Are you waking up feeling just as tired as when you went to bed, struggling to remember simple things, or finding it nearly impossible to focus throughout the day? If so, you’re not alone and you’re in the right place.
Many people dealing with the beginning signs of cognitive decline and chronic fatigue are caught in a frustrating cycle of poor sleep, brain fog, and dwindling energy levels. But, the quality of your sleep could actually be a key player in turning things around.
Today, I’ll get into how optimizing your sleep is a large piece of the puzzle that can dramatically improve your cognitive health, boost your energy, and help you take back control of your life. From simple bedtime routines to creating the perfect sleep environment, I’m sharing my top tips from my experience as a functional medicine practitioner that can make a world of difference, starting tonight.
Let’s get started.
Why Sleep is Critical for Cognitive Health and Chronic Fatigue
Let’s start with why sleep is so crucial for your brain.
During sleep, your brain doesn’t just shut off—in fact, it’s incredibly active. One of the key functions of sleep is cognitive processing and memory consolidation. Think of it as your brain’s time to organize and file away everything you’ve learned throughout the day. Without adequate sleep, these processes are disrupted, leading to memory lapses and difficulties in concentrating.
Sleep also plays a crucial role in brain detoxification. During deep sleep, your brain’s glymphatic system works like a cleaning crew, clearing out toxins that accumulate during the day. When sleep is compromised, this cleansing process is incomplete, leaving you with old and broken parts to work with the next day and potentially leading to cognitive decline over time.
Now, let’s talk about chronic fatigue. If you’re already dealing with persistent tiredness, you know that sleep can be a double-edged sword. On one hand, restorative sleep is vital for recharging your energy levels. But on the other hand, poor sleep can exacerbate fatigue, trapping you in a vicious cycle where no amount of rest seems to make a difference.
Research has shown that individuals with Chronic Fatigue Syndrome often experience disrupted sleep patterns, leading to non-restorative sleep (Jackson et al). This means you might be sleeping, but not getting the deep, restorative sleep your body needs to truly recover. This only worsens fatigue and can also intensify cognitive symptoms, creating a downward spiral that’s hard to break.
Dr. Dale Bredesen, a leading expert in Alzheimer’s prevention and reversal, emphasizes the critical role of sleep in his ReCODE protocol for reversing cognitive decline. He highlights that consistent, quality sleep is essential for preventing the buildup of harmful proteins in the brain and maintaining overall brain health.
Moreover, studies published in journals like Nature (Csipo et al.) and Biochemistry Research
International (Bishir et al.) have demonstrated that poor sleep is directly linked to reduced cognitive performance and increased risk of neurodegenerative diseases. These findings are not just theoretical—they underscore the importance of making sleep a priority if you want to protect your cognitive health and manage chronic fatigue.
Common Sleep Disruptors in Cognitive Decline and Chronic Fatigue
So, now let’s talk about some common sleep disruptors.
1. Medications
Since my background is in pharmacy, let’s start with medications. Stimulants like Adderall, prescribed for focus in ADHD, can keep your brain too alert to wind down at night. And certain antidepressants, particularly those that increase serotonin, can also disrupt your sleep cycles, making it harder to get restorative rest.
Then, there’s another category to be mindful of: benzodiazepines, commonly used for anxiety or insomnia. While they may help you fall asleep faster, they can interfere with the deep stages of sleep that your brain needs for memory consolidation and recovery. So, even though you’re sleeping, you may not feel rested.
2. Stress and Anxiety
Next, let’s talk about stress and anxiety, particularly the internal dialogue that often accompanies cognitive decline. Thoughts like, ‘What if my memory gets worse?’ or ‘Will I ever feel normal again?’ can create a loop of worry that plays on repeat when you’re trying to fall asleep.
This kind of mental chatter, especially when paired with the fear of declining cognitive abilities, can significantly disrupt your ability to relax and drift off into a restful sleep.
3. Physical Symptoms
Physical symptoms such as joint pain, headaches, or hormonal imbalances—common in chronic fatigue—can also be major sleep disruptors. These symptoms not only make it difficult to fall asleep but can also cause you to wake up frequently during the night, preventing that deep, restorative sleep.
For instance, fluctuating hormone levels, particularly in women approaching menopause, can lead to night sweats and hot flashes that make staying asleep a challenge.
4. Lifestyle Factors
Then, irregular sleep routines, especially those where you go to bed at different times each night, can confuse your body’s internal clock. Consistent bedtimes are key to establishing a strong sleep-wake cycle.
