You may have experienced it — that relaxing feeling after a good run. Often referred to as “runner’s high,” the experience is usually attributed to a burst of endorphins released during exercise. But is that truly an endorphin rush you’re feeling, or something else? David Linden, Ph.D., a professor of neuroscience at the Johns Hopkins University School of Medicine, breaks down the phenomenon of runner’s high and other effects running has on the brain.
When you start out on your run, your body goes through a transition: Your breathing may become heavy, and you might notice your pulse quicken as the heart pumps harder to move oxygenated blood to your muscles and brain. As you hit your stride, your body releases hormones called endorphins. Popular culture identifies these as the chemicals behind “runner’s high,” a short-lasting, deeply euphoric state following intense exercise. Surveys have revealed runner’s high to be rather rare, however, with a majority of athletes never experiencing it. “Indeed, many distance runners feel merely drained or even nauseated at the end of a long race, not blissful,” says Linden. And though endorphins help prevent muscles from feeling pain, it is unlikely that endorphins in the blood contribute to a euphoric feeling, or any mood change at all. Research shows that endorphins do not pass the blood-brain barrier. That relaxed post-run feeling may instead be due to endocannabinoids — biochemical substances similar to cannabis but naturally produced by the body. Exercise increases the levels of endocannabinoids in the bloodstream, Linden explains. Unlike endorphins, endocannabinoids can move easily through the cellular barrier separating the bloodstream from the brain, where these mood-improving neuromodulators promote short-term psychoactive effects such as reduced anxiety and feelings of calm.
The mental benefits don’t stop when you finish your run — regular cardiovascular exercise can spark growth of new blood vessels to nourish the brain. Exercise may also produce new brain cells in certain locations through a process called neurogenesis, which may lead to an overall improvement in brain performance and prevent cognitive decline. “Exercise has a dramatic antidepressive effect,” says Linden. “It blunts the brain’s response to physical and emotional stress.” What’s more, the hippocampus — the part of the brain associated with memory and learning — has been found to increase in volume in the brains of regular exercisers. Other mental benefits include:
By making running or jogging (or any aerobic exercise) a regular part of your routine, you stand to earn more than just physical gains over time. “Voluntary exercise is the single best thing one can do to slow the cognitive decline that accompanies normal aging,” says Linden.
Endorphins are responsible for that feeling you get after a great workout, after eating a piece of dark chocolate, or after having a good laugh with a friend. They are the chemicals in your brain that help you cope with pain and feel good overall. But how much do you really know about endorphins? Let's start with the term: endorphins. The name comes from two words: endogenous (which means coming from the body) and morphine (the opiate pain reliever). So it makes sense that endorphins are your body's natural pain reliever. But what are they exactly? Endorphins are a group of peptides that are produced by your pituitary gland and central nervous system and that act on the opiate receptors in your brain. These neurotransmitters (also sometimes thought of as hormones) act to increase feelings of pleasure and well-being and also to reduce pain and discomfort. Have you ever experienced a rush of endorphins? This typically happens in response to a specific event such as eating a certain food, engaging in a form of exercise, engaging in sexual intercourse, facing a stressful situation, or experiencing something physically painful. For example, if you were out jogging in the woods and sprained your ankle, you might experience an increase in endorphins that would help you to limp out of the forest to safety despite your injury.
Or, endorphins might explain why a group of people could lift a heavy vehicle off of an injured pedestrian after a traffic accident when under normal circumstances they could not fathom doing such a thing. Endorphins are helpful and adaptive and nature's way of keeping us away from feelings of pain and moving us toward feelings of pleasure. Without your endorphins, it's likely that the world would seem a lot less colorful and your days would feel longer and like your "joie de vivre" was missing. Endorphins can have many positive effects in terms of your health and well-being. Imagine that you are on a vacation and are bitten by a snake, yet you don't feel any pain. Why would that be? It's the protective effect of a surge of endorphins, allowing you to cope with the stress of the situation. Below is a list of some of the many benefits of endorphins.
