Trauma Aware America

Sleep is one of the main ways the brain and body restore balance after the demands of the day. During sleep, the brain sorts and stores memories, processes emotional experiences, and clears away metabolic waste that builds up while we’re awake. It helps different parts of the brain communicate more effectively, which supports attention, learning, decision-making, and creativity.

From an Interpersonal Neurobiology perspective, sleep supports integration. It helps our nervous system coordinate information across the body, brain, and relationships. When sleep is disrupted, we become more vulnerable to threat responses, emotional reactivity, pain, inflammation, and difficulty connecting with others. When sleep is sufficient, we are more able to regulate our emotions, think clearly, recover from stress, and engage with the people around us in ways that promote health and well-being.

Sleep is not a luxury or a reward for getting everything done. It is a biological need that shapes how we feel, think, heal, and relate to one another every day.

The quality of our sleep emerges from the interaction of the body, brain, relationships, environment, stress load, physical health, and daily rhythms. Sleep disruption is often a sign that multiple systems are under strain rather than evidence of a personal failure or disorder.

Through an IPNB lens the question is, “What conditions is this person’s body living in that make sleep difficult?” before asking, “What technique can we use to force sleep?” That often leads to more useful solutions.

Key IPNB-informed points:

• Sleep supports integration across the brain and body. It helps organize memory, learning, emotional processing, immune function, pain regulation, and recovery.

• Chronic stress shifts the body toward vigilance. When vigilance remains elevated, falling asleep, staying asleep, and returning to sleep after waking can become more difficult.

• Human beings evolved as social creatures. A sense of safety, belonging, and predictability often supports sleep, while isolation, conflict, uncertainty, and social threat can interfere with it.

• Sleep problems are often effects rather than primary problems. Pain, grief, trauma, financial stress, caregiving burdens, medical conditions, medications, environmental disruption, and lack of social support can all contribute.

• The body tends to sleep best when daily rhythms are predictable. Regular exposure to daylight, movement, meals, and social contact helps anchor circadian timing.

• Sleep is strongly connected to homeostasis. When multiple physiological needs are unmet, sleep quality often suffers.

Things that often help:

• Get outdoor morning light within the first hour after waking, even if only for 10 to 20 minutes.

• Wake up at roughly the same time each day, including weekends when possible.

• Increase daytime movement, particularly walking outdoors.

• Avoid spending long periods indoors under artificial lighting without natural light exposure.

• Eat meals on a reasonably consistent schedule.

• Reduce stimulating activities during the hour before bed.

• Keep the sleep environment cool, dark, and quiet.

• Address pain, breathing issues, reflux, medication side effects, and other physical contributors.

• Build more moments of genuine social connection during the day. Positive social contact can influence physiological regulation in ways that support sleep later.

• If your mind becomes busy at night, externalize unfinished tasks by writing them down rather than trying to hold them mentally.

• If you cannot sleep after a prolonged period, get up and do something quiet and low-stimulation until sleepiness returns rather than spending hours frustrated in bed.

Things that are often overlooked:

• Loneliness can affect sleep.

• Ongoing conflict in important relationships can affect sleep.

• Financial insecurity can affect sleep.

• Chronic pain can affect sleep.

• Excessive caffeine, alcohol, and cannabis use can all affect sleep architecture, even when they seem to help initially.

• Sleep problems are frequently reduced when the broader conditions supporting regulation improve, even if no sleep-specific intervention is used.

When Nighttime is Associated With Danger

When sleep has been linked with traumatic experiences, the goal is not to trick or force the body into sleeping. The goal is to create conditions that help the body gradually learn that the present is different from the past.

• Many people with nighttime trauma histories find that early morning feels safer because daylight is approaching, other people are waking up, and the environment feels more predictable.

• Lack of daylight exposure, especially during winter, can make it harder for the circadian system to anchor itself. Morning light is one of the strongest signals that helps regulate sleep timing, mood, energy, and hormone rhythms.

• Trying to force an earlier bedtime often backfires because it increases performance pressure around sleep and reinforces the association between bed and frustration.

Instead of focusing on “going to bed earlier,” it can be more useful to focus on gradually increasing cues of safety and predictability throughout the day and evening.

Some possibilities include:

• Start with the wake time rather than the bedtime. Even shifting wake time earlier by 15 to 30 minutes every week can help move the sleep schedule gradually.

• Prioritize morning daylight exposure as soon as possible after waking, even if it’s later in the day than most people. If natural light is limited in winter, a clinically appropriate light box may help.

• Create experiences of connection and regulation before bed. A phone call with a trusted person, listening to a familiar voice, spending time with a pet, or engaging in calming social rituals can help counter isolation.

• Reduce the contrast between daytime and nighttime. Soft lighting, familiar sounds, weighted blankets if tolerated, or white noise can help create continuity rather than an abrupt transition into silence and darkness.

• Consider whether complete darkness feels supportive or activating. Some people with trauma histories sleep better with a small amount of light.

• Address environmental cues that increase vigilance. Locks checked once, pathways cleared, comfortable room temperature, reducing unexpected noises, and having needed items nearby can help.

• Finding ways to increase light exposure and movement during waking hours may help strengthen the body’s daily rhythms.

• If you cannot sleep, leaving the bed for a quiet, low-demand activity can prevent the bed itself from becoming associated with struggle.

Focusing on “What conditions help this person’s body feel safe enough to allow sleep to emerge?” can reduce shame and open the door to solutions that match the person’s lived experience rather than asking them to push harder against their own biology.
