Hormones are the body’s chemical messengers and are vital in regulating many mechanisms and pathways within the body.
First, we will identify the hormones associated with mood and pain, and an overview of how these hormones work will be discussed. After this, there is a guide on how you can tell whether you are deficient in them and how to get these hormone levels back up naturally.
How Hormones Work
Hormones are essentially the body’s way of communicating and regulating changes. Hormones are released in response to changes within the body to coordinate different bodily functions.
There have been over 50 different hormones identified in the human body, and these all interact and work together to do many things.
There are two types of glands: Endocrine (which release hormones directly into the bloodstream) and Exocrine (which releases products through a duct system).
Just like a lock and key, when a hormone only binds to its target receptor, the receptor carries out its task, i.e. adrenaline secretions increase adrenaline levels and cause the well-known ‘fight or flight’ response.

Endocrine system
The endocrine system is vital for maintaining homeostasis (regulation) of your bodily systems, such as metabolism, energy and growth, just to name a few.
There have been over 50 endocrine hormones identified in the human body and seven main endocrine glands with which they are associated.
These glands are:
- Pineal
- Hypothalamus
- Pituitary
- Thyroid
- Thymus
- Pancreas
- Adrenal
Additionally, the testes and ovaries are involved in this system.
Furthermore, if you are interested there is a small summary of some of the endocrine system glands, hormones and their actions here.
Exocrine system
The exocrine system is also essential in maintaining homeostasis within the body. However, this system does not release hormones as much as it does excrete substances through ducts throughout the body.
For example, sweat is excreted on the skin to regulate body temperature and digestive enzymes released to aid digestion. The glands involved are located in the stomach, pancreas and intestines.
These glands include:
- Sweat
- Lacrimal
- Salivary
- Mammary
- Digestive
Now, with the basics of hormone systems covered, we will focus on the ‘DOSE’ or ‘happy’ hormones, i.e. the hormones that are involved with and affect mood and emotions.
The DOSE Hormones
These consist of dopamine, oxytocin, serotonin and endorphins, and are part of the endocrine system.
Dopamine
Firstly, this hormone enables motivation, learning and pleasure and plays a role in the accomplishment of goals and desires.

Deficiency in dopamine can present itself in many ways, such as:
- procrastination
- low self-esteem
- low energy
- lack of motivation
- inability to focus
- mood swings
To trigger the release of dopamine, try the following:
- meditation
- create to-do lists
- focus on long term goals
- eat L-Tyrosine rich foods, such as turkey, soy, oats, cottage cheese, pumpkin seeds, and sesame seeds
- exercise regularly
- get creative
Oxytocin
Secondly, this hormone is responsible for feelings of closeness, love and bonding.

As a result, a deficiency in this hormone can manifest in these ways:
- loneliness
- stress and anxiety
- lack of motivation
- low energy
- feeling disconnected from others
- insomnia
To trick your body into releasing oxytocin, try the following:
- physical touch
- socialising
- massage
- acupuncture
- listen to music
Serotonin
Thirdly, this hormone is associated with feeling successful and accomplished, and is related to feeling important and being content with yourself.

Consequently, being deficient in this hormone can present itself in these ways:
- low self-esteem
- being sensitive
- anxiety or panic attacks
- social anxiety
- mood swings
- obsessive or compulsive behaviours
- insomnia
So, to induce serotonin release, try these:
- go outside
- exercise
- massage
- take a cold shower
Endorphins
Finally, endorphins result in a short-term euphoria that helps with pain relief, and relieves feelings of anxiety and depression.

A deficiency in this hormone can result in the following:
- anxiety
- depression
- mood swings
- aches and pains
- insomnia
- impulsive behaviours
To trick your body into releasing more endorphins, try the following:
- laughing
- crying
- getting creative
- eating dark chocolate
- eating spicy food
- exercise or stretches
- massage
- meditation
Additionally, to trigger the release of all of these hormones, you can try the following:
- exercise
- meditation
- cold showers
These will help regulate your emotions, and the cold shower can reset your system.
