The 3 P.M. Energy Crash: Why It Happens and How to Keep Energy Steady

Beat the afternoon slump without reaching for sugar.

Quick answer

The afternoon energy crash is caused by a mix of factors: a natural dip in the body clock in early afternoon, a lunch high in refined carbohydrates that causes a blood-sugar spike and drop, poor sleep, dehydration and sitting for long periods. To keep energy steady, eat a lunch with protein, fiber and healthy fats, drink water, take a short walk after eating, get daylight, limit sugary snacks and protect your night-time sleep.

Key takeaways

That mid-afternoon wall is one of the most common energy complaints. Here's what's going on and how to get past it.

Why the crash happens

Body clock

Alertness naturally dips in the early afternoon as part of the circadian rhythm.

Blood-sugar swings

A lunch heavy in refined carbs can spike glucose, followed by a drop that leaves you tired and craving sugar.

Lifestyle

Short sleep, dehydration and long periods of sitting make the slump worse.
