Cognitive performance and mood during respirator wear and exercise

Area of Science:

• Occupational Health
• Human Physiology
• Cognitive Science

Background:

• Respirator use is common in various occupational settings.
• Potential impacts of respirator wear on cognitive function and mood require investigation.
• Low-intensity physical activity may interact with respirator-induced physiological stress.

Purpose of the Study:

• To evaluate the effects of respirator use with varying inspiratory resistance on cognitive performance.
• To assess the impact of respirator wear during low-intensity exercise on mood states.
• To determine if respirator stress negatively affects decision-making and mood.

Main Methods:

• Eight subjects performed 60-minute treadmill walks under three conditions: no respirator, high-resistance respirator, and low-resistance respirator.
• Cognitive tasks included choice reaction, serial addition/subtraction, logical reasoning, and serial reaction.
• Mood was assessed using a 36-adjective questionnaire measuring activity, anger, depression, fear, happiness, and fatigue.

Main Results:

• No significant differences were observed in cognitive task accuracy, speed, or throughput across conditions.
• Respirator wear and low-intensity exercise did not significantly affect any of the six measured mood factors.
• Neither high nor low inspiratory resistance respirators altered cognitive or mood outcomes.

Conclusions:

• Combined respirator wear and low-intensity physical activity do not adversely affect cognitive performance.
• Respirator use during light work does not appear to negatively impact mood states.
• These findings suggest that standard respirators are safe for cognitive and emotional function during low-level exertion.
