Background/Objective: Apnea is the temporary stoppage of breathing, most often in reference to transient blockage of atmospheric oxygen. Apnea during temperature change has been linked to a number of disorders including hypertension, stroke, arrhythmias, cardiomyopathy, heart failure, diabetes, obesity and heart attacks. This study was aimed at investigating the effect of varied temperature at different times of the day on the duration of voluntary apnea in healthy young male subjects. Materials and Methods: A total of 60 apparently healthy young male subjects with a mean age of 23 ± 1 years, body weight of 63.2 ± 1.8 kg, and height of 169.9 ± 1.8cm who were non-smokers and not on any medication were recruited for this study. Informed consent was obtained from each participant after proper notification and information on the nature of the research, risk involved, benefits as well as confidentiality. The experimental period lasted for 4 weeks after which the data was analyzed. Measurements were recorded in the morning, afternoon and night. Results: Voluntary apnea in the morning 26.70 ± 1.30, was significantly (p=0.016) higher when compared to the afternoon period 22.43 ± 1.16. It was also observed that voluntary apnea was significantly (p=0.020) higher in the night 26.82 ± 1.44, when compared to the afternoon 22.43 ± 1.16. These results clearly show that the duration of voluntary apnea increases when temperature falls in the morning and night times of the day. This knowledge may be useful in the management of patients with sleep apnea.
