Cortisol and the 24-hour rhythm

Stress doesn’t stop when the day ends

Cortisol follows a natural 24-hour rhythm, helping regulate stress, energy and alertness. Stress and disrupted sleep can interfere with this rhythm.

Discover our 24h system

Meet cortisol

Cortisol isn't the enemy. It's an essential hormone with a daily job to do. It typically rises around waking, helping you feel alert and ready for the day, before gradually declining towards its lowest levels at night.

It's not about having more or less cortisol.
It's about maintaining the right rhythm.

When the rhythm gets disrupted

Ongoing stress, irregular routines and late nights can disrupt your natural cortisol rhythm, making it harder to switch off when you need to sleep.

This often turns into a cycle.

Poor sleep affects your body's stress response the following day, while ongoing stress can keep cortisol elevated when it should be winding down at night.

Support your rhythm from morning to night

Grounded and Rested are designed to work as a daily system, supporting two different moments of the same 24-hour cycle.

Grounded

Support your body’s natural cortisol response to everyday stress, helping you feel calmer and more balanced throughout the day.

Rested

Support relaxation and your natural transition into sleep, helping your body wind down as cortisol naturally declines towards night.

*Scientific real-life study under medical supervision on 100 participants conducted in the UK in 2025 by an independent research institute.
