Nighttime is not just a time for rest. It is also indicative of our state of health. “Many nocturnal symptoms are initially mild”explains Dr. Gérald Kierzek, emergency physician. “But when they repeat, worsen or combine, they can reflect a cardiac, respiratory, neurological, hormonal or psychiatric disease. Hence the usefulness of taking them seriously. The issue is not only the quality of sleep, because these disorders can lead to daytime sleepiness, reduced alertness, an increased risk of accidents, but also, in the long term, cognitive and psychological alteration.
Waking up out of breath: a sign that should never be trivialized
Waking up in the middle of the night with a feeling of lack of air, sometimes accompanied by chest tightness, coughing or wheezing, is never trivial when it is a repeated phenomenon. This type of sudden awakening can be a sign of heart failure, especially when associated with swelling of the ankles, rapid weight gain or palpitations.
It can also reveal obstructive sleep apnea syndrome, nocturnal asthma, pulmonary pathology or severe gastroesophageal reflux with micro-inhalations.
“The risk is cardiac or respiratory decompensation, but also significant fragmentation of sleep.”alerts the doctor. So go to your healthcare professional.
Snoring loudly and often: much more than just an inconvenience
Chronic snoring, especially when it is loud and daily, should also be of concern. “What worries you are the breathing pauses observed by those around you, waking up feeling suffocated, morning headaches or persistent fatigue during the day.specifies Dr. Kierzek.
In many cases, these symptoms suggest sleep apnea, caused by obesity, alcohol in the evening, certain medications or ENT abnormalities. Untreated, apnea exposes you to an increased risk of hypertension, stroke, heart attack, diabetes and accidents linked to drowsiness.
Sleepwalking and unusual nocturnal behaviors
Talking while sleeping, walking at night or adopting complex behaviors during sleep can seem impressive but sometimes remain benign in children. On the other hand, in adults, repeated sleepwalking or violent gestures should alert.
“Certain nocturnal behavior disorders can be linked to parasomnias, but also, more rarely, announce neurological diseases” explains the doctor. There is also an immediate risk: that of injuries, falls or endangering those around you, with a strong impact on family life.
Chronic nightmares: when sleep becomes anxiety-provoking
Having an occasional nightmare is normal. But when these occur once or twice a week, with anticipatory fear before going to sleep, they can reflect an anxiety or depressive disorder or post-traumatic stress.
Certain medications or substance use can also make these episodes worse. “The danger is psychological exhaustion and resorting to alcohol or sleeping pills to try to sleep, which often aggravates the problem.emphasizes Dr. Kierzek.
Bruxism and repeated nocturnal waking: signals often overlooked
Grinding your teeth at night, with jaw pain or headaches upon waking, is often linked to stress or anxiety, but can have significant dental consequences. Likewise, getting up several times a night to urinate, especially in adults or the elderly, can reveal a prostate or cardiac pathology or poorly controlled diabetes.
“These nocturnal risings also expose you to the risk of falling and loss of autonomy,” calls back the doctor.
Night sweats, cramps, sleep paralysis: other signs to watch for
Repeated night sweats, especially when accompanied by fever, fatigue or weight loss, should lead to medical advice. Nighttime cramps, restless legs, or frequent, anxiety-inducing sleep paralysis may also signal an underlying disorder that requires treatment. And should be mentioned to your doctor.
When, who and why consult?
“When a sign is repeated at night, it is never a small detail”, insists Dr Gérald Kierzek. A consultation often makes it possible to make a diagnosis, secure sleep and prevent sometimes serious complications, such as accidents, falls, strokes or heart attacks.
In this case, the first contact remains the treating physician, who may refer you to a sleep specialist, a cardiologist, a pulmonologist, a neurologist or a mental health professional depending on the symptoms.
In other words, talking to a doctor is often the first step in finding truly restorative nights and protecting your health in the long term.
