If you have ever lain awake with a racing mind, noticed that you fall asleep easily but wake at 3am unable to settle, or felt tired all day but suddenly alert at bedtime, you are not imagining things. These are the signatures of a nervous system that has not received the signal that it is safe to rest.
Sleep requires safety
The sleep-wake cycle is governed in large part by the autonomic nervous system. For the body to initiate and sustain sleep, it needs to shift into parasympathetic dominance — the physiological state associated with rest, repair, and recovery. When the stress response is chronically elevated, this transition is disrupted.
Cortisol, the primary stress hormone, follows a daily rhythm — high in the morning to support waking, dropping through the day, and at its lowest at night. Chronic stress compresses and distorts this rhythm. People find themselves with low cortisol during the day (exhaustion, brain fog) and elevated cortisol at night (wired, unable to wind down).
What yoga therapy addresses
Yoga therapy for sleep works with the root causes directly — not with sedation or distraction, but with practices that actively restore the nervous system's capacity to shift into rest. This includes breathwork to extend the exhale and activate the vagus nerve, restorative postures that signal safety to the body, Yoga Nidra for deep physiological rest, and practices for the evening that begin the transition to sleep earlier in the day.
“The goal is not to make yourself sleep. The goal is to make it safe for sleep to arrive.”
This is something I work with regularly in one-to-one yoga therapy and in group programmes. The practices that support sleep are not complicated, but they do require consistency and a proper sequence. If you are navigating persistent sleep difficulties alongside stress or a health condition, a structured approach is likely to make a meaningful difference.
