Overthinking is a loop that pretends to solve things and instead keeps you stuck. Here is how I help people pause a loop, including when it hits at night and will not let go.

Short answer. You stop overthinking by pausing the loop, shifting it to the body or to paper, and giving the mind a smaller job. Thoughts keep coming. You can change how you relate to them, and you can train that during the day so it shows up at night.
In short:
When I say overthinking, I mean a loop that feels like problem solving and behaves like quicksand. It just keeps circling. Your mind runs the same angles, checks the same facts again, rehearses conversations without moving them forward, and the body quietly climbs into alert mode as if a siren were sounding behind your ribs.
In the day, loops often hitch a ride on work, money, health, or whether a message was rude. Nights magnify small noises and shrink your sense of options. Beds get linked with planning, and I see people try to think their way out of a feeling and end up with both: a tight chest and a tired mind the next morning.

Go small first today. Give your brain a job so clear it cannot argue, while you let your body catch up: name five things you see, place both feet flat, sip cold water, press your back into a wall for thirty slow counts while your shoulders drop away from your ears.
If the loop is about a decision, shrink the field. Write two options only. Then write one next step you can actually do today. Keep it boring and concrete; a loop starves when there is nothing left for it to chew, and your hands doing one small action keep you honest.
Night really is different. With less input, the room goes quiet and every thought sounds louder, so park it to paper. Keep a small notepad by the bed, write the worry as a one-line title and one next step, then say, in normal voice, "Tomorrow." The ritual matters more than the content.
If you are staring at the ceiling after twenty minutes, get up. Keep lights very low. Skip the scrolling that overheats the brain, and pick a boring, repeatable task like folding two shirts or rinsing a cup. Two cycles of a slow 4-7-8 breath can help the body remember sleep, and warm feet, a cooler room, a covered clock face, and dark chargers reduce bait for the loop.
Brains are built to predict and protect. Bodies set the volume. That shows up more when you are stretched thin, under-slept, or running on caffeine and adrenaline, so a calmer body gives the mind less noise to misread as threat. Planning is useful until it loses the plot and starts scanning for danger.
If your Sundays feel heavy, that anticipatory thrum has cousins in overthinking. I wrote about that here: The Sunday evening feeling. Long burnout phases also feed loops because everything costs more effort; this piece may help you tell that story in plain words: Burnout and depression look the same from the inside.
Your safety comes first. If you feel unsafe, or your thoughts include harming yourself or someone else, or you cannot care for yourself through the day, call Tele-MANAS on 14416. That line runs all day and night. If you hear or see things others do not, or cannot sleep for many nights in a row, see a psychiatrist; medication may be part of care, and I refer when that makes sense.
I work with adults roughly 25 to 45. If you are younger than 25, this is not my room. People who want a productivity hack will get irritated here. This is practical, yes, and it respects that your mind is trying to help even when it overdoes it.
Start with a chat. I am Satlaj Sachan, counsellor in Bengaluru, practising since 2015, and I have worked with more than 140 people. Sessions happen in English or Hindi, over video or in person in Bengaluru. I am not a doctor, so I do not prescribe; if medication is worth considering, I refer.
A first conversation is thirty minutes and free, and booking runs through a form first; read what we cover here: What happens in a first conversation. The practice is called Rafiq, at heyrafiq.com, a name from my podcast running since 2020. I also run a small gathering in a cafe in HSR, Bengaluru; five or so people, the day moves week to week, and it is not counselling.
How do I stop overthinking quickly when it spikes at work?
Step away from the screen, even for two minutes. Cold water on wrists, feet flat, one slow breath that is longer on the exhale, and a short note on paper about the very next step. Give your brain a smaller job. Come back to the task with that one step in front.
What should I do when I wake at 3 am and cannot stop thinking?
Keep the room dim. Write the headline of the worry and one next step on a small notepad, say "Tomorrow," then try a 4-7-8 breath twice. If you are awake past twenty minutes, get up and do a dull, repeatable task. Return to bed when your eyes feel heavy.
Can counselling stop overthinking for good?
Counselling changes how you meet thoughts. We build habits that make loops shorter and less sticky, and we check the conditions that feed them. Some people notice more space in their head; some need other supports too. If medication might help, I refer. There is no universal, permanent switch.
Is overthinking the same as anxiety?
They overlap. Overthinking is a thinking pattern that can ride on top of anxious energy in the body. Anxiety is more than thoughts; it lives in breath, muscle, sleep, stomach, and pace. Calming the body often reduces looping. This may help you sort signals: Do I need therapy or am I overreacting?.
Should I try to replace every negative thought with a positive one?
Replacement can turn into arguing with yourself and give the loop more airtime. I prefer naming the loop, parking it to paper, and giving the brain a small action that changes your position in the room. It is kinder and it breaks the cycle without a debate you cannot win at 2 am.
