A breathing technique shared by neurobiologist Dr. Andrew Huberman.

WHAT IS IT

The Physiological Sigh is a technique that was discovered by doctors in the 1930s. It has recently been brought back into the spotlight after research done at UCLA and Stamford University.

It works by reinflating tiny sacs in the lungs called alveoli, which increases oxygen intake and C02 off-gassing.

The technique also emphasizes the exhale. When we exhale, the diaphragm moves upwards which gently squeezes the heart. This causes the brain the signal the body to reduce the heart rate.

WHY DO IT

Breathing is an effective way to take control of your mind and body when you are stressed. Breathing can reset the system. 

Dr. Huberman calls the Physiological Sigh “the fastest real-time tool for stopping stress and anxiety.”

HOW TO DO IT

Take two inhales through the nose followed by an extended exhale through the mouth.

Repeat as many time you feel is needed.
