A different look at shifting baseline syndrome

Have you ever become so used to being busy that you no longer notice how tired you are? Or become so accustomed to stress that it simply felt like part of everyday life?

Many of us adapt remarkably well to the conditions around us. We adjust to increasing responsibilities, demanding workloads, family pressures, financial concerns, and the constant stream of information that modern life brings. In many ways, this ability to adapt is one of humanity's greatest strengths.

Yet adaptation has a hidden side. Sometimes we become so accustomed to a condition that we stop noticing it altogether.

This idea is reflected in a concept known as Shifting Baseline Syndrome. Originally developed by marine biologist Daniel Pauly, the theory describes how people gradually come to accept changing environmental conditions as normal. As each generation inherits a slightly altered version of the world, it becomes increasingly difficult to recognise what has been lost.

While the concept was first used to understand environmental change, it raises an interesting question about human well-being.

What happens when stress becomes normal?

Human beings adapt to almost everything.

We adapt to long working hours, busy schedules, poor sleep, constant notifications, relationship difficulties, and ongoing uncertainty. Rarely do we wake up one morning and decide that exhaustion is acceptable. Instead, we adjust one small step at a time. We stay a little later at work. We take on one more responsibility. We sacrifice an evening of rest. We become accustomed to checking emails outside working hours or carrying tomorrow's worries into today.

Each adjustment feels manageable in isolation. Yet over time, the accumulation of these small adaptations can begin to reshape what we consider normal. This is where adaptation can become both a strength and a blind spot.

As conditions become familiar, they often require less conscious attention. What was once noticeable becomes ordinary. What was once questioned becomes expected. The extraordinary becomes routine.

Consider how often people describe feeling tired as though it were simply an unavoidable part of adulthood. Or how frequently we hear phrases such as "I'm just busy" or "that's life." For many people, stress is no longer experienced as something unusual. It has become the backdrop against which everyday life unfolds.

The difficulty is that once something becomes normal, we often stop questioning it.

We may not ask whether our pace of life is sustainable because everyone around us appears to be moving at the same speed. We may not recognise how much pressure we are carrying because those pressures have become woven into our daily routines.

The ability to cope can sometimes conceal the cost of coping

Psychologist Bruce McEwen's research on stress introduced the concept of allostatic load, describing the cumulative wear and tear that can occur when the body's stress response systems remain active for prolonged periods. Stress itself is not the problem. Human beings are designed to respond to challenges. Difficulties often arise when demands remain high, and opportunities for recovery become limited.

This raises an important question: If we are constantly adapting to pressure, are we equally attentive to recovery?

Many people can identify the things that create stress in their lives. They know what keeps them busy, what demands their attention, and what drains their energy. Recovery, however, is often less visible.

It tends to happen quietly through rest, meaningful relationships, movement, reflection, play, creativity, time outdoors, and moments where nothing needs to be achieved. When these experiences are regularly available, we may barely notice them. Yet when they become scarce, something can begin to feel out of balance.

Perhaps one of the most significant consequences of adaptation is not that we become better at tolerating difficult conditions, but that we become less aware of the conditions that help us thrive.

Human needs do not disappear simply because they are overlooked. The need for rest remains. The need for connection remains. The need for safety, belonging, meaning, movement, and recovery remains. What changes is our awareness of how those needs are being met, or whether they are being met at all.

This is where research into restoration becomes particularly interesting. Environmental psychologists Rachel and Stephen Kaplan explored how different environments affect our attention and mental fatigue. Their work suggested that natural environments may help restore our capacity for attention by engaging the mind in a gentler and less demanding way. 

Similarly, researcher Roger Ulrich found that access to natural views and environments may support recovery from stress. These findings do not suggest that nature is a cure for life's difficulties. Human well-being is shaped by many factors, including relationships, health, community, purpose, security, and access to support.

However, they do raise an important possibility. If certain environments help support restoration, what happens when opportunities to experience those environments become less common?

One of the challenges with restoration is that it often appears unproductive. Sitting beneath a tree, listening to birdsong, watching clouds move across the sky, walking without a destination, or spending time in conversation without an agenda can seem insignificant when measured against the demands of modern life.

Yet many of the conditions that support well-being do not produce immediate results. Their value often emerges gradually through repeated experiences of rest, reflection, connection, and recovery. Because these experiences are subtle, they can easily be crowded out by activities that feel more urgent.

Finding space to restore and reflect

This is one reason nature-based therapy can be valuable. Nature-based therapy does not assume that spending time outdoors will solve life's problems. Nor does it suggest that nature alone is responsible for healing. Rather, it recognises that the environment in which therapy takes place may influence the therapeutic process itself.

Walking, observing seasonal change, engaging with the senses, and spending time in natural environments can create opportunities to slow down and notice experiences that may otherwise remain hidden beneath the pace of everyday life.

For some people, this can provide space to reflect. For others, it may support feelings of connection, regulation, or perspective. The goal is not to escape life's challenges but to create conditions in which those challenges can be explored differently.

Perhaps the most important question is not how much stress we can tolerate. Perhaps it is this: What helps us feel restored, and have we stopped noticing its absence? Because if adaptation can change our perception of stress, it may also change our awareness of the things that help us recover.

In therapy, people often begin to notice aspects of themselves that have been hidden beneath years of coping and adaptation. They may rediscover needs for rest, connection, creativity, boundaries, self-compassion, or time for reflection that have been overshadowed by the demands of everyday life.

What initially presents as stress, anxiety, or burnout can sometimes become an exploration of what has been missing. Not because those needs disappeared, but because they gradually faded from awareness as other responsibilities took priority.

In this way, therapy can offer an opportunity to step outside of automatic patterns and become curious about what has become normal, what may have been overlooked, and what conditions best support well-being

Sometimes the first step towards well-being is not adding something new to our lives. Sometimes it is recognising what has quietly faded from view. And perhaps that is the invitation offered by Shifting Baseline Syndrome.

To become curious about what has become normal. To question what we have stopped noticing. And to consider whether some of the conditions that support our well-being have been there all along, waiting for our attention to return to them.
