What is Sleep (Nidra) in Ayurveda?
According to Acharya Charaka Nidra is defined as the state of mind where the mind is not associated with any type of Indriyas.
Nidra is one of the three pillars of health (Trayostambh) along with Aahara (food) and Bhramacharya (controlled and balanced use of energy).
Ayurveda considers sleep as a natural urge which should not be suppressed. As its suppression causes yawning, bodyaches, drowsiness, headache and heaviness of the eyes etc.
Happiness, misery, nourishment, emaciation, strength, weakness, sterility, knowledge, ignorance, life and death – all these occur depending on the proper and improper sleep.
The same sleep if enjoyed will properly brings about happiness and longevity in human beings. Like a proper diet, proper sleep is also essential for the maintenance of the body and health.
Concept of Immunity (Vyadhishamatva) & Ojas
Ojas is responsible for overall health, energy and liveliness. It is both a mental and physical factor.
It is responsible for maintaining Health, Promotion of Health, Fight and Prevention of the disease.
Immunity in Ayurveda is known as vyadhishamatva. The term vyadhishamatva is made by two words Vyadhi + Shamatva — Vyadhi means Disease, and Shamatva means Resistance. It is the capacity of the body to resist the disease.
Immunity in Ayurveda refers to prevention of disease and quick recovery from disease.
Relation Between Sleep and Immunity
- Quality sleep nourishes Ojas, which is the vital essence responsible for immunity.
- Poor and irregular sleep leads to weakening of digestion, causing mental stress and reduced resistance to the diseases.
- Sleep plays an important role in healing and recovery of the body and helps in fighting against infection.
Role of Doshas in Ayurveda
In Ayurveda sleep is mainly governed by the kapha dosha but sleep disorders are caused by the increased vata and kapha doshas.
- Vata imbalance causes disturbance in sleep, causing worry, anxiety and fear.
- Pitta imbalance leads to difficulty in falling asleep, causing irritability and early awakenings.
- Less frequently Kapha may cause excessive sleep and laziness.
Psychological factors such as Rajas and Tamas also have a great impact as High Rajas dosha is due to stress and anxiety.
Effect of Poor Sleep on Health
- Lack of proper sleep makes one's body devoid of ojas, which is basic energy required for proper functioning of the immune system without which no one can fight against infections and diseases.
- In other words, lack of sufficient sleep will weaken agni or digestive fire, ultimately causing digestion related problems like gas formation, constipation etc.
- Poor sleep habits adversely affects the body by causing low immunity, lack of stamina, feeling of tiredness, dark circles around the eyes, dry and wrinkled skin, signs of aging at an early stage and sometimes health problems like diabetes, obesity and hypertension.
Diet and Sleep Connection
- Ayurveda states that Ahara and Nidra are both connected as both are the part of trayopstambha, one of three pillars of health.
- The quality, quantity, amount, and schedule of food consumed directly affects sleep as digestion (Agni) and mind are related.
- Balanced, light and easily digestible dinner eaten 2-3 hours before going to bed results in deep and sound sleep. This is because proper digestion maintains doshas balance especially calming Vata and Pitta which are responsible for mental activity and metabolism.
- On the other hand, improper diet - such as heavy, oily, spicy, or late night meals – disturbs Agni and leads to Ama (toxin) formation which can block bodily channels and disturb sleep. Overeating or very heavy meals can aggravate Kapha, causing excessive sleep or a feeling of heaviness even after rest.
- As per Ayurveda, some foods include good sleep because of the properties they possess, such as milk, ghee and easily digestible food, as they nourish Ojas and calm the nervous system. On the other hand stimulants like caffeine, processed food or very dry or cold food can disturb food patterns.
Thus maintaining a proper diet not only supports digestion but also helps ensure sound sleep, mental clarity and balance in the body.
Lifestyle and Daily Routine (Dincharya)
In Ayurveda the best time to go to bed is between 10pm to 6am. According to the dosha cycle, sleeping by 10PM allows you to sleep during the kapha phase (calm, heavy, sleep-inducing) but if you stay awake till late, pitta increases which results in overthinking, hunger and sleep disturbances.
- In Ayurveda a suitable night-time routine involves having a light and early dinner around 7-8PM with easily digestible foods like khichdi, dal, soups and avoiding spicy, oily and heavy foods that can disrupt digestion and sleep.
- After dinner, it's crucial to reduce stimulation by observing a digital detox at around 8-9 pm - no mobile phones, TV and avoid noisy environment to prevent vata and pitta aggravation.
- As the bedtime approaches, one should focus on calming the mind through relaxation activities such as reading books, meditation, practicing gratitude while avoiding conversations causing stress or mental strain as a relaxed mind is essential for deep and restorative sleep.
- Other practice includes Abhyanga or oil massage especially of the feet and scalp. Applying warm sesame or coconut oil and gently massaging the feet before bed time helps in relaxing the nervous system and balancing the vata dosha in the body.
This simple ritual can improve sleep quality when practiced regularly.
