Key result
Finger skin temperature during a 10-minute cold water immersion test was affected by room temperature and seasonal conditions, but not by food intake.
Why the study?
Do room temperature, seasonal condition, and food intake affect finger skin temperature during a cold exposure test in healthy males?
Observational (n=20)
No
Do room temperature, seasonal condition, and food intake affect finger skin temperature during a cold exposure test in healthy males?
Room temperature and seasonal conditions significantly alter finger skin temperature during cold exposure testing, necessitating strict environmental control for accurate diagnosis of hand-arm vibration syndrome.

Standardize room temperature and note season during cold provocation testing; leaves open standardized protocols for hand-arm vibration syndrome diagnosis.
For diagnosing the hand-arm vibration syndrome, peripheral circulation and sensory tests immersing one hand in cold water at 10 degrees C for 10 min have been performed widely in Japan. The authors investigated the effects of room temperature, seasonal condition and food intake on the test results, especially finger skin temperature. Six healthy males were examined repeatedly under six different room temperatures at 10 degrees C, 15 degrees C, 20 degrees C, 22.5 degrees C, 25 degrees C and 30 degrees C. Eight healthy males were examined under room temperatures at 10 degrees C, 20 degrees C and 30 degrees C, repeatedly in winter, spring, summer and autumn. Six healthy males were examined in summer under room temperature at 22.5 degrees C repeatedly 1 hr after, 3 hr after meal and after fasting for 13 hr. The finger skin temperature was strongly affected by room temperature. The finger skin temperature was also affected by seasonal condition. No remarkable effect of food intake was observed. For estimating circulatory function of the upper extremities using the finger skin temperature, the room temperature should be strictly controlled and the effect of seasonal condition must be taken into consideration.

Harada et al. (1998) conducted an observational in Healthy (evaluating diagnostic test conditions for Hand-Arm Vibration Syndrome) (n=20). Room temperature, seasonal condition, and food intake vs. Different temperatures, seasons, and fasting states was evaluated on Finger skin temperature during cold exposure test (p=<0.01). Finger skin temperature during a 10-minute cold water immersion test was affected by room temperature and seasonal conditions, but not by food intake.
