Chronic stress can keep cortisol levels elevated by up to 20–30% above normal baseline levels throughout the day
Stress slips into our daily routine without informing us. The late-night scroll, the skipped breakfast, the extra cup of coffee “just to get through the day.” Overtime, these things hardly seem to keep cortisol in check. More often than not we blame cortisol to be the villain. But In fact it plays a role in helping us wake up, stay alert and respond to daily activities. The issue arises when cortisol levels remain high for prolonged periods, pushing the body into a state of chronic stress.
Cortisol levels are typically 50–60% higher in the morning to help you wake up and gradually decline by evening (Endocrine Society, 2025–2026). “Cortisol follows a natural rhythm—it peaks in the morning to help you wake up and gradually declines by night,” explains Dr Aarti Menon, an endocrinologist based in Mumbai. “But when lifestyle habits disrupt this rhythm, the body struggles to regulate stress effectively. Over time, this can impact metabolism, sleep quality and hormonal balance.”
The Scroll That Steals Your Sleep
Skipping meals is another stressor that most of us don’t realise. It puts our body into a flight response, where the shock is unfathomable. Our bodies require nourishment when it doesn’t get it, cortisol rises to maintain blood sugar levels, leaving you feeling jittery, fatigued or irritable by mid-morning. Similarly doom scrolling is one of the overlooked triggers. The blue light from screens interferes with melatonin production, which keeps the brain alert when it should be winding down. The result? Poor sleep, delayed recovery, and a cortisol spike.
A cup or two of coffee can enhance our focus, but on an empty stomach it can overstimulate the adrenal system. Pair this with a sedentary yet mentally demanding lifestyle, and you have a recipe for persistent stress.
Rhea Shah, (24) marketing executive was constantly tired, irritable. “It wasn’t until I spoke to a nutritionist that I realised my body was stressed, not healthy.” Research shows that some of our most “normal” habits can quietly push cortisol levels higher than we realise.
The Blurred Line
Information online can be misleading, and some “healthy” habits can backfire. Rigid dieting and obsessively tracking calories or steps can lead to overexertion and trigger a stress response, blurring the line between discipline and distress, especially among Gen Z and millennials.“I don’t have a ‘clock-out’ time,” says homemaker Neha Kulkarni (42). “From the moment I wake up to when I go to bed, I’m thinking about meals, chores, everyone else’s schedules. Even when I sit down, my mind doesn’t stop. I didn’t realise this was stress because it felt like just part of life.” This invisible labour, combined with a lack of rest, can keep the nervous system in a prolonged state of alertness.
While medical tests can confirm cortisol imbalances, the body often sends subtle signs like: Persistent fatigue despite adequate sleep. Difficulty falling or staying asleep. Increased cravings, especially for sugar or salt, Mood swings, anxiety or irritability, Brain fog and lack of focus.
Resetting the Rhythm
The best part is that you don’t need a full 360 to bring change. It’s the minor habits that need to go. Starting with sleep, setting a routine bedtime. Limiting screen use an hour before bed and sticking to the boundaries set.
Eating well balanced meals stabilises blood sugar levels and reduces cortisol spikes. Including protein, healthy fats and fibre in your breakfast can set a more stable tone for the day. Movement matters but so does the recovery, incorporating rest days between workouts is a healthy habit, it gives your body a break. If you are still persistent on moving your body then stretching or low-impact activities like walking or yoga can help.
Chronic stress doesn’t always feel dramatic—it often feels normal. Building moments of “me time” into your daily life is most imperative, whether it's a short walk or a mindful soul healing class. Understanding cortisol isn’t about eliminating stress altogether—that’s neither possible nor healthy. Because sometimes, it’s not the big life events that wear us down—it’s the small, everyday habits we never thought to question.
