Sleep

Sleep is an essential part of your life. It is not only a form of rest, but a physiological function that helps your body to recharge and perform at its best the next day.
In TCM, sleep is part of the natural rhythm of Yin and Yang in the body. In the concept of Yin-Yang, Yin represents passive forces while Yang represents active forces. TCM classic The Spiritual Axis (Lingshu, 灵枢) uses the Yin-Yang concept to explain sleep in chapter 28. It is said that “when Yang is depleting and Yin is abundant, one’s eyes are closed. When Yin is depleting and Yang is predominant, one is awake.”
Sleep is also believed to be regulated by the cycle of Protective Qi (Wei Qi) and Nutritive Qi (Ying Qi). Protective Qi flows along Yang meridians for 25 rounds during the daytime and circulates through the Yin meridians for another 25 rounds at night. The cycle in the day enables the body to be active and awake, while the cycle at night enables the body to rest and recharge.
Sleep is a part of the Shen activities which function in the day and cease during the night to allow the Heart, Liver, Spleen, Lung and Kidney meridians to rest and recharge. You will be able to sleep well when the Shen is rooted and rested, but your sleep will be affected if the Shen is disturbed.

Insomnia in TCM

Insomnia is a common sleep problem characterised by having trouble falling or staying asleep. In TCM, insomnia can manifest itself as having fitful sleep, difficulty falling asleep, being a light sleeper, being unable to resume sleeping after waking up and having to wake up at a specific time every night.
When one is suffering from insomnia, it is a sign of disharmony in the Heart, Kidney, Spleen, Liver or Gallbladder system or meridians, which are inter-related with one another. Being overworked, having inadequate rest, stress, unhealthy diets, poor lifestyle habits, physical pain or illnesses could disrupt sleep and contribute to insomnia.

What Your Sleep Patterns Tell You About Your Health

In general, a difficulty in falling asleep is usually associated with an excess condition - when heat pathogens build up and disrupt the balance in the Liver or Gallbladder meridians. Waking up easily from sleep and having difficulty falling back to sleep are signs of deficiency in Blood and Qi. Dream-disturbed sleep may be associated with imbalances in the Spleen or Heart meridians.
Observe your sleep pattern and seek your physician’s consultation if your insomnia problem persists for more than two weeks.

What Dreams Tell You About Your Health?

Dreams have been studied for more than 2000 years. According to the TCM classic -- The Spiritual Axis (Lingshu, 灵枢) -- there is an imbalance of Qi when one dreams of:

• Being angry - Qi Excess in the Liver.
• Forests in the mountains – Qi Deficiency in the Liver.
• Having a large meal - Qi Deficiency in the Stomach.
• Open fields - Qi Deficiency in the Large Intestines.
• Weeping, worry, flying or being fearful - Qi Excess in the Lungs.
• Being immersed in water - Qi Deficiency in the Kidneys.

Dreams are generally due to factors such as the Deficiency of Yin and Blood, the accumulation of Heat and Phlegm in the body, and having excess stress or improper eating habits.

Ideal time to sleep

In TCM, Qi flows through 12 principal meridians within the body in a 24-hour cycle. When Qi flows through a specific principal meridian, it takes around 2 hours to vitalise and strengthen the organ system associated to that particular meridian before continuing to subsequent meridians.
The ideal time to sleep in accordance to the meridian clock is from 11pm to 5am. If your sleep is disturbed at a certain hour repeatedly, it is an indication that the paired organ system may require your attention.

Tips to Promote Sleep

• Avoid overeating during dinner. Eating too late, too fast or too much for dinner may cause stagnation of food, which could give rise to sleep discomfort that is accompanied by stomach bloatedness, epigastric distension or acid reflux. Avoid eating food that is difficult to digest during dinner.
  
• Maintain proper work-rest balance. Your body works in accordance with a biological clock that governs your activities and rest. An adequate amount of rest or sleep is crucial to maintaining internal harmony. It enables Jing, Shen and Qi to flow smoothly in your body and helps to recharge and enhance immunity.
  
• Cut down or avoid taking stimulant drinks before sleep. Stimulant drinks, such as coffee, tea, soda, chocolate or other forms of energy drinks should be avoided.
  
• Avoid greasy foods and foods that hinder peristaltic movements in the digestive system. These types of food are difficult to digest and would hence affect sleep quality. Avoid taking greasy foods, beans, corns, onions, bananas, broccoli, yams or potatoes at night for a better sleep.
  
• Limit your fluid intake during the night. This is to avoid disruption of your sleep due to a full bladder.
  
• Exercise regularly. Generally, an appropriate amount of exercise helps to promote Qi and Blood flow in your body. When the flow is smooth, all organ systems perform efficiently and sleep will be enhanced.
  
• Nourish the Heart using Chinese herbs. Insomnia is the manifestation of a Shen disorder. Nourishing the Heart will aid to calm the Shen. Lotus Seed (Lianzi, 莲子), Longan Fruit (Longyan, 龙眼), Biota Seed (Baiziren, 柏子仁), Lily Bulb (Baihe, 百合), Pearl Powder (Zhenzhufen, 珍珠粉), Schizandra Berry (Wuweizi, 五味子), Ganoderma Mushroom (Lingzhi, 灵芝), Jujube Seed (Suanzaoren, 酸枣仁) and Poria (Fuling, 茯苓) are some Chinese herbs that may bring benefits to the Heart.
  
• Go for TCM acupuncture. Acupuncture has long been recognised by the World Health Organisation to be a treatment for insomnia problems. It is effective in directing and regulating Qi movements. Depending on the type of disharmony, TCM physician would select specific acupoints and use stimulating hand techniques to ease insomnia problems. Herbal medication may be incorporated to achieve better results.
  
• Restore energy after staying up late. One may drink American Ginseng or Chrysanthemum tea to help restore energy after staying up late. American Ginseng helps to replenish Qi, supplement body fluids and suppress the body’s internal heat. Chrysanthemum tea helps to reduce internal heat due to a lack of sleep. It has a calming effect and is good for relieving eye ailments.
