Breathe 4-7-8 ×5 to lower stress and heart rate
Why it matters
When we’re stressed or tired, our breathing becomes shallow and fast. The 4‑7‑8 technique slows your breathing rhythm, activating the vagus nerve and lowering stress levels. Research shows that controlled breathing increases heart rate variability (HRV), which is linked to relaxation and better sleep quality
How to do it
- Inhale through your nose for 4 seconds
- Hold your breath for 7 seconds
- Slowly exhale through your mouth for 8 seconds
- Repeat the cycle 5 times
- It’s best to practice during a short afternoon break
Science snap
Just 5 cycles of 4‑7‑8 breathing can lower heart rate and boost HRV—a marker of relaxation

Mechanism & Key fact
Slow, controlled breathing triggers the vagus nerve, part of the parasympathetic nervous system, which slows heart rate, reduces blood pressure, and lowers cortisol levels associated with stress. Practicing techniques like the 4‑7‑8 breath pattern—inhale for 4 seconds, hold for 7, exhale for 8—creates a rhythmic pattern that signals the brain to relax. Research shows that completing just 5 cycles of 4‑7‑8 breathing can increase heart rate variability (HRV) by up to 20%, a marker of nervous system flexibility and resilience. Higher HRV is linked to better sleep quality, reduced anxiety, and improved overall well-being
