Coping with Asthma During Winter

Coping with Asthma During Winter

Winter MaskAsthma sufferers face asthma triggers from many different fronts. Common cleaning products or even perfume can cause asthma attacks. Allergies to pet dander, pollen, mold, and dust mites can also induce asthma attacks. Even the weather itself can pose dangers to asthma sufferers, and the winter months are certainly no exception.

Cold Air Triggers Asthma

The cold air that winter brings can set off asthma attacks. Cold air is often directly responsible for the onset of asthma symptoms, but upper respiratory infections that are common in the wintertime can also cause asthma attacks. Although cold air in itself does not cause colds, as folk medicine (or your grandmother) may have suggested, cold air does affect the respiratory system in several ways:

  • Mucus transport - a thin layer of mucus, called the "mucus blanket," coats the entire respiratory system. The mucus, which rests on tiny hairs called cilia, protects the lungs from particles and organisms by trapping them. The mucus blanket is actually in constant motion and moves undesirable particles out of the respiratory system - when it's working properly. Chemicals, cigarette smoke, and - you guessed it - cold air can alter the effectiveness of the mucus blanket and make a person more vulnerable to infection. The stickiness of the mucus traps particles, and the fluidity of the mucus ushers them away from the lungs. Although it stimulates mucus production, cold air makes the mucus thicker. Thicker mucus means that inhaled particles are harder to remove from the respiratory system.
  • The nose - one function of the nose as it relates to respiratory health is to condition inhaled air and thereby protect delicate lung tissue. When you breathe in cold air, tiny blood vessels in your nose warm the air. Blood rushes to the nose, and nose tissues swell (this accounts for winter's red noses). Cold air also causes nose mucus to become thicker and more abundant. Hence, cold air can produce nasal congestion and stuffiness.
  • The lungs - despite the protection of the mucus blanket and the nose, cold air can still reach the lungs. When this happens, the lungs react by releasing histamine, which causes wheezing, especially in asthma sufferers.

In order to help protect your lungs from cold air that can lead to respiratory infections and/or asthma symptoms, experts recommend warming the air that you breathe. You can wear a scarf over your mouth when you need to walk for a short time in cold air. Cold weather masks are also a great option, especially if you need to be outside in the cold for a longer period of time.

Indoor Air Quality Is Worse During Winter

As asthma sufferers know, allergies can be one of the biggest triggers of asthma attacks. While pollen allergies are not much of a concern during the winter, poorer indoor air quality during winter months can spell danger for asthmatics. Closed doors and windows, sealed tightly against the cold, prevent air circulation, leading to higher concentrations of indoor allergens. On top of that, people spend more time indoors during the winter, and therefore more time surrounded by - and breathing in - indoor allergens. (Air quality is generally worse indoors than out in any season, but especially during winter.)

The Environmental Protection Agency (EPA) suggests that asthma sufferers "identify asthma triggers in your home" as well as figure out "ways to get rid of triggers in your home." Along with a recommendation to asthma-proof your home, the EPA states: "Triggers are a part of everyday life. Asthma attacks can be triggered by things like mold growing on your shower curtain or tiny dust mites that live in blankets, pillows, or your child's stuffed animals.

Fortunately, allergens such as mold, dust mites, and pet dander can be kept under control. Proper care to minimize exposure to these allergens could greatly reduce their impact as winter asthma triggers. Mold is especially likely to grow throughout the cold and wet winter months when there is extra moisture and less airflow in the house. Mold treatment should involve both the removal of existing mold spores and the prevention of new mold growth:

  • Cleaning surfaces that are affected by mold should be the first step. Mold and mildew removers such as M-1 House Wash, AllerMold, and Vital Oxide do a great job.
  • HEPA air purifiers are great for removing mold spores before they lead to new mold growth or are inhaled by you.
  • Pre-treat areas that are susceptible to mold growth, such as shower curtains, bathroom tiles, basements, or closets. Vital Oxide is a safe and effective mold and mildew remover that also inhibits the growth of new mold for up to seven months. M-1 Sure Cote also acts as a sealant to prevent mold re-growth.
  • As much as possible, allow moisture to escape from the home. If possible, open windows to allow shower or cooking steam to escape, or turn on air vents.

Dust mites and pet dander are also present in higher concentrations during the winter months. Therefore, they are even more likely to trigger allergy attacks, which in turn can lead to asthma problems. But as with mold, dust mite and pet dander allergens can be effectively dealt with through environmental control:

Taking control of the sources of poor winter indoor air quality will go a long way in keeping both allergy and asthma attacks at a minimum.

