The Science of Box Breathing (Navy SEAL Technique)
Box breathing, also known as four-square breathing, is a powerful stress management technique utilized by elite tactical units like the Navy SEALs. The pattern involves a 4-second inhale, 4-second hold, 4-second exhale, and 4-second hold. It helps regulate the autonomic nervous system, rapidly reducing stress, lowering heart rate, and improving deep concentration.
The 4-7-8 Breathing Technique for Sleep
Pioneered by Dr. Andrew Weil and based on ancient pranayama techniques, the 4-7-8 method is a natural tranquilizer for the nervous system. The rhythm consists of a 4-second inhale through the nose, a 7-second breath hold, and an 8-second exhale through the mouth. It is highly effective for combating insomnia, reducing anxiety, and managing cravings.
