Brain's Safety Key to Sleep, Not Just Routine
3 Aug
Summary
- Brain needs to feel safe to initiate sleep.
- Unresolved stress and anxiety disrupt sleep cycles.
- Gratitude writing improves sleep quality by fostering security.
Sleep hinges on the brain feeling secure enough to switch off, according to cognitive neuroscientist Yousuf Aslam. Persistent stress and anxiety can prevent this transition, keeping the brain in a state of alertness.
Biological systems like circadian rhythms and sleep-wake homeostasis regulate sleep. However, emotional factors play an equally significant role. When the brain perceives a lack of safety, due to past memories or future worries, it triggers the sympathetic nervous response, commonly known as fight or flight.
To combat this, Aslam suggests a nightly gratitude exercise. This involves noting down three things to be grateful for from the day, three for tomorrow, and four about oneself in the present. This practice aims to instill feelings of security and gratitude before sleep.
Writing this list by hand before bed and reviewing it in the morning, within 45 minutes of waking, can help reprogram the brain. This contrasts with the common habit of immediately checking digital devices, which can induce stress. Improving sleep quality can lead to enhanced focus, clarity, and memory.
