Understanding Insomnia: Why Restful Sleep Eludes You
Insomnia isn’t just “one of those things”—it’s a signal from your body that something’s off. According to a 2019 study by the Sleep Foundation, up to 30% of adults experience short-term insomnia, with chronic cases affecting 10%. This study surveyed 10,000 participants across various demographics in the United States, making it a comprehensive snapshot of the issue. For our target audiences, insomnia is often tied to life stages: disrupted circadian rhythms for night owls and shift workers, hormonal shifts for menopausal women, anxiety spikes for professionals, academic students and erratic schedules for new parents.
Thankfully, most root causes are fixable without the fog-inducing pills. In the following sections, we’ll walk through 11 common culprits with tailored, practical solutions. Before we dive into the specific causes, know that our recommendations are based on comprehensive criteria. Rather than overwhelming you with options, we recommend one sleep solution backed by clinical evidence, user reviews, and sleep expert insights. Explore the Sleep Solution Backed by Research.
The Circadian Rhythm Connection
Understanding your internal clock—or circadian rhythm—is foundational. If this system is disrupted, it could be the first reason you’re struggling to sleep. Let’s start by examining how the circadian rhythm impacts your night. Check out my guide “How to Beat Insomnia in 12 Minutes: A Step-by-Step Guide to Getting Better Sleep”.
Cause 1: Circadian Rhythm Disruptions (For Shift Workers and Night Owls)
Night shift work or late nights disrupt your body clock and delay your 24 hour cycle.
Fix: Keep wake times consistent, use dim lights at night, and try chronotherapy—shift bedtime by 15 minutes a day to adjust, and when you get home in the AM go to sleep within 2 hours consistently. No alcohol or prescription drugs.
Pro Tip for New Parents: If baby’s sleep dictates yours, use a white noise machine like the Hatch Rest+ to help sync your naps and create a soothing environment.
Cause 2: Hormonal Fluctuations (Menopausal Women’s Nightmare)
Menopause triggers hormone dips, hot flashes, and night sweats that cause wake-ups. Fix: Use breathable bedding, keep your room cool, sip chamomile tea, and track cycles with an app. Sleep aids not recommended but if you have to, use a all natural remedy.
Fix: Layer breathable bedding and keep your room at 60-67°F. Herbal teas like chamomile can calm without grogginess. Track cycles with an app to predict rough nights.
A natural ally? Black cohosh supplements, but consult your doc. Note that while black cohosh is commonly used to reduce menopausal symptoms, it may cause mild side effects such as stomach upset, headaches, or rashes. It is not recommended for those with liver conditions.
Still awake at night? Discover the one fix most people miss that could help you fall asleep faster tonight, and all natural. Start Sleeping Better Tonight
Stress and anxiety keep you awake by elevating cortisol levels. Fix: Use 4-7-8 breathing, journal before bed, and avoid screens an hour before sleep.
Fix: Practice the 4-7-8 breathing technique: inhale for 4 seconds, hold for 7 seconds, and exhale for 8 seconds. Journal worries pre-bed to offload mental clutter. Avoid screens 1 hour before lights out—blue light blocks melatonin by up to 23%.
For calm without drowsiness, consider starting with the option that balances strength, safety, and consistency. I’d appreciate it if you could consult your provider for safety if you have other medications.
Cause 4: Poor Sleep Habits
Bad sleep habits confuse your brain and you yourself. Fix: Start a wind-down routine which I provide here, use your bed for sleep only, try blackout curtains, and eliminate caffeine and alcohol. Alcohol may cause you to pass out, but you’re really not deep sleeping; your liver is actually processing toxins, keeping you from deep REM sleep.
Fix: Create a wind-down ritual: 30 minutes of reading or stretching. Reserve a bed for sleep and intimacy only. Blackout curtains are a game-changer for light-sensitive sleepers. 👉 If the 3-3-3 rule helps you relax but doesn’t fully solve your sleep problem, there are other calming methods designed for deeper nighttime rest.
Cause 5: Caffeine, Stimulant, Alcohol Overload
Caffeine lingers, keeping you up. Fix: Stop caffeine after noon, try herbal teas, and track intake patterns. Stop drinking alcohol, more so excessively, because it stresses the liver and keeps you up.
