A woman is sitting on a bed stretching her arms in front of a window.

Are you frequently fatigued in the morning, even after getting ample hours of sleep at night? While it can be a frustrating situation, there may be a simple explanation: you might be having poor sleep quality.


Poor sleep quality can lead to a variety of health problems, including weight gain, depression, and heart disease. Identifying the reasons for insufficient sleep is straightforward, but determining why our sleep isn’t restful is often trickier.

Nonetheless, it is still possible to do so. This article explores the importance of sleep quality, potential causes of poor sleep, and offers strategies to enhance your sleep quality.


Why is Sleep Quality Important?

During sleep, the body undergoes important physiological processes that are necessary for various functions such as cognitive functioning, immune function, and physical health.


Here are a few reasons why sleep quality is important:

1. Allow Our Bodies to Repair and Restore

When we sleep, our bodies release hormones that promote tissue growth and repair, as well as regulate our metabolism and immune system. This means that if we don't get good quality sleep, our bodies may not be able to repair themselves properly, leaving us vulnerable to a variety of physical health issues.

2. Keep Our Mental Health in Check

Studies have shown that poor sleep quality is associated with a higher risk of depression and anxiety. Individuals with poor sleep quality were more likely to experience negative emotions and less likely to experience positive emotions the following day [1].

With poor sleep quality, we may also feel irritable, moody, and find it difficult to concentrate, which can negatively impact our overall wellbeing and productivity.

3. Maintain a Healthy Weight

When we don't get enough quality sleep, our bodies produce more of the hormone ghrelin, which stimulates hunger, and less of the hormone leptin, which tells our bodies that we are full. This can lead to overeating and weight gain.

What Could be Causing Your Poor Sleep?

Several factors may contribute to poor sleep quality, including:

  • Stress: High levels of stress can make it difficult to fall asleep and stay asleep throughout the night.
  • Poor Sleep Habits: Irregular sleep schedules, excessive caffeine or alcohol consumption, and using electronic devices before bedtime can all interfere with sleep.
  • Environmental Factors: Noise, light, and temperature can all affect sleep quality.

Not everyone has the luxury of getting a good night's sleep. Sleep disorders like insomnia, sleep apnea, and restless leg syndrome can further impair sleep quality.

If you are having trouble sleeping, speak with your healthcare provider to identify any underlying conditions and determine the best course of treatment.


How to Improve Your Sleep Quality?

The good news is that enhancing the quality of our sleep might be as simple as improving our sleep hygiene. Similar to maintaining dental hygiene by regularly brushing and flossing, we can improve our sleep hygiene by adopting these few ideas:

1. Regular Sleep Schedule

One way is to establish a regular sleep schedule, which means going to bed and waking up at the same time each day.

Individuals who maintained a consistent sleep schedule had better cognitive performance and were less likely to experience mood disturbances compared to those with an irregular sleep schedule [2].

2. Sleep-friendly Environment

Creating a sleep-friendly environment entails keeping our bedroom cool, dark, and quiet. This can help minimise distractions and make it easier to fall asleep and stay asleep throughout the night.

3. Relaxing Bedtime Routine

Heard of the 3-2-1 technique for better sleep? It is an effective method that can help you to wind down and get ready for sleep. Here are the steps:

3 - Wind Down: Spend 3 minutes winding down before bedtime by engaging in a calming activity, such as reading a book, taking a warm bath, or practising relaxation techniques like deep breathing or gentle stretching.

2 - Unplug: Spend 2 minutes unplugging from electronic devices, such as phones, laptops, and tablets. The blue light emitted by these devices can interfere with the production of the sleep hormone melatonin, making it harder to fall asleep.

1 - Visualise: Spend 1 minute visualising yourself in a peaceful and comfortable sleeping environment. Imagine yourself feeling relaxed and comfortable, sinking deeper and deeper into a peaceful sleep.

Let’s not forget that when it comes to our overall health and wellbeing, good sleep quality is just as important as getting enough sleep.

By establishing healthy sleep habits, such as maintaining a regular sleep schedule, creating a relaxing bedtime routine, and a sleep-friendly environment, we can improve the quality of our sleep and reap the benefits of a good night's rest!

