The Science of Feeling Good

Family members, friends, and even advertisements are constantly giving us new tips to feel good and promote positive feelings. But what actually works? What is the science behind improving subjective well being, and what studies have investigated the most effective strategies in pursuing happiness? Let’s find out.

Science Behind Happiness

The brain mechanisms that underlie the feeling of happiness are vast and complex. However, the fields of cognitive neuroscience and endocrinology place a focal point on the function of neurotransmitters and hormones in our short term and long term happiness. 

Neurotransmitters are chemical messengers that are used for communication between neurons. These messengers can either excite or inhibit adjacent neurons, and different classes of neurotransmitters manifest different outcomes. Said outcomes range from motor functions to emotional expression and act in a matter of milliseconds. 

Hormones on the other hand, are chemical messengers that can travel through the entire body and exhibit a wide array of effects, most importantly playing a role in behavior for the scope of this article. These messengers are released from numerous endocrine glands, and act over a longer period of time, ranging from seconds to hours, and even days. 

Both neurotransmitters and hormones are extremely important in the feeling and expression of pleasure and happiness. Dopamine and serotonin are both neurotransmitters and hormones that have been directly linked to these positive emotions. According to Dariush Dfarhud et al., shifts toward positive moods are directly correlated with levels of dopamine and serotonin release. Additionally, these changes in mood and heightening of emotions are not always as straightforward. 

Epinephrine, or adrenaline, is a hormone known for the initiation of the fight or flight response during threatening situations. Well renowned psychologists Shachter and Singer conducted an experiment to test the effects of epinephrine on arousal and emotional states. In their paradigm, as stated by Kendra Cherry, a participant in the experimental group was injected with epinephrine and prompted to wait for further instructions. While waiting, they were seated next to one of two people: an excited individual or an angry individual. They found that participants injected with epinephrine who were sat next to either individual mimicked their emotions. To clarify, subjects seated next to a euphoric person were more likely to feel happy and those seated next to an angry person were more likely to feel angry. 

As shown by the data presented above, the experience of happiness goes beyond a singular trigger that improves our emotional state. Our emotions are a complex system and numerous hormones and neurotransmitters are involved in achieving happiness. This being said, there are many factors in our lives that we simply cannot control. 

What We Can’t Control

Oftentimes, we find ourselves in ruts that we can’t seem to escape. Even knowing why we’re experiencing these negative emotions and what we’re feeling does not always seem to help. It is important to understand what factors of emotion are out of our control so we can attack our problems from angles that we have power over. 

For example, a link has been drawn between the cultural fit of emotions being experienced and the levels of satisfaction and happiness. Researcher Jozefien De Leersnyder et al. conducted a study on people belonging to three different cultures: Belgians, Koreans, and European Americans. Participants in each sample were given a questionnaire to determine the individual’s pattern of emotions and see how it aligned with the emotions consistent with their own culture. The results showed that emotional fit within key domains of each culture was associated with positive feelings. Psychological well being in Korea was directly correlated with feelings of home life social relatedness. Additionally, in the U.S., feelings of work life autonomy was correlated with promoted happiness, and both home life relatedness and work life autonomy were factors of psychological well being in Belgium. 

Another study conducted by Amir Mehrdadi et al. analyzed the factors affecting the happiness of Iranian individuals between the ages of 15 and 29. By using questionnaires obtaining data related to quality of life and subjective well being, they found that age was associated with levels of happiness. A positive correlation was discovered, indicating that an increase in age may also lead to an increase in levels of happiness. 

The aforementioned studies indicate that there are a number of components of well being  that cannot be changed. Happiness is affected by elements both in and out of our sight, and attempting to control each and every one would be in vain. This, however, does not mean we should not attempt to improve our subjective well being, as there are components of emotion that are well in our control and can be manipulated with effort. 

What We Can Control

The secret to complete happiness may possibly be unattainable, however, improving subjective well being and promoting positive emotions is not. For specific solutions, we've outlined some helpful tips for managing stress and anxiety during the COVID-19 pandemic as well as loneliness during quarantine as our social lives shrink.

More broadly, one factor that correlates to a person’s level of happiness is their emotional intelligence. Emotional intelligence is the ability to grasp and understand the emotions you’re feeling, along with how one adapts to and copes with experiencing different emotional states. Nicolás Sánchez-Álvarez et al. conducted a meta analysis to determine how emotional intelligence plays a role in subjective well being. With the inclusion of 25 different studies, they found that individuals exhibiting higher emotional intelligence reported higher levels of subjective well being. As stated by the authors, this can potentially be attributed to their ability to perceive and manage emotions more efficiently and effectively. 

Additionally, Maya Tamir et al. studied how the emotions we experience and the emotions we desire to experience affect one another. The experimenters used a cross cultural sample of 2,324 participants from 8 different countries. They found a common result across different cultures, being that happier people were often individuals who experienced the emotions they wanted to experience, no matter if they were pleasant or unpleasant. These results show that constant positive emotions may not lead to happiness in the long run. Rather, allowing yourself to feel what you believe you should feel, whether it’s love, anger, etc., can promote overall well being. 

As shown, improving subjective well being and attaining happiness is manageable. Although there are many underlying factors that we cannot control, there are additional components to happiness that can be manipulated and changed in order to realize this goal of advancing our well being. Developing your emotional intelligence and pursuing emotions you feel are right are just two of the many paths that can be utilized in moving towards a happy life. Luckily, these paths are paved in the different modules provided in the LIFE Intelligence app. 

LIFE Intelligence 

By utilizing LIFE Intelligence, achieving your goal of attaining happiness becomes closer and closer in reach. This is done by educating yourself through the available missions at your disposal and tracking your emotions regularly. 

Mission 2.4 is all about developing self awareness. The app divides self awareness into two categories: internal and external. As stated, internal self awareness is how you view and understand yourself and external self awareness is how you understand the ways in which others perceive you. Gaining internal self awareness can lead to better control of your thoughts and emotions. Furthermore, by gaining control of your emotions, emotional intelligence can be enhanced and subjective well being can be improved. 

In addition, LIFE Intelligence utilizes a wheel of emotions, which helps pinpoint and track different moods you are feeling throughout the day. The wheel helps you master your moods by recording what you feel and why you feel that way. This tool allows you to manage your emotions and gain a deeper understanding of why said emotions may arise. Ultimately, by gaining a deeper understanding of your moods and realizing the patterns that trigger certain emotions, handling of moods can be improved and the pursuit of emotions that “feel right”, as stated above, can be realized. 


The pursuit of happiness is a long journey with many alternative routes. However, as shown by the abovementioned studies, bettering your well being is manageable and should not be written off. Through the use of the LIFE Intelligence app, the goal of a happy life can be achieved.