Fix: Cut off caffeine post-noon and moderate alcohol. Research suggests that stopping caffeine intake by noon can reduce sleep-onset latency by approximately 14 minutes, providing a more restful night sooner. Switch to herbal alternatives, such as peppermint tea, and track intake with an app to spot patterns.
For a soothing, caffeine-free boost, try decaf green tea.
Cause 6: Screen Time Blue Light Exposure
Screens emit blue light that delays sleep. Fix: Use night mode or blue light blockers before bed; swap scrolling on your phone.
Fix: Enable night mode or wear blue-light blockers 2 hours before bedtime to ease your mind into relaxation, so your brain thinks dusk has arrived. This subtle cue can help you wind down naturally. Stop doom scrolling on your phone or computer, to further enhance the your bedtime routine for sleep.
For night owls, glare-free reading with a Kindle Paperwhite e-book can be a sleep-friendly alternative to bright screens. If you’re facing the same sleep issues night after night, the proper routine, paired with proven sleep support, like a bedtime routine, maybe a natural sleep aid, more exercise, and less caffeine after 12 noon and alcohol. Can make a real difference.
Cause 7: Irregular Eating Patterns
Heavy or missed meals disturb sleep. Fix: Eat dinner 3 hours, avoid exercise before bed and avoid alcohol.
Fix: Eat dinner 3 hours before bed; opt for light, sleep-promoting foods like cherries, cherry tart, (natural melatonin), or bananas (magnesium-rich). Avoid alcohol—it disrupts sleep despite initial drowsiness. Meals that are high in fat not recommended since they stress your liver, keeping you up.
Cause 8: Lack of Physical Activity
Sedentary days make sleep harder. Get 30 minutes of daily movement, but not 3 hours before bed. It’s an essential.
Fix: Aim for 30 minutes daily, but not within 3 hours of bed. Exercise for anyone will help sleep, exercise is a pillar good overall health.
Menopausal folks, gentle Pilates can ease aches and support overall health. Many adults struggle to meet the recommended levels of physical activity, so if you’re falling short, know you’re in good company. This shared challenge invites you to explore new, less daunting options, such as incorporating yoga into your routine. You don’t have to run a Boston marathon, walking is good exercise to help sleep.
Cause 9: Environmental Factors (Noise, Light, Temperature)
Noise, light, and heat disturb sleep. Fix: Try earplugs, a fan, cooling pillows, and, for parents, a bassinet.
Fix: Earplugs, white-noise fans, and cooling pillows combat this. For parents, co-sleeping aids like bassinets reduce disruptions. Night-shift workers should use earplugs to reduce external noise.
Cause 10: Underlying Medical Conditions
Conditions like sleep apnea or extreme insomnia can worsen over time.
Fix: Get medical advice to treat root causes before trying supplements. Here at Get More Sleep, we offer sleep guides and overall natural aids, and ways to calm your body to get better sleep.
You can consult a healthcare provider for screening and guidance before you try any supplements or self-treatment. Again, here at Get More Sleep, we provide clear guidance on improving sleep. Essential medical evaluation, such as a CPAP consultation for apnea or an iron check for RLS, can ensure that the right underlying issues are addressed. For natural support, magnesium glycinate can help reduce muscle twitches without causing morning fog.
Melatonin can be a helpful tool when used appropriately. It’s best to start with a low dose, around 0.5mg, taken 30-60 minutes before bed. For short-term situations, such as adjusting to a new time zone or a temporary shift in sleep schedule, melatonin may be helpful. However, it is generally not recommended for long-term daily use, as it might lead to dependency or reduced effectiveness. When lifestyle fixes aren’t enough, I personally recommend a gentle, non-habit-forming sleep aid that supports natural sleep cycles.
Cause 11: Medication Side Effects and OTC Sleep Aid Tolerance
Medications and frequent sleep aids disrupt sleep patterns. Fix: Review meds, taper sleep aids, and try CBT-I through apps.
Fix: Review meds with your pharmacist. Taper OTC aids gradually. Embrace CBT-I (cognitive behavioral therapy for insomnia) via apps like Sleepio.
For frustration-free alternatives, valerian root shines. If you’ve tried everything and still ask, “Why can’t I sleep at night?” — don’t give up.
