A saliva test designed to measure the levels of the hormone cortisol, taken four times in a 24-hour period (morning, noon, evening, and nighttime). Recommended with situational stress and fatigue; an indicator of adrenal imbalance.
Canary Club Diurnal Cortisol (Saliva) - 4x
Summary: The Canary Club Diurnal Cortisol Home Saliva Kit tests cortisol levels. Test includes: four samples of cortisol collected through saliva (C1, C2, C3, C4).
Also known by ZRT Lab Product Name: Diurnal Cortisol
Symptoms of Hormone Dysfunction
Changed patterns of cortisol levels have been observed in connection with abnormal ACTH levels, clinical depression, psychological stress, and such physiological stressors as hypoglycemia, illness, fever, trauma, surgery, fear, pain, physical exertion or extremes of temperature.
What does the Canary Club Diurnal Cortisol check?
By collecting four samples of your saliva, this test will reveal the level of cortisol (a hormone excreted from your Adrenal gland) throughout a 24-hour period. The amount of cortisol present in your body undergoes diurnal variation, with the highest levels present in the early morning, and the lowest levels present around midnight, or 3-5 hours after the onset of sleep.
There is also significant individual variation, although a given person tends to have consistent rhythms.
Factors affecting Cortisol levels
- Caffeine may increase cortisol levels.
- Sleep deprivation increases cortisol levels.
- Intense (high VO2 max) or prolonged physical exercise stimulate cortisol release in order to increase gluconeogenesis and maintain blood glucose. Proper nutrition and high-level conditioning can help stabilize cortisol release.
- Val/Val variation of the BDNF gene in men, and the Val/Met variation in women is associated with increased salivary cortisol in a stressful situation.
- Magnesium supplementation decreases serum cortisol levels after aerobic exercise, but not in resistance training.
- Omega 3 fatty acids, in a dose dependent manner, can lower cortisol release influenced by mental stress by suppressing the synthesis of interleukin-1 and 6 and enhance the synthesis of interleukin-2, where the former promote higher CRH release. Omega 6 fatty acids, on the other hand, acts inversely on interleukin synthesis.
- Hypoestrogenism and melatonin supplementation increases cortisol levels in postmenopausal women.
- Burnout is associated with higher cortisol levels.
- Music therapy can reduce cortisol levels in certain situations.
- Massage therapy can reduce cortisol.
- Anticipating laugh, like when just hanging out with a funny friend, where some funny situation is expected, can reduce cortisol levels.
- Subcutaneous adipose tissue regenerates cortisol from cortisone.
- Makeup reduces cortisol levels in a mental stress situation.
- Anorexia nervosa increases cortisol levels.
- Black tea may speed up recovery from a high cortisol condition.
- The serotonin receptor gene 5HTR2C is associated with increased cortisol production in men.
- Soy derived Phosphatidylserine interacts with cortisol but the right dosage is still unclear.
- Vitamin C may slightly blunt cortisol release in response to a mental stressor.
- Oral contraceptives increase cortisol levels in young women which perform whole-body resistance exercise training.
- Commuting increases cortisol levels, related to the length of the trip, the amount of effort involved and the predictability of the trip.
