When routines start crumbling: Doctor reveals what sleep, food and social shifts may be telling your brain
Most of us treat daily routine as something we force on ourselves, wake-up time, meal times, work hours and a fixed end to the day. But according to Dr Kunal Bahrani, Chairman and Group Director of Neurology at Yatharth Hospitals, routine does something deeper for the brain. It offers predictability.
In a recent conversation, Dr Bahrani explained that our brains are constantly processing information, responding to demands and adjusting to the world around us. Regular sleep, meals, movement and social contact create a steady rhythm against which all of this happens. When that rhythm breaks for a long stretch, he said, it is not always just a lifestyle hiccup. It can be an early clue that something needs attention.
Sleep is often the first place change shows upDr Bahrani noted that sleep is usually the earliest part of the routine to signal that something has shifted. A person may suddenly find themselves lying awake even when exhausted, waking several times at night, or getting up unusually early. Others may start sleeping far longer than before yet still wake feeling unrefreshed.
From the brain’s point of view, sleep is not simple downtime. It plays a key role in memory, attention, emotional balance and recovery. When sleep stays disrupted, the effects spill into the day. People may forget small things, lose patience more easily or struggle to focus on tasks that once felt automatic.
He was careful to add a note of caution: one bad night does not mean anything serious. Persistent patterns over time are what matter.
Appetite shifts can travel with sleep and mood changesThe same idea applies to eating, Dr Bahrani said. Appetite is shaped by a mix of brain signals, hormones, metabolism and emotions. Under stress, some people barely notice they have skipped meals and others find themselves reaching for food more often.
A lasting change in appetite becomes more meaningful when it arrives alongside shifts in sleep, energy or mood. In those cases, he advised, it is worth paying attention rather than brushing it off as “just stress.”
The “shrinking day” is another quiet warningAccording to him, one pattern that stands out is the “shrinking day.” A person’s world slowly gets smaller. The morning routine often fades, exercise drops away. Lunch is eaten at the desk. Invitations are turned down. Hobbies are left behind. Weekends begin to look exactly like weekdays.
No single change is alarming on its own. Life gets busy and people need rest. But when several familiar activities disappear at the same time, he suggested it is worth asking why. The brain does not work in separate boxes. Sleep affects concentration.
Chronic pain can colour mood. Mood can drain motivation and further disturb sleep. Neurological conditions, certain medicines and other medical factors can also alter energy, thinking or behaviour.
When a patient tells him, “I just don’t feel like myself anymore,” Dr Bahrani said he looks at the whole picture of how the person is functioning, not at one isolated symptom.
How families can notice and open a gentle conversationFamilies can take a similar approach, he advised. Instead of zeroing in on one behaviour, “You’re sleeping too much” or “You never come out anymore” look at the broader pattern. Has sleep changed? Is eating different? Is concentration harder? Have enjoyable activities stopped? Is the person pulling away from people?
Then ask, without judgement: “I’ve noticed a few things have changed lately. How have you been feeling?” The goal is not to diagnose across the dinner table. It is simply to create space for the person to talk.
If the changes last, grow stronger or start affecting work, relationships and daily life, a medical check is worthwhile. Fatigue, poor concentration, sleep problems and withdrawal can have psychological roots, but they can also appear with sleep disorders, neurological conditions, chronic pain, medication effects, nutritional gaps and other medical issues.
Dr Bahrani’s closing thought was simple. Routine is not only a productivity tool. Sleep, appetite, social contact and the ability to enjoy ordinary activities also reflect how the brain and body are coping. When several parts of the usual day begin vanishing together, the answer is not always to push harder. Pause and ask what has changed; and why. Sometimes noticing that shift early is the first step toward understanding what the brain and body are trying to say.
