Serotonin: discover the effects of this hormone in your body and mind

Discover the basic principles of serotonin’s importance by reading the following article. With the help of hypnotherapy we can learn to mentally stimulate the presence of this hormone in our body. Hypnosis can help us get to sleep more easily and to incorporate healthy habits into our daily routine. We may even venture to explore, with the help of hypnotic tools, our sexuality, thus getting to know ourselves better. Our social relations may also become enriched out of this increase of self knowledge. For more information, please contact us or look for your nearest hypnotherapist.

The human brain secretes the hormone serotonin i order to meet different bodily functions. The human brain is an organ of such complexity that inside there are thousands of chemicals interacting so that we can experience things and perceive reality as we do.

Serotonin: 6 effects of this hormone in your body and mind

Some of these substances can only be found in certain types of cells and have very specific functions (and many of them have yet to be discovered), but others act on both the brain and outside of it. This is the case, for example, serotonin, also known as 5-HT.
The 5-HT is deeply integrated into the workings of the human body. Learning by heart all its functions can be very intricate. But here you can see six of the main effects of serotonin has on the human body.

1. It has a key role in digestion

Serotonin is a substance in the brain that acts as a neurotransmitter promoting crossing of information between neurons but beyond the brain it serves many different purposes. In fact, the highest concentrations of serotonin are not in the brain but in the gastrointestinal tract.
It is in the intestin where one of the most important functions of serotonin takes place: the regulation of digestion. Too high levels of serotonin are linked to the onset of diarrhea, whereas an excessive deficit of this substance can cause constipation. It also influences the occurrence (or absence) of appetite.

2. It regulates positive and negative moods

Serotonin can be found in large quantities in many parts of the body, and therefore a general imbalance in the production of this substance can have drastic effects on various factors that affect the way we feel and behave.
Specifically, serotonin has been associated for many years with symptoms of depression, as people with a disorder of this type tend to have low concentrations of 5-HT in the blood. However, it is unknown to what extent is the deficit of serotonin that causes depression or vice versa.

3. It controls the levels of body temperature

Amongst the basic maintenance functions with which we associate serotonin, we can also find thermal regulation. This is a very delicate balance, because a difference of a few degrees can mean body mass mortality of large groups of cellular tissue.
Neurons, for example, are especially sensitive in this regard.

4. Influence on sexual desire

We found a correlation between the levels of serotonin and sexual libido. High levels of 5-HT are associated with a lack of sexual desire, while low levels promote the emergence of behaviours aimed at satisfying this need.
In addition, serotonin also seems to have an effect on humans’ ability to love and feel love for another person. We can read about it in this article (in Spanish):

“La química del amor: una droga muy potente”

5. It reduces levels of aggression

Serotonin also contributes to stabilizing the emotional state of human beings in situations of tension. Specifically, it inhibits aggressive and violent behavior. Thus, the most violent and impulsive people tend to have less serotonin levels activating key areas in the brain than those who are more peaceful.
In addition, this substance does not seem to agree at all with testosterone, a hormone that acts upon neurons by making them insensitive to serotonin, thus promoting aggressive behavior.

6. It regulates the cycle of sleep
Throughout the day, serotonin levels rise and fall describing the curves which mark the circadian rhythm : the schedule that our body follows in order to know when to sleep and when not to. Thus, 5-HT levels tend to reach their peak in the sunniest moments of the day, while in deep sleep they go down to their minimum.
This presents the importance of the production of serotonin in regulating our ability to sleep. Something similar occurs with another substance called melatonin.

Bonus: Discover the excess serotonin syndrome
What happens when the body produces too much serotonin? It is not a trivial question.
The excessive consumption of drugs against depression (so-called “antidepressants”) which are basically responsible for stimulating the production of the hormone serotonin, may have a negative effect on our body. Find out more reading this article (in Spanish):
