What sleep deprivation is and why it destroys more than it seems

Sleep deprivation is not one sleepless night and not several difficult mornings in a row. It is a state in which sleep becomes chronically short and shallow, and the body gradually loses its ability to recover. A person may get used to this feeling, begin to perceive it as a “normal way of life,” but for the psyche and the body it is a constant emergency mode. As a clinical psychologist, I see sleep deprivation not as a household inconvenience, but as slow exhaustion of the nervous system. It begins imperceptibly: someone wakes up several times a night, someone cannot fall asleep for a long time, someone sleeps but does not feel rested. If this repeats day after day, a sleep deficit forms. It cannot be “caught up on during the weekend.” It accumulates like a debt.

Sleep deprivation very often affects parents. And not only mothers. Children affect adults’ sleep regardless of gender, age, or family structure. A baby who wakes frequently. A child with anxious sleep. A teenager who stays awake late at night and makes noise. And also constant internal tension: “I must wake up if something happens.” The parents’ brain stops fully switching off even during sleep. But it is important to understand: sleep deprivation is not limited to childcare alone. It is fueled by anxiety, responsibility, chronic stress, financial worries, strained relationships, and health problems. Sleep is the first thing to break down when the psyche constantly remains in a state of alertness. The main symptom of sleep deprivation is excessive daytime sleepiness, but it does not always look like a desire to sleep. More often it manifests as irritability, tearfulness, emotional numbness, forgetfulness, difficulty concentrating. A person begins to think more slowly, make worse decisions, and react more sharply to minor things. This is not a “bad character.” It is a tired brain operating without pauses. With prolonged sleep deprivation, both physical and mental resilience decrease. Risks grow gradually but systematically: depressive states, anxiety disorders, metabolic disturbances, excess weight, cardiovascular problems, hormonal imbalances. Sleep is not a bonus. It is a basic need, just like food and air.

It is worth speaking separately about the danger of fatigue in everyday life. With sleep deprivation, cognitive functions decrease by tens of percent. Reaction becomes slower, attention scattered. A person may not notice how exhausted they are and at the same time get behind the wheel, make important decisions, or be responsible for a child’s safety. Fatigue is often more dangerous than alcohol because it is insidious and not felt as a threat. Another trap of sleep deprivation is the habit of perceiving it as inevitability. Many parents think: “This is how it should be,” “Everyone lives like this,” “I’ll rest later.” But chronic lack of sleep does not go away on its own. It is either compensated by conscious effort or turns into chronic disorders. What is important to understand first of all: sleep deprivation is not guilt and not weakness. It is a consequence of the conditions in which a person lives. But it is also a signal that the body and psyche need support. Ignoring this signal means postponing a problem that becomes more difficult over time.

The recommendations here are not magical and not ideal. They are about reality. Sleep requires priority. Not perfect, but real. Sometimes this means postponing household chores. Sometimes it means asking for help. Sometimes it means sleeping during the day together with a child, even if “it’s not customary.” Daytime sleep does not replace nighttime sleep, but it can reduce the deficit. It is very important to remove stimulation before sleep. Screens, news, loud conversations, and tense thoughts do not allow the brain to switch into recovery mode. Sleep loves silence, darkness, and predictability. Sleep hygiene is not a luxury, but a survival tool. Physical activity, fresh air, regular meals, reducing caffeine, refusing alcohol as a “sleep aid” are simple but effective things. They do not cure sleep deprivation instantly, but return the body’s ability to fall asleep more deeply. And most importantly: if sleep does not recover even when all recommendations are followed, consultation with a doctor or sleep specialist is necessary. Sleep deprivation often masks other disorders: insomnia, breathing disorders during sleep, hormonal or mental problems. This is not something to endure.

Sleep is not weakness and not “free time.” It is the foundation on which a healthy psyche, children’s safety, and the ability to be alive rather than merely functional rest. And if it is lacking, it is always a sufficient reason to stop and take care of yourself.

I am Anna Boletska, a psychologist who has been working at the intersection of pain and strength for many years. My patients are military personnel, IDPs, and families who have lost loved ones. I listen when others are silent and help when it seems that there is no help anymore. I do not promise quick solutions. I stand for deep, honest work with oneself - through fear, fatigue, tears, and healing. My approach is empathy without judgment, conversation without templates, support without pathos. I love silence, simple things, strong coffee, and books that change my inner world. I write because words heal, just like a trusting look or a single “I hear you.” “Even in the darkest moments, there is a spark inside us. It is important not to extinguish it but to protect it.”
