Moderate physical activity

Moderate physical activity has no effect on sleep latency in humans (B = 0.04).
“Moderate activity showed no significant association (B = 0.04, SD = 0.11, 95% CI [-0.17, 0.26]).”

Vigorous physical activity

Vigorous physical activity decreases sleep latency in humans (-0.60 second per second).
“Each additional second of vigorous activity corresponded to a 0.60 second decrease in latency (B = -0.60, SD = 0.21, p < .01, CI [-1.02, -0.18]).”

Caffeine increases sleep latency in humans.
“Caffeine typically prolonged sleep latency, reduced total sleep time and sleep efficiency, and worsened perceived sleep quality.”

Sleep latency has no effect on tau pathology in humans (β = 0.129, p = 0.664).
“when examined in an adjusted regression, the change in sleep latency was not associated with pathological outcomes (tau: β = 0.129, p = 0.664”

Sleep latency is associated with tau pathology in humans (r = 0.473, p = 0.023).
“Correlational findings indicate an association between increased sleep latency and tau pathology (r = 0.473, p = 0.023)”

Light physical activity

Light physical activity is associated with sleep latency in humans (-0.02 seconds per second).
“Light activity showed a near significant reduction of 0.02 seconds per second (B = -0.02, SD = 0.01, 95% CI [-0.05, 0.01]).”
