Wake up at 6am, squeeze onto a packed train, power through a nine-hour workday, then push yourself through a gym session before collapsing into bed and doing it all again. For many of us, the pressure to keep achieving never really switches off and while you might feel like you’re coping, your body often spots the cracks far earlier than you do.
According to cancer and immunology expert Dr Atul K. Tandon, those early cues are easier to miss than you’d think.
As the Founder and President of NeoBiotechnologies, he’s seen how subtle physical and emotional changes can signal rising stress long before full burnout takes hold.
“Our bodies whisper long before they shout,” he explains. “By paying attention to small shifts like ongoing fatigue or changes in mood, we can make thoughtful adjustments and ease the pressure before it becomes something more serious. It’s not about diagnosing illness, but about building awareness of how we’re really doing.”
Here, Dr Tandon outlines the key signs that you may be pushing yourself too hard — and what they might be trying to tell you.
1. Persistent fatigue
Persistent fatigue often extends beyond normal tiredness, stubbornly remaining even after a good night’s sleep. Unlike the usual post-exercise or end-of-day exhaustion, this fatigue suggests the body is working overtime to keep stress at bay. Noticing when rest stops feeling restorative may help people recognise when they’re running on empty. Gentle lifestyle adjustments—such as regular breaks, mindfulness exercises, and balanced nutrition—may support overall energy levels.
Top tip: Keep a sleep diary for a week to spot patterns linked to fatigue.
2. Disrupted sleep
Changes in sleep patterns, such as difficulty nodding off or restless nights, often indicate stress hormones disrupting the body’s circadian rhythm. These disturbances can be a sign of heightened alertness. Calming evening routines, reduced screen time, and relaxation techniques may help support more consistent sleep patterns.

3. Mood and focus shifts
Unexplained irritability, lack of concentration, or dwindling motivation can signal mental overload or emotional strain. These shifts highlight the importance of granting the brain reprieve from constant demands. Stepping away from tasks, spending time outdoors, or limiting digital noise may help restore mental clarity.
Top tip: Set an hourly reminder to take a short break.
4. Digestive turmoil
When stress levels rise, the gut often reflects it through symptoms like bloating, appetite changes, or mild discomfort. These signs highlight the close connection between the brain and digestive system. Supporting digestion through hydration, slower eating, and balanced meals may help ease discomfort. A diet rich in fibre and probiotics can also support general gut health.
Top tip: A light herbal tea after meals can offer a calming moment of routine.
5. Minor aches and recovery delays
Frequent minor aches or sluggish recovery after exertion may reflect chronic tension within muscles and joints. Increased stress often keeps the body in a heightened state, contributing to physical strain. Gentle movement such as stretching, yoga, or walking may help improve circulation and ease tension. Ensuring adequate rest and hydration can also support recovery.
Top tip: Epsom salt baths can feel soothing after exercise thanks to their magnesium content.