As you can see, the benefits of endorphins are numerous. In fact, getting regular exercise such as working out at moderate intensity for 45 minutes three times per week may be a good first option for those living with mild depression. On the other hand, if you do not have enough endorphins, you may experience the following effects:
We also know that stress can impair your ability to create endorphins, such as experiencing abuse early in life. What can you do to increase your natural endorphins? Contrary to what you might think, you don't need to run a marathon to get a runner's high or do something outrageous to boost your endorphins. While it's true that higher intensity workouts will produce more endorphins than lower intensity workouts, there are still lots of different ways you can boost your endorphins without needing to cross the finish line after 26.2 miles. Below is a list of simple options that you can get started with right away. Eat Dark Chocolate Do you like chocolate? You're in luck. Eating just a piece of dark chocolate can help to boost your endorphins. Exercise Moderate intensity exercise can be helpful to boost your endorphins. Try to get in 45 minutes at least three times per week. Sexual Intercourse When you have sexual intercourse, your body also releases endorphins. Not only are you engaging in physical exercise, but you're also creating a social bond with another person. Create or Listen to Music Music isn't just for entertainment; it can improve your well-being and raise your endorphins. Create Art Just as with creating music, creating art can be helpful for raising your endorphins. Dance If you don't wish to go for a run or do a regular workout, simply dancing around your house can also raise your endorphins. Receive Acupuncture There is some evidence that receiving acupuncture can help with raising endorphins. This makes sense if you consider that acupuncture would also stimulate pain receptors. Get In a Good Laugh Do you like to laugh? There's probably a good reason for that. Laughter can also stimulate your endorphins, so make sure to try and get in a good laugh each day. Watch a funny television show or spend time with people who make you break out in laughter. Eat Spicy Food Did you know that eating spicy food can raise your endorphins? This is a good excuse to try out an Indian restaurant or pick a new spicy item off the menu next time you go out to eat. Massage Just like acupuncture, massage can also help to raise your endorphins. This doesn't even have to be a professional massage; you could ask your partner to give you a massage, invest in a massage chair, or use a portable massager to relax tense muscles. Sauna Did you know that sitting in a sauna will also raise your endorphins? You're not just sweating out stress when you sit in a sauna, you're also improving your well-being. Use Aromatherapy Have you ever tried aromatherapy? It can be as simple as using essential oils while cleaning or running a diffuser to add scent to your environment, both of which can help to raise your endorphins. Watch a TV Drama Show If you're not in the mood to laugh, you could also consider watching a TV drama. This has also been shown to increase your endorphins. Engage in meditation Have you tried meditation? Meditation is another easy way to boost your endorphins, and it doesn't cost anything to get started. All you need is 20 minutes and a Youtube video to get started. Do volunteer work When you do volunteer work, you are not only doing good for others but also boosting your endorphins. This is another simple way to improve your feelings of well-being. Spend time with friends Try to avoid isolation if you are feeling like your endorphins are low. Spending time with friends can help to boost your well-being. What is the difference between endorphins and dopamine in your brain? While endorphins are neurotransmitters that help you to cope with pain and stress, dopamine is a mood-boosting neurotransmitter that is released after you reach a goal. In this way, dopamine is involved in the reward circuit in your brain and helps to motivate you toward tasks (in contrast, low dopamine would also be de-motivating). Higher endorphins can actually lead to higher dopamine production; in this way, endorphins and dopamine are not mutually exclusive but are actually connected in the system that promotes action toward rewards and the good feelings that result. In other words, you might feel motivated to participate in a marathon because of your dopamine reward system, which is further reinforced by the endorphins that are released during the actual act of participating in the race. In this way, endorphins are the quicker-acting "feelings" while dopamine is the longer-acting afterglow. What are the different types of endorphins? There are actually 20 different types of endorphins that have been identified. However, the type of endorphins that have been the subject of the most research are known as "beta-endorphins." These are the endorphins that contribute to well-being and pain relief and that have a similar effect to the pain drug morphine. Without these beta-endorphins, you would be less able to cope with stress and pain. What about the difference between endorphins and opioid drugs? Opioid drugs include morphine and fentanyl. These opioid drugs work on the same pain receptors that are involved in the endorphin system in your brain. When you take morphine or fentanyl, your brain then releases more dopamine. However, if you take these drugs over a long period of time, then it becomes accustomed to the higher level of dopamine and requires more of the drug in order for you to feel the same level of well-being. In other words, your brain gets used to that amount of dopamine and it no longer works. You need more of the drug to feel the same level of happiness. In addition, becoming addicted to opioid medication can leave a person emotionally and socially withdrawn. You may also find that you lose interest in other rewarding activities like eating food and engaging in sexual intercourse. This is because morphine and other medications can replace the need to find other ways to experience the natural reward system in your brain. You might stop socializing because the medication has replaced your need to form social bonds. In fact, when people must stop taking morphine or are trying to stop a drug like heroin, the withdrawal effects can be the same as someone going through grief: feelings of depression, irritability, periods of crying, loss of appetite, and not being able to sleep. On the other hand, your natural endorphins generally will not reach this same level of saturation to the point that you need more of the same (e.g., exercise, sex, etc.) to achieve the same level of well-being. However, there is a risk of becoming addicted to an endorphin rush and seeking out unhealthy ways to achieve this. Is it possible to become addicted to the feelings of an endorphin rush? Unfortunately, the answer is yes. Below are some examples of how this can happen. Self Harm Persons who self-harm often do this because of the endorphin rush that they experience after hurting themselves. Usually, this is done to relieve emotional stress and becomes a habit where the endorphin rush becomes an addiction and the person can't stop self-harming because of the need to feel that emotional release. Exercise Addiction It is also possible to become addicted to exercise to the point that it is harmful. When someone is working out for hours a day just to feel the effects of endorphins, this can indicate a problem with addiction. Regular exercise is helpful, but if you are exercising to extremes and can't seem to control your behavior, that could be an indication of a problem. Socializing and Endorphins Endorphins are also released when we form social bonds. However, if someone consistently uses opioid medication, they may no longer seek out social connection. By the same token, a person who naturally experiences higher levels of these brain chemicals may have different social motivation. Are you wondering how to increase endorphins and improve your well-being and pain tolerance? Following the suggestions laid out here will give you a good start toward improving your well-being and increasing your pain tolerance. However, it's also important to remember that each person will vary in their own level of pain tolerance and feelings of well-being. If you feel as though your mood is low and nothing is working to improve it, that may be a sign of another issue such as depression or a related illness. In that case, it is best to make an appointment with your doctor to investigate the underlying problem and put together a treatment plan. |
