Melatonin Heart Health Study 2025: What Charlotte Residents & People in Recovery Need to Know About Sleep Safety
A groundbreaking study presented at the American Heart Association’s Scientific Sessions 2025 has revealed concerning findings about melatonin supplements—one of America’s most popular sleep aids. Researchers analyzing health records from over 130,000 adults found that long-term melatonin use (one year or more) was associated with a 90% higher risk of heart failure, more than triple the hospitalization rate, and twice the death rate compared to non-users. For Charlotte, NC residents—particularly those in addiction treatment or recovery who commonly struggle with sleep disturbances—these findings raise critical questions about sleep medication safety.
At Nova Transformations in Charlotte, we recognize that sleep problems are nearly universal among people with substance use disorders, affecting up to 75% of individuals in recovery. Poor sleep is a major relapse trigger, yet the quest for better sleep can lead people toward potentially harmful solutions—whether unregulated supplements like melatonin or prescription sleep medications with addiction potential. Understanding the latest research on sleep aid safety is essential for making informed choices that support both recovery and overall health.
This comprehensive guide explores the 2025 melatonin heart health study, why sleep problems are so common in addiction and recovery, the complex relationship between sleep medications and substance use, safe alternatives to melatonin, and evidence-based sleep strategies integrated into addiction treatment at Nova Transformations in Charlotte.
Higher risk of heart failure in people using melatonin for 1+ years (American Heart Association 2025 Study)
The 2025 Melatonin Heart Health Study: Key Findings
Study Overview
Researchers from SUNY Downstate Health Sciences University analyzed five years of electronic health records from the TriNetX Global Research Network, examining 130,828 adults with chronic insomnia.
Study Design:
- Participants: 130,828 adults (average age 56) with chronic insomnia
- Comparison groups: Long-term melatonin users (1+ year) vs. non-users
- Follow-up period: 5 years
- Data source: International database of de-identified medical records
- Exclusions: People with pre-existing heart failure or using other sleep medications
Shocking Results
| Outcome | Melatonin Users | Non-Users | Increased Risk |
|---|---|---|---|
| Heart Failure Diagnosis | 4.6% | 2.7% | 90% higher |
| Heart Failure Hospitalization | 19% | 6.6% | 3.5x more likely |
| Death from Any Cause | 7.8% | 4.3% | 2x more likely |
Important Context
The researchers emphasize several critical points:
- Correlation, not causation: Study shows association, not proof that melatonin directly causes heart failure
- Marker, not cause: Long-term melatonin use may be a signal of underlying health problems rather than the cause
- Not peer-reviewed yet: Findings are preliminary; full study awaits publication
- Prescription records only: Study tracked prescribed melatonin, missing OTC users
- No dosage data: Researchers didn’t know how much melatonin people took
⚠️ What This Study Means for You
If you’re currently taking melatonin:
- DO NOT stop taking it immediately without consulting your doctor
- Schedule an appointment to discuss your sleep issues
- Get evaluated for underlying conditions causing insomnia
- Explore behavioral sleep strategies
- Consider cardiovascular screening if using melatonin long-term
Melatonin is NOT approved for chronic insomnia treatment—it’s intended for short-term use only.
Why the Connection?
Researchers propose several possible explanations:
1. Insomnia as a Heart Failure Risk Factor:
- Chronic insomnia increases blood pressure
- Raises stress hormones (cortisol)
- Increases inflammation
- Disrupts circadian rhythms affecting heart function
- People needing long-term melatonin may have severe insomnia, which itself increases heart risk
2. Underlying Conditions:
- Depression and anxiety (both linked to heart disease) cause insomnia
- Undiagnosed sleep apnea (major heart failure risk)
- Other medical conditions causing both sleep problems and heart issues
3. Possible Direct Effects (needs more research):
- Melatonin affects cardiovascular system
- Long-term supplementation may disrupt natural melatonin production
- Interaction with medications
- Unregulated supplements—quality varies wildly
Of people in addiction recovery experience sleep disturbances—much higher than general population
Sleep Problems in Addiction and Recovery
Sleep disturbances and substance use disorders are deeply intertwined, creating a vicious cycle that complicates recovery.
