You’re exhausted, you lie down, and your mind picks that exact moment to replay every email and rerun tomorrow’s meetings. Sound familiar? Let’s fix it.

A racing mind at night isn’t a character flaw — it’s a nervous system stuck in the “on” position. All day you live in sympathetic mode: alert, driving, solving. To sleep, you have to shift into parasympathetic mode — rest and repair. The switch runs through your vagus nerve, and the good news is you can flip it on command.

Start with your breath, because it’s the one part of the nervous system you can steer directly. Try the physiological sigh: two quick inhales through the nose, one long slow exhale through the mouth. Do five rounds. The long exhale tells your body the threat is over. Within a couple minutes your heart rate settles and the mental noise fades.

Next, get present. Most nighttime spinning is time travel — rehashing the past or rehearsing the future. Eckhart Tolle’s point lands here: the only place life actually happens is now, and right now, in bed, you’re safe. Put your attention on the physical feeling of breathing. When a thought grabs you, gently come back. You’re training a skill, not chasing perfection.

Set the stage, too. Dim the lights an hour before bed, screens down, room cool and dark. You’re not fighting your biology — you’re cooperating with it.

Catch this pattern early. Poor sleep quietly raises stress hormones and wears down your health over years. Fixing your wind-down is one of the highest-return moves you can make.

Small steps: sigh it out, come back to now, dim the lights. Be your own scientist tonight.
