Key Takeaways:
- Types of Insomnia: Insomnia is categorized into three main types: sleep-onset (difficulty falling asleep), sleep-maintenance (waking up in the middle of the night and struggling to fall back asleep), and mixed insomnia (a combination of both). Sleep-maintenance and mixed insomnia are particularly common.
- Prevalence and Impact: Insomnia affects 10–30% of adults chronically, with even more experiencing occasional disruptions. Symptoms include trouble sleeping, daytime fatigue, irritability, and difficulty concentrating, significantly impacting overall well-being.
- Stress and Cortisol: Chronic stress and elevated nighttime cortisol levels often contribute to middle-of-the-night awakenings, signaling the importance of stress management in improving sleep quality.
- Sleep Strategies: If awake for more than 20 minutes, leave the bed and engage in relaxing, low-stimulus activities (e.g., reading or listening to soothing music). Avoid activities like checking emails or using screens, which can reinforce wakefulness.
- In-Bed Relaxation Techniques: On nights when getting out of bed feels too difficult, try deep breathing, progressive muscle relaxation, or visualizing calming scenes to ease your mind and body back into sleep.
- Reinforcing Healthy Associations: Over time, consistent application of these strategies helps retrain the brain to associate the bed with sleep rather than wakefulness, improving sleep habits and reducing insomnia.
In the silence of the night, when darkness envelops the sky, many find themselves caught in a battle against sleeplessness, where the mind races and rest remains elusive. This phenomenon, commonly known as insomnia, especially the kind that strikes in the middle of the night, is not just a nuisance; it’s a significant disruptor of well-being, health and longevity.
Understanding Middle of the Night Insomnia
I work nights in a suburban emergency room. About once a week, I encounter a patient who visits the ER because they can’t sleep and asks for medication to help them fall asleep. Instead of immediately prescribing something like Valium, I prefer to sit with them to discuss their sleep habits and routines. After our conversation, they may still leave with a prescription. Still, they also leave equipped with various strategies for managing insomnia, ensuring they don’t have to visit the ER as a last resort.
As an ER professional witnessing the weary-eyed and desperate for relief, I’ve seen firsthand the struggle and the profound impact on the “insomnia brain,” a term reflecting the neurological turmoil caused by chronic sleep disturbances.
Insomnia comes in many forms, but one that particularly vexes many is sleep maintenance insomnia. This is when you find yourself waking up in the dead of night, the meaning of a “sleepless night” taking on a stark reality. It’s a frustrating interruption of rest that leaves you feeling helpless as the clock ticks away the minutes and hours until dawn.
The reasons behind this nocturnal awakening can be as varied as the individuals it affects, but understanding the root causes is the first step towards taming the beast.
Types of Insomnia
There are three types of insomnia:
- Sleep-Onset Insomnia: You go to bed but can’t fall asleep.
- Sleep Maintenance Insomnia: You fall asleep but wake up in the middle of the night and can’t fall back asleep.
- Mixed Insomnia: You struggle to fall asleep, and when you do, you wake up in the middle of the night and can’t return to sleep.
I will focus primarily on sleep maintenance and mixed insomnia, as these are the most common types I see in the ER.
How common is insomnia?
Insomnia is surprisingly common, affecting a large swath of the global population. Roughly 10% to 30% of adults deal with chronic insomnia, and this number jumps even higher when you consider those who experience it occasionally—up to half of us will face some sleep disruption at one point or another. Older adults and women tend to struggle with it more frequently.
Factors like stress, lifestyle shifts, underlying health issues, and even our environment play significant roles in disturbing our sleep. Understanding just how widespread insomnia is can really highlight the need to prioritize sleep as a vital part of maintaining our overall health.
What are the symptoms of insomnia?
Insomnia isn’t just about having trouble falling asleep; it brings a whole host of symptoms that can affect nearly every part of your day. If you’re experiencing chronic insomnia, you might find yourself lying awake at night, tossing and turning, or waking up several times throughout the night. But the impact doesn’t stop when the sun comes up.
