The industry’s most accurate sleep-wake cycle testing reveals whether hormones are your hidden barrier to restful sleep. This test measures both cortisol and melatonin levels at 4 time points throughout the day – providing a true 24-hour sleep/wake pattern.

Melatonin, a hormone produced by the pineal gland during the dark phase of the light/dark cycle, regulates the sleep/wake cycle and the “biological clock”. However, it is now known also to have free radical scavenging and antioxidant properties and a significant role in stimulating the immune system to protect against the growth of abnormal tissues such as breast and prostate cancers.

Cortisol, a hormone produced by the adrenal glands in response to stress, is also known for its diurnal variation linked to the sleep/wake cycle. It has the opposite pattern to melatonin production in a healthy individual. When the cortisol pattern is disrupted, often as a result of excessive stress, it can cause high nighttime cortisol. This leads to more light exposure at night, lowering levels of melatonin.

The Sleep Balance Profile: Accurate, Affordable, Accessible

Now a simple at home testing option eliminates the need for middle of the night samples. The first morning MT6s represents night time melatonin production. Collecting four dried urine strips at four time points during the day is easy and convenient.