Rest, Recovery & the Art of Coming Back to Yourself — at the Half-Year Mark
By Esther Oon-Bybjerg June 17, 2026
Six months after her breakup, my client Janice (not her real name) told me she wasn't ready to date. At first, that didn't strike me as unusual. Breakups take time to recover from, and there is often wisdom and maturity in creating space to reflect before rushing into something new. But as we spoke, it became clear that Janice wasn't simply taking time to heal. She was waiting to become a different person. Since the breakup, she had immersed herself in self-development. She signed up for new sports, took on more responsibilities at work, read books on attachment theory, and spent countless hours trying to make sense of what the relationship had taught her. What began as a healthy desire to learn from the experience had gradually turned into a project with no clear endpoint. "I still have work to do," she explained. When I asked what would need to happen before she felt ready to date again, she described a version of herself who no longer became anxious if someone pulled away, no longer worried about rejection and no longer carried any emotional scars from past relationships. Listening to her, I found myself wondering whether she was talking about healing at all. What she seemed to be describing was the absence of vulnerability. After a painful breakup, it is easy to conclude that the safest path forward is to focus on ourselves. We tell ourselves that once we become more secure, more self-aware and less reactive, then we will be ready for a relationship. The underlying assumption is that love comes after healing. It is hardly surprising that so many people believe this. We are constantly encouraged to "work on ourselves first" by social media, self-help content and well-meaning friends. Yet the more I thought about Janice's dilemma, the more I questioned whether we have misunderstood how healing actually works. If relationships wound us, can they also heal us? If we gathered some of the most influential psychologists of the last century into one room and asked whether people need to become fully healed before entering a relationship, many of them would challenge the premise of the question itself. Not because healing is not important. Rather, because human beings do not heal in isolation as most imagine. John Bowlby, the founder of Attachment Theory, spent much of his career studying the relationships that shape our emotional lives. Together with Mary Ainsworth's research, his work highlighted how our sense of safety, trust and belonging develops through our interactions with others. This raises an interesting question. If some of our deepest insecurities were formed in relationships, can they be healed in isolation? Insight certainly helps. Understanding why we fear abandonment, struggle with trust or become anxious in intimacy can be valuable. Therapy can help us connect the dots between our past and present. Self-reflection can increase awareness of patterns that previously operated outside our consciousness. Yet there are some lessons that can only be learned through experience. A person who fears abandonment does not simply need insight into where that fear came from. At some point, they need experiences that challenge the fear itself. They need to discover what it feels like when somebody stays, follows through and remains emotionally present. This is what attachment researchers mean when they talk about "earned security." We do not think our way into security. We gradually experience our way into it. The parts of ourselves we only meet in relationships Janice nodded when we discussed this, but she still looked worried. "I understand that intellectually," she said, "but how can I be ready to date if I’m still feeling anxious?" It is a fair question. After all, if old insecurities continue to surface, doesn't that mean more healing is needed? Carl Jung might have offered a different perspective. He believed that relationships have a unique ability to reveal aspects of ourselves that remain hidden when we are alone. Much of what sits outside our awareness only becomes visible when it is activated. Anyone can feel calm and secure when there is nobody close enough to disappoint them. Intimacy has a way of exposing fears, assumptions and vulnerabilities that otherwise remain hidden. This can feel discouraging. Many people enter a new relationship only to discover that old insecurities reappear. They interpret this as evidence that they are not healed after all. The truth is the appearance of fear is not always a sign that healing has failed or one has regressed. Sometimes it is a sign that healing has reached a layer that was previously inaccessible. Healing as a Prerequisite As our conversation continued, Janice arrived at something deeper: "Part of me feels like I must fix myself first." I hear some version of this often in therapy. Not that people believe they are unlovable, but that they must become a much better version of themselves before they are ready for a relationship. Carl Rogers who devoted much of his career to understanding what helps people to grow and flourish, observed that growth thrives in an atmosphere of acceptance rather than constant evaluation. Yet Janice had turned healing into a qualification process. The more she learned about attachment, boundaries and emotional health, the more criteria she seemed to create for herself. The difficulty is that healing has no finish line. If complete healing is the standard for entering a relationship, many of us may spend years preparing for an exam that nobody ever passes. Relationships are one of the places where healing happens What strikes me is how many modern approaches arrive at similar conclusions despite speaking very different languages. Daniel Siegel's work in interpersonal neurobiology demonstrates how our brains and nervous systems continue to develop through relationships. Jeffrey Young of Schema Therapy suggests that deeply held beliefs such as "I am unlovable" are rarely transformed through insight alone; they often require corrective emotional experiences that challenge old assumptions. Even Acceptance and Commitment Therapy, which focuses heavily on psychological flexibility, would likely question the idea that we should wait until fear disappears before living our lives. One of its central messages is that meaningful action often comes before confidence, not after it. Different theories yet they point toward the same possibility: relationships are not simply the reward we receive after healing. They are one of the places where healing happens. Ready enough Near the end of our work together, Janice rewrote the rule she had been living by. Instead of telling herself, "I need to heal before I date," she began experimenting with a different idea: "I can keep healing while I date." On the surface, it sounds like a subtle shift in wording. Yet it reflects a fundamentally different understanding of how growth happens. The myth of being “ready” for love assumes that healing and relationships happen sequentially and that we fix ourselves first and connect later. Yet Bowlby, Rogers, Jung and many others show us that human beings are shaped in relationships, discover themselves in relationships and often heal in relationships too. That involves entering a relationship with enough self-awareness to recognise our patterns, enough responsibility to own them, and enough curiosity to remain open despite the uncertainty that comes with caring deeply about another person. As Donald Winnicott wrote, “It is a joy to be hidden, but disaster not to be found.” The goal is not to hide until all the work is done, but to keep growing while allowing ourselves to be seen.

