Teenage Rage!: The Science Behind Mood Swings and How Parents Can Help

Out of Control!

If you have an adolescent living under your roof, you know full well that their hormonal changes can lead to some pretty wild mood swings! They may manifest differently: some teenagers lash out loudly and aggressively, while others might retreat into a moody, standoffish silence, and still others might melt down in a pool of uncontrollable tears. But what they all have in common is this: our children, whom we have watched lose their minds in so many different ways throughout their young lives, are transitioning into young adulthood with some pretty extreme growing pains! And when they lose their minds now, it tends to be bigger, hairier, and scarier than when they were little kids!

It is incredibly important to be open to discussions about emotional dysregulation with our adolescent children. With the myriad of changes the teenage years bring: flooding hormones changing their bodies, social norms and rules changing in their peer groups, academic expectations ramping up, responsibilities on the home front getting larger, first jobs and extracurricular activities absorbing previously free time, and the ever-looming future of adulthood casting a pall of anxiety over the choices they make, the grades they earn, and the clubs they join, it is incredibly understandable why these years can lead to some powerful mood swings. From anger to anxiety to sadness to depression to ennui to lack of motivation, our adolescents run a gauntlet of overwhelming emotions as they navigate this critical period of development, and it is important for us as their parents to recognize that not only can we NOT let our children “be free” of our guidance yet, but rather, that we must work harder than ever to parent them through these years.

 

Know the Science

Teaching our children the science behind what is happening in their brains empowers them to label their feelings and to understand that they are perfectly normal and even expected. Their out-of-control feelings and mood swings are the direct result of their surging hormones. Teens and tweens will experience stronger emotions, faster, than their brains experienced when they were younger. Their limbic system, the emotional part of the brain, sends and receives signals faster than any other part of the brain during these years. When your tween daughter, therefore, cannot find a shirt that she likes to wear to school in the morning, she may just have a complete emotional meltdown that looks downright baffling to you as her parent. Telling her “It’s no big deal!” will not have a pacifying effect, but rather, will only exacerbate her tornado of emotions. 

Our adolescents’ surges of sex hormones (estrogen, testosterone, progesterone) actually change the way their neurons fire in their brain and change the way they experience emotion. These are called hormonal mood swings, and kids have wild rises and falls of these hormones through any given day. Generally, they do not want to feel out of control, and most kids want to do well and be good members of their family, so these mood swings can lead to feelings of self-loathing or disappointment. Interestingly, while girls’ hormonal outbursts are often associated with moodiness, boys experience elevated levels of testosterone, which are associated with both rage and anger as well as retreating and silence. These hormones fundamentally alter the brain structures of our children during adolescence by stimulating the growth of new neural connections, increasing the number of synapses and therefore expanding the speed of information flow, and also by activating certain neural systems that favor reward-seeking behaviors. Teenagers are highly sensitive to criticism and praise, seeking people and situations that reward the brain more powerfully than it would an adult brain (Science Insights). Connect these developments to an easily activated dopamine system, which rewards teenagers with feeling happiness at a faster pace than that of an adult, and our teenagers are far more likely to respond powerfully to exciting or risky behaviors.

Moreover, the human brain does not finish maturing until the mid-20s, and the last region to fully develop is the prefrontal cortex – the area that handles impulse control, long-term planning, and emotional regulation. However, the amygdala, which is the area of the brain that processes threats and strong emotions, is fully active during the teen years (Science Insights). Not only does the teenage body have a flood of hormones coursing through it, but it also has a brain that generates intense emotional responses at a time when the part of the brain responsible for putting those emotions in context is not yet completely developed (Science Insights)! If our kids are overreacting to situations, it is not because they have something fundamentally wrong with them, but rather, it is a sign that their brains and bodies are doing exactly what they should be doing developmentally! If you take the time to teach your child the science of what is happening in their brains, you are giving them an explanation that they can hold on to and take comfort from. While they might not be able to properly regulate their emotions in the moment, they at least know that what they are feeling is perfectly normal, and that as they grow older, these tough emotions will become easier to manage.