Combating Depression

With cold temperatures and less sunlight, winter is a time of particular vulnerability to depression. The Allergy & Asthma Advocate reports that depression rates among those with chronic diseases are significantly higher than in those without them. This is because chronic diseases such as asthma can greatly affect people's quality of life by preventing them from participating in routine activities or by making them feel helpless. Sadly, children are often the ones affected by such depression. Unable to play with other children, missing school, or waking up in the night unable to breathe can lead to feelings of isolation and poor self-esteem.

Typical rates of depression are around 12.7% in men and 21.3% in women, while asthmatics' rates of depression fall between 20% and 50%. The Allergy & Asthma Advocate states, "Research has also indicated that people with asthma who are depressed may not follow their asthma management plan, and that they may have difficulty adjusting their behaviors overall. Thus, one can get into a cycle whereby asthma symptoms lead to feelings of helplessness and depression, which then lead to poor self management of asthma, resulting in worsening of asthma symptoms."

Successful management of asthma is key to keeping depression at bay. In addition to medication regimens, allergen avoidance, and other asthma management programs, exercise has proven to be an effective way to help both asthma itself and tendencies toward depression.

Exercise Options for Those with Asthma

Exercise is an important component of an effective asthma treatment regimen because it helps to increase lung capacity. However, exercise could pose certain dangers for asthmatics. In fact, exercise-induced asthma is a leading cause of asthma symptoms. Precautions should be taken regarding what types of exercise are best for asthma sufferers. Exercising during winter months poses an extra challenge because of the effect that cold winter air has on the respiratory system.

One thing to keep in mind is to try to breathe through the nose as much as possible. Breathing through the mouth, especially taking in big gulps of air during aerobic exercise, doesn't allow the nose to perform its function of warming air before it reaches the lungs. Wearing a cold weather mask during outdoor exercise during the winter is a good idea; this way, asthma sufferers can still breathe normally (that is, through their mouths during exercise) without suffering the effects of cold air. Controlling the temperature of inhaled air through a cold weather mask greatly reduces the incidence of exercise-induced asthma.

The type of exercise done by asthma sufferers is also important to consider. Obstructive lung diseases such as asthma allow air into the lungs, but block it from leaving the lungs effectively. This leads to an excess of carbon dioxide in the lungs with no room for additional oxygen.

Studies published in Medicine & Science in Sports & Exercise have shown that exercising on a bicycle is a prime option for those with severe lung diseases. Running can greatly interfere with lung function; cycling, on the other hand, even hard cycling, allows asthmatics to get rid of excess carbon dioxide and take in the necessary amount of oxygen.

Note: It's important for asthmatic individuals to discuss exercise options with their doctors.

Should Asthma Sufferers Get a Flu Shot?

Simply put, yes. Winter time is peak flu season. The American Academy of Allergy, Asthma & Immunology (AAAAI) states that the flu "can cause a severe asthma attack, which can lead to potential complications including pneumonia and hospitalizations."

Since the flu infects millions of Americans every year, it's very likely that any given individual will be exposed to it at some point or another. The flu is a respiratory viral infection, so it's easy to see how it can lead to asthma attacks. There is no way to cure it, so prevention is the best remedy.

The flu is spread through the air and through contact. Sneezing and coughing by infected individuals spews germ-laced airborne particles into the air where they are often inhaled by nearby individuals. The flu can also live on many surfaces for up to two hours. In addition to taking the precaution of getting a flu shot, here are some things to keep in mind:

  • Wash hands frequently and avoid touching mucus membranes - the eyes, nose, or mouth.
  • As much as possible, steer clear of flu-harboring surfaces. Common flu-passing culprits include grocery cart handles, elevator buttons (especially the first floor button), escalator handrails, office desks, and hand-shakes.
  • If possible, avoid close contact with others such as on subways or in busses during flu season.
  • Boost your immune system by eating well, sleeping enough, reducing stress, and exercising.

Remember: People with allergies to egg or thimersol should not receive flu shots.

Although cold months do offer a respite from pollen allergens, winter is not time to get slack about controlling factors that could lead to asthma attacks. Cold air often contributes to the onset of asthma attacks, and other allergens such as dust, mold, and pet dander are often at extra high levels in the wintertime. The flu, which infects millions of Americans during the winter, also poses threats to asthma sufferers. But with proper knowledge of these winter dangers, as well as the resources to cope with them, asthma sufferers can help effectively reduce the number of winter-related asthma problems.
