Sleep and Mental Health: Why Rest Isn’t a Luxury

You’ve pushed through another day on too little sleep. Coffee helps – until it doesn’t. Your thoughts feel foggy, your emotions raw. Small frustrations loom large. You know you should prioritize sleep, but there’s so much to do and only so many hours. Besides, you can function on less rest…can’t you?

At Televero Health, we work with many people who have come to see sleep as a luxury they can’t afford – something to squeeze in between work, family, and other responsibilities, often the first thing sacrificed when time runs short. They come to us for help with anxiety, depression, irritability, or concentration problems, often not connecting these struggles to their chronically disrupted sleep. What they discover is that adequate rest isn’t an indulgence but a biological necessity – one that affects virtually every aspect of mental and emotional wellbeing.

Maybe you recognize this pattern in your own life. Maybe you regularly shortchange your sleep to meet work deadlines, care for others, or simply have some quiet time to yourself after obligations are done. Maybe you’ve become so accustomed to functioning on insufficient rest that you’ve forgotten what being fully rested actually feels like. Maybe you pride yourself on needing less sleep than others, seeing it as a badge of productivity or strength. Maybe you try to get adequate rest but struggle with falling or staying asleep, particularly during periods of stress.

However it manifests, the undervaluing of sleep reflects powerful cultural messages that frame rest as unproductive or self-indulgent – something that can be sacrificed to more important priorities. We celebrate people who function on minimal sleep, treat rest as something to be “earned” rather than a basic need, and often fail to connect mental health struggles to sleep disruption, missing this foundational aspect of psychological wellbeing.

Yet research increasingly shows just how profoundly sleep affects the brain and mind. During sleep, your brain processes emotional experiences, consolidates learning, clears waste products, and restores neural function. Without adequate rest, these essential maintenance processes remain incomplete, affecting virtually every aspect of mental functioning.

The impacts are far-reaching. Emotional regulation suffers, making you more reactive to stressors and less able to recover from emotional triggers. Cognitive function decreases, affecting memory, focus, decision-making, and problem-solving. Stress hormones increase, keeping the body in a state of heightened alertness that further disrupts rest. Mood regulation mechanisms falter, potentially contributing to both anxiety and depression. Even your perception of social cues can shift, making you more likely to misinterpret others’ expressions and intentions.

We see these effects in countless ways. The person whose anxiety increases dramatically during periods of poor sleep, creating a cycle where worry disrupts rest and sleep deprivation heightens anxiety. The individual whose irritability and conflict with loved ones spikes when rest is insufficient, damaging important relationships. The client whose persistent low mood improves significantly when sleep issues are addressed, revealing how closely depression and disrupted rest can be connected. The professional whose work performance and job satisfaction suffer during periods of sleep deprivation, despite putting in longer hours.

If sleep has fallen to the bottom of your priority list, or if you struggle to get the rest you need despite your best efforts, know that addressing this fundamental need isn’t self-indulgent or weak. It’s one of the most important foundations of mental health – not a luxury to enjoy when everything else is done, but a necessity that makes everything else function better.

In therapy, we help people rebuild a healthier relationship with sleep through several approaches. First, by exploring the practical, emotional, and belief-based factors that might be interfering with adequate rest. Then, by developing personalized strategies to address these specific factors rather than applying one-size-fits-all sleep advice. Finally, by working with any underlying mental health issues that may be contributing to sleep difficulties, recognizing the bidirectional relationship between rest and psychological wellbeing.

These strategies might include practical adjustments to sleep timing, environment, or routines to create more favorable conditions for rest. Or techniques to calm an overactive mind that prevents sleep onset or causes middle-of-the-night waking. Or approaches to address anxiety about sleep itself, which can create a frustrating cycle where worry about not sleeping makes rest even more elusive. Or exploration of beliefs about sleep, productivity, and self-worth that may be contributing to the deprioritization of this essential need.

What many discover through this process is that adequate sleep doesn’t just relieve fatigue – it transforms their entire experience of life. Problems that seemed overwhelming become more manageable. Emotions that were difficult to regulate become less volatile. Relationships improve as irritability decreases and patience expands. Cognitive tasks that required immense effort become more accessible. The world simply looks and feels different when viewed through the lens of a well-rested mind.

They also discover that prioritizing sleep doesn’t necessarily mean accomplishing less. While it may require adjusting schedules or expectations, the improved efficiency, focus, and cognitive function that come with adequate rest often allow for greater productivity in less time. The extra hours gained by cutting sleep frequently yield diminishing returns, as the quality of work, decision-making, and problem-solving all decline in a sleep-deprived state.

Of course, there are seasons of life when optimal sleep is genuinely difficult to achieve – when caring for young children, during acute crises, or in certain work situations. The goal isn’t perfection but progress – moving toward a more sustainable relationship with rest while finding ways to support mental health during periods when ideal sleep isn’t possible.

Because the truth is, while our culture may frame sleep as expendable, your brain and body maintain a different perspective. They require adequate rest for optimal functioning, with consequences for mental health when this need goes unmet. And while changing sleep patterns can be challenging – particularly if insufficient rest has become normalized in your life – few interventions offer more comprehensive benefits for psychological wellbeing than rebuilding a healthy relationship with this fundamental biological necessity.
