One told the presenter: "Looks like I am staying inside again today," while another moaned: "I was fine in one room and went to another and my eyes were streaming and sore."
With hay fever season in full swing, there are a few easy, medication-free remedies to ease symptoms, including drying your clothes inside and keeping your windows closed.

"Pollen can be transferred into the home on laundry that's been aired outside," says Allergy UK nurse advisor, Holly Shaw.
"Keeping windows closed and not drying laundry outside during high pollen times, and showering when you return from being outside, will remove pollen from the skin and hair," she advises.
Adding honey to your diet could also help diminish hay fever symptoms, says pharmacist Parvinder Sagoo of SimplyMedsOnline. "The bee pollen in honey desensitises your body to other pollen, so increasing your daily honey intake could help you become less sensitive to pollen and as a result experience fewer seasonal allergy symptoms.
"I would advise a spoonful or two per day," Parvinder continues. "You could add it to your breakfast porridge or stir it into a mug of hot water and create a hot honey drink, you may want to also add lemon and ginger for extra immunity benefits."
