It was the week before my best friend’s wedding, and my anxiety (nerves, plus excitement) had reached epic levels. I wasn’t sleeping, to say the least. Part of that had to do with the maid-of-honor speech I would be giving. I was terrified and could not shut my brain off to fall asleep at night.
After day three of lying awake until the wee hours of the night, I sheepishly admitted to her that I was too nervous to fall asleep, and she—the bride, who was sleeping like a baby the week before her own wedding—told me I needed to try the “4-7-8” breathing trick.
She happens to be a licensed wellness practitioner who studies meditation, stress, and breathing techniques, and she told me it would change my life. You simply breathe in through your nose for four seconds, hold your breath for seven seconds, and exhale through your mouth for eight seconds. She explained that the studied combination of numbers has a chemical-like effect on our brains and would slow my heart rate and soothe me right to sleep that night. “It works,” she told me. “It’s crazy.”
I couldn’t wait to put the trick to the test, and to my complete disbelief, I woke up the next morning unable to even remember getting to the eighth second of the exhale because it knocked me out that fast. For the next four nights leading up to the big day, even as my stress increased, I was able to fall asleep the minute I tried the 4-7-8 trick. I also used it to relax in the moments leading up to the speech.
When you feel stressed or anxious, adrenaline courses through your veins, your heart beats at a rapid rate, and your breathing becomes quick and shallow. So before I get into the specifics behind how the 4-7-8 breathing trick works, I wanted to explain in my own words what it feels like when you try it. To me, the effect of the breathing technique feels almost like a sedative drug, because in order to hold your breath for seven seconds and then to exhale for eight—when your breath is so shallow and short—your body is forced to slow your heart rate. It has no choice. Holding your breath, and then slowly, deliberately exhaling for eight seconds, causes a chain reaction. It feels like going from a mad-dash sprint to a finish line to a slow, leisurely, calming stroll through the park.
When you first start, you’ll be desperate to just take in another breath, or you’ll want to speed up your counting, but if you stick to the numbers (or at least try to), and don’t take any breaks (in other words, consecutively repeat the 4-7-8 without resuming regular breathing), you can literally feel your heart rate slow down, your mind get quieter, and your whole body physically relax. It washes over you like a calming, relaxing drug. I can never remember getting past the first set of 4-7-8.
Do you know the feeling of being put under by anesthesia, where you are conscious, and the next thing you remember is waking up? That’s what this is like for me: As soon as I start the practice, the next thing I remember, I’m waking up in the morning and can’t even remember beginning the 4-7-8 count the night before. Crazy.
Now to the more technical details: People who are stressed or anxious are actually chronically under-breathing, because stressed people breathe shortly and shallowly, and often even unconsciously hold their breath. By extending your inhale to a count of four, you are forcing yourself to take in more oxygen, allowing the oxygen to affect your bloodstream by holding your breath for seven seconds, and then emitting carbon dioxide from your lungs by exhaling steadily for eight seconds. The technique will effectively slow your heart rate and increase oxygen in your bloodstream, and may even make you feel slightly lightheaded which contributes to the mild sedative-like effect. It will instantly relax your heart, mind, and overall central nervous system because you are controlling the breath versus continuing to breathe short, shallow gasps of air.
