Does it Really Matter When I Go Outside?

It's All About Timing

Avoiding pollen can be a little like dodge ball

Planning your day around pollen levels may feel a bit cumbersome. But it’s important to know that the amount and type of pollen in the air can vary from hour to hour and from day to day. An hour outside in “very high” pollen conditions can be equivalent to 10 hours of exposure in “moderate” conditions. So, yes, it does matter when you go out. If you can figure out what you’re allergic to and when that pollen count is high, you can stay inside during those hours and avoid triggering your hay fever.

Since Pollen Sense is the only app that reports hourly data from real sensors, you can only get that information here. 

Pollen Counts

On most days, pollen counts rise during the morning, peaking around the middle of the day and then gradually falling during the afternoon and evening. Usually, you’ll find the lowest pollen counts early in the morning or late in the afternoon or early evening.

However, this is NOT always the case and the pollen count can vary based on a multitude of factors. Sometimes the highest pollen levels are in the late afternoon or even 10 pm at night.

On some days, the pollen count will remain extremely high for the entire 24 hour period, so it may be best to stay inside all day on that particular day. Further, things like the weather and other environmental factors can drastically affect the amount of pollen in the air. For example, a windy day can stir up pollen and keep it high, while rain can temporarily wash all of the pollen out of the air.

How Can I Know When To Go Out?

The best way to figure out what you're allergic to and when you should avoid going out is by checking the Pollen Sense app and logging your symptoms in the Coach. We’ll let you know which types of allergens are in the air and what the pollen count is for each one. The Coach will help you track how you felt and what the levels of the different pollen types were so you can identify what allergens cause you the most suffering. Use the Pollen Wise app to plan your day to avoid allergens and unnecessary suffering.

Timing your activities to avoid high pollen exposures can improve how you feel.