Screen time before bed is another big one. The blue light emitted by phones, tablets, and TVs tricks your brain into thinking it’s still daytime, which inhibits the production of melatonin, the hormone responsible for sleep.
And, a lack of physical activity during the day can also make it harder for your body to feel ready for sleep at night. Even gentle exercise can help regulate your sleep patterns.
And, before we go any further, I want to go over a couple of myths about sleep.
Myths About Sleep
- Myth 1: ‘You can catch up on sleep over the weekend.’ In reality, while sleeping in on weekends might make you feel temporarily better, it doesn’t fully compensate for sleep lost during the week. Consistency is the key to truly restorative sleep.
- Myth 2: ‘Sleep aids are harmless.’ While some sleep aids can be helpful in the short term, many can lead to dependency or disrupt your natural sleep cycles over time, like I mentioned before. It’s important to use them cautiously and ideally under the guidance of a healthcare provider.
Practical Tips for Optimizing Sleep
Now, let’s dive into my top practical tips for optimizing your sleep.
1. Establish a Consistent Sleep Routine:
One of the most effective ways to improve your sleep is by establishing a consistent sleep routine. In fact, it’s so important that I made it my #1 recommendation. Going to bed and waking up at the same time every day, including weekends, helps regulate your body’s internal clock. This consistency trains your body to know when it’s time to wind down and when it’s time to wake up, leading to deeper and more restful sleep.
Remember, while it may be tempting to sleep in on weekends, sticking to your regular wake-up time will benefit you more in the long run.
2. Create a Sleep-Inducing Environment:
Your sleep environment plays a critical role in how well you sleep.
A cool, dark, and quiet bedroom can make a significant difference. Aim to keep your bedroom temperature between 60-68°F (15-19°C) for optimal sleep.
Consider removing electronic devices like TVs, smartphones, and tablets from your bedroom. The light from these devices can interfere with melatonin production, making it harder to fall asleep. Not to mention the electromagnetic fields (or EMFs) that these electronics emit, even when you’re not using them.
Blackout curtains are another great tool, especially if you’re sensitive to light or live in an area with a lot of street lights. I live in the middle of nowhere, Tennessee, so this isn’t as much of an issue for me as it may be for someone who lives in a city like Nashville. But blackout curtains can block out external light, helping to maintain a dark environment conducive to sleep.
And white noise can be a great addition to your nighttime routine. It helps drown unwanted noises and put your mind at ease having a constant steady noise in the background. We have one that we use every single night and absolutely love it. If you want to check out the one we use, it would be super helpful for me if you used my affiliate link, here.
3. Mindful Pre-Bedtime Routine:
What you do in the hour leading up to bedtime can set the stage for a restful night. Engaging in calming activities such as reading, listening to soothing music, or gentle stretching can signal to your body that it’s time to wind down.
Creating a ritual around these activities helps your body and mind transition from the busyness of the day to a more relaxed state, making it easier to drift off when your head hits the pillow.
4. Nutrition and Supplements:
What you eat and when you eat it can also impact your sleep.
Foods rich in magnesium, like leafy greens, nuts, and seeds, can promote relaxation and improve sleep quality. About 40% of the population seems to be deficient in magnesium, so many people may benefit from added magnesium before bed. If that’s something you want to try, here is my top recommendation and the one I take.

Chamomile tea is another great option due to its calming properties.
And, other supplements like melatonin can be beneficial, especially if you’re dealing with disrupted sleep patterns. However, it’s important to use them under the guidance of a healthcare professional to ensure they’re right for you.
And keep in mind that timing is key when it comes to meals. Aim to finish eating at least 2-3 hours before bed to give your body time to digest so your body can focus on the restorative things it needs to do while you sleep instead of digestion.
5. Manage Stress and Anxiety:
Stress and anxiety are major sleep disruptors, like I mentioned, but there are techniques you can use to manage them. Deep breathing exercises, meditation, or journaling before bed can help calm your mind and prepare you for sleep. For more tips on managing stress, read this blog post right here.
And remember, managing stress is a long-term process, so be patient with yourself as you find what works best for you.
Immediate vs. Long-Term Strategies
Now, it’s important to differentiate between tips that can have immediate effects and those that require time and consistency. For example, adjusting your room temperature and removing electronics can lead to immediate improvements in your sleep environment.
However, establishing a regular sleep routine, managing stress, and addressing underlying anxieties are long-term strategies that may take time to fully impact your sleep quality. Be consistent and give yourself grace as you work towards better sleep.
By establishing a consistent sleep routine and creating a restful environment, you can start getting better sleep that can enhance your memory, boost your energy levels, and lift your mood, helping you regain control over your life.
