Despite the common wisdom that sleep is important for overall health and wellness, in our over-scheduled, non-stop modern lives, we often trade precious sleep for other endeavors, like social media scrolling, mindless television, or completing your to-do list.
Without adequate sleep though, nearly every aspect of waking life becomes more effortful, labored, and emotionally less fulfilling (1). In today’s article, we’re going to review the effects of insufficient sleep and explore how sleep deprivation may be sabotaging your health.
Prioritizing and getting enough quality sleep is one of the most common concerns I see among clients. It literally affects everything from our mood, energy, blood sugar, eating habits, and mental clarity. Many of us struggle to make the changes to go to bed earlier, or create relaxing bedtime routine to help promote more restful sleep. If you have already made changes and are still not sleeping well, you will want to check out the sleep hygiene tips below to see if you’re missing something.
What is adequate sleep?
Proper rest is as important to our health as eating, drinking, and breathing (2). When we sleep, the brain and body slow down and engage in processes of recovery, promoting better physical and mental performance the next day and over the long term (3).
While each person will differ in the exact amount of sleep needed for replenishment, the National Sleep Foundation guidelines advise that healthy adults need between 7 and 9 hours of sleep per night. If you have a chronic health condition or experiencing an autoimmune flare, you may need more than the typical 7-9 hours.
So, if you’re consistently sleeping less than 7 hours per night, you wake feeling sleepy and physically drained, your mood is noticeably flattened, and your thinking feels sluggish and unfocused — you’re deprived of sufficient sleep (4).
How does sleep deprivation sabotage your health?
The symptoms of sleep deprivation are wide-reaching and they affect all aspects of your health.
Clinical symptoms include longer reaction times, distraction, disturbances in attention and concentration, forgetting known facts, difficulty in memorizing new information, and making mistakes and omissions (5).
Higher levels of stress are observed in sleep-deprived individuals, leading to increased tiredness, drowsiness, and irritability. Work effectiveness decreases and motivation usually falls. Reasoning slows down not only during the night of sleep deprivation but also on the following day (6).
Sleep deprivation may also play a role in the increased prevalence of diabetes and/or obesity. A 2007 sleep medicine study explored the relationship between sleep restriction, weight gain, and diabetes, showing that consistent lack of sleep leads to impaired glucose metabolism, increased appetite, and decreased energy expenditure (7).
Improving your sleep hygiene
As you can see, prioritizing sleep is incredibly important for your body to function optimally. If you’re experiencing any of the symptoms listed above, this is your sign to improve your sleep hygiene.
You can begin improving your sleep hygiene by focusing on consistent sleep and wake times (e.g. in bed every night by 10:30 pm and waking by 6:30 am). Ensure you’re sleeping in a cool, dark room and avoid blue light 1 hour before bed (i.e. no phone, tv, computer, or tablet). Listening to calming music, Yoga Nidra, utilizing the Calm app, or other meditation will further help you create a calming sleep sanctuary.
If you’ve implemented those changes (and I mean, truly made those changes), and you’re still not seeing improvements in your sleep, you may need to dig deeper to look for other root causes. Some issues that will cause sleep disturbances include environmental toxins like parasites, mold, or EMFs, hormonal imbalances, blood sugar dysregulation, or chronic infections. I would recommend working closely with your practitioner to find your root cause and ensure you address it properly to move forward in your health.
If you’re in a season of life right now where consistently obtaining an average of 8 hours of sleep is impossible, don’t fret. Know that there will come a time when you can appropriately prioritize your sleep. Until then, take a nap when it’s available, stay hydrated, eat well, get out in nature, and nourish your body in other ways that feel good. At the end of the day, we are looking for progress not perfection.
