The Surprising Link Between How You Breathe and How Well You Sleep

Your breath at bedtime is one of the most powerful — and most overlooked — tools for a peaceful night's rest

If you've been waking up in the night, struggling to fall asleep, or feeling oddly tired even after what seemed like enough hours of rest, you're in very good company. Sleep changes are one of the most common experiences adults share after 60 — and they can be genuinely frustrating.

But here's something that might surprise you: there is a deep, well-established connection between the quality of your breathing and the quality of your sleep. The two are intertwined in ways that most people never stop to consider. And the beautiful thing is, understanding this connection opens a door to some of the gentlest, most natural support available — no prescription required.

In this second installment of our Breathe Well series, we're going to explore that connection with warmth and clarity, and share some easy bedtime breathing habits you can begin experimenting with tonight.

How Sleep and Breathing Are Connected

Sleep is not one single state — your body actually cycles through several stages throughout the night, from light sleep to deep sleep to REM (dream) sleep. During each of these stages, your breathing naturally changes pace and depth. In deep sleep, breathing slows and steadies. In REM sleep, it can become a little more irregular.

When breathing is disrupted during the night — even subtly — it can pull you out of the deeper, more restorative stages of sleep. You might not fully wake up, but your body is roused just enough to shift into a lighter sleep stage. The result? You spend less time in the restorative sleep your body truly needs, and you wake up feeling less refreshed.

And it works in the other direction too. The way you breathe in the hours before bed — whether you're tense, rushed, or calm — helps set the stage for the kind of sleep you'll have. Your nervous system picks up on every signal you send it, and your breath is one of the clearest signals of all.

Why Sleep Can Shift After 60 — And What Breathing Has to Do With It

It's very common for sleep patterns to change as we get older. Falling asleep can take longer. Waking earlier in the morning becomes more frequent. The deep, dreamless sleep that feels most restorative may be lighter or shorter than it once was. These are natural changes, and they don't mean anything is wrong with you.

But there are a few breathing-related factors that can quietly make these changes feel more pronounced:

Breathing through the mouth at night

Many people — particularly as they age — shift toward mouth breathing during sleep without realizing it. Nose breathing, by contrast, warms and filters the air, produces a molecule called nitric oxide that supports circulation, and naturally encourages slower, deeper breathing. Mouth breathing tends to be shallower and can make the throat feel dry and irritated in the morning.

A nervous system that stays "on alert"

Modern life — with all its news, responsibilities, and quiet worries — keeps many of us in a low-level state of alertness that's hard to fully switch off at bedtime. When the nervous system stays in "alert mode," breathing stays shallower and faster. The body hasn't yet received the message that it's safe to truly rest.

Reduced natural lung flexibility

As we touched on in Part 1 of this series, the lungs and chest wall become a little less supple over the years. This means the body sometimes has to work slightly harder to take a full, satisfying breath during the night — which can subtly disturb the quality of sleep without you ever consciously waking up.

The "Wind-Down Breath" — Preparing Your Body for Rest

One of the most powerful things you can do for your sleep is to give your nervous system a clear, gentle signal that the day is over and it's safe to rest. Your breath is one of the most direct ways to send that signal.

When you breathe slowly and make your exhale longer than your inhale, you activate the part of your nervous system responsible for rest and recovery. It's sometimes called the "rest and digest" response — the opposite of the "fight or flight" state that keeps us tense and alert.

Here is a simple bedtime breathing practice to try:

A Few More Gentle Habits to Support Nighttime Breathing

The bedtime breathing practice above is a wonderful place to start. And here are a few additional small habits that many people find helpful for supporting better breathing — and therefore better sleep — in the evening hours:

• Try to breathe through your nose during the day. The more comfortable nose breathing feels during waking hours, the more naturally it continues during sleep.
• Give yourself a quiet wind-down hour before bed. Even 20–30 minutes away from screens, news, and stimulating conversations allows your nervous system to begin settling.
• Keep your bedroom air comfortable. Air that is too dry or stuffy can encourage mouth breathing during the night. A slightly cool, well-ventilated room tends to support easier breathing.
• Notice your sleeping position. Sleeping on your side rather than your back can make breathing a little easier and more comfortable for many people — especially if you tend to snore or feel congested at night.
• Release tension from your jaw and shoulders before sleep. Many of us hold tension here without realizing it. A gentle roll of the shoulders and a soft unclenching of the jaw can ease breathing significantly.

Be Patient and Kind with Yourself

If sleep has been a struggle for you, please know that there is no quick fix — and that's perfectly okay. The goal of these gentle breathing practices isn't to promise you eight hours of perfect, uninterrupted sleep from the very first night. It's to offer your body a little more ease, comfort, and signal of safety as it moves toward rest.

Some nights will feel better than others. That's the nature of sleep at any age. What matters is the direction you're moving — toward more awareness, more gentleness, and more care for yourself as the day ends.

Even one slower breath before you close your eyes tonight is a beautiful act of self-kindness. And that's always worth something.
