Cortisol is often spoken about as something harmful and as the hormone associated with stress, burnout, or feeling overwhelmed. But cortisol is also part of a carefully timed biological rhythm that helps the body wake, think, move, and engage with the day ahead.
In fact, one of the most important moments in the body’s cortisol cycle happens shortly after we wake up. During this time, the brain naturally increases cortisol levels as part of a process that helps mobilise energy, sharpen attention, and prepare the body for activity.
Rather than being a sign that something is wrong, this temporary rise is a normal and essential part of how the brain and body coordinate the transition from sleep into wakefulness.
When we begin to understand these natural rhythms, stress hormones like cortisol start to look less like enemies and more like signals from a system that is constantly working to help us adapt, respond, and function throughout the day.
