The Connection Between Sleep, Routine, and Nervous System Regulation

I am a licensed therapist who helps clients heal from insomnia using cognitive behavioral therapy for insomnia (CBT-I), the first-line treatment for chronic insomnia. One simple recommendation I often make is to use consistent background noise, such as a fan, white noise, static, or steady rainfall.

The specific sound matters less than its consistency. Steady background noise can soften louder or more distinct sounds that might otherwise wake you. This is why I generally don’t recommend leaving the television on or playing an audiobook throughout the night without a timer. These can feel comforting, especially for people with a history of trauma, but changing voices, music, and volume can interrupt sleep.

The same is true of nature recordings that include unpredictable sounds, such as birds suddenly trilling. If you enjoy nature sounds, steady rain or another continuous sound may be a better choice.

Of course, sleep is personal. A bedroom temperature between 65 and 68 degrees is often recommended, but some people sleep best at 64 degrees, while others prefer 70 degrees with warm blankets. The goal is not to follow every recommendation perfectly. It is to discover what helps your body feel comfortable and safe enough to rest.

Regulation Begins With Your Daily Routine

As a licensed marriage and family therapist, I help people regulate their nervous systems, whether they are struggling with sleep, stress, or neurodivergence. One of the biggest obstacles I see is an irregular sleep schedule combined with an inconsistent daily routine.

Our nervous systems are also affected when we skip meals, work without breaks, and remain in a constant state of go, go, go.

Our culture celebrates productivity, while rest and basic self-care are often treated like luxuries. Sleep becomes something we can catch up on later. Breaks become something we must earn. But rest is not a reward for finishing everything. It is part of what allows our bodies and minds to function well in the first place.

Put Rest on the Calendar

I recommend literally blocking out your bedtime, your sleep hours, and an hour to wind down without screens. It can also help to plan a gentle start to the morning, take a 30-minute to one-hour lunch break, schedule regular meals and snacks, and build two or three media-free breaks into the day.

Ideally, one of those breaks might include a brisk 20-minute walk or another form of physical activity. Movement can reduce stress, restore energy, and support nervous system regulation without requiring another cup of caffeine.

Many people will read these recommendations and immediately think, “But my schedule doesn’t allow that.”

That reaction is important information.

If your schedule does not allow eight to nine hours of sleep, time to wind down, regular meals, or a few breaks during the day, your life may not be structured in a way that sustainably supports a regulated nervous system. Parenting, work, caregiving, and financial realities can make change difficult, but our bodies still have basic biological needs.

This is not about creating a perfect routine. It is about noticing when the structure of your life repeatedly asks your nervous system to function without enough rest, nourishment, or recovery.

If your life consistently does not allow you to meet those needs, it may be worth asking a bigger question: What has to change?
