DOES A SHORT WALK AFTER LUNCH IMPROVE AFTERNOON ALERTNESS?

CONSENSUS

Yes

EVIDENCE TIER

Observational

SHORT ANSWER

Light activity can counter post-meal sleepiness and improve perceived energy and attention in many people.

TOPIC BACKGROUND

Short, easy walks are a common way to break up sedentary time during workdays. A few minutes of movement can change the sensory input, posture, and lighting compared with staying seated indoors. Some people prefer outdoor routes for fresh air and natural light, while others opt for indoor hallways when weather or time is tight.

Walk breaks are flexible: they can be scheduled after meals, between meetings, or whenever a task switch is needed. Footwear, route safety, and step count goals are practical considerations. Because walking requires minimal equipment and planning, it is often adopted as a low-barrier habit.

MECHANISM SUMMARY

Low-intensity movement increases circulation and reduces postprandial sluggishness.
