Why You Crash

There are a number of reasons why you might be experiencing the afternoon slump just as there are a number of techniques you can do to snap yourself out of it when your eyelids start to drop. But if you want a significant change in energy fluctuations you need to make permanent changes to whatever it is that is acting as a trigger for your energy lows.

There are lots of ailments that can cause you to feel tired after lunch, such as allergies, insulin resistance, celiac disease or low blood sugar. But your tiredness may be due to something as simple as eating a big lunch. Digestion requires quite a lot of energy and as your stomach loads up with food extra blood rushes into your intestines from all over your body to help with the extra work. This leaves the rest of your body, including your brain somewhat deprived, with the result that you start to feel exhausted. Eat a big breakfast and opt for a smaller, light lunch.

Better Lunch Choices

There are many lunch choices that can lie behind afternoon ‘sleepies’. Avoiding meat at lunch may be a wise choice when it comes to fighting fatigue as meat is one of the hardest foods to digest. It takes two hours to digest meat compared with only thirty minutes to digest fruit. Eating a meatless lunch will place a lot less stress on your digestive system and keep that blood flowing to the brain and lungs.

Don’t forget to chew your lunch really well as saliva is loaded with enzymes that start off the digestion process. The more broken down by saliva that the food is when it reaches your stomach, the easier it will for your body to continue the process through the gut, and the less likely it will be for you to feel tired.

Gluten Intolerance

An intolerance to gluten, the protein found in some grains, can cause after-lunch fatigue in anyone suffering from coeliac disease after they have eaten foods containing gluten at lunch. But many people who have a gluten intolerance without actually having coeliac disease also benefit from removing gluten from their diet. It may be worth having this checked out if you suspect gluten intolerance is behind your tiredness.

Another reason for many people experiencing low energy level between one and four hours after eating is hypoglyceamia. Eating a lunch high in refined carbohydrates causes the blood sugars to rise rapidly, or spike, and this is followed a few hours later with a crash in blood sugars that results in fatigue, often with dizziness or shakiness. The onset will often be faster if you exercise as well. A lunch of vegetables and protein is a much better choice than refined carbohydrates. Low GI food alternatives you could look at include most fruits and vegetables, lentils, beans, hummus, quinoa, nuts and seeds. You can find a list of the GI Index rating of lots of foods here

Insulin resistance

Another sugar related cause of fatigue after eating may be insulin resistance. When excess sugar or carbohydrates are eaten the body produces more insulin, but over time your cells start to resist the insulin which leads to all sorts of health conditions, including fatigue.


One cause of afternoon tiredness that is often overlooked is caffeine. Drinking two or three cups of coffee in the morning may get you going during the morning but you pay for it later. As well as the short-lived burst of energy that caffeine provides to you, it also contributes to dehydration, a leading cause of fatigue. Think of coffee as ‘credit-card’ food (eat now, pay later) Studies show that a single cup of coffee is sufficient to keep long-haul truck drivers more alert so replace that second coffee with a large glass of water. And more importantly, don’t use caffeine as an afternoon pick-up. If you find you absolutely must have some caffeine drink green tea instead. As well as the mild dose of caffeine it contains you will receive all the other wonderful benefits green tea has to offer. Tulsi tea is another great afternoon energizer especially if adrenal fatigue is playing a part. Don’t forget that caffeine is like any drug and your body will develop a caffeine tolerance, so that where you only needed one cup originally after time you might find you need six or even ten to get the energy burst you need.


Most people working in an office will sit hunched up over their computer for most of the day and as fatigue hits in the afternoon they tend to slump down over their desk even further. Sitting up straight – shoulders back, eyes forward and lower back arched slightly -and taking some good deep breaths right down into the bottom of the lungs can re-energise you very quickly. Stand up and add a few stretches for even more benefit.

Electro Magnetic Fields

It’s worth remembering that being surrounded by EMF’s (often called electromagnetic radiation) can cause fatigue and these are always high around any electric equipment. EMF’s are especially high where there are wireless devices such as computers, wireless phones, printers, laptops, mobile phones, baby monitors, internet connections etc. so getting away from your desk or taking steps to lesson the effects will help keep you more alert.

Body Clock

If you are living in places where the sun sets during the afternoon in winter it may also be due to your own body clock. As the day starts to get dark about mid-afternoon your body temperature drops and the hormone melatonin, which makes you feel sleepy, is released. Circadian rhythms contribute to how alert you feel so open the curtains to let in the sunlight or else simply turn on more lights if it is dark outside.

Watch your sleep routine. Sleep recharges your body physically and mentally. Get yourself into a regular routine of going to bed and waking up at the same time and stick to it. You need seven to eight hours sleep a night. Studies have shown that ‘Binge Sleeping’ for one or two days a week does not counteract the sleep debt from the other nights of the week. If you don’t get enough sleep fatigue is likely to be the result. Go to bed and wake up at the same time every day, including weekends, for more energy.

Natural Strategies To Adopt

If, in spite of taking measures to address what may be contributing to your tiredness, you still find yourself falling asleep during the after lunch meeting here are some strategies that may help in the moment:

  1. Research shows that the aroma of peppermint is a natural remedy for boosting memory, focus and concentration. It is just as effective whether it is fresh leaves, essential oil or brewed tea. Enjoy a cup of peppermint tea, spray a mist of a few drops of peppermint essential oil in a cup of water about your workspace, or even place a few drops of the oil on a handkerchief to sniff, or keep a pot of mint nearby and crush a couple of leaves during the afternoon
  2. If your tiredness is related to blood sugar imbalance chewing a cinnamon stick might help as it has been shown to have a significant influence on regulating blood sugars
  3. If you are able to get away briefly a quick power nap in your car could be just enough to revive you
  4. Listening to music has been shown to raise endorphin levels which makes you feel happier. Play your favourite music or sing out loud to get you motivated again.
  5. Dehydration causes fatigue so drink some water, or even eat some foods with a high water content like lettuce or watermelon, and combine it with a walk to the water cooler to get away from your desk.
  6. Protein from nuts or yoghurt makes a good snack when you start to slump in the afternoon
  7. Get up and run up the stairs or around the block if you can. It starts the blood pumping and gives the brain a boost.
  8. Meditate – yes seriously, just a five minute meditation at your desk is enough to clear out your head and revive, refresh and recharge you.
  9. Just as animals hibernate when the weather turns cold, getting too cold can make you feel sleepy too, so throw on a jumper or turn up the heating to wake yourself up (this is usually a big help for me!)
  10. And if you are lucky enough to work from home or your workplace is a little more free you could do some exercises or hit the gym, turn the music up really loud, take a short cold shower or do some yoga
