Afternoon Crash: What Causes It and What Helps?

Between 1:00 p.m. and 4:00 p.m., there is an energy "crash" which can also cause loss of focus. This is real, it's definitely not just you. There are many others who experience the same thing. Part of why this happens is because it is part of how your body functions throughout the day. However, much of the reason this happens is due to several of your own daily habits that you could potentially change. These habits include: light intake, physical activity, water intake, timing of lunch, and when you consume caffeine.Β 

Here's what's going on, and what helps.Β 

What is an afternoon crash?Β 

Afternoon decline (or 3 p.m. wall) is a natural drop in mental focus and energy levels that can occur during the late morning/early afternoon hours. According to Cleveland Clinic, an individual's biological clock drops naturally in the early afternoon.Β 

In fact, the early-afternoon fatigue doesn't just happen during lunchtime. Research indicates that this "slump" occurs regardless of whether or not a person has eaten. As a result, the early-afternoon slump seems to be relatively predictable, because it appears at about the same time every day - regardless of whether or not a person has consumed food.Β 

A drop is different from a crash. The amount of damage depends greatly upon how well the other parts of your day go.Β 

Why do I crash in the afternoon?Β 

The reason for the slump is twofold. One aspect is that your body has an internal clock (rhythm) and the early afternoon is a time of reduced activity. What you had for lunch does not completely account for the reduction in activity. Because of this, you will generally experience a decrease in activity during the early afternoon.Β 

Your habits (the second layer) determine just how far down you will go when things get bad. There are five key habits that affect this the most, and each is described below:Β 

  • Hours indoors, away from daylightΒ Β 

  • Sitting for long stretchesΒ 

  • Not drinking enough waterΒ 

  • A big, heavy lunchΒ 

  • Caffeine at the wrong timeΒ 

You can't move the clock. You can change most of the rest. Β 

What helps with an afternoon crash?Β 

Five habits, none of them complicated. You don't need all five every day. Picking one or two is a good start.Β 

Does getting outside actually help?Β 

Trying to get as much daylight-like light as possible throughout the day is probably one of the simplest things you could possibly do. In fact, according to Harvard Health, exposure to bright light during the day may help you feel more energized, positive, focused, and responsive.Β 

Take your lunch outside, answer calls while walking, or position your desk near a window. Integrate it into your daily routine instead of flipping a switch at 3 p.m.Β 

Does a short walk make a difference?Β 

And yes, you don't necessarily need to go to the gym. The Cleveland Clinic recommends a 10-30 minute walk after each meal. Researchers at the University of Georgia found that individuals who engaged in low intensity exercise had approximately 20% more energy than those who did not exercise. Low intensity exercise provided nearly the same benefits as moderate intensity exercise.Β 

That may mean a short walk around the building after eating, taking the stairs rather than the elevator, or standing while making your next phone call at work.Β 

Does drinking water help?Β 

It's worth giving a shot. Researchers at the University of Connecticut have discovered that being even a little dehydrated can influence your mood, energy levels, and ability to process thought clearly. When participants in one of their studies were dehydrated, they perceived their task as being more difficult than if they were adequately hydrated.Β 

The habit takes little effort. Have a reusable water bottle at your desk to use throughout the morning rather than when you are dehydrated.Β 

What kind of lunch makes the afternoon easier?Β 

Smaller and lighter. According to the Cleveland Clinic, the post-meal slump will be greater when you eat more food with more calories; therefore, the clinic suggests eating smaller and healthier (balanced) meals that have a base of protein and fiber.Β 

In essence, it is a plate of food consisting of protein, vegetables and whole grains rather than a large bowl of pasta. Alternately, you may reduce your current serving size in half and include a small snack prior to and following the meal. Additionally, try to avoid eating at your desk so that your lunch period can be considered an actual break. Β 

When should I stop having caffeine?Β 

Caffeine's effects last about four to six hours earlier than what most individuals believe. Thus, if you drink a cup of coffee around 3:00 p.m., the caffeine will remain in your system until dinner time. It's important to remember that when you consume caffeine, as well as the quantity of caffeine consumed, are equally important.Β 

One easy way to stay energized throughout the day is to limit coffee consumption to the morning hours and first half of the afternoon. If you grab a second cup of joe after you begin feeling tired, you areΒ essentially delaying that sluggishness until later in the evening.Β 

Additionally, you should know what your maximum intake of caffeine per day can be. According to the FDA, most adult individuals who are healthy can safely consume up to 400 mg of caffeine on an average daily basis; however, there is a wide range of sensitivity levels among individuals.Β 

What does an easier afternoon look like, hour by hour?Β 

Put the five habits on a clock and they take a few minutes each. Here's one way to lay them out:Β 

TimeΒ 

Try thisΒ 

12–1 p.m.Β 

A lighter lunch, away from your desk. Then a 10-minute walk.Β 

1–2 p.m.Β 

Refill your water bottle. Get some daylight, or sit near a window.Β 

2–3 p.m.Β 

Stand up, take the stairs, or switch to a task that gets you moving.Β 

3 p.m. onΒ 

Skip the extra coffee. Water and a short break instead.Β 


The point is to have a plan before the slump arrives, not to improvise onceΒ it's here.Β 

What if the slump hits anyway?Β 

On some days it will. Select a single action to perform immediately (e.g., take five minutes to go outside; drink a whole glass of water; walk once around the room; or change tasks to something less challenging for 30 minutes). Don't wait for your late-day coffee. It can wait until tonight.Β 

So begin tomorrow with a little extra time. When you set up everything the previous night, it allows you to make one less decision during the course of your morning.Β 

Frequently asked questionsΒ 

Is the afternoon slump normal?Β 

Yes, according to Cleveland Clinic, there is an natural drop in your body's "internal clock" in the early afternoon, and studies show that this dip occurs regardless of whether you eat or do not eat lunch. Habits such as eating a large lunch and/or not drinking enough fluid can cause the dip to be more apparent.Β 

What is a 3 p.m. crash?Β 

The "afternoon crash" is also known as a decrease in energy levels and ability to concentrate which typically occurs during the hours of 1 to 4 p.m.Β 

Why does it happen at the same time every day?Β 

Because it is based upon how you live your life each day and not simply based upon what you eat during your lunch hour. The early afternoon "slump" can be attributed to more than just the food that was consumed at noon. Therefore, this slump occurs at approximately the same time each day.Β 

Does what I eat at lunch matter?Β 

Yes. According to Cleveland Clinic, larger, heavier meals for lunch will cause you to experience a bigger "slump" than if you had eaten a smaller meal. You can help avoid experiencing a major slump by eating a smaller, balanced meal that contains some protein, vegetables and whole grains.Β 

When should I stop having caffeine?Β 

The effects of caffeine, as reported by the NIH's MedlinePlus, are active for approximately 4-6 hours. Therefore, try to consume your daily dose of caffeine prior to mid-day (early afternoon) so that the effects will have diminished by the time you go to bed.Β
