If the amount of decrease in brightness in a specific area of the test subject 100 is small, it can be interpreted that sweating occurs small in that specific area, and the amount of sweating can be converted to a relatively small value. If the amount of reduction in brightness in a specific area of the subject 100 is large, it can be interpreted that sweating occurs largely in that area, and the amount of sweating can be converted to a relatively large value. If the amount of reduction in brightness in a specific area of the test subject 100 is 0, it can be interpreted that sweating has not occurred in that specific area, and the amount of sweating can be converted to 0.

- the covering member 20 includes an antiperspirant coating layer 21 of 0.03-0.08mm and a fiber layer 22 of 0.20-0.40mm. It is desirable to be configured. If the antiperspirant coating layer 21 is less than 0.03mm, the degree of discoloration and absorption of sweat due to sweating is insufficient, and thus the amount of sweating measured using the change in brightness is inaccurate. If the antiperspirant coating layer 21 exceeds 0.08mm, the air permeability of the fiber layer is too low, and the covering member 20 seals the sweat glands of the subject 100, thereby distorting the sweating pattern, and the amount of sweat measured using the change in brightness.
- the covering member 20 can seal the sweat glands of the subject 100, and because the thickness is thick, there is a problem that the absorption of sweat due to sweating is not sufficiently transferred to the sweating agent coating layer, so the pattern of sweating is distorted.

- the meaning of the secondary sweating reference point corresponds to normal and sufficient sweating when a sweating amount of 2.45 ⁇ l/cm 2 or more is shown in the human body, and there is no major abnormality in the body part and the primary sweating reference point in the future. Since there is no possibility of falling below this, it means that there is no possibility of abnormalities in the human body in the future. However, it is possible to interpret that a body part that is more than 2.45 ⁇ l/cm2 but less than the third sweating reference point, 3.00 ⁇ l/cm2, is in an imbalanced state compared to other parts of the body showing the amount of sweating above the third sweating control point. Do.
- the meaning of the third perspiration reference point in the present invention corresponds to normal, sufficient and balanced sweating when the amount of perspiration is 3.00 ⁇ l/cm2 or more in the body part, and that there is no major abnormality in the body part and in the future 1 Since there is no possibility of falling below the initial threshold, there is no possibility of abnormalities occurring in the body parts in the future, and it means that the sweating balance of the whole body is sufficiently established.
- the primary sweating reference point is 1.95 ⁇ l/cm2 or more in both the left and right of the specific area, the left specific area is 1.95 ⁇ l/cm2 or more, but the sweating amount is less than 2.45 ⁇ l/cm2, the secondary sweating reference point, and the right specific area is 2.45 If it is more than ⁇ l/cm2 but less than the third perspiration reference point of 3.00 ⁇ l/cm2, the specific areas on the left and right are in an unbalanced state, so it is necessary to consider the overall balance of the human body, and the specific areas on the left are currently normal sweating However, there is a possibility that it may fall below the primary sweating reference point in the future, and there is a possibility that abnormalities may occur in the human body in the future.
- the amount of sweating of the human body as a whole appears almost in a normal state. If the specific area is more than 2.45 ⁇ l/cm2 but is less than the third sweating reference point, 3.00 ⁇ l/cm2, and the other parts are above the third sweating reference point, 3.00 ⁇ l/cm2, there is an imbalance in the specific area of the human body. It is in a state and may require consideration and treatment of the overall human balance for prevention.