Why Sleep Problems Are Universal in Addiction
During Active Addiction:
- Stimulants (cocaine, meth): Prevent sleep; crash leads to excessive sleeping
- Opioids: Disrupt sleep architecture, reduce REM and deep sleep
- Alcohol: Sedates but destroys sleep quality; frequent awakening
- Cannabis: May help falling asleep but reduces REM sleep
- Benzodiazepines: Tolerance develops; dependence creates rebound insomnia
During Withdrawal:
- Severe insomnia is hallmark symptom of withdrawal from most substances
- Alcohol withdrawal: Profound sleep disruption, nightmares, night sweats
- Opioid withdrawal: Severe insomnia, restless legs, body aches preventing sleep
- Stimulant withdrawal: Hypersomnia (excessive sleeping) followed by insomnia
- Benzodiazepine withdrawal: Severe, potentially dangerous insomnia
In Early Recovery:
- Sleep architecture remains disrupted for weeks to months
- Post-acute withdrawal syndrome (PAWS) includes persistent insomnia
- Anxiety and depression (common in early recovery) worsen sleep
- Nightmares and vivid dreams are common
- Difficulty falling asleep and staying asleep
Sleep as a Relapse Trigger
Poor sleep is one of the most powerful relapse triggers:
- Exhaustion reduces willpower and decision-making ability
- Sleep deprivation increases cravings
- Desperation for sleep may lead to substance use
- Emotional dysregulation from poor sleep increases relapse risk
- Cognitive impairment interferes with recovery skills
🚨 The Sleep-Substance Use Vicious Cycle
1. Substance use disrupts sleep
↓
2. Poor sleep increases cravings and reduces coping ability
↓
3. Person uses substances to “help sleep” or manage exhaustion
↓
4. Substance use further disrupts sleep
↓
CYCLE REPEATS
Breaking this cycle requires addressing sleep problems in recovery WITHOUT turning to addictive substances or potentially harmful supplements.
The Melatonin Dilemma in Recovery
For people in recovery desperate for sleep, melatonin often seems like the perfect solution—it’s “natural,” available over-the-counter, non-addictive, and widely perceived as safe. But the 2025 study raises important concerns.
Why People in Recovery Turn to Melatonin
- Avoiding prescription sleep medications with addiction potential (Ambien, benzodiazepines)
- Seeking “natural” solution
- No prescription required
- Recommended by well-meaning friends/family
- Desperation for sleep relief
Problems with Melatonin in Recovery
1. Ineffective for Chronic Insomnia:
- Melatonin NOT FDA-approved for insomnia treatment
- Intended for circadian rhythm disorders (jet lag, shift work)
- Modest effects on sleep onset (falling asleep faster)
- Little effect on sleep maintenance (staying asleep)
- Tolerance may develop with long-term use
2. Unregulated Supplement:
- No FDA oversight of supplements
- Actual melatonin content varies wildly (400% variation found in testing)
- May contain contaminants
- Dosage inconsistency
- Some products contaminated with serotonin (dangerous)
3. Potential Heart Risks:
- 2025 study findings raise safety concerns
- Long-term effects not well-studied
- Many people in recovery have cardiovascular risk factors
4. Doesn’t Address Root Causes:
- Doesn’t fix disrupted sleep architecture from substance use
- Doesn’t treat underlying anxiety, depression, trauma
- Doesn’t address poor sleep hygiene
- Bandaid solution rather than healing
Safe Alternatives to Melatonin for Sleep in Recovery
Effective sleep restoration in recovery requires comprehensive approaches that address underlying causes rather than simply masking symptoms.
