How Pollen Meter Works

Real-Time Pollen Count Alerts Personalized to Your Health Conditions

High pollen doesn’t just cause sneezing. For people with hay fever, asthma, COPD, or allergies, it can trigger wheezing, breathlessness, and chest tightness. The NowPatient Pollen Meter tracks real-time tree, grass, and weed pollen levels in your area and sends personalized clinical alerts based on your specific conditions. Powered by NAB-certified data and your health profile, it tells you what the pollen count means for you – not just everyone else.

SERVICE GUIDE

How Pollen Meter Works

What Is the Pollen Meter Service?

The Pollen Meter Service is a visual indicator that tracks three different pollen types in your area: Tree, Grass, and Weed pollen. It uses a metric called Pollen Grains Per Cubic Metre (PPM) to show how much of each pollen type is in the air. The larger the number, the worse the pollen level. Risk levels are denoted as Low, Moderate, High, or Very High, and are also sensitive to your underlying health condition(s).

The Pollen Meter Service is accessible through three separate graphical Service Cards, one for each pollen type, all located in the ‘Personalised Insights’ section of your account homepage.

The Pollen Meter is classified as a Class I medical device under UK MDR 2002 regulations for its intended use. It is free for all registered NowPatient users.

How to Set Up the Pollen Meter

The three Pollen Meter Service Cards (Tree, Grass, and Weed) are located in the ‘Personalised Insights’ section of your account homepage. To activate them:

  1. Open the Pollen Meter Service Cards and select the ‘Unlock’ icon. This will take you to your health profile page.
  2. Update your health profile with your health conditions and click ‘Save’. This enables the service to send you personalized warnings based on your conditions.
  3. Enable location services on your device when prompted. This allows the Pollen Meter to access your current location for accurate local pollen readings.
  4. All three Pollen Meter Service Cards (Tree, Grass, Weed) will now activate and begin sending personalised clinical warnings based on the combination of pollen readings in your area and your health condition(s).

How Does the Pollen Meter Work?

The Pollen Meter uses NAB-certified and compliant data. NAB is the National Allergy Bureau. Pollen readings are refreshed each day. NowPatient’s AI algorithms trigger personalized warnings based on a combination of local pollen counts and your personal health condition(s). If the algorithm identifies a risk, you will receive:

  • A push notification with clinical advice on what to do next, sent directly to your device
  • An In-App notification viewable in the ‘Notifications’ section of your account homepage

You can also view any warning advisory at any time by selecting the ‘View Warning’ button on the relevant graphical Service Card.

Each Pollen Meter Service Card (Tree, Weed, Grass) will show you a reading and an associated risk level, if applicable. For example, if you are in an at-risk group such as someone with asthma or COPD, and the grass pollen count in your location is between 61 and 341, you will receive a HIGH RISK advisory notification describing the precautions you need to take to prevent the worsening of your condition.

For best use of the service, ensure your health profile is kept up to date with your health conditions.

How Can Pollen Affect Your Health?

Allergies to tree, grass, or weed pollen cause hay fever, which can affect lung conditions like asthma and COPD (chronic obstructive pulmonary disease). The NowPatient Pollen Meter sends you medically approved conditional warnings based on the pollen count in your location and your pre-existing medical conditions, if you have any.

The Three Types of Pollen

There are different types of pollen and you can be allergic to more than one kind across the year. Each type has its own season and health implications.

Tree Pollen

Tree pollen is a common hay fever trigger and is the first type of pollen released every year. Levels are usually highest from late March to mid-May. The most common tree pollen allergy is birch tree pollen, which affects about 20% of people with hay fever.

Grass Pollen

Grass pollen is the most common hay fever trigger and affects about 95% of people who have hay fever. Grass pollen is often highest between mid-May and July. There is evidence that when grass pollen levels are high, there is an increase in the number of people with asthma needing hospital treatment for their symptoms. There is also some evidence that suggests a link between high levels of grass pollen and increased numbers of COPD hospital admissions.

Weed Pollen

Hay fever can also be triggered by weed pollen, which is usually highest from the end of June until September.

Who Is in an At-Risk Group?

At-risk groups are defined as adults and children with heart or lung problems, who are at greater risk of symptoms. Follow your doctor’s usual advice about exercising and managing your condition.

It is possible that very sensitive individuals may experience health effects even on low pollen count days. Anyone experiencing severe symptoms should seek medical advice.

The following conditions are classified as at-risk for sensitivity to pollen counts:

  • Allergies
  • Asthma
  • Chronic Bronchitis
  • Chronic Obstructive Pulmonary Disease (COPD)
  • Hay Fever

When Should I See a Doctor?

If the pollen count is Moderate, High, or Very High and you are Asthmatic, have Allergies, COPD, or Bronchitis, you should make an appointment with your doctor if you observe any of the following worsening symptoms:

  • Feel wheezy
  • Feel breathless
  • Have a tight feeling in your chest
  • Are coughing more than usual
  • Have asthma and need to use your reliever inhaler (usually blue) three times a week or more
