Sleep & Stress

Busy days, mental overload, and constant screen time make it harder than ever to fall asleep peacefully. The result? Weakened sleep quality and, in turn, lower stress resilience. A vicious cycle indeed.

Stress affects sleep…
Stress stimulates the nervous system and increases cortisol production — the “alertness hormone.” When cortisol levels are too high, the body struggles to “switch off,” making it harder to fall asleep and disrupting sleep cycles. The result? Restless nights, frequent awakenings, persistent fatigue.

…and poor sleep increases stress
Lack of quality sleep lowers emotional regulation and makes the brain more reactive to negative stimuli. Irritability rises, focus drops, and daily mental load becomes harder to manage. The less we sleep, the more vulnerable we are to stress.