 

Emotional Regulation Strategies

When your child is in a less heightened state of hormonal emotion, it is always a good idea to revisit an emotional episode and talk about what happened and why, in a nonjudgemental way. Remember, our role as parents is to teach our kids how to deal with the difficulties of being fully human in a world surrounded by other fallible humans. We cannot shield them forever from bad things, but we can teach them coping strategies. Therefore, we want to give them space and grace to discuss what they felt and why, and then open up the conversation into potential strategies that they might be able to use when they get these surging emotions in the future. With my children, we have discussed not only strategies for how they want to deal with their own outbursts (be left alone in their room until they are ready), but also how the rest of us should respond in order to make the moment more manageable to the out-of-control child (do not engage with them, even to ask if they are okay, because that will trigger further outbursts rather than mollify). 

The following are some potential strategies our kids might employ when they are feeling out of control:

• Let them remove themselves from the situation. Have a comfortable, private space to retreat to. If your teen/tween shares a bedroom with a sibling, then either work it out as a family that one sibling might have alone time in the bedroom, or else work out a different space in the house that can function as a private retreat.
• Let them put their head in a pillow and scream, punch a punching bag, write scathing things in a journal, and then return once they feel more in control of their emotions.
• Let them listen to music. Some parents get upset when their child “disappears” into their headphones, but it is a known fact that listening to music can calm the body and mind, and can serve as an escape from wild emotional swings.
• Let them spend time with a friend. Friends can also be amazing emotional regulators. As much as you might want to ground your child for having an attitude, take a moment to consider if a more effective and productive strategy might be to let them spend time with a good friend instead. If you do this, let them know up front that this is your reasoning. They are not “getting away” with bad behavior, but rather, you are teaching them that there are healthy avenues out of their negative moods.
• Spend more time with them. This is the opposite of the first suggestion, and both of these differing approaches depend largely on your individual child. Some children need to remove themselves in order to regulate, while others may regulate with the assuring company of a caring adult. Do something light and easy, whether it is watching a TV show together, doing work side-by-side at the table, or walking the dog. Don’t go into this time having great expectations for revelatory conversations. Sometimes, your child’s emotional outbursts truly aren’t that deep.
• Give them a project. Our brains thrive on having something to work on and through. Sometimes all they need is a distraction from their emotions in the form of a project. So perhaps it is a good time to have your trash cans cleaned out, your yard weeded, or your photographs organized.
• Let them go on a walk or on a run. Exercise reduces stress by lowering the levels of the stress hormones cortisol and epinephrine, and it also helps boost the production of endorphins, which are known to improve mood and promote relaxation. By letting your kids feel the control exercise gives them over their emotions, they will feel empowered to employ this strategy in their own futures, making them more resilient to life stressors in general.

When it is Something More

Teenage mood swings are normal and expected during this stage of development, and while it may try your patience and your parenting skills, it is nevertheless an understandable hurdle that your children must leap over on their way to becoming well-adjusted adults.  It is, however, important to note that not all teenage mood swings are considered normal and expected. When these mood swings are temporary and caused by certain events or triggers, they are not anything to seriously worry about. However, parents should be on the lookout for more serious emotional and psychological issues such as anxiety or depression.

Clinical depression often looks different in adolescents than it does in adults. Rather than looking and feeling “sad” as adults may feel, teens are more likely to experience depression in the form of persistent irritability, a rapidly shifting mood, physical complaints like a headache or stomachache, social withdrawal, sleeping too much, and an increased appetite (Science Insights). The most important thing to look out for is persistence and duration. When their mood shift lasts for more than two weeks with very few changes on a daily basis, plus three additional symptoms: significant changes in weight or appetite, sleep disruption, fatigue, feelings of worthlessness or guilt, difficulty concentrating, or thoughts of death, then you are probably dealing with clinical depression or a persistent depressive disorder (Science Insights), and should immediately seek professional care for your child.

Be There for Them!

By the time our kids are teenagers, we are no longer perfect in their eyes. They know we are fully rounded human beings with faults and failings and strengths and problems all our own. But just because they know that we are as human as they are does not mean that they no longer need us or care about what we have to say. The best thing that we as parents can do for our teenagers as they deal with their ever-changing bodies and minds is to let them know that we are there for them, that we understand that they are going through some difficult changes, and that we care about them. If we are able to talk to them about what is happening to them and give them practical advice when it is solicited, then they will be more likely to continue to come to us when they have questions or concerns. It is okay to not have all the answers. In fact, your teenager is just as capable of looking up information on Google as you are! When they are approaching you for insight or help, what they really need the most is to know that you are listening to them and that you will support them in whatever way you can. Take joy in being on this wild ride with your teenager, because once they are adults, your relationship will change yet again!
