Shortness of Breath at Night

Nighttime asthma, with symptoms like chest tightness, shortness of breath, cough, and wheezing at night, can make sleep impossible and leave you feeling tired and irritable throughout the day. These problems may impact your overall quality of life and make it harder to manage your daytime asthma symptoms.

Shortness of Breath at Night

Nighttime or nighttime asthma is really major. It requires a proper asthma medical diagnosis and efficient asthma treatment.

Nighttime Asthma and Sleep Disturbance

The chances of experiencing asthma symptoms are greater during sleep. Nocturnal wheezing, cough, and problem breathing prevail yet potentially unsafe. Numerous medical professionals typically underestimate nocturnal asthma or nighttime asthma.

Studies reveal that a lot of deaths related to asthma symptoms such as wheezing take place during the night.

Nocturnal Asthma Causes

The exact factor that asthma is even worse during sleep are not known, however there are explanations that include increased direct exposure to irritants; cooling of the airways; being in a reclining position; and hormonal agent secretions that follow a circadian pattern. Sleep itself might even cause modifications in bronchial function.

Increased Mucus or Sinusitis

During sleep, the respiratory tracts tend to narrow, which might cause increased airflow resistance. This may trigger nighttime coughing, which can cause more tightening up of the airways. Increased drainage from your sinuses can likewise set off asthma in extremely sensitive respiratory tracts. Sinusitis with asthma is rather common.

Internal Triggers

Asthma issues may occur during sleep, in spite of when the sleep period is happening. Individuals with asthma who deal with the night shift might have breathing attacks throughout the day when they are sleeping. A lot of research suggests that breathing tests are worse about four to six hours after you go to sleep. This suggests there may be some internal trigger for sleep-related asthma.

Reclining Position

Lying in a reclining position may likewise predispose you to nighttime asthma issues. Lots of elements might cause this, such as accumulation of secretions in the airways (drain from sinuses or postnasal drip), increased blood volume in the lungs, decreased lung volumes, and increased respiratory tract resistance.

Air Conditioning

Breathing chillier air at night or sleeping in an air‑conditioned bedroom may also cause loss of heat from the respiratory tracts. Respiratory tract cooling and wetness loss are very important triggers of exercise‑induced asthma. They are also linked in nighttime asthma.


If you are frequently troubled with heartburn, the reflux of stomach acid up through the esophagus to the throat might promote a bronchial convulsion. It’s even worse when lying down or if you take medications for asthma that relax the valve in between the stomach and esophagus. Sometimes, acid from the stomach will irritate the lower esophagus and result in constriction of your airways. If stomach acid supports to your throat, it may leak down to the trachea, air passages and lungs, leading to a severe reaction. This can include air passage inflammation, increased mucus production, and air passage tightening. Taking care of GERD and asthma with appropriate medications can typically stop nighttime asthma.

Late Phase Response

If you are exposed to an irritant or asthma trigger, the opportunities are excellent that air passage obstruction or allergic asthma will happen quickly afterward. This acute asthma attack ends within one hour. About 50% of those who experience an instant response likewise have a 2nd phase of respiratory tract obstruction within three to eight hours of exposure to the irritant. This phase is called the late stage response, and it is defined by a boost in respiratory tract responsiveness, advancement of bronchial swelling, and a more prolonged duration of respiratory tract obstruction.

Numerous research studies report that when irritant exposure takes place in the evening rather of in the early morning, you are more vulnerable to having a late phase response and are more likely to have among higher severity.

Hormonal agents

Hormonal agents that distribute in the blood have well‑characterized circadian rhythms that are seen in everyone. Epinephrine is one such hormonal agent, which puts in crucial impacts on the bronchial tubes. This hormone assists keep the muscle in the walls of bronchi relaxed so the airway stays broad. Epinephrine likewise reduces the release of other compounds, such as histamines, which cause mucus secretion and bronchospasm. Your epinephrine levels and peak expiratory flow rates are lowest at about 4:00 a.m., while histamine levels tend to peak at this same time. This decline in epinephrine levels may predispose you to nighttime asthma during sleep.

How Is Nocturnal Asthma Treated?

There is no remedy for nighttime asthma, but everyday asthma medications, such as breathed in steroids, are very efficient at reducing inflammation and avoiding nighttime symptoms. Since nocturnal asthma or nighttime asthma might take place anytime during the sleep period, asthma treatment should be sufficient to cover these hours. A long-acting bronchodilator delivered in an asthma inhaler can be effective in avoiding bronchospasm and symptoms of asthma. If you suffer from nighttime asthma, you might also gain from a long-acting breathed in corticosteroid. If you suffer with GERD and asthma, ask your doctor about medication that lowers acid production in the stomach. Avoidance of potential allergic reaction activates such as allergen, animal dander, or plumes in a down comforter may likewise be really handy in avoiding allergic reactions and asthma and nighttime asthma attacks.

In addition, utilizing your peak flow meter, you can keep track of how your lung function is changed throughout the day and night. As soon as you observe this transformed pattern of lung function, talk with your doctor about a plan to resolve your nighttime asthma symptoms. According to your kind of asthma and asthma severity (moderate, moderate, or severe), your doctor can prescribe treatment to assist you solve your nighttime asthma symptoms so you can sleep like a baby.
