Your Commute and Your Cortisol
A stressful commute—whether it involves navigating dense traffic, jostling for space on a crowded bus, or worrying about being late—triggers the body's 'fight-or-flight' response. This floods your system with cortisol, the primary stress hormone. When
cortisol levels are high, your body enters survival mode. It diverts energy away from functions it deems non-essential, and unfortunately, optimal digestion is one of the first things to be paused. Instead of efficiently breaking down your breakfast and absorbing its nutrients, your body may struggle, leading to issues like bloating, indigestion, and poor nutrient uptake. Essentially, the stress from your journey can effectively 'cancel out' some of the nutritional benefits of the meal you just ate.
The Critical Role of Timing
The emerging science of chrononutrition suggests that when you eat is just as important as what you eat. Our bodies run on an internal clock, or circadian rhythm, which governs everything from sleepiness to metabolism. Insulin sensitivity and digestive functions are generally at their peak in the morning and early afternoon, making this the best time to consume a significant meal. However, eating a large breakfast and then immediately sitting for a prolonged period in a car or on a train can be counterproductive. This sedentary state, especially when combined with stress, tells your body to store energy rather than use it. Eating late at night is known to be disruptive, but the same logic applies to a breakfast that isn't timed well with your morning activity. A meal eaten in a stressed, rushed state, followed by inactivity, is not metabolised as efficiently.
The 'Deskfast' Dilemma
For many, the solution to the morning rush is to eat on the go or have a 'deskfast' (breakfast at your desk) upon arrival. While this might seem efficient, eating while distracted—whether driving, walking, or checking emails—is a form of mindless eating. Mindful eating, in contrast, involves paying full attention to your food. Taking just a few minutes to eat slowly, without distractions, allows your body to properly register feelings of fullness and kickstarts the digestive process more effectively. When you chew thoroughly and eat at a relaxed pace, your digestive system is better prepared to handle the food, leading to improved nutrient absorption and greater satisfaction from your meal. Scarfing down a meal while your mind is elsewhere means you miss these crucial cues.
Optimise Your Morning Meal and Journey
Reclaiming the value of your breakfast doesn't necessarily mean a complete life overhaul. Small, strategic shifts can make a significant difference. If your morning commute is invariably stressful, consider waking up just 15-20 minutes earlier to eat in a calm environment before you leave. This separates the act of eating from the stress of travelling. Alternatively, if you can't stomach food early, pack a portable but balanced breakfast to eat once you’ve reached your destination and had a moment to settle. Options like overnight oats, a protein-rich smoothie, or pre-made egg cups are excellent choices. If your commute involves walking, time your breakfast to fuel that activity. A lighter meal beforehand can provide the energy you need without weighing you down. The goal is to create a buffer between the stress of commuting and the process of nourishing your body.