Evidence-Based Sleep Strategies
1. Cognitive Behavioral Therapy for Insomnia (CBT-I):
The gold standard non-medication treatment for chronic insomnia:
- Addresses thoughts and behaviors perpetuating insomnia
- Sleep restriction therapy (counterintuitively effective)
- Stimulus control (re-associating bed with sleep)
- Cognitive restructuring (changing anxiety about sleep)
- More effective than medication for long-term improvement
- No side effects or risks
2. Sleep Hygiene Practices:
- Consistent sleep schedule: Same bedtime/wake time every day (even weekends)
- Dark, cool bedroom: 60-67°F optimal temperature
- No screens 1-2 hours before bed: Blue light disrupts melatonin
- No caffeine after 2pm
- Regular exercise: But not within 3 hours of bedtime
- Relaxing bedtime routine: Reading, gentle stretching, warm bath
- Reserve bed for sleep and sex only—not TV, work, phone
3. Mindfulness and Relaxation Techniques:
- Progressive muscle relaxation: Systematically tensing and relaxing muscle groups
- Guided imagery
- 4-7-8 breathing: Inhale 4 counts, hold 7, exhale 8
- Body scan meditation
- Yoga nidra (yogic sleep)
4. Treating Underlying Conditions:
- Depression and anxiety treatment: Therapy and/or non-addictive medications
- Trauma processing: EMDR, trauma-focused therapy
- Chronic pain management: Non-opioid approaches
- Sleep apnea screening and CPAP treatment if indicated
Medications for Sleep in Recovery (When Necessary)
Sometimes medication is needed, but careful selection is critical:
Non-Addictive Options:
- Trazodone: Antidepressant commonly used for sleep, low addiction risk
- Mirtazapine: Antidepressant with sedating effects
- Doxepin (low dose): Antihistamine effect for sleep
- Hydroxyzine: Antihistamine for anxiety and sleep
Medications to AVOID in Recovery:
- Benzodiazepines (Xanax, Valium, Ativan, Klonopin): Highly addictive, dangerous in recovery
- Ambien, Lunesta: Addiction potential, dangerous side effects
- Barbiturates: Highly addictive, deadly
💡 The Best Sleep “Medication” is Time
Sleep naturally improves with sustained sobriety:
- Sleep architecture begins normalizing after 1-2 months sober
- Continues improving for 6-12+ months
- Brain healing restores natural sleep-wake cycles
- Anxiety and depression improve, reducing sleep disruption
Patience and sleep hygiene practices allow natural healing rather than dependence on external sleep aids.

Frequently Asked Questions
Do NOT stop taking melatonin abruptly without consulting your doctor, but DO schedule an appointment to discuss the findings. The 2025 American Heart Association study found that adults with chronic insomnia who used melatonin for one year or more had 90% higher risk of heart failure, 3.5x higher hospitalization rate, and 2x higher death rate compared to non-users. However, important context includes that this study shows correlation not causation—it doesn’t prove melatonin directly causes heart problems, the association may indicate that long-term melatonin use is a marker of severe underlying insomnia which itself increases heart risk, the study hasn’t been peer-reviewed yet and is considered preliminary, and researchers note more investigation is needed. If you’re currently taking melatonin, schedule a medical evaluation to identify root causes of your insomnia, get cardiovascular screening if you’ve used melatonin long-term, explore evidence-based alternatives like Cognitive Behavioral Therapy for Insomnia (CBT-I), improve sleep hygiene practices, and address underlying conditions like anxiety, depression, or sleep apnea. For people in recovery from addiction, working with addiction specialists who understand safe sleep treatment is essential. At Nova Transformations in Charlotte, we help clients achieve restful sleep through evidence-based approaches that don’t involve risky supplements or addictive medications. Call (704) 961-9322 for guidance on safe sleep strategies.
Sleep problems affect up to 75% of people in addiction recovery, much higher than the general population, due to multiple factors. During active addiction, substances profoundly disrupt sleep architecture with stimulants like cocaine and meth preventing sleep entirely followed by crash periods, opioids disrupting REM and deep sleep cycles, alcohol causing fragmented sleep despite sedation, and benzodiazepines creating tolerance and dependence leading to rebound insomnia. During withdrawal, severe insomnia is a hallmark symptom across almost all substance classes including alcohol withdrawal causing profound sleep disruption with nightmares and night sweats, opioid withdrawal producing severe insomnia with restless legs and body aches, stimulant withdrawal causing hypersomnia followed by insomnia, and benzodiazepine withdrawal creating potentially dangerous severe insomnia. In early recovery, sleep architecture remains disrupted for weeks to months even after detox, post-acute withdrawal syndrome (PAWS) includes persistent sleep disturbances, co-occurring anxiety and depression worsen sleep, nightmares and vivid dreams are common, and the brain needs time to heal and restore natural sleep-wake cycles. Additionally, many people used substances specifically to help them sleep, so removing that crutch leaves the original insomnia plus substance-induced sleep disruption. Good news: sleep naturally improves with sustained sobriety as the brain heals over 6-12+ months. At Nova Transformations, we provide comprehensive sleep treatment integrated into addiction care helping clients restore healthy sleep without turning to risky supplements or addictive sleep medications. Sleep improvement is possible—it just requires patience, proper treatment, and evidence-based strategies.
