When you're travelling, you're just sitting in one constant position for a long time. Throw in traffic chaos and the vehicle jerking at every stop and you'll feel irritated as well. Just sum up the psychological and the physiological stress your body goes through and what you end up with is tiredness.

Commuting is exhausting due to a combination of physical impedance, cognitive load, and psychological stress. Physically, long periods of sitting or standing in cramped spaces, such as cars or public transit, lead to muscle tension and fatigue. Cognitively, the task of driving—or even navigating complex transit transfers—requires constant vigilance, which depletes mental energy. Psychologically, the unpredictability of traffic jams or train delays creates a sense of helplessness and lack of control, which is a major driver of cortisol production. Furthermore, the "spillover effect" means that the stress of a morning commute often lingers, reducing productivity at work, while the evening commute eats into personal recovery time. In 2026, research continues to show that the lack of autonomy in one's schedule is the single most powerful predictor of commuting stress. This daily cycle of high-effort, low-reward activity effectively creates a "tax" on your well-being, leading to chronic exhaustion that can negatively impact long-term physical health and overall life satisfaction.
