If you find yourself waking up in the middle of the night struggling to breathe, coughing, or wheezing, you might be dealing with nocturnal asthma. This condition affects millions of people worldwide, yet many don’t realize their nighttime breathing troubles have a name, or that effective management strategies exist.
Nocturnal asthma is a type of asthma where symptoms get worse at night, disrupting sleep and affecting your quality of life. And while it shares many of the same triggers and symptoms as daytime asthma, it comes with its own set of challenges.
Understanding Nocturnal Asthma
All asthma involves inflammation in the airways, which makes it harder to breathe. Nocturnal asthma is no different in that sense, but the timing of symptoms is what sets it apart. While typical asthma symptoms may strike during physical activity or after exposure to allergens, nocturnal asthma can seem to appear “out of nowhere.” This can happen even if your asthma seems well-controlled during the day.
This type of asthma also tends to flare up while you’re asleep, typically between midnight and 8 AM. Your airways naturally become more sensitive at night due to your body’s circadian rhythms, making you more susceptible to breathing difficulties even without clear external triggers.
Common Risk Factors
Several factors can increase your likelihood of experiencing nocturnal asthma:
- Environmental triggers in your bedroom, such as dust mites, pet dander, or mold, become more problematic when you’re spending 6-8 hours in close contact with them.
- GERD (acid reflux) often worsens when lying flat, and stomach acid can irritate your airways, triggering asthma symptoms.
- Hormonal changes affect your natural cortisol levels, which typically drop at night, reducing your body’s natural anti-inflammatory response.
- Temperature and humidity changes in your sleeping environment can also contribute to airway irritation.
Signs You Might Have Nocturnal Asthma
If you notice these symptoms regularly at night or early in the morning, nocturnal asthma might be the cause:
- Frequent nighttime coughing or wheezing
- Shortness of breath that wakes you up
- Chest tightness during sleep hours
- Feeling tired or ‘foggy’ despite adequate sleep time
- Needing to use your rescue inhaler more than twice per week at night
Taking Control of Your Nighttime Breathing
If you suspect nocturnal asthma is affecting your sleep, don’t suffer in silence. Work with your healthcare provider to develop a comprehensive management plan that may include adjusting your medication timing, identifying bedroom triggers, and optimizing your sleep environment. Your doctor may recommend using a nebulizer or a long-acting bronchodilator to help open your airways overnight.
