Count the caffeine and nicotine before you blame the stress

A shift ends, your chest is tight and your hands are jumpy, and what gets you through is a coffee, a cigarette, a drink, or something from a vending machine. This page is about one misreading in that moment. Some of what you feel may be the stimulant and not only the job.

If you feel wound up at work, count your caffeine and nicotine before you blame the stress alone, because both are stimulants that can add to the wound-up feeling, and cut caffeine down gradually and not all at once.

Some people say that caffeine and nicotine are stimulants that raise the body’s stress response and do not relieve it, and that real rest comes from sleep, exercise or time outdoors. That is the belief the rest of this page checks against the agencies that look at it. If you drink heavily every day, or the job itself is the main thing hurting you, read the last section first.

What the agencies say about the jitters

The US Food and Drug Administration lists increased heart rate, heart palpitations, high blood pressure, trouble sleeping, anxiety, jitters, an upset stomach, nausea and headache as effects of too much caffeine. The US National Institute on Drug Abuse says the rush of adrenaline from nicotine raises blood pressure, breathing and heart rate. The NHS lists stress and anxiety, caffeine and nicotine side by side as triggers of heart palpitations. So the pounding heart you put down to the day can come from stress, from the stimulants, or from both, and only a doctor can tell you which.

Count first, before changing anything. Add up the cups, the cans, the cigarettes or vapes, and the hidden caffeine the FDA names: some bars, gum, supplements and over-the-counter medicines. Then look at when the jumpy feeling is worst.

The calm after a cigarette

Some people correct the idea that a cigarette relaxes the body. They say it is a stimulant that raises the heart rate and that the relief you feel is the craving ending, not true relaxation. This page could not find an agency that says the relief is the craving ending. What the National Institute on Drug Abuse lists as withdrawal includes irritability, craving, depression, anxiety, trouble concentrating, sleep problems and increased appetite, which it says usually peak in the first few days and ease within a few weeks, though for some people they last for months. It also says the ritual of handling and lighting a cigarette becomes tied to the craving through learning. That is a reason to keep the break and change what is in your hand. One person says a special non-alcoholic drink as a nightly ritual can give the same sense of looking forward to something as drinking does, without the alcohol.

Help with stopping is in the FAQ below, and there is a page here on treating the hand habit and the nicotine separately.

If you say you need the caffeine to perform

Some people who answered someone who said caffeine could not be cut replied that it is a stimulant that worsens anxiety and sleep, which hurts the performance it was meant to protect, and that the felt need may be dependence. They say it can be reduced gradually. The FDA says to reduce gradually, and that withdrawal is unpleasant but not dangerous. There is a page here on keeping every cup of the ritual and weakening what is in it. How to stay sharp while you do it is not covered here.

What people put in the gap

The NHS says to try not to use alcohol, cigarettes, gambling or drugs to relieve stress, because they can contribute to poor mental health, and lists talking about your feelings, exercise and breathing exercises as things that help. Some people say the body comes first after a shift: a walk, a bath or foot soak, stretching, because the tension sits in the body. Some people say simple, low-energy things for the hands and ears work when you are too tired for anything else: puzzles, reading, colouring, audio. Some people say to leave work at the door in your head too, because worrying outside paid hours is unpaid and costs you. One person says breathing exercises work better if you practise them daily away from work, so they are ready when you need them.

People disagree about where to start. One side says working on how you think about work, such as separating what you control from what you do not, is the main thing. The other side says that advice is obvious and hard to use, and that a physical outlet or a practical change like sharing out tasks does more. What decides it, they say, is whether you respond better to working on your thinking or on your circumstances. The NHS list above holds both kinds, so you do not have to pick one.

The NHS says to see a GP if you are struggling to cope with stress, if what you are trying is not helping, or if you would like a referral. In the US, a primary care doctor or a community health centre is the same first step.

Who this page is not for

If you drink heavily every day, do not use this page to stop: see the safety box above and see a doctor before you cut back.

If you are pregnant or breastfeeding, take medicines, have a heart condition, or find even a little caffeine hits you hard, ask your doctor before you change anything, as the FDA says.

If the job is the main problem, a coffee swap will not fix it. Some people point out that a workplace that is itself abusive or exploitative is not something a habit or a change of mindset can fix. Others say that when the load is the problem, delegating and setting boundaries inside the role can lower it. What decides it, they say, is whether the stress comes from volume and responsibility, which delegation and boundaries can reduce, or from a mismatch between you and the role, which they say they cannot. Some people suggest the bare minimum is the only way to stop the stress; one person warns that it can risk a performance plan or dismissal. None of this is checked against an authority here.
