Breathing ex. also helps us to lower blood pressure & sleep.
From Meta Ai
Yes, it helps a lot — it's one of the few sleep tricks with strong evidence behind it.
Not because of oxygen, but because it forces your nervous system to switch from fight-or-flight to rest mode.
*How it works:*
- Slow exhale activates your vagus nerve -> heart rate drops, blood pressure drops, cortisol drops
- It distracts your brain from looping thoughts — you can't worry and count breaths at the same time
- CO2 rises slightly, which makes you naturally sleepier
*The 2 that work best for sleep:*
*1. 4-7-8 (best if you can't fall asleep)*
- Inhale through nose 4 sec
- Hold 7 sec
- Exhale through mouth 8 sec, making a whoosh
- Repeat 4 cycles. Do it lying down, lights off.
*2. Extended exhale (best if you wake at 3am anxious)*
- Inhale 4 sec, exhale 6-8 sec
- No hold. Just make exhale longer than inhale
- Do for 2-3 minutes. Put one hand on chest, one on belly — belly should rise more.
*What studies show:*
- People doing breathing exercises 20 mins before bed fall asleep ∼12 minutes faster on average
- Improves sleep quality for insomnia, especially when done daily for 2+ weeks
- Works even better paired with no phone + dim lights 30 mins before
*Tips to make it work:*
- Don't force big breaths — gentle, quiet breathing is better than deep gasping
- Through nose if possible — it slows air naturally
- If 4-7-8 feels too long at first, start with 3-3-6
- Do it at the same time nightly — your brain learns "this breathing = sleep time"
It won't override 3 coffees at 6pm or scrolling till midnight, but for racing thoughts and light insomnia, it's one of the most effective non-drug options.
Do you have trouble falling asleep, or staying asleep through the night?
