About this tool
The 4-7-8 technique, popularized by Dr. Andrew Weil, is a paced breathing exercise: you breathe in quietly through the nose for a count of 4, hold the breath for 7, and exhale slowly through the mouth for 8. The defining feature is the long exhale, twice the length of the inhale, which strongly engages the body's relaxation response.
A longer out-breath is one of the most reliable ways to slow the heart and calm the nervous system. By holding for 7 and stretching the exhale to 8, this pattern deliberately lengthens that calming part of the cycle, which is why many people find it useful for falling asleep, easing anxiety, or settling racing thoughts.
Begin with no more than four full cycles in a sitting, and keep the breathing gentle rather than forced. The counts matter less than the ratio: as long as the exhale is clearly longer than the inhale, you are getting the benefit. As it becomes familiar you can do it more often.
If you feel dizzy or short of breath, stop, breathe normally, and try again later with shorter, gentler counts. It is meant to feel soothing, never strained.
This pattern is not the right fit for everyone. People who are pregnant or who have a diagnosed respiratory condition such as COPD or severe asthma should check with a doctor before practicing extended breath holds, since holding the breath changes blood oxygen and carbon dioxide levels more than normal breathing does. Anyone who feels panic rather than calm while holding the breath should simply breathe slowly without the hold.
The calm rating at the end is a way to notice your own response, not a clinical score. A rise of even a point or two after a few cycles suggests the technique is working for you in the moment. If your rating stays flat or drops most times you try it, or if anxiety or sleep problems are showing up most nights, that is a sign to bring it up with a licensed therapist rather than to rely on the exercise alone.

4-7-8 Breathing FAQ
What is 4-7-8 breathing used for?
It is widely used to ease anxiety and to help with falling asleep. The long exhale activates the body's relaxation response, slowing heart rate and calming the mind.
How many rounds should I do?
Start with four full cycles. As the technique becomes familiar you can do it more often, but it is best to build up gradually rather than overdo it at first.
Does 4-7-8 breathing actually help sleep?
Many people find paced breathing with a long exhale calming and sleep-promoting. It is a helpful wind-down routine, though it is not a treatment for a sleep disorder.
Is anything I type saved?

Is 4-7-8 breathing safe for everyone?
It is gentle for most healthy adults, but the breath holds change oxygen and carbon dioxide levels more than normal breathing. People who are pregnant or who have a respiratory condition such as COPD or severe asthma should check with a doctor first, and anyone who feels panicky rather than calm should skip the hold and breathe slowly instead.
How is 4-7-8 breathing different from box breathing?
Both are paced breathing patterns, but 4-7-8 uses an uneven ratio built around a long exhale (4 in, 7 hold, 8 out), while box breathing uses four equal counts (4-4-4-4). 4-7-8 is often used to wind down for sleep, while box breathing is often used to steady focus under pressure.
