Sleep and the Doshas

Sleep and the Doshas are bound together in Ayurveda, for the tradition holds that the way a person sleeps, and the way sleep fails, both follow from which of the three Doshas is at work, so that Vata, Pitta and Kapha each carry their own pattern of rest and their own pattern of disturbance. Charaka gives sleep, Nidra, a full discussion in the twenty-first chapter of the Sutrasthana, naming it one of the three pillars of health beside food and a balanced life, and the classical texts read it throughout in the language of the Doshas. To understand sleep in this tradition is to understand how the three qualities shape it, at the level of the person’s constitution, at the level of the night’s hours, and at the level of what goes wrong and how it is set right.

The three Doshas in brief

Ayurveda describes the body and mind as governed by three functional qualities. Vata is light, dry, cold, mobile and subtle, the principle of movement and of the nervous system. Pitta is hot, sharp, light and penetrating, the principle of transformation and of digestion. Kapha is heavy, cool, slow, stable and unctuous, the principle of structure and of rest itself. Every person carries all three in a particular balance, their Prakriti or constitution, and it is this balance, together with whichever Dosha has risen out of it, that colours their sleep.

The Dosha clock of the night

The tradition maps the Doshas onto the hours, and this map explains much about sleep. The day and night are each divided into three parts, and each part falls under a Dosha.

• The evening, from roughly sunset, is a Vata time, light and mobile, which is why the transition into sleep is a Vata affair and why the bedtime routine is aimed at settling Vata.
• The deep night, the hours after settling, moves toward Kapha, heavy and stable, and it is Kapha’s steadying quality that holds a person in sound, unbroken sleep.
• The small hours before dawn shift again toward Pitta, sharp and active, which is why a heated Pitta pattern so often wakes a person at that time, and why the tradition favours rising before the Pitta hour gives way to the heavy Kapha of early morning.

This is why the same night is not uniform. Falling asleep, staying asleep and waking each belong to a different Dosha, and a disturbance in any one shows at its own hour.

The three patterns of sleep and its disturbance

The Vata pattern

A person in whom Vata is high, whether by constitution or by aggravation, tends toward light, broken, irregular sleep. Vata’s own nature is mobile and restless, and it carries this into the night: difficulty falling asleep, a mind that races and will not settle, waking easily and often, and sleep that feels thin and unrefreshing. This is the pattern the texts most often mean by Anidra, the loss of sleep, and it is provoked by the very things that provoke Vata, such as overwork, worry, an empty stomach, travel, cold and an irregular life.

The tradition answers a Vata pattern with the opposites of Vata: warmth, oil, weight, sweetness, quiet and above all regularity. Warm sesame oil for the feet and body, Abhyanga and Padabhyanga; warm milk with a little Jatiphala, nutmeg; the grounding herbs Tagara and Ashwagandha; a warm, nourishing, early supper; and firm, steady hours. Shirodhara with warm oil is the classical therapy where the restlessness runs deep.

The Pitta pattern

A person in whom Pitta is high tends to fall asleep well enough but to wake in the small hours, the mind hot, sharp and alert, unable to return to rest. This fits the Pitta hour before dawn, and the pattern often carries a heated, irritable or over-thinking quality. It is provoked by what provokes Pitta: heat, sharp and spiced food late at night, intense mental work, anger and a driven temperament.

The tradition answers a Pitta pattern with cooling and calming measures: coconut or a Pitta-suited oil rather than heating ones; a lightly warmed rather than hot milk; the cooling herbs Jatamansi and Brahmi; a light, unspiced, early supper; a cool, dark, quiet room; and the setting aside of heated or provoking input late at night. Cooling forms of Shirodhara, such as Ksheera Dhara with medicated milk or Takra Dhara with buttermilk, are the classical therapies where heat is the trouble.

The Kapha pattern

Kapha is the Dosha of rest itself, heavy, slow and stable, and a person in whom it predominates usually sleeps readily, deeply and long. Here the trouble is rarely getting to sleep; it is more often heaviness, grogginess and excessive sleep, a mind and body slow to rouse, and a pull toward sleeping by day. Over-sleep, the texts note, is its own imbalance, dulling Agni and the mind and, in excess, weighing on the body.

The tradition answers a Kapha pattern not by adding rest but by lightening: rising early, before the heavy Kapha hour of the morning takes hold; avoiding day-sleep, which the texts single out as Kapha-provoking; a lighter, earlier, less sweet and less heavy supper; movement and activity; and stimulating, lightening measures in place of grounding ones. What settles a Vata night would only deepen a Kapha heaviness, which is exactly why the tradition reads sleep through the Doshas rather than by one rule for all.

Sleep, the mind and Ojas

Beneath the Dosha patterns lie two further ideas the tradition weaves through its account of sleep. The first is the mind, Manas, which is said to move between Sattva, the clear and calm, Rajas, the restless and driven, and Tamas, the heavy and dull. A Vata or Pitta disturbance is often Rajas overtaking Sattva, the agitated mind that will not rest; a Kapha excess leans toward Tamas, the dull heaviness that over-sleeps. Settling sleep therefore means feeding Sattva and quieting both Rajas and Tamas. The second is Ojas, the subtle essence of vitality the texts hold to be the fruit of good digestion and sound rest and the ground of calm and resilience. Sound sleep builds Ojas, and strong Ojas in turn makes sleep easy; broken sleep depletes it, and depleted Ojas makes rest harder still. The two rise and fall together.

Reading your own pattern

Because the three patterns are distinct, the tradition begins by asking which one a person shows, rather than reaching for a single remedy. Trouble falling asleep with a racing mind points to Vata; waking hot in the small hours points to Pitta; heaviness and over-sleep point to Kapha. Many people show a mixture, and the season shifts the balance too, Vata rising in the cold, dry months, Pitta in the heat, Kapha in the damp of late winter and spring. The remedy follows the reading: warm and grounding for Vata, cool and calming for Pitta, light and rousing for Kapha. This matching of the measure to the Dosha, the person and the season is the heart of the Ayurvedic understanding of sleep.

Why sleep is treated as a pillar

It is worth pausing on the weight the tradition gives to sleep, since it explains the care taken over its Dosha patterns. Charaka names sleep one of the three Upastambhas, the sub-pillars that support the body beside food and a disciplined life, and he holds that upon the balance of waking and sleeping rest happiness and sorrow, nourishment and wasting, strength and weakness, clarity and dullness, and life itself. Sleep in due measure is said to nourish the tissues, steady the mind and renew Ojas; sleep in excess or in deficiency is said to disturb them. This is why Ayurveda does not treat sleeplessness, or its opposite, as a small matter to be met with a single draught, but reads each pattern through the Doshas and answers it in kind. To sleep well, in the classical view, is to keep one of the foundations of health in good order.

In summary

Ayurveda reads sleep as a Dosha affair from beginning to end: Vata governs the falling asleep and, aggravated, brings light, broken, restless nights; Kapha governs deep sleep and, in excess, brings heaviness and over-sleep; Pitta governs the small hours and, aggravated, wakes a person hot and alert. Each pattern has its hour, its cause and its answer, and the tradition settles sleep by settling the Dosha at work, feeding Sattva and building Ojas along the way.
