No single "liquid" makes you happy, but chemicals called neurotransmitters and hormones, like Dopamine, Serotonin, Endorphins, and Oxytocin, are released in the brain to create feelings of pleasure, reward, well-being, and connection, often called the "happy chemicals". These substances, rather than a specific fluid, are responsible for your happy feelings.
Endorphins – the happiness hormones – that are associated with feeling enchantment. Dopamine, which is produced when we feel satisfied, resulting in feeling happy, excited and stimulated. Oxytocin, which is linked to relationships and helps us to build bonds with other human beings.
Brain Chemistry & Your Mood: 4 Hormones That Promote Happiness
Feb 28, 2023. Dopamine and serotonin are molecules that send signals throughout the body; these chemicals affect how we feel. When dopamine is released in our brain, we feel a sense of temporary pleasure. Serotonin, while similar to dopamine, creates a long-lasting feeling of happiness or well-being.
What makes us feel sensations of happiness, closeness, and joy? Brain chemicals! There are four primary chemicals that can drive the positive emotions you feel throughout the day: dopamine, oxytocin, serotonin, and endorphins (sometimes referred to as D.O.S.E.).
Engage in activities that make you happy or feel relaxed. This is thought to increase dopamine levels. Some examples include exercise, meditation, yoga, massage, playing with a pet, walking in nature or reading a book.
Once a man makes a commitment, regardless of its nature, testosterone levels decrease, which then allows oxytocin to effectively connect with vasopressin. This connection is crucial for men to bond deeply with their partners, fostering emotional closeness and long-term attachment.
Research has shown that oxytocin levels increase naturally with pleasurable activities, for example:
Foods known to increase dopamine include chicken, almonds, apples, avocados, bananas, beets, chocolate, green leafy vegetables, green tea, lima beans, oatmeal, oranges, peas, sesame and pumpkin seeds, tomatoes, turmeric, watermelon and wheat germ. Engage in activities that make you happy or feel relaxed.
These serotonin-boosting ingredients and their food sources will help better control your mood, stress, sleep and hunger: Tryptophan: Chicken, turkey, fish, beef, pork, nuts, seeds, tofu, cheese, eggs, oats, beans, lentils, spinach, dates, bananas and dark chocolate (70-85% cocoa)
About 75% of your brain is water, making hydration crucial for cognitive functions like memory, focus, and reaction time, as even mild dehydration can impair these abilities; the rest is primarily fat and other tissues, with water essential for creating hormones and neurotransmitters.
Dopamine levels are most depleted by chronic stress, poor sleep, lack of protein/nutrients, obesity, and excessive sugar/saturated fats, which desensitize receptors and impair production; substance misuse (like cocaine) and certain health conditions (like Parkinson's) also directly damage dopamine systems, reducing its availability. Unhealthy lifestyle habits, especially those involving processed foods and lack of sleep, significantly deplete this crucial neurotransmitter.
90% of our happiness is determined not by our genes or environment, but by our perception of the world.
Sex, shopping, smelling cookies baking in the oven — all these things can trigger dopamine release, or a "dopamine rush." This feel-good neurotransmitter is also involved in reinforcement.
A dopamine imbalance can cause depression symptoms, such as apathy and feelings of hopelessness, while a serotonin imbalance can affect the processing of emotions.
Oxytocin is released in response to pleasant mental experiences. Such a release of oxytocin may, e.g., be induced by seeing, hearing, smelling, or thinking of well known and loved persons, but also by other pleasant situations (Uvnäs-Moberg, 1998; Uvnäs-Moberg et al., 2005).
Lots of things can stimulate dopamine like sex, exercise, the nicotine in cigarettes, and recreational drugs like heroine or cocaine. While sex promotes the natural release of dopamine, drugs can trigger an abundant amount of dopamine. This abundance can lead to that euphoric feeling of pleasure.
Brain hack : The 2 minute rule - Do something for 2 minutes before deciding if you want to continue doing it. Your motivation to do a hard task depends on the dopamine level in your brain. Now the trick is to kick start movement, and then let the brain's natural motivation cycle kick in.
Low dopamine symptoms often involve a lack of motivation, pleasure (anhedonia), and energy, leading to fatigue, mood changes like depression/anxiety, difficulty concentrating, and a reduced sex drive, alongside physical issues such as sleep problems, muscle stiffness, tremors, and slow movement (like in Parkinson's).
Oxytocin: The Love Hormone
Research Insight: Inhalation of floral essential oils, such as rose and jasmine, has been linked to increased feelings of relaxation and social bonding, potentially through the stimulation of oxytocin release.
Consistent with these data, we found that lower fasting oxytocin levels were correlated with increased severity of anxiety and depressive symptoms, as well as worse social emotional functioning in women with restrictive anorexia nervosa [24].
Vitamin C Produces Oxytocin
Another nutrient that helps manage levels of oxytocin is Vitamin C. Vitamin C helps produce oxytocin. Vitamin C can be found in most fruit and vegetables such as peppers, citrus fruits, tomatoes and broccoli.
Simple acts like holding hands, hugging, or cuddling release oxytocin, often called the “love hormone,” which helps build trust and makes us feel connected and content. Even small gestures, like a gentle touch on the arm or a quick kiss, can remind each other of the warmth and affection shared.
Oxytocin is sometimes called the "love hormone" because it's thought to be involved in falling in love, mother-child bonding and sexual arousal in females, as well as lifetime pair-bonding of sexual mates among some species.
When a woman doesn't have an emotional and physical connection with her partner, it can lead to increased stress. This is because she may feel like she is carrying the burden of the relationship alone. Stress can lead to physical and mental health issues like headaches, insomnia, and anxiety.
