For many, spring and summer mean a longed-for return of sun, warmth, and greenery. But for millions of people in Sweden and around the world, it also means something entirely different – namely, pollen season. That time of year when the air is filled with microscopic particles that can cause a range of troublesome symptoms: runny nose, itchy eyes, fatigue, and sneezing. But what exactly is pollen, why do our bodies react so strongly, and what can be done to alleviate the symptoms?
What is pollen and why do we react to it?
Pollen are microscopic grains produced by plants to fertilize other plants of the same species. They are essential for plant reproduction and are often spread through the air by wind, or by insects. For people without allergies, pollen is harmless. But for those suffering from pollen allergy, these tiny particles can trigger an overreactive immune system.
When a pollen allergy sufferer inhales pollen, the immune system misinterprets these particles as dangerous invaders. This leads the body to release histamine and other substances that cause inflammation and typical allergy symptoms. This reaction is called an allergic reaction – in this case, specifically to pollen.
Different types of pollen
There are different types of pollen that cause allergic reactions, depending on the growing season and plant species:
- Tree pollen: Common in spring (March to May). Common trees include birch, alder, hazel, and oak. Birch pollen is particularly allergenic in Sweden.
- Grass pollen: Primarily active in early summer and summer (May to July). Various types of grasses can cause allergies, such as timothy, orchard grass, and Kentucky bluegrass.
- Mugwort pollen: Appears later in the summer (July to September). Mugwort is an herbaceous plant that grows wild and causes late allergy symptoms.
Each type of pollen has its specific season, and some people may be allergic to several types – which means a long period of symptoms.
How is pollen spread?
Pollen dispersal occurs primarily through the air. Some plants, like birch, spread large quantities of pollen over long distances. Wind conditions, temperature, and precipitation affect the concentration in the air. Dry and windy days are often the worst for pollen allergy sufferers, as pollen has free rein to swirl around in the atmosphere.
Why do some react and not others?
That some people develop pollen allergy while others are completely symptom-free has several explanations. Genetics play a major role – if one or both parents have allergies, the risk increases. But environmental factors, such as exposure during childhood, hygiene levels, and air pollution can also influence the development of allergies.
There is also an interesting theory called the "hygiene hypothesis," which suggests that children who grow up in very clean environments are at greater risk of developing allergies because their immune systems are not trained in the same way.
Immunological reaction – what happens in the body?
When pollen enters the nose or eyes of an allergic person, the body identifies it as a threat. This activates mast cells, which in turn release histamine – a substance that causes inflammation in the mucous membranes. The result? Sneezing, nasal congestion, watery eyes, and sometimes even itching in the throat or ears.
For some, the reaction can be so strong that it affects sleep, concentration, and quality of life. In some cases, allergic asthma also develops, where pollen affects not only the upper airways but also the bronchi, leading to breathing difficulties.
Common and unusual symptoms of pollen allergy
Pollen allergy is best known for its classic symptoms: sneezing, runny nose, and itchy eyes. But the symptoms can be much more varied than that – both in terms of intensity and which parts of the body are affected. It is therefore important to understand the full spectrum of reactions that pollen can cause to correctly diagnose and treat the allergy.
The most common symptoms – classic hay fever
1. Sneezing
One of the most typical signs of pollen allergy is repeated sneezing, especially in series. These are triggered when pollen particles irritate the nasal mucous membranes.
2. Runny or stuffy nose (rhinitis)
Nasal symptoms are central to pollen allergy. For some, the nose is constantly running with clear fluid, while others feel completely congested, making it difficult to breathe through the nose. Many switch between these two extremes during the day.
3. Itchy and watery eyes (conjunctivitis)
Itchy eyes that water and become red are another clear sign. It is common for these symptoms to occur simultaneously with nasal symptoms. The eyes can also become light-sensitive.
4. Fatigue and difficulty concentrating
Many with pollen allergy report feeling constantly tired or "brain fog" during pollen season. This can be due to both the allergy itself and the fact that sleep is affected by nasal congestion or itching.
