The effects of presleep activity on all-night sleep.

Psychophysiology 1976 Nov; 13(6):536-540
The effects of light dynamic exercise, a progressive relaxation procedure, and a boring monotonous vigilance task on the uninterrupted sleep of normal subjects were investigated during 4 consecutive nights. Nine male undergraduate college students completed a sleep habit questionnaire, and were physiologically monitored during their presleep activities and during 7.5 hours of sleep. The latency of sleep onset was shortest after relaxation and longest after exercise. Presleep heart rate and muscle tension differences as measured by an electromyograph were not related to sleep onset. Analyses of sleep stages indicated that the presleep activities produced no significant differences except in Rapid Eye Movement latency after exercise. No significant differences were observed between each presleep activity condition and normative data. The authors conclude that activity immediately before bed may effect changes in sleep latency without any substantial disturbances to the normal sleep pattern.
