Whether dopamine encourages pleasure-seeking activities or hinders logical thinking, the neurotransmitter greatly affects how we behave. One of the most prominent neurotransmitters that impact human behavior is dopamine.
When we experience pleasurable events like eating satisfying food, sexual activity, or drug use, our body releases dopamine. Our brain then associates the release of dopamine with pleasure and creates a reward system. For example, when you eat comforting food, your brain releases dopamine, which makes you feel good. Therefore, your brain assumes this is a reward and encourages you to repeat this behavior, even though the comforting food may not be the healthiest choice for your body.
Dopamine is associated with reinforcement. It is thought to be the chemical that motivates a person to do something repeatedly. Reward and reinforcement help us create our personal habits.
Humans gravitate toward positive experiences and avoid negative ones. Dopamine is what drives us to create these patterns. This is why people with low dopamine levels may be more likely to develop addictions to drugs, food, sex, or alcohol. It is important to note that abnormally low levels of dopamine are not only associated with addiction but can cause physical and mental impairments because this major body chemical controls many body functions.
A release of dopamine is what tells the brain whether an experience was pleasurable enough to experience again. When there is a lack of dopamine, it can cause people to change their behaviors in ways that will help release more of this chemical.
They will pursue activities that trigger their reward center, even if these activities are harmful or taboo. They may seek illicit drugs or alcohol or engage in other harmful, addictive behaviors. An imbalance of dopamine can create an unhealthy reward system response in the brain. Because dopamine is the chemical that drives us to seek positive experiences and avoid negative ones, when this reward system is damaged, human behavior patterns may change to seek out harmful situations and substances as a means of pleasure.
Going from a low dopamine state to a high dopamine state due to the use of illicit drugs is one example of how a person can damage their cognitive function. Though drug use is harmful, the brain only recognizes that it is a source of pleasure and does not seek to stop the behavior. The brain may view many negative experiences as positive ones when its reward system has been damaged. This is true not only with drug use but also in situations such as trauma bonding, where a person stays in a relationship regardless of how harmful or abusive it may be.
Though the reality of the interaction with this person may be damaging, the brain does not recognize it as such. This is a clear example of how powerful brain chemicals can be. Mental health issues may also correspond with a higher risk of addiction. Research suggests that people with mental health conditions may be more likely to abuse mind-altering substances.
There is much debate in the current medical community as to whether addiction is a choice or a disease , and whether low dopamine might be a contributing cause for addiction.
Every individual responds to substances differently. For example, some people become intoxicated very easily, while others can withstand higher amounts of alcohol before getting drunk. Differences like these may be influenced by variations in genetic makeup.
Both tyrosine and phenylalanine are naturally found in protein-rich foods like turkey, beef, eggs, dairy, soy and legumes 8.
Studies show that increasing the amount of tyrosine and phenylalanine in the diet can increase dopamine levels in the brain, which may promote deep thinking and improve memory 7 , 9 , Conversely, when phenylalanine and tyrosine are eliminated from the diet, dopamine levels can become depleted Dopamine is produced from the amino acids tyrosine and phenylalanine, both of which can be obtained from protein-rich foods.
Very high intakes of these amino acids may boost dopamine levels. Some animal research has found that saturated fats , such as those found in animal fat, butter, full-fat dairy, palm oil and coconut oil, may disrupt dopamine signaling in the brain when consumed in very large quantities 12 , 13 , Interestingly, these changes occurred even without differences in weight, body fat, hormones or blood sugar levels.
Some researchers hypothesize that diets high in saturated fat may increase inflammation in the body, leading to changes in the dopamine system, but more research is needed Animal studies have found that diets high in saturated fat can reduce dopamine signaling in the brain, leading to a blunted reward response.
More research is needed. In recent years, scientists have discovered that the gut and brain are closely linked Research in this area is limited. However, several studies show that when consumed in large enough quantities, certain strains of bacteria can reduce symptoms of anxiety and depression in both animals and humans 24 , 25 , Probiotic supplements have been linked to improved mood in humans and animals, but more research is needed to determine the exact role dopamine plays.
