🌙 Did You Know?
Cortisol — often called the body’s primary stress hormone — naturally follows a daily rhythm.
In the morning, cortisol levels are at their highest, helping us wake up and feel alert. Throughout the day, levels gradually decline, and by evening and night they are naturally at their lowest, helping the body prepare for rest and sleep.
So why do some people feel more agitated or sensitive to noises at night?
When cortisol and daytime alertness decrease, the brain’s filtering system also relaxes. In the quiet of the evening, small sounds can seem louder or more significant. With fewer distractions and lower stimulation, the mind may become more aware of subtle noises or sensations, sometimes triggering a mild alert or startle response.
From an evolutionary perspective, humans are also wired to be more vigilant in the dark — a natural protective mechanism.
Understanding these rhythms can help us normalise why the mind sometimes feels more reactive or alert at night, particularly during periods of stress.
✨ Awareness of the body’s natural rhythms is a powerful step toward better sleep and nervous system balance.
