How to sleep: Shower before bed if you have allergies or hay fever

Allergy UK states: “Grass pollen is the most common allergen (May to July), but tree (February to June) and weed (June to September) pollens can also cause the allergic reaction we know as hay fever.

“In perennial allergic rhinitis the symptoms continue all year round and usually relate to indoor allergens, such as house dust mites, pets, including birds, or moulds.”

If your sleep problems are not related to allergies, the good news is that for most, sleep problems tend to sort themselves out within about a month, according to the NHS.

The health body says: “Most people experience problems with sleep in their life. In fact, it’s thought that a third of Brits will have episodes of insomnia at some point.”
