Effect of zero magnetic field on cardiovascular system and microcirculation

Area of Science:

• Cardiovascular Physiology
• Biophysics
• Space Medicine

Background:

• Earth's magnetic field is a constant environmental factor influencing biological systems.
• Understanding human physiological responses to altered magnetic field conditions is vital for space exploration.
• Previous research has not fully elucidated the cardiovascular effects of complete magnetic field absence.

Purpose of the Study:

• To investigate the physiological effects of zero magnetic field exposure on the cardiovascular system of healthy adults.
• To quantify changes in capillary blood flow, blood pressure, and electrocardiogram (ECG) parameters.
• To provide data relevant to the health challenges of long-duration space missions.

Main Methods:

• Utilized the "ARFA" facility for controlled generation of zero magnetic field conditions.
• Monitored cardiovascular parameters including capillary blood flow, blood pressure, and ECG.
• Employed a comparative study design with subjects exposed to both zero magnetic field and sham conditions.

Main Results:

• A 60-minute exposure to zero magnetic field demonstrated significant effects on the cardiovascular system.
• Measurable alterations were observed in microcirculation parameters.
• Cardiovascular system responses indicated sensitivity to the absence of magnetic fields.

Conclusions:

• Zero magnetic field conditions induce notable changes in cardiovascular function and microcirculation.
• These findings have implications for astronaut health during interplanetary missions.
• Further research into long-term hypo-magnetic exposure is warranted.