The safest and most effective long-term approach to sleep problems in recovery is Cognitive Behavioral Therapy for Insomnia (CBT-I), the gold standard treatment proven more effective than medication for chronic insomnia with no side effects or risks. CBT-I addresses thoughts and behaviors perpetuating insomnia through sleep restriction therapy, stimulus control re-associating bed with sleep, and cognitive restructuring reducing sleep anxiety. Additional evidence-based non-medication strategies include comprehensive sleep hygiene with consistent sleep/wake schedule even on weekends, dark cool bedroom (60-67°F), no screens 1-2 hours before bed, no caffeine after 2pm, regular exercise but not close to bedtime, and relaxing bedtime routine; mindfulness and relaxation techniques including progressive muscle relaxation, 4-7-8 breathing, body scan meditation, and yoga nidra; treating underlying conditions like anxiety, depression, PTSD, chronic pain, and sleep apnea; exercise programs proven to improve sleep quality; and light exposure therapy with morning sunlight. When medication is necessary, non-addictive options safe for recovery include trazodone (antidepressant commonly used for sleep), mirtazapine (antidepressant with sedating effects), low-dose doxepin (antihistamine), and hydroxyzine (anti-anxiety antihistamine). AVOID in recovery: benzodiazepines (Xanax, Valium, Ativan, Klonopin), Ambien and Lunesta (Z-drugs with addiction potential), and barbiturates. At Nova Transformations in Charlotte, we integrate comprehensive sleep treatment into addiction care using CBT-I, mindfulness training, medication management with safe non-addictive options, treatment of co-occurring conditions through our dual diagnosis program, and lifestyle interventions.

Sleep improvement in recovery follows a general timeline, though individual experiences vary significantly based on substance used, duration of use, and individual factors. In the first 1-2 weeks (acute withdrawal), sleep is typically at its worst with severe insomnia, night sweats, nightmares, and frequent awakening being common across most substance withdrawals—this is the most challenging period requiring maximum support. During weeks 2-8 (early recovery), sleep gradually begins improving as acute withdrawal subsides, sleep architecture starts normalizing, and with good sleep hygiene practices noticeable improvements occur, though sleep remains disrupted and patience is critical during this phase. At 2-6 months (ongoing recovery), significant sleep improvements become evident with sleep duration and quality steadily increasing, REM and deep sleep cycles restoring, reduced nighttime awakening, and the brain continuing to heal, though some sleep disturbances may persist. By 6-12+ months (long-term recovery), for most people sleep approaches or reaches normal levels, natural sleep-wake cycles are restored, and with continued good sleep hygiene and treatment of co-occurring conditions, sleep quality can be better than during active use. Important factors affecting timeline include type of substance with stimulant recovery often taking longer for sleep normalization, benzodiazepine withdrawal potentially causing prolonged sleep issues, and opioid users experiencing months of disrupted sleep; severity and duration of addiction; co-occurring mental health conditions like anxiety, depression, or PTSD prolonging sleep problems; sleep hygiene practices with good practices accelerating improvement; underlying sleep disorders like sleep apnea requiring separate treatment; and stress and life circumstances. The key message is that sleep WILL improve with sustained sobriety, but patience is essential—expecting perfect sleep immediately sets unrealistic expectations leading to frustration and potential relapse. At Nova Transformations, we support clients through this timeline with evidence-based interventions, realistic expectations, encouragement during difficult early phases, and comprehensive treatment addressing all factors affecting sleep. Recovery is possible, and restful sleep will return.
