When Your Tolerance Threshold Drops
Overload rarely shows up only as obvious, easily recognizable distress. It often appears in more subtle ways: shorter patience, quicker anger, a feeling that everything is too much, or an unusually strong reaction to something seemingly insignificant.
Stress can be associated with irritability and feelings of being overwhelmed; changes in sleep can also occur among the behavioral changes linked to stress. [1]
Sleep, however, is not an insignificant factor in the background. Harvard Medical School points out that sleep and mood are closely connected, and that insufficient sleep can increase irritability and sensitivity to stress.[2]
That is why, on a day when you are well-rested and calm, the sound of someone typing may barely register. But when sleeplessness, deadlines, worries, and the feeling that you are constantly available to others start piling up, the same sound can feel almost unbearable.
The stimulus is the same, but your internal threshold is not.
"This person is getting on my nerves" is not always the same as "my system currently has very little tolerance for stimuli."
Sometimes Tension Simply Needs an Outlet
When we carry a lot of unexpressed frustration or mental strain, it is not unusual for irritability to latch onto something very specific: a coworker’s sipping, a partner’s chewing, or the sound of phone notifications. This does not mean that the small habit is insignificant. It may simply mean that it is not the only reason behind your reaction.
A useful, non-judgmental question to ask yourself is this:
If I were well-rested, well-fed, free from time pressure, and had enough peace and quiet, would this still bother me just as much? If the answer is “probably not,” it may be worth turning your attention inward. Not to minimize your feelings, but to identify what actually needs your attention.
Too Many People, Too Little Space for Yourself
Sometimes irritability appears simply because we have been in “social mode” for too long. Work, meetings, messages, family responsibilities, and the constant need to be available can create the feeling that we are never truly alone.
At that point, even the presence of other people can become exhausting, including people we love and normally appreciate.
This does not necessarily mean that you are antisocial or want to avoid people. It may be a signal that you need fewer stimuli, less communication, and some time without other people’s expectations. A short break without your phone, a quiet walk, lunch in silence, or a few minutes in a space where no one is asking you for anything are not luxuries. During periods of high stress, they can be a basic form of recovery.
When Could Misophonia Be Behind It?
If very specific sounds consistently trigger a disproportionately strong reaction in you—for example, chewing, sipping, swallowing, breathing, clicking a pen, or typing—misophonia may be one possible explanation.
It refers to a reduced tolerance for certain sounds or sound-related stimuli, which can quickly trigger intense feelings of irritation, anger, anxiety, or disgust. [3]
The pattern is important. It would not make sense to conclude that you have misophonia based on one stressful day or simply because your coworker’s sipping bothers you once. It is worth paying attention when the triggers are very specific, the reaction keeps recurring, and it significantly interferes with your work, relationships, or everyday life.
| Question to Ask Yourself |
What It Can Help You Notice |
| How have I been sleeping over the past few days? |
Whether your patience has decreased due to fatigue. |
| Have I eaten and had enough to drink today? |
Whether your irritability increases when your body is low on energy. |
| How many things are currently on my mind? |
Whether stimuli become more intense when you are under significant mental pressure. |
| Have I been around people or responding to others all day? |
Whether you need some space and fewer social demands. |
| Does almost everything bother me, or mainly one specific sound? |
Whether this is more likely to be general overload or a recurring, specific trigger. |
A Small Experiment for Next Time
The next time someone suddenly gets on your nerves, you do not have to suppress the feeling or punish yourself for having it. Start by simply naming it: “I’m really on edge right now.” Then, if possible, take a short break. Get some water, change rooms for two minutes, step away from the noise, or consciously slow down your exhalation a few times.
Only then ask yourself what you need. Perhaps better sleep. Maybe fewer meetings in a row. Perhaps a warm meal and ten minutes without a screen. Maybe a conversation about the pressure that has been building up.
Official NHS guidance on managing stress also includes making time for yourself, talking to someone close to you or a professional, and using simple breathing exercises. [1]
The goal is not to never feel irritated again. The goal is to prevent the first wave of irritation from carrying you straight into conflict or guilt.
When you understand what the feeling is trying to tell you, you can respond to it more gently and more effectively.When Is It a Good Idea to Seek Support?
If your irritability lasts for several weeks, becomes more intense, interferes with your work, affects your relationships, is accompanied by significant distress, or you feel unable to control your reactions, consider talking to a doctor, psychologist, or another qualified professional. Seeking support is not an overreaction; it is a way to avoid being left alone with something that has been draining your energy for too long. The NHS specifically emphasizes that it is worth seeking support when stress affects your daily life. [1]
So perhaps the problem is not the coffee. And perhaps it is not even your coworker.
Sometimes the most honest answer is simply that your system is tired of too much, and that you deserve a little more peace, space, and understanding.
