Consider hypoallergenic bedding
One point of consideration could be to invest in bedding specifically developed to protect against allergies.
Hypoallergenic bedding is made from material resistant to allergens, with memory foam and cotton being two examples of the stuff.
Keep your air clean
The warm and humid summer air is an ideal breeding ground for bacteria, dust mites and mould – all of which are allergens that could keep you up at night.
Try investing in a humidifier or air purifier to keep your humidity levels down on sweaty days, by sucking moisture out of the air.
Alternatively, try keeping a few air-purifying plants like peace lilies or rubber plants.
On top of this, make regular checks on your windows for cracks in the sealant which could enable the pollen to creep inside your home.
