The Modern Myth of Unbroken Sleep
For decades, we have been told that the gold standard of rest is eight hours of uninterrupted sleep. Waking up in the middle of the night has been framed as a sign of stress, a poor diet, or even a sleep disorder like insomnia. This has created a culture
of sleep anxiety, where any deviation from a solid block of sleep is seen as a failure. However, this obsession with monophasic sleep is a relatively modern invention, largely a product of the industrial revolution and the advent of artificial lighting, which artificially extended the workday and compressed our time for rest.
What Is Segmented Sleep?
Before the industrial age, a different pattern was the norm: segmented sleep. Also known as biphasic sleep, this involves two distinct sleep periods overnight, separated by a stretch of quiet wakefulness. Historically, people would go to bed shortly after dusk for a “first sleep” of about four hours, wake up for an hour or two around midnight, and then have a “second sleep” until morning. This pattern is documented across pre-industrial societies in Europe, Africa, and South Asia. This wakeful period wasn't seen as a problem but as useful time for prayer, quiet reflection, intimacy, or light chores.
Revisiting Traditional Indian Sleep Patterns
While there isn't a single monolithic sleep culture in a country as diverse as India, elements of segmented sleep have long existed. The traditional Ayurvedic system, for instance, acknowledges different sleep patterns and notes that waking during the 'Pitta' time of night (roughly 10 PM to 2 AM) can manifest as a hot, alert state of mind. Furthermore, the concept of waking during the 'Brahma Muhurta'—the auspicious period before sunrise—for meditation and spiritual practices aligns with the idea of a second, more reflective phase of the night. In many parts of India, a post-lunch nap or 'siesta' is also common, suggesting a natural inclination toward biphasic, rather than monophasic, rest.
When Is Waking Up a Real Problem?
It is crucial to distinguish between natural segmented sleep and genuine insomnia. Waking up calmly and falling back asleep with ease is generally normal. The problem arises when nighttime waking is frequent and accompanied by anxiety, racing thoughts, and a persistent inability to return to sleep, a condition known as sleep maintenance insomnia. This can be triggered by stress, an unhealthy diet, medical conditions like sleep apnea, or hormonal imbalances. Modern life in urban India, with its high screen usage and late work hours, has led to a documented sleep crisis, making it harder for many to differentiate between a natural rhythm and a genuine problem.
How to Handle the Wakeful Window
If you find yourself awake in the middle of the night, the key is not to panic. Instead of reaching for your phone—whose blue light can disrupt the sleep-inducing hormone melatonin—try to embrace the quiet. This period can be used for activities that our ancestors practiced: gentle stretching, meditation, reading a physical book under dim light, or simply lying in bed and focusing on your breath. The goal is to keep the environment calm and your mind relaxed. By reframing this time as a bonus period for quietude rather than a frustrating interruption, you can reduce sleep-related anxiety and may find it easier to drift back into your second sleep.
