Endorphins are credited as the cause of the feeling of euphoria and wellbeing found in many forms of exercise, so proponents of this theory believe that the second wind is caused by their early release. [13] Many of these proponents feel that the second wind is very closely related to—or even interchangeable with—the runner's high. [14]
Endorphin production can be triggered by vigorous aerobic exercise. The release of β-endorphin has been postulated to contribute to the phenomenon known as "runner's high". [40] [41] However, several studies have supported the hypothesis that the runner's high is due to the release of endocannabinoids rather than that of endorphins. [42]
β-Endorphin release in response to exercise has been known and studied since at least the 1980s. [21] Studies have demonstrated that serum concentrations of endogenous opioids, in particular β-endorphin and β-lipotropin , increase in response to both acute exercise and training. [ 21 ]

Proponents of dopamine fasting see a benefit from taking periodic breaks from technologies which are seen as addictive, such as smartphones. Dopamine fasting is the general practice of "fasting" or abstaining from any impulsive and behavioral addictions in order to cope with such addictions and thus attempt to reset to a healthier lifestyle.
α-Endorphin (alpha-endorphin) is an endogenous opioid peptide with a length of 16 amino acids, and the amino acid sequence: Tyr-Gly-Gly-Phe-Met-Thr-Ser-Glu-Lys-Ser-Gln-Thr-Pro-Leu-Val-Thr. [1] With the use of mass spectrometry, Nicholas Ling was able to determine the primary sequence of a-endorphin.
It is thought that people with sexual anhedonia have a dysfunction in the release of the chemical dopamine in the nucleus accumbens, the brain's primary reward center.This part of the brain is thought to play a role in pleasurable activities, including laughter, exercise, and music.
Aerobics is a form of physical exercise that combines rhythmic aerobic exercise with stretching and strength training routines with the goal of improving all elements of fitness (flexibility, muscular strength, and cardio-vascular fitness).