In today’s performance-driven world, identity is often shaped by what we do, how we deliver, and how we are perceived. We become known for our roles, our output, our ability to keep going.But beneath this constructed identity lies a quieter question: Am I living and leading as a whole human being? This is where the conversation on identity begins to shift from definition to integration. The Hidden Cost of Fragmentation Many individuals move through their professional lives in subtle disconnection. The mind is engaged - analyzing, solving, producing. The body is overridden - pushing through fatigue and tension. Emotions are managed or suppressed. And a deeper sense of purpose is often left out entirely. Over time, this fragmentation accumulates. It begins to show up as fatigue, reduced clarity, emotional depletion, or a gradual sense of disengagement. In more visible forms, it is named as burnout. As this experience becomes widespread, it calls for a different understanding. Burnout is no longer best seen as an individual issue. It is a signal of accumulated strain, and often, of how work systems are designed around disconnection. This is what is opening new conversations in leadership today. A Reframing of the Conversation In a recent workshop. The Workplace Reset, with leaders and HR professionals, a different kind of dialogue began to emerge. Instead of asking, “How do we fix burnout?”, the question deepened: What are we asking of people and from which parts of themselves are they operating? There was a clear shift. Burnout began to be seen as organizational feedback, not personal failure. Wellbeing moved from a benefit to a foundation for performance. And resilience was reframed: not as silent endurance, but as the ability to stay connected while navigating challenges. At the heart of these reflections was a simple realization: People do not show up to work in parts. They show up as whole human beings. The Four Dimensions of Being To understand identity more fully, we must recognize the dimensions that shape our experience: • Mind — thoughts, logic, and sense-making • Body — physical state and lived experience • Emotion — inner and relational world • Spirit — values, purpose, and alignment When these operate in isolation, we may still function but often at a cost. Clarity becomes forced. Energy becomes depleted. Decisions feel misaligned. But when these dimensions integrate, something shifts. There is steadiness. Clarity becomes more natural. And a sense of coherence emerges in how we think, feel, and act. This is not about adding more. It is about reconnecting what has been separated. Identity as a Felt Experience Identity is often approached as something we define intellectually through titles or strengths. But true identity is not something we arrive at through thinking alone. It is something we experience . It is felt when actions align with values. When the body is not in resistance to the pace we keep. When emotions are acknowledged rather than suppressed. When work connects to meaning. The body plays a crucial role here. It holds signals the mind may override: tension, fatigue, ease. These are not inconveniences, but information. When we begin to listen, not just cognitively, but somatically, we access a more honest relationship with ourselves. From that place, identity becomes less about performance, and more about alignment. Embodied Leadership This shift toward integration is especially relevant in leadership. Traditional leadership has emphasized control, decisiveness, and cognitive strength. While important, these are no longer sufficient on their own. What is needed is embodied leadership . The capacity to lead from internal coherence. To stay grounded under pressure. To acknowledge emotions without being overwhelmed. To think clearly without disconnecting from intuition. To act in alignment with values, not just expectations. Leaders who operate this way shape environments. Where people feel safe enough to be honest. Where challenges can be named. Where wellbeing supports performance. In such spaces, people are not required to fragment themselves to succeed. They are able to show up more fully and contribute more meaningfully. Integration as Practice Integration is not a one-time insight. It is an ongoing practice. It requires pause withinmovement. Awareness within action. And the willingness to notice when we are out of alignmentand return. This may look like: • Checking in with the body, not just the mind • Noticing emotions without suppressing them • Creating small moments of stillness • Reflecting on whether decisions feel aligned These simple practices begin to shift how we relate to ourselves and our work. Harmony, Not Perfection Integration does not mean being perfectly balanced. Harmony is dynamic. There are moments when the mind leads, and moments when the body needs rest. Times when emotions surface, and times when purpose provides direction. The key is not control, but connection. To remain in relationship with all parts of ourselves and trust the intelligence within that allows us to respond with coherence. This is where resilience takes on a new meaning: Not endurance without struggle, but the ability to stay connected while moving through it. A New Way Forward As organizations navigate increasing complexity, there is an opportunity to redefine what it means to perform and to lead. Not through further optimization of parts but through integration of the whole. Because the most sustainable way of working is not built on pushing harder. It is built on coherence. On creating conditions—within individuals and systems—where people do not have to disconnect in order to function. Where identity is not something we perform, but something we live. And where, in returning to wholeness, we unlock not only wellbeing but a deeper, more grounded form of leadership.
