Goal Here:
I aspire for this thread/discussion to flourish, encompassing the entirety of the wide spectrum of natural hormones that our bodies produce, delving into their intricacies such as their production, timing, triggers, subsequent reactions and responses, interconnections, synergies, and counterbalances. I am eager to witness and learn from everyone's contributions and perspectives. - Muay Thai.
NOTES:
Pharmacopeia:: a book describing drugs, chemicals, and medicinal preparations. especially: one issued by an officially recognized authority and serving as a standard. : a collection or stock of drugs
Hormesis: is a term that toxicologists use to describe how our bodies respond to certain substances. It means that at low doses, these substances can be good for us, but at high doses, they can be harmful. For example, a little bit of sunlight is good for us and helps our bodies make Vitamin D, but too much sunlight can give us sunburns and increase the risk of skin cancer. The effects of a substance on our body depend on how much of it we are exposed to, and sometimes a little bit can be helpful while too much can be harmful.
is a term used by toxicologists to refer to a biphasic dose response to an environmental agent characterized by a low-dose stimulation or beneficial effect and a high-dose inhibitory or toxic effect?
When we are involved in a physical fight, our body undergoes a cascade of physiological changes in response to the stress of the situation. Hormesis, which is the principle that a low dose of a stressor can actually be beneficial for our health, may play a role in the body's response to a physical fight. However, the primary driver of the body's response is the sympathetic nervous system, which is activated in response to stress.
The sympathetic nervous system releases the hormone norepinephrine (also called noradrenaline), which prepares the body for action. This hormone causes the heart rate and blood pressure to increase, which increases blood flow to the muscles and brain. The increased blood flow delivers more oxygen and nutrients to these tissues, which helps them function more effectively.
At the same time, the sympathetic nervous system triggers the release of glucose from the liver into the bloodstream. This provides the body with a quick source of energy to fuel the fight-or-flight response. In addition, the adrenal glands release the hormone adrenaline (also called epinephrine), which further activates the sympathetic nervous system and increases blood flow and glucose levels.
Other epigenetic responses that occur during a physical fight include the release of cortisol, which helps the body cope with stress by increasing blood sugar levels and suppressing the immune system. This response can be beneficial in the short term but can have negative effects on health if it is chronic.
Vital signs such as heart rate, blood pressure, and respiration rate also increase during a physical fight. These changes are the result of the sympathetic nervous system activation and are a normal part of the body's response to stress.
Overall, the body's response to a physical fight is complex and involves a variety of physiological changes that are designed to help us cope with the stress of the situation. While hormesis may play a role in this response, the primary driver is the sympathetic nervous system and the hormones and other signals it releases.
INTIMACY:
When we engage in physical intimacy such as kissing, hugging, and having sexual intercourse, a cascade of hormonal and neurological responses are triggered in our body. It all begins with the stimulation of nerve endings in the skin, which send signals to the brain's limbic system, the part of the brain responsible for emotions and behavior.
The limbic system activates the release of hormones such as oxytocin, dopamine, and endorphins. Oxytocin is commonly referred to as the "love hormone" as it promotes bonding and intimacy between partners. Dopamine is associated with pleasure and reward and is released in response to pleasurable sensations. Endorphins act as natural painkillers and create feelings of euphoria and relaxation.
During sexual arousal, the body also experiences an increase in heart rate and blood pressure, and glucose levels rise to provide energy for physical activity. The release of electrolytes, bile, and digestive enzymes is also increased to facilitate digestion and absorption of nutrients.
As sexual activity continues, the body experiences a sequence of chemical reactions involving the release of hormones, neurotransmitters, and other signaling molecules. For example, during orgasm, there is a surge of oxytocin and endorphins, creating a sense of intense pleasure and emotional connection between partners.
After sexual activity, the body undergoes a series of physiological changes. Hormone levels return to baseline, heart rate and blood pressure gradually normalize, and glucose levels decrease. Electrolyte and fluid levels are also restored to balance, and the body enters a state of relaxation.
Overall, physical intimacy and sexual activity involve a complex interplay of hormonal and neurological responses that affect various physiological functions in the body.
If anyone can add to this list, that would be great! these are the major ones:
Here is a list of the major natural hormones our body produces, along with a brief description of their functions and interactions:
- Adrenaline: Also known as epinephrine, adrenaline is produced by the adrenal glands in response to stress or danger. It increases heart rate, blood pressure, and respiration, and prepares the body for fight or flight.
- Cortisol: Produced by the adrenal glands, cortisol helps regulate blood sugar, metabolism, and immune response. It is often referred to as the "stress hormone" because it is released in response to stress and can cause negative health effects if chronically elevated.
- Estrogen: Produced mainly by the ovaries in women and in smaller amounts in men, estrogen is responsible for the development of secondary sexual characteristics, regulation of the menstrual cycle, and bone health.
- Progesterone: Produced by the ovaries in women and the testes in men, progesterone helps prepare the body for pregnancy by thickening the uterine lining and suppressing ovulation.
- Testosterone: Produced mainly by the testes in men and the ovaries in women, testosterone is responsible for the development of secondary sexual characteristics in men, including muscle growth and bone density. It also plays a role in regulating sex drive and mood.
- Insulin: Produced by the pancreas, insulin helps regulate blood sugar levels by allowing cells to absorb glucose for energy.
- Glucagon: Also produced by the pancreas, glucagon works in opposition to insulin by raising blood sugar levels when they get too low.
- Growth hormone: Produced by the pituitary gland, growth hormone stimulates growth and cell reproduction in humans and other animals.
- Thyroid hormone: Produced by the thyroid gland, thyroid hormone regulates metabolism, body temperature, and other important bodily functions.
- Melatonin: Produced by the pineal gland, melatonin regulates sleep and wake cycles and is involved in the body's circadian rhythms.
The production and release of these hormones are regulated by a number of factors, including the hypothalamus and pituitary gland in the brain, as well as feedback loops that help maintain balance in the body. Each hormone plays a vital role in maintaining overall health and well-being, and disruptions in their production or regulation can have significant negative effects on the body.
