Effects of Changes in Water Intake on Mood of High and Low Drinkers (Pross et al, 2014) This study addresses the effects of a change in water intake on mood and physiological sensations in adults. The results showed that a switch toward an increase in water intake has especially beneficial effects on sleep/wake moods of habitual low-volume drinkers. The switch toward a decrease in water intake has detrimental effects on mood rating of habitual high-volume drinkers, including reduced feelings of calmness, satisfaction and positive emotions.
The Role of Exercise in Stress Management(Jackson, 2013) The precise physiological mechanisms by which exercise improves stress are still yet to be defined. Human and animal research reveals that being physically active, improves the manner in which the body handles stress due to changes in hormone responses. It has also been shown that exercise affects neurotransmitters in the brain such as dopamine and serotonin that influence mood and behaviour.
Effects of Alcohol on the Endocrine System (Rachdaoui and Sarkar, 2013) Chronic consumption of a large amount of alcohol disrupts the communication between nervous, endocrine and immune system and causes hormonal disturbances that lead to profound and serious consequences at physiological and behavioural levels.
The Effect of Music on the Production of Neurotransmitters, Hormones, Cytokines, and Peptides: A Review(Gangrade, 2012) Research on the effects of music exposure on the release of biochemical messengers is an expanding field. The importance of understanding the influence of music on messenger production is a means of explaining behavioral reactions through physiological mechanisms. Signaling molecules that prove integral for important regulatory functions include neurotransmitters, hormones, cytokines, and peptides. Thus music elicits responses promoting positive emotions, alleviation of stress, and immune function. Study of the production of the messengers reveals the connection between the mind and the body. The purpose of the review is to provide a closer look into the effectual relationship between music and production of these messengers by providing literature and analysis.
Oxytocin Increases Generosity in Humans (Zak et al, 2007) The researchers invesigated the impact of Oxytocin on generocity. Participants in the study were infused with 40 IU Oxytocin or placebo and were subsequently asked to make a one-off decision on how to split a sum of money with a stranger, that could also be rejected. The researchers found that those given the Oxytocin, were 80% more generous than those given a placebo and in addition, that as a result, the generous participants left the experiment with less money. They concluded that "by increasing Oxytocin, the ability to empathize with others, and the motivation to be generous with them, are enhanced".
Neurotransmitters and Nutrition (Colby-Morley, 1983) “It is thought that certain disease states may result from inadequate release of precursor-dependent neurotransmitters.”
