A third of Americans don't get enough sleep, due to stress or health problems. Sleep disorders are linked to weight gain, high blood sugar, anxiety, and driving & workplace injuries.

Using four saliva samples, the test measures stress hormone (cortisol) and sleep hormone (melatonin) within 24 hours: morning, noon, evening, & night, to assess whether your levels follow the daily natural rhythm.

You can also order a 24 cortisol test (4x)or adrenal stress test.
