Hormones and health
Where does the Endocrine System fit in to this theme of aging and      healing? Consisting of several glands that secrete hormones into the      blood to promote the body’s homeostasis (balance), the Endocrine  System     is all about hormones that stimulate growth and development,  promote     water retention, raise or lower blood glucose and promote  sodium     retention. 
What are the endocrine glands and are they  affected     by my yoga practice? I’ll touch on stress, metabolism,  energy, bodily     fluids, happiness and strength.
Connects, oxygenates, regulates
Pituitary Gland - lying on base of the brain, it’s the master gland as it controls the      release of hormones from other glands. It’s vital to our wellbeing   and    also connects to the Hypothalamus (not an endocrine gland) which     bridges  the Nervous System to the Endocrine System, harmonizing     together. 
Thyroid Gland - in the neck, relates to metabolism (the body’s use of nutrients) for      the entire body’s cells, stimulating the enzymes which deal with the      oxygen and heat in cells and blood vessels/blood pressure. When out   of    balance, iodine (essential trace mineral) is low in the diet,  and  also    causes metabolic rate to slow down—causing weight gain,  fatigue,     weakened immune system, anxiety and depression. Its  other  function is    to increase calcium deposit into the bones. Iodine-rich  foods  include   sea vegetables, cranberries, yogurt,  beans,  strawberries,  potatoes,   cheese. (My yoga stabilizes my  thyroid as my  metabolism is  high, immune   system is good since I  haven’t been sick  in years, and it  keeps anxiety   in check—which I  notice most if I  don’t go).
Pancreas - lies beneath the stomach in the abdomen and handles digestive      functions. Produces insulin, a hormone needed to regulate the amount of      sugar in blood. During digestion, glucose moves in the bloodstream,    the   pancreas releases insulin, and then the body has energy. If the    blood   glucose level is low, the pancreas triggers stored glucose    release from   the kidneys into the urine, expelling more water,    resulting in  excessive  thirst. Hypoglycemia occurs when blood sugar    gets too low.  (In 2nd  series several poses put pressure on this and    other organs,  making  proper digestion a mandatory part of a daily    Ashtanga practice. I  drink  more water as needed as a balancing act.) 
Adrenal Gland - lies on kidneys. Complements the sympathetic nervous system (physical      performance “fight or flight” response), regulates mineral balance,      energy balance and sexual characteristics. Electrolytes are   regulated.    Metabolism of proteins and fats are handled. Maintains    anti-inflammatory   properties such as cortisone. 
Ovaries - Daily strenuous yoga practice changes the menstrual cycle while      challenged day after day. This happened to me in the first few months of      practicing Mysore every day. It’s important to pace yourself, and      because the practice continues each day to the same level as the day      before, it’s best to only add on new poses once you’re feeling  really     physically competent, pain free and energetic.
Pineal Gland - secretes melatonin, needed for regulated daytime and nighttime      (sleep). A good night's sleep is imperative to a healthy Ashtanga yoga      practice.