5. Itching in the throat, palate, and ears
Another common effect is itching in the mouth, especially in the palate and throat. This can also feel like a kind of tickling discomfort in the ears. It occurs when pollen particles irritate the mucous membranes in these areas.
6. Cough
Cough can be caused by mucus from the nose dripping down into the throat (so-called postnasal drip), or by irritated lungs.
7. Worsening asthma
People with asthma may notice that their symptoms worsen during pollen season. This can include wheezing, coughing, chest tightness, and breathing difficulties.
Less known symptoms – when pollen affects the whole body
1. Headache
Pollen allergy can sometimes trigger tension headaches or migraine-like complaints. This is especially common with prolonged nasal congestion, which creates pressure in the sinuses.
2. Sleep disturbances
Stuffy nose and cough at night can make it difficult to sleep. Poor sleep in turn can worsen other symptoms, such as fatigue and mood swings.
3. Mood changes
Irritation, low mood, and reduced quality of life are reported by many pollen allergy sufferers. This is not just about the physical impact, but also about the allergy limiting everyday life – avoiding being outdoors, exercising less, and sleeping worse.
4. Ear problems
In some, the allergy can cause a feeling of blocked ears, or even affect balance. This is because the mucous membranes in the ear canals can also swell.
5. Skin rashes and eczema
Although less common, pollen allergy can affect the skin – especially in those who already have atopic dermatitis (eczema). Some get rashes or itching with direct contact with pollen.
6. Oral Allergy Syndrome (OAS)
OAS is a condition where one reacts to certain fruits, vegetables, and nuts, because their proteins resemble those in certain pollen types. Example: people with birch pollen allergy may react to apples, carrots, or hazelnuts with itching in the mouth or throat.
The difference between a cold and pollen allergy
Since pollen allergy often causes symptoms similar to a cold, it is easy to confuse them. But there are some important differences:
| Symptom | Cold | Pollen Allergy |
|---|---|---|
| Fever | Common | Uncommon |
| Sneezing | Moderate | Intense, in series |
| Nasal congestion | Common | Common |
| Watery eyes | Uncommon | Common |
| Itching (eyes/nose) | Rare | Very common |
| Duration of symptoms | 5–10 days | Several weeks or months |
| Worsens outdoors | No | Yes, especially with high pollen count |
When should you seek medical care?
Most people with pollen allergy manage with over-the-counter medications and self-care. But sometimes medical help is required, especially if:
- Symptoms severely affect quality of life
- Common allergy medications don't help
- You suspect you have allergic asthma
- You experience severe reactions to certain foods (may indicate cross-allergy)
In these cases, an allergy investigation can be performed with blood tests or prick tests, and the doctor may suggest other treatments such as allergy vaccination (hyposensitization).
How to relieve pollen allergy – treatment, natural methods, and smart lifestyle choices
Pollen allergy doesn't have to ruin spring and summer. With the right strategies, symptoms can be significantly alleviated – in some cases to the extent that they are barely noticeable. Treatment can involve medication, but also changes in everyday life, diet, and how one spends time outdoors. In this chapter, we will cover everything you need to know to take control of your pollen allergy.
Medication for pollen allergy – what works?
There is a wide range of medications to treat pollen allergy, both over-the-counter and prescription. Many work by blocking histamine or reducing swelling in the mucous membranes.
1. Antihistamines
Antihistamines are the first-line treatment for most people with mild to moderate allergies. They come in tablet form, nasal sprays, or eye drops.
- Examples of common antihistamine tablets: Desloratadine (Aerius), Loratadine, Cetirizine (Zyrtec)
- Effect: Reduces sneezing, runny nose, itching, and eye discomfort.
- Side effects: The newer generations are often non-sedating, but some can still cause drowsiness.
2. Corticosteroid nasal sprays (nasal steroids)
For moderate or severe allergies, corticosteroid-based nasal sprays are often most effective. They reduce inflammation in the nasal mucous membrane.
- Examples: Nasonex, Flutide, Mometasone
- Effect: More effective than antihistamines for nasal congestion.
- Important: Often takes a few days to reach full effect – start early in the season!
