Most of us breathe through the mouth — without realising.
adults are mouth breathers.* Your nose is built for the job — it filters, warms and slows your breath, nudging your body toward calm. Flow is a gentle reminder to use it, day and night.

Your nose is built for the job.
Filters every breath
Tiny hairs and mucous in the nose trap dust, pollen, allergens and pathogens before they reach your lungs. Your mouth doesn't filter at all — it's a direct line in.
Warms and humidifies
Air takes a winding path through the nasal passage — warming to body temperature and picking up moisture before it hits your lungs. Kinder on the airways, fewer sore throats, less morning dryness.
Releases nitric oxide
Nasal breathing produces nitric oxide — a vasodilator that opens blood vessels and helps oxygen reach your cells more efficiently. Mouth breathing skips this entirely.
Triggers calm
Slow, deep nose breaths activate your parasympathetic nervous system — the rest-and-digest mode. Heart rate steadies, breathing slows, the day feels less wired.

Nasal breathing, answered
Why is nose breathing better than mouth breathing?
Your nose is built for the job. It filters dust, pollen and pathogens, warms and humidifies the air before it hits your lungs, slows the breath rate so your body can relax, and produces nitric oxide that helps your cells use oxygen better. Your mouth does none of that — it's a fast, unfiltered, dry line straight into the body.
Can I really change a lifelong breathing habit?
Yes. Most habit research suggests new patterns become automatic within 2–4 weeks of consistent use. Most people notice a change within the first week of using Flow, and find the difference fully settled in by the end of the first month.
How long until I notice a difference?
Within the first week, most people feel calmer mornings and less morning dryness. By the end of week two, sleep usually feels deeper and partners often notice it first. Give it a full month for the habit to fully embed.
Is this safe to use every night?
Yes — Flow products are designed for nightly use. If you have any respiratory condition, sleep apnoea, or are congested or unwell, take the night off and chat to your GP first.
Do I need all three products?
Not at all — start with what fits your life. Many people start with just the mouth tape to fix overnight breathing, then add the nose strips for daytime once they feel the difference. The band is for athletes, frequent flyers, and reusable-everything people.
