Antidepressants are often a first-line treatment for mental health issues, such as anxiety or depression, which highly sensitive people are at a greater risk of developing.¹
Between 2015-2018, around %13.2 of American adults took antidepressants, and with the onset of the pandemic it’s likely those numbers have gone up.²
Because of their effectiveness and widespread use, it is worth investigating: Is there science behind our sensitivity being affected by antidepressants?
Emotional Blunting
It is proven that sensitive people are strongly affected by medication.³ A study conducted by Eliane and Arthur Aron, among others, proved that “the higher a study participant’s HSP score the more intense their reactions to medications”.
Furthermore, it is shown that those who experience sensitivity to medication will also show more signs of adverse effects, which means highly sensitive people are at an increased risk for side effects.
In my experience with antidepressants as an HSP, normal doses are very strong, and it feels like they put me in the body of a non-HSP, but still with my sensitive mind. What I mean by this is that my capacity to be sensitive or rather display the traits of my sensitivity were wiped out. I noticed an inability to be as empathetic and connect with people as deeply and emotionally. While depression and anxiety were certainly reduced, there was a dimness in my life during that time because of my inability to feel emotion.
Part of the reason I experienced this effect on my emotions was because of a common side effect of antidepressants known as emotional blunting.⁵ According to NeuroLaunch, Emotional blunting is “a state where a person experiences a reduced ability to feel or express emotions, both positive and negative”.⁶
Highly sensitive people can be particularly damaged by emotional blunting because of how much joy we get from being able to connect emotionally with our surroundings. If we see our ability to feel and express emotions as features of our sensitivity, then emotional blunting certainly can suppress our sensitivity.
Furthermore, emotional blunting is shown to have an impact on creativity, empathy, and even ability to cry. Many people see these things as components of their sensitive mind.⁷
Deciding whether these side effects are worth it involves understanding if you would lose yourself without your usual ability to feel, or if taking the medication is a needed break from emotional intensity.
Our Pause-to-check System can be Affected
Elaine Aron, in The Highly Sensitive Person, discusses the possibility of HSP’s “pause-to check” system, also known as the behavioral inhibition system, being affected by antidepressants.¹
The pause-to-check system, which is often strong in HSPs, controls our attention to danger, and helps us be “alert, cautious, and watchful for signs (of danger)”.¹
The way that antidepressants could reduce our sensitivity, according to Dr. Aron, is that they “stir up” our behavioral activation center to “counteract (our) pause-to-check system.¹ The behavioral activation center does the opposite of our pause-to-check system, meaning it is “responsible for initiating and regulating goal-directed behavior.”⁸
So, if our pause-to-check center is run over by our behavioral activation center because of taking antidepressants, we may be more likely to do things less mindfully and an extra step in our sensitive way of decision-making would be missing.
However, this change is not completely bad as Aron points out that people with a quiet behavioral activation center, who probably come across as shy, could benefit from antidepressants because the drug may reduce their shyness and make it easier to initiate action.
Fortunately, there are also positive ways antidepressants can impact our sensitivity.
Reduced Overstimulation
Being easily overstimulated is seen as a key component of being highly sensitive.¹ PsychMechanics describes it as "when the sensory information you receive from one or more of your senses exceeds the information processing capacity of your brain".⁹ Overstimulation is also one of the hardest parts of being sensitive, as we reach this state quicker as overstimulation can negatively affect our lives in countless ways. Ultimately Dr. Aron believes that antidepressants can move us into a more optimal state of arousal from our overstimulation.¹
Antidepressants “work by balancing neurotransmitters in the brain, which can help regulate emotional responses to stimuli.”.¹⁰ They also increase the levels of serotonin in the brain, which can help regulate mood and reduce anxiety.
So, it seems that this help with balancing neurotransmitters could reduce our overstimulation. This could allow us to do things like socialize or work longer without getting overstimulated. Or maybe it could allow us to multitask or focus better.
It could also allow us to cope with performance anxiety, such when speaking in public, which HSPs often struggle with.¹¹
Mental Health
Antidepressants can be life-changing for HSPs who have struggled with depression, anxiety, mood instability, and other mental health conditions.
While we may want to be like others who aren’t on medications or people who "beat” their depression, as HSPs our brains are wired differently and some of us may find that antidepressants are what’s best for us. Or we may decide that we don't feel like ourselves when we're on them. Either way, will discernment and speaking with a doctor, you can decide what's right for you.
Conclusion
While many factors come into play when choosing to take antidepressants, there is science behind antidepressants changing our sensitivity in good and bad ways.
There are certainly many more life-changing benefits that antidepressants can offer in HSPs lives, but I tried to focus specifically on areas of our sensitivity that could be affected by it.
