How to Calm an Anxious Mind Before a Big Day

How to calm anxiety before a big day comes down to timing: a five-minute to-do list the night before, a brisk walk that morning and a zero-to-ten check in the last ten minutes. Anxiety before an interview and nerves before a presentation run on the same stress response.

Those nerves are an old survival system working a little too loudly, and because they show up in the body, they often ease with the same small, physical coping skills for anxiety that help on any hard day.

Why Is It So Hard to Calm Anxiety Before a Big Day?

Because your body is treating the day as a threat. When something feels high stakes, the amygdala signals the hypothalamus, your adrenal glands release adrenaline, and your heart and breathing speed up. If the brain keeps reading danger, a second system, the HPA axis (hypothalamus, pituitary gland and adrenal glands), releases cortisol, which keeps the body revved up and on high alert until the threat passes, as Harvard Health explains.

This system can also overreact to stressors that are not life-threatening, such as work pressure. Before a performance, Cleveland Clinic notes, your heart rate can go up, your hands, legs and voice can shake and your mouth may feel dry. The aim is to keep that response from running too high.

Some of this helps. Researchers describe anticipation as an adaptive process that mobilizes you to prepare, though in excess it feeds rumination and worry (Goldstein and colleagues, 2013).

Your Timed Checklist for the Night Before and the Morning Of

Six timed steps, from a few hours before bed to the final ten minutes, each with its reason. Logistics come early to leave the evening for winding down, and movement comes before you arrive. Shift the times to fit your day.

What Helps Anxiety the Night Before an Event?

Start with a list. Bedtime worry about unfinished tasks is a significant contributor to trouble falling asleep. In a sleep-lab study of 57 healthy young adults, those who spent five minutes writing a to-do list for the coming days fell asleep in about 16 minutes, against about 25 for those who listed tasks they had already finished (Scullin and colleagues, 2018). A secondary analysis, which the authors call too small to settle it, linked writing more items on the to-do list, the study’s measure of how specific it was, to faster sleep. It was one night in a lab, so call it promising.

Make yours concrete (“leave at 8:10,” “print two copies”), and if a new worry surfaces after lights out, add one line and lie back down.

Then protect your sleep window instead of forcing sleep. In a 2020 study in Nature Human Behaviour, even modest night-to-night reductions in sleep predicted next-day increases in anxiety (Ben Simon and colleagues).

That is a reason to wind down early, not to panic; our post on how to relax before bed has a fuller routine.

In bed, breathe in through your nose for four counts and out for six. Slow breathing, a basic form of breathwork, aims to bring on what the National Center for Complementary and Integrative Health, part of the NIH, calls the relaxation response: slower breathing, lower blood pressure and a reduced heart rate, the opposite of the stress response (NCCIH).

What Should You Do on the Morning of a Big Day?

Move for five to ten minutes. Cleveland Clinic lists exercise as one way to discharge performance tension, since moving releases endorphins that can help override your stress response, and suggests a walk or a few jumping jacks. A brisk walk to the venue counts.

Otherwise, keep it boring: your usual wake time, a familiar breakfast, no extra coffee if it makes you jittery.

What to Do in the Final 10 Minutes

In the last ten minutes, rate your nerves from zero to ten. Above a five, shake out your whole body, then take three to five slow breaths; at a three or four, a few slow breaths may be enough. A licensed social worker interviewed by Cleveland Clinic explains the scale she uses as a rule of thumb:

I think about rating anxiety on a scale of zero to ten. We never want to be at zero. But if we go over a five, our brain switches over, and we’re not responding in a logical way anymore.

Shake it out. In a restroom or a quiet corner, give your whole body a big wiggle, flailing your arms and shrugging your shoulders if your body permits. Cleveland Clinic says this can help release built-up anxiety; 30 seconds is plenty.

Then breathe slowly, with the out-breath longer than the in-breath; that ratio is our suggestion. The evidence is early: NCCIH describes a 2019 review of three studies, 880 participants in all, with preliminary evidence that diaphragmatic breathing may reduce stress, including promising changes in cortisol and blood pressure. That evidence is for breathing exercises, not a few breaths before you walk in, so treat this as a way to steady yourself, not a proven fix. NCCIH also notes that relaxation techniques occasionally leave people more anxious. If that happens, name five things you can see instead, one of several grounding techniques that work in a hallway.

If it helps, name the feeling: “This is my body getting ready.” For a two-minute reset at your desk, see our post on workplace anxiety.

InnerSmith is being built for nights and mornings like these, matching a short breathing, movement or grounding exercise to how your day actually feels, whether that is wired at 11pm or jittery in a parking lot. It is pre-launch, with a waitlist open for early access.
