How it works

What can this test tell me?

When you’re stressed, your body releases the hormone cortisol to help you cope with the stressful situation. This is a healthy and natural response. 

However, we now live in an environment where we’re often under a lot of pressure. If you’re stressed all the time, your cortisol levels stay high. High cortisol levels can cause sugar cravings, weight gain, and sleep problems. Long-term, it can lead to serious conditions like diabetes and heart disease. 
By measuring your cortisol levels, you'll get a clear picture of how you're coping with everyday stress. Based on your results, you'll get personalised advice on how you can start to reduce or manage stress

Example report 
You have high levels of cortisol in the evening, however your other results are in the normal range. Elevated levels of in the cortisol before bedtime are linked to difficulty in getting to sleep, disturbed sleep and tiredness in the mornings. Long term risks include diabetes, weaker bones and poor heart health.

I recommend you take some steps to reduce your stress levels, with a focus on unwinding before bedtime.
