Are you too dependent on your smartwatch? UAE experts explain the warning signs

You know the drill. You wake up in the morning, and immediately check your watch, attempt to analyse the sleep score, scan the recovery levels. Yikes, the stress readings are high.

And you haven't worked out much, this week.

Panic, panic. You're doing enough, but it's not enough. You're reading between the numbers on the smartwatch.

The numbers have decided how you feel. And what's a life decided by numbers?

Well, as wearable technology becomes more sophisticated, experts warn that the same devices designed to improve health awareness can also create a new kind of anxiety: one where people trust algorithms more than their own bodies.

When health data stops being a tool and starts controlling you

Nargiza Noimann-Zander, founder of X-technology, says the problem is not tracking itself, but the relationship people develop with the data. “Tracking health data is helpful as long as it supports more conscious decisions. The problem begins when the numbers start controlling a person’s emotional state,” she explains.

The warning sign, she says, appears when people begin relying on their devices before paying attention to how they actually feel.

“If someone wakes up and immediately checks their data before noticing how they actually feel, the device gradually becomes an external judge of their wellbeing. At that point, the data stops being a tool and starts becoming a source of anxiety.”

This pattern is especially common among people who struggle with anxiety, perfectionism or a strong desire for control. A score that falls short of an 'ideal' number can feel like a warning sign, even when there is no actual health concern.

Why we trust a number more than our own body

A major reason health trackers have become so influential is that numbers feel objective. Sleep quality, stress levels and readiness scores appear scientific, and because they come from technology, many users assume they must be more accurate than their own sensations. “The human brain tends to see digital data as more objective than subjective experience,” Noimann-Zander says.

“We live in a culture of measurement, where numbers often appear more reliable than personal sensations.”

However, there is a catch. Modern algorithms can create an illusion of precision. A recovery score of 62 per cent, for example, may look like a medical assessment, but many wearable metrics are based on statistical models and probability rather than a complete picture of a person’s health.

“The paradox is that the body contains far more information about its own state than any wearable device. But increasingly, people are handing over the right to interpret their condition to algorithms,” she adds.

The 'algorithmic interpretation' of your body

Constant feedback from devices can also change the way people experience normal bodily sensations.

Feeling tired after a stressful day is normal. A restless night happens. Heart rate changes throughout the day. However, when a device labels these experiences as 'high stress' or 'poor recovery', people may begin viewing ordinary fluctuations as problems.

“When people receive constant data about their state, the brain begins to interpret bodily sensations through the lens of the device,” Noimann-Zander says.

“Over time, this can create what I would call an ‘algorithmic interpretation of the body.’ A person no longer experiences the body directly, but through a digital filter.”

This can lead people to question themselves: Am I actually tired, or did my watch tell me I am?

How a bad sleep score can shape your entire day

A low recovery score first thing in the morning may seem harmless, but it can influence mood, confidence and behaviour.

Noimann-Zander says it can create a self-fulfilling argument. “If someone sees a low recovery score immediately after waking up, they may begin to expect low productivity, fatigue, or poor wellbeing. Those expectations can influence attention, mood and behaviour throughout the day.”

And so, someone might avoid a workout, postpone an important task or assume they cannot perform well, even if their actual energy levels are adequate.

Smartwatches are useful, but they are not doctors

While the psychological impact of health tracking is important, doctors also warn against treating wearable data as a medical diagnosis. Dr Jan Niclas Strickling, Consultant Cardiology at Medcare Al Safa, says smartwatches have made people more aware of their health, which can be a positive development.

“They can provide useful insights into heart rate, activity levels, sleep patterns and, in some cases, even alert users to potential irregularities that warrant medical attention,” he says.

However, these devices remain screening tools, and not diagnostic machines.

“A single reading taken out of context can be misleading,” Dr Strickling explains. Moreover, factors including movement, poor sensor contact, dehydration, stress, caffeine intake and environmental conditions can affect readings.

The greatest risk rises, when people either become unnecessarily anxious over isolated readings or, conversely, delay seeking medical care because their watch appears to show everything is normal.

A smartwatch can raise a question, he says, but it cannot replace a doctor’s assessment. “Diagnosis involves far more than numbers on a screen. It requires a thorough medical history, physical examination and, where appropriate, further investigations.”

What health data is actually worth tracking?

For most healthy adults, Dr Strickling says useful areas to monitor include:

• Physical activity levels

• Exercise patterns

• Sleep trends

• Long-term lifestyle changes

People with specific conditions, such as hypertension, diabetes or heart conditions, may benefit from tracking additional information, such as blood pressure, glucose or heart rhythm, under medical guidance.

However, obsessing over daily fluctuations can do more harm than good.

“Day-to-day changes in heart rate, sleep scores, calorie estimates or stress measurements are often completely normal,” Dr Strickling says.

Instead of chasing perfect numbers, people should focus on patterns.

“Good health is about overall wellbeing, not perfect data.”

Signs your health tracker is increasing anxiety

A wearable device may no longer be helping if:

• You feel anxious when you cannot check your data

• Your mood depends heavily on your scores

• You ignore how you feel because the device says something different

• You feel guilty about “bad” readings

• You avoid activities because of low recovery scores

• You repeatedly check metrics throughout the day

Noimann-Zander says the biggest warning sign is when technology reduces confidence in your own body. The real self-awareness occurs when technology supports the body's internal signals, and not when it replaces them.

How to use health trackers without becoming controlled by them

Experts suggest a healthier approach:

Look for trends, not single numbers

One poor night of sleep or one unusual reading rarely tells the whole story.

Check your body before checking your device

Ask yourself: How do I feel today? Am I tired? Energised? Stressed?

Use data as information, not judgment

A score is a clue — not a verdict.

Know when symptoms matter more than numbers

Chest pain, breathlessness, fainting, severe dizziness or persistent fatigue should always be taken seriously, even if a wearable shows normal readings.

Give yourself permission to ignore the score

Health is not a competition. A tracker should help you understand yourself better, not make you feel like you are constantly failing.
