A Daily Mail news report examines a new breathing technique developed by Dr. Andrew Weill designed to help you sleep.
The technique is based on pranayama, an ancient Indian practice that means ‘regulation of breath.’
The Harvard-trained doctor claims that 4-7-8 is such a powerful technique because it allows oxygen to better fill the lungs.
This extra oxygen can have a relaxing effect on the parasympathetic nervous system, which promotes a state of calmness.
During times of stress, the nervous system becomes over stimulated leading to an imbalance that can cause a lack of sleep.
As well as relaxing the parasympathetic nervous system, Dr Weil says 4-7-8 helps you feel connected to your body and distracts you from everyday thoughts that can disrupt sleep.
