To investigate whether a local static magnetic field of a permanent magnet influences the amount of skin blood flow reductions induced by deep inspirations.
A single rapid and deep inspiration induces arteriolar vasoconstriction that causes a transient decrease in skin blood flow.

Setup | magnet was placed under the middle finger of one hand with south pole facing the skin |
Sham exposure | A sham exposure was conducted. |
Measurand | Value | Type | Method | Mass | Remarks |
---|---|---|---|---|---|
magnetic flux density | 85 mT | unspecified | measured | - | at the center of the magnet |
magnetic flux density | 31.5 mT | unspecified | cf. remarks | - | ± 1.1 mT; measured at the skin blood flow measurement site on the finger dorsum |
Results showed no significant difference in either vasoconstrictive responses or skin temperature due to the static magnetic field of the permanent magnet.
