Asthma and Sleep: Why Nighttime Symptoms Matter?

Waking up coughing at night or feeling tightness in the chest in the early morning is a common experience for people with asthma. However, this should not be considered "normal." Nighttime symptoms are one of the most important signs that asthma is not fully under control.

Why does asthma worsen at night?

• The body's daily rhythm: At night and in the early morning, the diameter of the airways naturally narrows slightly, and inflammation increases. This change is felt more pronounced in individuals with asthma.

• Bedroom allergens: Dust mites are found in high concentrations in pillows, duvets, and mattresses. Pets sleeping in the bedroom also increase exposure.

• Sleeping position: When lying on your back, nasal discharge can drain into your throat and trigger a cough.

• Gastric reflux: When lying down, stomach acid reflux can worsen coughing and asthma symptoms in some people.

• Cool room air: If the room gets cold at night, it can irritate the airways.

• Reduced effectiveness of the medication: Skipping the evening dose or inadequate treatment can lead to nighttime symptoms.

The effects of insomnia

Poor sleep isn't just about tiredness. It can cause difficulty concentrating during the day, decreased performance at school and work, irritability, and mood swings. In children, it can manifest as behavioral problems. Parents' sleep is also often disrupted.

Making the bedroom asthma-friendly

• Wash the bedspreads in hot water once a week.

• If you have a dust mite allergy, consider using mite-proof covers for your pillows and mattress.

• In the bedroom, reduce the number of dust-collecting items like carpets, heavy curtains, and plush toys.

• Make sure pets don't enter the bedroom.

• Ventilate the room regularly, but don't let the room temperature drop too low.

• Smoking and strongly scented products should not be used in the bedroom.

Good sleep habits

• Try to go to bed and wake up at the same time every day.

• Avoid heavy meals before bedtime; if you have reflux, eat dinner a few hours before going to bed.

• Reduce screen time before bedtime.

• If you have your evening medication, take it regularly.

• Keep your soothing inhaler by your bedside.

When should you consult a doctor?

If you wake up one or more nights a month due to asthma, discuss this with your doctor. Your treatment may need to be reviewed. Also, if you experience symptoms such as loud snoring, pauses in breathing during sleep, or waking up feeling unrested in the morning, it may be helpful to be evaluated for sleep apnea, which can accompany asthma.

Don't forget

A person with well-controlled asthma should be able to sleep uninterruptedly at night. Seeking solutions instead of accepting nighttime symptoms can change both your nights and your days.
