Snoring that gradually gets louder or more frequent usually signals a physical change in the throat, not just a bad habit. The most common culprits are weight gain, aging, nasal congestion, and alcohol use, and in many cases several of these factors compound at once. The good news is that most of these causes are identifiable and treatable. The important thing is figuring out which ones apply, because worsening snoring can also be an early sign of obstructive sleep apnea.
His Throat Is Physically Changing With Age
Even if your husband hasn’t gained weight or changed any habits, aging alone can make snoring worse. The soft palate, the tissue at the back of the roof of the mouth, gets longer and thicker over time while also becoming less stiff. A longitudinal study that followed young adults over 32 years found their soft palates had grown measurably longer and thicker, and the space at the back of the throat had narrowed. That’s a recipe for louder vibration every time air passes through during sleep.
The muscles that keep the airway open weaken with age too. The tongue’s main stabilizing muscle becomes less responsive to the negative pressure that occurs when you breathe in during sleep. In younger people, this muscle reflexively tightens to keep the airway from collapsing. In older adults, that reflex is significantly blunted. Fat deposits around the airway also increase with age, even in people whose overall weight stays stable, further crowding the space air needs to flow through.
Weight Gain Is the Most Common Driver
Even a modest increase in weight can have an outsized effect on snoring because fat doesn’t distribute evenly. Some of it deposits around the neck and throat, pressing inward on the airway. A neck circumference greater than 17 inches in men is a recognized risk factor for obstructive sleep apnea. You don’t need to be significantly overweight for this to matter. A gain of 10 to 15 pounds, depending on where it settles, can be enough to turn occasional snoring into a nightly problem.
This is one of the most actionable causes. Studies consistently show that losing even 10% of body weight can meaningfully reduce snoring severity. If your husband’s snoring worsened around the same time his weight crept up, the connection is likely direct.
Allergies and Nasal Congestion
If the snoring is seasonal or has worsened since moving to a new home, allergies may be the trigger. Allergic rhinitis, the type that causes a stuffy or runny nose, is a common but often overlooked contributor to louder snoring. When the nasal passages are even partially blocked, the body compensates by breathing through the mouth. Mouth breathing pulls air through the narrowest part of the throat at higher velocity, which vibrates the soft tissues more aggressively.
People with moderate to severe allergic rhinitis are also more likely to develop sleep apnea. Dust mites in bedding, pet dander, and mold in the bedroom are frequent offenders. If your husband wakes with a stuffy nose most mornings, treating the congestion (with antihistamines, nasal sprays, or allergen-proof pillow covers) can reduce snoring noticeably within days.
Alcohol, Medications, and Sleep Position
Alcohol relaxes the muscles of the throat more than normal sleep does, and the effect is dose-dependent. Even two drinks in the evening can turn a mild snorer into someone who rattles the walls. If your husband’s drinking habits have increased, or if he’s having drinks closer to bedtime than he used to, that alone could explain the change.
Certain medications have a similar effect. Muscle relaxants, sedatives, and some anxiety medications all reduce muscle tone in the upper airway. If a new prescription coincided with louder snoring, it’s worth mentioning to his doctor.
Sleep position matters too. Back sleeping lets gravity pull the tongue and soft palate backward into the airway. Many people shift toward more back sleeping as they age or gain weight because side sleeping becomes less comfortable. A simple positional change, using a body pillow or a wedge to encourage side sleeping, can reduce snoring intensity in people whose snoring is position-dependent.
When Snoring Becomes Sleep Apnea
Worsening snoring is one of the hallmark signs of obstructive sleep apnea, a condition where the airway repeatedly collapses during sleep. The key distinction is what happens between the snores. If you notice your husband stops breathing for several seconds and then gasps, chokes, or snorts before resuming, that pattern strongly suggests apnea rather than simple snoring.
Other signs to watch for: excessive daytime sleepiness despite a full night in bed, morning headaches, difficulty concentrating, and waking up feeling unrefreshed. Obstructive sleep apnea has been linked to higher rates of high blood pressure, stroke, and coronary artery disease. There’s also evidence it can cause structural changes in the heart that increase the risk of heart failure. These aren’t distant, theoretical risks. Untreated moderate-to-severe sleep apnea raises cardiovascular risk substantially over years.
A widely used screening tool asks about eight risk factors: loud snoring, daytime tiredness, observed breathing pauses, high blood pressure, a BMI over 35, age over 50, neck circumference over 17 inches, and male sex. If three or more apply, there’s a meaningful likelihood of obstructive sleep apnea, and a sleep study is the logical next step. Many sleep studies can now be done at home with a portable monitor rather than requiring a night in a sleep lab.
What Actually Helps
The right approach depends on what’s driving the change. For weight-related snoring, even gradual weight loss can produce significant improvement. For congestion, treating the underlying allergy or irritation often works quickly. For positional snoring, side-sleeping aids or elevating the head of the bed by a few inches can help.
If sleep apnea is confirmed through a sleep study, the standard treatment is a CPAP machine, which delivers gentle air pressure through a mask to keep the airway open. Newer devices are smaller and quieter than older models, and compliance tends to improve once people experience how much better they feel after consistent use. Oral appliances that reposition the lower jaw are an alternative for mild to moderate cases.
The most important thing is not to normalize worsening snoring as just “something that happens.” It’s a signal that something has changed physically, and identifying that change is the first step toward quieter, healthier sleep for both of you.