Velvet beans, also known as Mucuna pruriens , naturally contain high levels of L-dopa, the precursor molecule to dopamine. Velvet beans are natural sources of L-dopa, a precursor molecule to dopamine. Exercise is recommended for boosting endorphin levels and improving mood.
Improvements in mood can be seen after as little as 10 minutes of aerobic activity but tend to be highest after at least 20 minutes While these effects are probably not entirely due to changes in dopamine levels, animal research suggests that exercise can boost dopamine levels in the brain.
In rats, treadmill running increases the release of dopamine and upregulates the number of dopamine receptors in the reward areas of the brains In one study, a minute session of moderate-intensity treadmill running did not produce an increase in dopamine levels in adults However, one three-month study found that performing one hour of yoga six days per week significantly increased dopamine levels More research is needed to determine the intensity, type and duration of exercise that is most effective at boosting dopamine in humans, but the current research is very promising.
Exercise can improve mood and may boost dopamine levels when performed regularly. More research is needed to determine specific recommendations for increasing dopamine levels. When people are forced to stay awake through the night, the availability of dopamine receptors in the brain is dramatically reduced by the next morning Since dopamine promotes wakefulness, reducing the sensitivity of the receptors should make it easier to fall asleep, especially after a night of insomnia.
However, having less dopamine typically comes with other unpleasant consequences like reduced concentration and poor coordination 37 , Getting regular, high-quality sleep may help keep your dopamine levels balanced and help you feel more alert and high-functioning during the day The National Sleep Foundation recommends 7—9 hours of sleep every night for optimal health for adults, along with proper sleep hygiene It might also intensify your desire for double chocolate chip cookies.
Now you want them even more. It works with other neurotransmitters and hormones, such as serotonin and adrenaline. The right amount of dopamine usually goes along with a pretty good mood. Lack of dopamine can make you sleepy — but not sleeping may also lower your dopamine. One small study in suggests that sleep deprivation can lead to a noticeable reduction in the availability of dopamine receptors in the morning. Very high levels of dopamine can make you feel on top of the world, at least for a while.
It can also put you into serious overdrive. Nicotine , alcohol , or other drugs with addictive qualities activate the dopamine cycle. As a habit forms, the brain responds by toning down the dopamine. Now you need more of the substance to get to that same pleasure level.
Overactivation also affects dopamine receptors in a way that makes you lose interest in other things. That can make you act more compulsively. When it becomes more of a need than a want, this is addiction. If you try to stop, you might go through physical and emotional symptoms of withdrawal. Other things, like genetics and environmental factors, play a role.

Dopamine rewards you whenever you engage in a beneficial behavior and motivates you to repeat the behavior. Every time we do something enjoyable, like eating a nice meal, having sex, or going for a run, a little bit of dopamine is released in our brain.
However, engaging in vices like alcohol or recreational drugs also causes dopamine to be released into the brain. This is why the chemical messenger has been closely linked to addiction. Low dopamine levels can make you feel less motivated, apathetic, listless and affect your ability to concentrate. Some symptoms of low dopamine levels include:. Most of the dopamine produced by your body is made in the midbrain after which it is distributed to different areas in your brain.
Despite decades of research, scientists are still baffled by the exact mechanism of dopamine in the brain. There are four major pathways for dopamine in your brain. Each one controls a different process in your body. Three of these pathways are your rewards pathways and their function is to release dopamine into your brain when you engage in a rewarding activity. Many things could cause low dopamine levels. Some of them include:. Treating dopamine loss aims to cause the production of more dopamine, slow down the breakdown of dopamine that is being produced, create more dopamine receptors, and repair existing dopamine receptors so that they can work better.
There are several supplements and medications available for people who have low dopamine levels. Medication is often used in cases where your depleted dopamine levels is caused by a condition such as depression or schizophrenia. However, there are some techniques you could also use to increase your dopamine levels naturally.
Getting an adequate amount of sleep every night is necessary for maintaining our health. Research has linked sleep deprivation to the suppression of some dopamine receptors in your body.