3. Eye drops with antihistamines or cromoglicate
Itchy and red eyes are best treated with local eye drops.
- Examples: Livostin, Lomudal
- Use: Can be taken as needed or preventively.
4. Leukotriene antagonists
An alternative or supplement to antihistamines, especially with an asthma component.
- Example: Montelukast (Singulair)
- Benefit: Can help both respiratory and nasal symptoms.
5. Allergy vaccination (hyposensitization)
For severe allergies that do not respond to medication, allergy vaccination may be considered. This involves gradually accustoming the body to the allergen.
- Duration: 3–5 years of treatment
- Form: Injections or tablets under the tongue (sublingual immunotherapy)
- Effect: Can significantly reduce the allergy – sometimes permanently
Natural treatment methods and supplements
For those who want to reduce medication use or combine treatment with milder methods, several natural alternatives exist. These do not always replace medication but can be a valuable addition.
1. Nasal rinsing with saline solution (neti pot/nasal douche)
Daily nasal rinsing with physiological saline solution washes pollen away from the mucous membranes and reduces irritation.
- Effect: Relieves nasal congestion, reduces need for medication
- How: Use a neti pot and lukewarm water with salt
2. Honey (locally produced)
Some claim that locally produced honey can build tolerance to pollen – similar to allergy vaccination. The evidence is unclear, but many experience mild relief.
3. Probiotics and gut health
New research suggests that gut flora plays a role in allergies. Strengthening the gut with probiotics (yogurt, fermented foods) can help the immune system balance its reactions.
4. Acupuncture
Some studies show that acupuncture can alleviate allergy symptoms, especially nasal congestion and sneezing.
5. Essential oils
Eucalyptus and peppermint in a diffuser can open up airways. However, people with asthma should be careful.
Lifestyle changes that make a difference
Changing certain habits can significantly reduce exposure to pollen. Here are the most important lifestyle tips to prevent discomfort:
1. Keep track of the pollen forecast
Follow daily pollen forecasts via apps, SMHI, or pollenkoll.se. Avoid outdoor activities when levels are highest – often in the morning and during dry weather.
2. Change clothes and shower after outdoor activities
Pollen sticks to hair and clothes. Shower and change immediately when you come home to reduce indoor exposure.
3. Do not dry laundry outdoors
Sheets and clothes dried outdoors can collect a lot of pollen, which worsens symptoms at night.
4. Sleep with windows closed
Keep windows and doors closed, especially in the morning. Use pollen filters in ventilation if possible.
5. Use an air purifier
Air purifiers with HEPA filters reduce the amount of pollen in indoor air.
6. Avoid being near grassy areas, meadows, and birch avenues
During high pollen levels, choose urban environments or coastal areas where pollen counts are lower.
7. Sunglasses and face mask outdoors
Sunglasses protect the eyes, and a face mask can reduce the amount of pollen you breathe in – especially effective during intense periods.
The role of technology – apps and smart solutions
There are now several digital tools that can simplify life for pollen allergy sufferers:
- Pollen apps: Apps like Pollen (by ALK), Klart.se, and SMHI show current levels and provide personal warnings.
- Air purifiers: HEPA filters in bedrooms or living rooms can reduce the amount of pollen particles in indoor air.
- Smartwatch with health app: Some apps allow you to log symptoms and compare them with pollen levels – perfect for seeing patterns and optimizing treatment.
Living with pollen allergy year-round
Pollen allergy is often considered a seasonal problem. But for many, it is a lifelong struggle that affects several months each year, year after year. As the climate changes and the pollen season becomes longer, it is more important than ever to view the allergy from a holistic perspective. It is not just about alleviating symptoms for a few weeks – but about creating a life where the allergy has as little impact as possible.
There is no miracle cure. But by optimizing diet, exercise, sleep, stress management, and daily routines, one can build a stronger body and a calmer mind that copes better with allergies. Here's how.
