perfect time to wind down with a light, balanced dinner. Eating too heavily can strain both your kidneys and digestive system, so focus on simple, nutritious meals. 

Tip: Include foods rich in nutrients like leafy greens, lean protein, and whole grains. Avoid salty or processed foods to reduce kidney strain and promote overall wellness.
 

7 PM – 9 PM (Pericardium Meridian): Relax and unwind
This is the time to focus on calming your mind and body. Engage in soothing activities to promote relaxation and support healthy circulation. Avoid intense physical exercise during this period, as your body needs time to recover and prepare for restful sleep.

Tip: Dedicate a quiet space for meditation or pick up a favourite book to help release tension and set the tone for a peaceful evening.
 

9 PM – 11 PM (Triple Burner Meridian): Calm your mind
This is the ideal time to wind down and transition into a state of relaxation. Engage in light, calming activities to ease your mind and body. Avoid overthinking or stimulating tasks to help your energy settle and prepare for a deep, restful sleep.

Tip: Try journaling, gentle stretching, or listening to soothing music to quiet your thoughts and create a peaceful bedtime routine.
 

11 PM – 1 AM (Gallbladder Meridian): Sleep deeply
This is a critical time for your body to restore and replenish energy. Sleeping during this period supports mental clarity, decision-making, and overall vitality for the next day. Missing this window of rest may result in fatigue, reduced focus, and decreased productivity.

Tip: Establish a consistent bedtime routine to ensure you’re asleep by this time. Avoid screens and stimulants before bed to promote deeper, uninterrupted sleep.
 

1 AM – 3 AM (Liver Meridian): Deep sleep
This is the liver’s peak time for detoxification and energy restoration. During deep sleep, your liver works to filter toxins, regulate blood, and replenish your body’s energy reserves. Interruptions during this period can hinder these vital processes, potentially leading to fatigue, irritability, or sluggishness the next day.

Tip: Prioritise a restful sleep environment by keeping your room dark, quiet, and cool. Avoid heavy meals or alcohol before bedtime to support your liver’s detoxification process.
