This document discusses strategies to avoid afternoon sleepiness after lunch. It recommends saving complex tasks for morning or early afternoon to avoid the post-lunch dip in alertness. Eating a small snack at 10:30-11 am and using the senses like music or aromatherapy from 1-1:30 pm can help stimulate the stress response. Proper food choices that influence gut hormones and timing meals can also help circadian rhythm and reduce crashes. Naps may help restore alertness for habitual and non-habitual nappers, but timing is important. The document provides an overview of sleep cycles and food influences on sleep to help optimize performance throughout the day.
