Endorphin: noun
Definition:
Endorphins are natural neurochemicals produced by the body that act as pain relievers and mood enhancers. They are classified as endogenous opioids, meaning they are naturally synthesized within the body and function similarly to opiates or opioids in terms of pain reduction. Endorphins are primarily produced in the pituitary gland and hypothalamus, which are regions of the brain responsible for regulating various bodily functions and emotions.
These neurotransmitters are released in response to certain stimuli, such as exercise, laughter, or stress, and are known for promoting a sense of well-being and euphoria. They have the ability to mitigate pain by binding to opioid receptors in the brain and spinal cord, hence reducing the perception of pain.
Endorphins are not only involved in pain modulation but also play a role in regulating other bodily functions, including appetite, immune response, and stress levels. Their release can improve mood, decrease stress and anxiety, boost self-esteem, and enhance one's overall sense of happiness and pleasure.
Activities that stimulate endorphin release, such as physical exercise and laughter, are often associated with a "runner's high" or feelings of relaxation and contentment. The importance of endorphins in pain management and emotional well-being has been widely acknowledged and harnessed in therapies for pain control and mental health enhancement.
In conclusion, endorphins are natural opioids manufactured within the body that help alleviate pain, optimize mood, and promote a sense of happiness and well-being.

The word "endorphin" is derived from the combination of two parts: "endo" and "morphine".
- "Endo": This prefix comes from the Greek word "endon", meaning "within" or "inside". It is often used in scientific terminology to indicate something that is internal or originating from within the body.
- "Morphine": Refers to a potent pain-relieving opioid analgesic drug. Morphine is named after Morpheus, the Greek god of dreams, due to its sedative effects.
The term "endorphin" was coined in 1975 by two scientists, John Hughes and Hans Kosterlitz, who were studying the body's natural pain-relief mechanisms. They discovered that certain chemicals, produced by the body internally, acted similarly to morphine by binding to opioid receptors in the brain.