Holistic health for allergy sufferers – why the whole body matters
Allergy is fundamentally an immunological phenomenon – the body overreacts to substances that are essentially harmless. But the immune system is affected not only by external factors like pollen – but also by your internal balance: gut flora, stress levels, diet, sleep, and physical health.
Therefore, it is wise to see allergy as something that can be influenced indirectly – by strengthening the body's resistance from several angles.
Diet that strengthens against allergy – what does research say?
Your diet largely affects your immune system. Inflammatory foods can worsen allergies, while anti-inflammatory diets can dampen the body's overreactions.
Anti-inflammatory foods that benefit allergy sufferers:
- Fatty fish (salmon, mackerel, sardines): Rich in omega-3, which dampens inflammation.
- Brightly colored vegetables (spinach, beetroot, broccoli): High levels of antioxidants.
- Berries (blueberries, raspberries, lingonberries): Strong natural antihistamines.
- Nuts and seeds (chia, flaxseed, walnuts): Good fatty acids and minerals.
- Probiotic foods (sauerkraut, kefir, yogurt): Strengthen gut immune function.
Foods that can worsen allergies:
- Processed foods and sugar
- Fast food and fried foods
- Alcohol (especially red wine, which can increase histamine production)
- Dairy products for some individuals (increased mucus production)
Some people may also react to cross-allergens in food, especially if they have birch pollen allergy. In such cases, for example, apple, pear, carrot, and hazelnut can cause mild allergic reactions in the mouth and throat (oral allergy syndrome, OAS). If this is the case, heat-treating the food can help – cooked apples or carrots rarely cause the same reaction.
Exercise during pollen season – should you exercise and how?
Exercising when you have allergies can feel like a paradox – especially outdoors, when the air is full of pollen. But physical activity is actually a key to better allergy tolerance.
Benefits of regular exercise:
- Strengthens the immune system
- Improves lung capacity
- Reduces stress and inflammation
- Promotes good sleep
Tips for allergy-friendly exercise:
- Exercise indoors during peak season, preferably in climate-controlled environments
- Choose cool times of day, such as evening or early morning
- Avoid grassy areas and woodlands during high pollen counts
- Use a pollen filter mask or buff to reduce inhalation
- Take allergy medication 30–60 minutes before exercise if you exercise outdoors
Finding the right balance is important – the body is more sensitive during high exertion, so listen to its signals. Avoid pushing yourself when pollen counts are extreme.
The role of sleep in allergy management
Sleep is crucial for recovery, hormones, and the immune system. But allergies significantly affect sleep – especially through nasal congestion, coughing, and itching that disrupt sleep quality.
Sleep strategies for allergy sufferers:
- Sleep with the window closed
- Change bedding often and avoid clothes that have been hung outside to dry
- Invest in allergen-proof mattress covers
- Use an air purifier in the bedroom (with HEPA filter)
- Rinse your nose before bed with a nasal irrigator
- Ensure that blood pressure, sugar, and stress are balanced – they affect sleep quality
A good night's sleep can often make the difference between a manageable and a difficult day during pollen season.
Mental health and stress management – an often overlooked aspect
Chronic allergies are not just a physical strain – they also take a mental toll. Many feel down, frustrated, or isolated when they have to avoid outdoor activities.
How stress affects allergies:
- Stress raises cortisol, which can ultimately disrupt the immune system
- Increased stress = increased inflammation = worse allergy symptoms
- Poor sleep due to allergies = even higher stress levels
Tools to reduce stress with allergies:
- Meditation or mindfulness – just 10 min/day makes a difference
- Breathing exercises (e.g., box breathing)
- Yoga – both calming and anti-inflammatory
- Journaling – helps process frustration
- Continuous contact with healthcare – provides security
It's not about "thinking away allergies" – but about giving the body the best possible conditions to stay balanced.
Interaction between body and environment – year-round considerations
Living with pollen allergies means being proactive – not just reacting when symptoms appear. It means building habits throughout the year:
- Eat well even during winter to prepare the body
- Exercise year-round, even low-intensity
- Plan vacations during high pollen periods
- Follow pollen forecasts year-round
- Ensure you get enough vitamin D and zinc, especially in winter
