Your diurnal rhythm is a biological rhythm that is synchronized with your day/night cycle and regulated by the hormones cortisol and melatonin. If you experience grogginess in the morning with brain fog continuing into the afternoon, only to find yourself wired at bedtime, it's vital to take a closer look at your cortisol and melatonin levels, and the balance between these two "reverse" hormones. This simple at-home test, will provide a comprehensive snapshot about this important cycle that affects your energy levels and ability to get a restful night's sleep. Most importantly, once you understand this cycle, you can begin to take the steps needed to rebalance, so you can feel energized during the day, and slip into restful sleep at night. Please be sure to collect and return your sample within 14 days of receipt of your lab test. All lab tests expire within 6 months of purchase
