About two to three hours. The duration of 5D magnetic quantum energy is generally about 2 to 3 hours, because the magnetic field has the best effect on human body during this time. During this period, the magnetic field can effectively adjust the electromagnetic balance in the human body, promote blood circulation and metabolism, and improve human immunity. At the same time, this time period is also the most active time of the human body's own magnetic field, so the interaction with the magnetic field of 5D magnetic quantum is the best.
