Though the arrival of spring is most welcome, it can also be a time of sneezing and sniffling if you suffer the troublesome but very common symptoms of hay fever. Of course we associate the condition with pollen-spreading plants, but it turns out the composition of our gut bacteria – which influences our immune system – can also play a role in hay fever risk.

People with a less diverse range of gut bacteria appear to be more likely to get symptoms. And understanding this link could point us to potential alternative treatments for hay fever. In fact, there’s already some research showing certain probiotics and prebiotics could help with symptoms.

Speaking of irritating airborne particles, we’re all exposed to air pollution when we’re cooking, and not only from gas burners. Two experts explain the health risks and how to protect yourself.

Plus we look at the factors that determine job quality (hint: it’s not just about pay). Learn how improving job quality could be a way to fix the significant problems plaguing the British labour market.
