O sleep, O gentle sleep,
Nature's soft nurse, how have I frighted thee,
That thou no more wilt weigh my eyelids down

William Shakespeare, Henry IV

A good night's sleep is important to health. During sleep the body is in an anabolic state when energy conservation, tissue repair and growth take over.

One would think testing would measure the amounts of all hormones, endogenous and exogenous. Not so.

Interpretation of hormone testing using saliva, dried blood spot, or serum can be tricky when women are using oral, patch, or other hormonal contraception methods.

The types of hormones in these contraceptives are synthetic, and although they may be close to the molecular structure of our body's own estradiol or progesterone, they are not bioidentical. While bioidentical hormones used as supplements react in the same way as our endogenous hormones to the specific antibodies used during hormone testing, non-bioidentical hormones aren’t recognized by these antibodies so they are not measured by the same test.
