Summary
Monitoring driver stress is crucial for road safety. This study suggests differential skin temperature, specifically truncal versus peripheral, can indicate driver stress during monotonous driving.
Area of Science:
- Physiological monitoring
- Human factors in transportation
Background:
- Prolonged monotonous driving can decrease driver awareness and increase stress, elevating accident risk.
- In-car monitoring of driver physiological status offers potential to mitigate dangerous driving situations.
Purpose of the Study:
- To investigate differential skin temperature measurement as a potential marker for driver stress levels.
- To explore the relationship between skin temperature variations and cardiovascular hemodynamics during simulated monotonous driving.
Main Methods:
- Acquisition of physiological variables including facial skin temperature (truncal and peripheral), blood pressure, cardiac output, total peripheral resistance, and normalized pulse volume.
- Subjects underwent simulated monotonous driving under controlled environmental conditions.
- Analysis of skin temperature reactivity in conjunction with cardiovascular measurements.
Main Results:
- Simulated monotonous driving led to a decrease in peripheral skin temperature (Ts) post-stress.
- This peripheral temperature drop is attributed to peripheral sympathetic activation, supported by total peripheral resistance and normalized pulse volume data.
- Truncal skin temperature remained unaffected by the driving stress.
Conclusions:
- Differential truncal-peripheral skin temperature shows promise as an index for assessing driver stress.
- This finding supports the development of in-car systems for monitoring driver physiological status to enhance road safety.

01:26Exercise Stress Test
Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

01:14Temperature Measurement Sites
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
