The verse “नक्तं दिवसं च आरोग्यं भवति” (Nakhtam Divasam cha Arogyam Bhabati) from the Atharvaveda (7.116.1) provides profound insights into the Vedic perspective on health, emphasising the natural rhythms of the day and night cycle as integral to maintaining health and well-being. This verse suggests that health, represented by the term “आरोग्यं” (Arogya), is intricately connected to the natural cycles of the environment, specifically day and night. The passage underlines the importance of understanding and aligning with these cycles to achieve optimal health.
Health, or Arogya, is maintained through a balance between activity and rest, with both the day and night serving essential roles in ensuring the well-being of the body, mind, and spirit.
In the modern context, this Vedic perspective aligns with scientific research on circadian rhythms, sleep, and the benefits of balanced activity. The verse teaches us that health is not achieved through isolated actions but through an integrated approach that recognises the natural cycles of life. By respecting these cycles, we can optimise our physical, mental, and spiritual well-being, ensuring long-term health and vitality.
This holistic view of health, as articulated in the Atharvaveda, remains highly relevant today, providing timeless guidance for living in harmony with the natural world and maintaining a balanced and healthy life.
Breaking Down the Verse:
1. नक्तं (Naktham):
• The word naktham translates to “night.” In the Vedic worldview, night is not simply a period of rest but also a time of rejuvenation, where the body and mind enter a phase of repair and renewal. The night represents a time for the withdrawal of sensory stimuli and for rest, which is crucial for the restoration of physical and mental energy.
2. दिवसं (Divasam):
• Divasam refers to “day.” The day, in contrast to night, is a time of activity, action, and external engagement. The balance between day and night, or activity and rest, is central to the Vedic understanding of health. Day is seen as the time to fulfil one’s duties and responsibilities, to exert energy, and to engage in work, learning, and social interactions.
3. आरोग्यं (Arogya):
• The term Arogya is commonly translated as “health” or “freedom from disease.” In the Vedic context, Arogya goes beyond the mere absence of disease and includes a state of physical, mental, and spiritual well-being. It is a holistic concept that encompasses balance, harmony, vitality, and strength within the body and mind.
Thus, the verse “नक्तं दिवसं च आरोग्यं भवति” suggests that the state of health is determined by the proper alignment with the natural rhythms of day and night. Both rest (night) and activity (day) are necessary for maintaining health. This idea reflects an ancient understanding of health that aligns with circadian rhythms, the natural biological processes that govern sleep, wakefulness, and other physiological functions.
Contextual Meaning and Significance:
The Atharvaveda, one of the four Vedas, includes a variety of hymns related to healing, health, and longevity. In this verse, the day and night cycles are presented as fundamental to the preservation of health. This suggests that the practice of good health is not merely about specific actions, foods, or medicines, but also about living in harmony with the environment and the natural order.
1. The Role of Night in Health (नक्तं):
In the Vedic tradition, night is a time of rest and renewal. The verse indicates that health flourishes when the body is allowed to rejuvenate during the night. This aligns with modern scientific findings that emphasise the importance of sleep for health.
• Restorative Sleep: The Vedic understanding of night as a period for restoration is backed by contemporary science. Sleep is essential for the body’s repair mechanisms to function effectively. During deep sleep, the body produces growth hormones, repairs tissues, consolidates memories, and detoxifies through the lymphatic system. Inadequate sleep leads to a host of health problems, including cognitive impairments, weakened immune function, and increased susceptibility to chronic diseases.
• Circadian Rhythms: Modern science recognises the importance of circadian rhythms, which regulate the sleep-wake cycle and various physiological processes. The body’s internal clock aligns with the external cycles of day and night, affecting hormone levels, body temperature, metabolism, and other vital functions. The Vedic focus on the importance of night aligns with this concept, suggesting that neglecting rest disrupts health, leading to imbalances in bodily functions.
• Spiritual Rejuvenation: In the spiritual context, night is a time for meditation and introspection. The mind is calmed during sleep, allowing for spiritual rejuvenation and renewal. The absence of external distractions at night allows individuals to experience inner peace, a necessary component of spiritual health.
2. The Role of Day in Health (दिवसं):
In contrast to the night, the day is a time for action and engagement with the world. The verse highlights the importance of balanced activity during the day for maintaining health. Day is not merely about work, but about engaging in productive, mindful activity that promotes physical and mental well-being.
• Active Engagement: Daytime is when the body expends energy through physical activity. Whether through work, exercise, or social interaction, active engagement during the day contributes to physical vitality. However, it is important that this activity is balanced and does not lead to overexertion. The verse indicates that health thrives when one engages in regular physical activity during the day while also ensuring rest during the night.
• Mental Engagement: Just as physical activity is essential during the day, mental engagement also plays a critical role in maintaining health. Intellectual stimulation, learning, and creativity during the day help keep the mind sharp and prevent mental stagnation. The balance of mental and physical engagement during the day, coupled with restful rejuvenation at night, is the key to overall well-being.
• Harmony with the Sun: The Vedic understanding of health also includes living in harmony with natural cycles, such as the movement of the sun. The day, marked by sunlight, is a time to be active, while the night, marked by darkness, is for rest. Exposure to natural sunlight helps regulate the body’s internal clock and provides essential Vitamin D, which is vital for bone health, immune function, and mood regulation.
3. Holistic Health: A Balance Between Activity and Rest:
The Vedic concept of Arogya (health) is not merely the absence of disease, but a state of balance and harmony. Health is maintained when an individual observes a proper balance between activity (day) and rest (night). This holistic perspective suggests that health is a dynamic equilibrium rather than a static state.
• Physical Balance: The body requires a balance of activity and rest for optimal functioning. Excessive work without rest leads to exhaustion and illness, while excessive rest leads to lethargy and weakness. The Vedic perspective encourages moderation, with both work and rest contributing to health. Regular exercise during the day helps maintain strength and vitality, while adequate sleep at night allows the body to repair and rejuvenate.
• Mental Balance: Mental health is equally dependent on balance. Constant mental activity without relaxation leads to stress, anxiety, and burnout, while mental inactivity can lead to boredom, depression, and cognitive decline. The balance between active engagement during the day and restorative relaxation at night ensures mental clarity and emotional stability.
• Spiritual Balance: From a spiritual standpoint, health is not just physical or mental but also spiritual. The alignment with the cycles of day and night fosters spiritual growth. The practice of meditation and introspection during the night, and purposeful action during the day, helps individuals grow spiritually and connect with their higher selves.
Scientific Support for the Importance of Day and Night Cycles:
Modern research has validated the significance of aligning human activity with the natural cycles of day and night for maintaining health. The importance of sleep, circadian rhythms, and balanced activity has been extensively studied.
• Circadian Rhythms and Health: Research has shown that disruptions in circadian rhythms, such as those caused by shift work or irregular sleep patterns, can lead to a variety of health problems, including cardiovascular disease, obesity, diabetes, and even cancer. The Atharvaveda’s emphasis on aligning with the day-night cycle reflects a deep understanding of the importance of circadian rhythms for maintaining health.
• The Role of Sleep in Physical and Mental Health: Sleep is essential for physical and mental recovery. Studies show that sleep deprivation negatively impacts cognitive function, emotional regulation, and immune response. Regular, uninterrupted sleep during the night, as suggested in the Atharvaveda, is crucial for long-term health.
• Daytime Activity and Its Benefits: On the other hand, regular physical and mental activity during the day has been shown to reduce the risk of chronic diseases, improve mood, enhance cognitive function, and increase life expectancy. Daytime activity, when balanced with proper rest, is fundamental to maintaining vitality and strength.