During the day, insomnia can leave you feeling exhausted, make it hard to concentrate, and can even lead to irritability or anxiety. It’s a cycle that disrupts not only your nights but your days as well, making it challenging to function at your best.
Understanding Cortisol's Role in Sleep
Recent “sleep study insomnia” research has highlighted a fascinating link between cortisol levels and sleep patterns. For those who find the night restlessly staring back at them, it’s often due to a spike in cortisol, the stress hormone, that should naturally be lower during the night. This spike can trigger the brain to transition from sleep to a state of alertness, thus causing restless sleep.
For those with insomnia, these levels may spike unexpectedly at bedtime and during the night due to chronic stress. I often tell my patients that middle-of-the-night insomnia is the body’s revenge for unresolved stress.
Strategies for Managing Insomnia
What to Do When You Wake Up at Night
If you wake up in the middle of the night and can’t fall back asleep, avoid staying in bed awake for extended periods. Getting up and out of bed helps prevent your brain from associating your bed with wakefulness.
Our brains are adept at forming associations. For instance, you might not feel hungry until you see it’s lunchtime on your watch. Similarly, if you spend long periods awake in bed, your brain will start to associate your bed with being awake.
Activities to Consider
If you find yourself awake after about 20-25 minutes of tossing and turning:
- Give yourself some compassion and reassure yourself that it’s okay to be awake.
- Move to a different room if possible, and engage in a relaxing activity under dim lighting, such as reading a book or listening to a podcast or soothing music.
What to Avoid
- Do not check emails or work on pending tasks.
- Avoid browsing social media or eating, as these activities can train your brain to wake you up for these reasons.
Returning to Bed
Only go back to bed when you feel sleepy. There is no set time limit for how long you should stay up; it could be as short as 15-20 minutes or several hours. The key is to ensure you are sleepy before returning to bed to avoid lying awake.
Gradually, as you practice these strategies, you will relearn the association that your bed is a place for sleep. This is also why it’s important for parents to return their children to their own beds after a nighttime awakening—to reinforce the bed’s association with sleep.
Many of my patients have found these strategies effective, and they often return to tell me how much better they are sleeping. This is just part one of a five-part series on what to do when you can’t fall asleep.
What Can You Do If It's Too Hard to Get Out of Bed?
There will be night when it’s just to hard to get out of bed and go to a different room. What can you do if this happens? There are several things you can do to help yourself fall back asleep. First and foremost, take a deep breath and try to relax. It’s natural to feel a bit anxious or annoyed when you wake up unexpectedly, but letting go of those feelings will make it easier to drift back into dreamland. Focus on your breath, inhaling deeply through your nose and exhaling slowly through your mouth. This simple act of a mindful deep breath mindfulness can help calm your mind and body, making it easier to fall back asleep.
Another helpful technique is to engage in some gentle stretching while lying in bed. Start by stretching your arms overhead, feeling the tension release from your muscles. Then, stretch out your legs and wiggle your toes. These simple movements can alleviate any physical discomfort and promote relaxation. Additionally, you can try progressive muscle relaxation, where you tense and then release each muscle group in your body, starting from your toes and working your way up to your head. This technique not only helps you relax but also redirects your focus away from any racing thoughts.
If you find that your mind is still racing and preventing you from falling back asleep, try visualizing a peaceful scene or engaging in guided imagery. Imagine yourself lying on a beautiful beach with the sound of waves crashing gently in the background. Picture yourself sinking deeper into the sand with each breath, letting go of any tension or stress. Guided imagery can transport your mind to a serene place, allowing you to let go of any worries and fall back asleep peacefully.
Remember, it’s important to be patient with yourself when trying to fall back asleep. Avoid looking at the clock or worrying about how much time you have left before morning. Instead, focus on the present moment and trust that sleep will come naturally. With these techniques and a positive mindset, you’ll soon find yourself drifting off into a deep and restful slumber once again.
How ER Insights Can Transform Your Sleep
I remember one patient who, after implementing these strategies, returned to express their gratitude. They’d broken the cycle of sleepless nights and found a new peace in the darkness that had once been so daunting. Their story is a testament to the potential for change, for reclaiming the night, and for finding rest once more.
