The conversation around wellness often focuses on nutrition and movement, yet growing research suggests that sleep influences overall mental health in many ways. Psychologist Dr. Amy Vigliotti, PhD, founder of SelfWorks, emphasizes that sleep is not merely a nightly routine; it is a biological requirement that shapes how people think, feel, and function. From her perspective, sleep deprivation has become so normalized among young adults that many no longer recognize the symptoms of chronic fatigue until it begins to affect their performance or emotional balance. Even when things go awry, adults might still not attribute the imbalance to their personal sleep debt.

Recent studies help illustrate what psychologist Dr. Amy and her team identify in their work. An analysis found that adults who routinely sleep fewer than seven hours show higher levels of cognitive lapses, including impaired attention and slower processing speed. Researchers note that even short-term sleep restriction can influence the accuracy of word recall, decision-making, and problem-solving, abilities that are essential for work, academic responsibilities, and everyday interactions. Psychologist Dr. Amy explains that this aligns with what many people experience when they say the wrong word, forget simple details, or struggle to stay organized after nights of insufficient rest.
According to psychologist Dr. Amy, the concept of sleep debt explains why a single long night of rest rarely resolves ongoing fatigue. She notes that many young adults assume that sleeping in on weekends compensates for sleep missed during the week, yet the body often keeps a cumulative “ledger.” This lingering deficit is part of what psychologist Dr. Amy explains as sleep debt, a form of fatigue taxation that influences energy, mental clarity, and motivation.
According to psychologist Dr. Amy, sometimes the signs of sleep debt appear in subtle but meaningful ways. She explains moments when clients feel overwhelmed by tasks that would otherwise be manageable. “Even individuals with healthy confidence may tell themselves, I can’t do this today, not because the task has changed, but because their cognitive load has,” she explains. “When sleep is limited, the brain must work harder to complete basic functions, organize thoughts, filter distractions, and maintain perspective.”
Psychologist Dr. Amy notes that memory and learning, two capacities young adults rely on heavily, are also shaped by sleep. She explains that during sleep, the brain engages in a process of learning consolidation, where new information is integrated and stored. Research found that slow-wave sleep plays a key role in stabilizing memory formation and improving the retention of newly acquired skills. “This suggests that students, early-career professionals, and individuals learning new skills may benefit from prioritizing rest rather than reducing hours to fit more tasks into the day,” she notes.
Psychologist Dr. Amy also highlights how quickly sleep-related fatigue can influence daily judgment and flow. She offers relatable examples: placing objects in the wrong spot, misreading simple cues, or feeling mentally overloaded by routine decisions. In her view, these moments are not personal shortcomings; they are signals. “When sleep is strained, even the simplest tasks can start to feel unmanageable,” she explains.
Monica Parham, LMHC, CBT-I specialist, of SelfWorks, points to another common pattern: the internal alarm system that activates when the body senses something is off. “Anxiety can function like our body’s smoke detector,” she says. “If a fundamental need such as sleep is not met, it’s natural for that alarm to ring.” According to a study, reduced sleep duration is associated with heightened emotional reactivity and increased symptoms of anxiety in adults.
This is part of why SelfWorks continues to support individuals in getting better sleep. In CBT-I, the treatment addresses common patterns that interfere with sleep and elevate anxiety, for example, scrolling to wind down or using the bed to get work done, and paradoxically worrying about how little sleep they are getting. Psychologist Dr. Amy notes that conversations around rest appear frequently in her sessions, especially among young adults who are navigating demanding schedules, academic pressures, and transitions into independence. She notes that SelfWorks offers ongoing workshops and individualized treatments to improve well-being, including the role sleep may play in daily functioning.
As research evolves, the message remains consistent across psychology and sleep science: adults may benefit from treating sleep as an essential pillar rather than an optional luxury. Psychologist Dr. Amy notes that this shift in perspective can be grounding for many people. “Once people understand the role sleep plays in their emotional and cognitive lives, they make decisions that honor their limits,” she explains. “And when we honor our limits, the rest of life begins to move with more ease, clarity, and purpose.”
