Sleep deprivation: A serious threat to the heart, memory, and mood

On July 31, 2025, TVA Nouvelles published an alarming report: nearly 50% of Quebecois suffer from poor sleep, which can lead to fatigue, cognitive issues, irritability - and even major cardiovascular risks. 

Main effects of sleep deprivation:

• Loss of concentration and memory impairment: During sleep, the brain consolidates memories and clears out toxins. Without this, cognitive performance declines. 
• Mood disorders: Irritability, bad temper, and increased vulnerability to psychiatric disorders. 
• Cardiovascular risks: High blood pressure, heart rythm disturbances, cardiac and metabolic diseases such as diabetes, and even increased risk of dementia in older adults. 

Public health specialists warn that just three nights of insufficient sleep can visibly affect the heart: elevated heart rate, irregular rhythms, and increased blood pressure. 

Why bring up sleep apnea in relation to this report?

Obstructive Sleep Apnea (OSA) is often overlooked, yet directly contributes to poor sleep quality and the resulting serious health symptoms. 

Repeated breathing pauses during the night reduce blood oxygen levels, activate the nervous system, cause frequent micro-awakenings, and trigger the release of stress hormones like adrenaline. This puts extra strain on the heart and promotes hypertension,  arrhythmia, and even heart attacks. 

Furthermore, untreated OSA affects memory, focus, mood, and overall health. 

What we offer:

• Simple home screeing using a cardiorespiratory polygraphy test. 
• Expert analysis  by a pulmologist and sleep specialist, with clear interpretation of results. 
• Personalized CPAP treatment, with professional guidance from qualified clinicians. 
• Ongoing free follow-ups to ensure treatment effectiveness and optimize daily comfort. 

Conclusion: Take action today for better sleep tomorrow

The TVA confirms what science and clinical experience have long shown: insufficient sleep is not harmless. It impacts the heart, brain, and mood - and sleep apnea is often the underlying cause.
