At 3 p.m., do your eyelids grow heavy, your mind foggy, and your focus plummet? Are you zoning out in meetings and instinctively reaching for coffee, sugary drinks, or snacks, as if only external stimulants can revive your energy? Nutritionist Jen-Tzu Chan from Major Health warns that if this happens daily, it may not just be fatigue—it could be your body signaling an energy imbalance.
The Afternoon Energy Crash: A Common Struggle for Office Workers
Jen-Tzu Chan, a nutritionist at Major Health, explains that humans naturally experience physiological fluctuations, with alertness dipping in the afternoon. Occasional tiredness is normal. However, she observes that afternoon fatigue has become more pronounced and widespread, especially among younger office workers.
First Cause: Blood Sugar Spikes and Crashes from Post-Lunch Snacks and Drinks
Many office workers eat lunchboxes, noodles, or fried foods, then follow up with sugary afternoon snacks, bubble tea, or desserts. This combination causes rapid blood sugar spikes followed by sharp drops, leading to fatigue, poor concentration, and increased hunger. This cycle drives people to consume more sweets or caffeine for a temporary boost.
Second Cause: Sleep Deprivation or Poor Sleep Quality
Many people stay up late for work, binge-watching, or scrolling on phones, leading to insufficient sleep. Others sleep six to seven hours but still feel tired—often due to poor sleep quality. Frequent nighttime awakenings, difficulty falling asleep, snoring, light or dream-filled sleep, or sleep apnea can prevent the body from fully repairing itself, weakening daytime energy regulation and amplifying afternoon fatigue.
Third Cause: Missing the 'Energy-Producing Ingredients'
Beyond sleep and diet, nutrient deficiencies are a key cause of fatigue. The body needs various nutrients—iron, vitamin B12, folate, vitamin D—to produce energy. Women may lose iron during menstruation, while men often suffer from unbalanced diets, leading to deficiencies in these essential 'fuel sources.' Without them, the body can't generate energy effectively, even after rest.
Fourth Cause: Thinking You're Working, But Your Body Is Constantly Draining
Many people start their day in a state of high tension. Work messages, meetings, performance pressure, and life responsibilities keep the autonomic nervous system in a constant high-load mode. This continuous stress depletes the body's repair resources. When the natural afternoon energy dip occurs, fatigue is dramatically amplified.
Fifth Cause: Changes in Metabolic Function
Clinically, many young people report chronic fatigue and low energy. Further checks often reveal metabolic issues such as insulin resistance, abnormal blood sugar, high body fat, or increased visceral fat. These conditions impair the body's ability to produce and use energy efficiently, leading to a constant 'low battery' state.
"Occasional tiredness is part of natural rhythms, but if you feel like your power plug has been pulled and rest doesn't help much, it's not just work fatigue—you should be alert," warns the nutritionist.
Finally, Jen-Tzu Chan urges people to stop relying solely on caffeine and instead adjust their energy management. Suggestions include:
- Increase protein and vegetables at lunch - Avoid excessive sugary drinks - Exercise regularly - Improve sleep quality - Manage stress effectively - Regularly check blood sugar, metabolism, nutrient levels, and other health indicators
By doing so, individuals can identify the root causes of fatigue and achieve sustainable energy balance.
