How Sweet Is Your Love?

Can changes in the weather have an impact on our mental health? We go to Bangladesh in South Asia, a country on the front line of the impacts of climate change, where researchers have been exploring connections between incremental changes in heat and humidity, along with bigger impacts like flooding, and the levels of anxiety and depression in the population. They say their study has stark implications, not just for Bangladesh, but for many other countries too. Dr Belinda Fenty joins us bringing in some coffees in the studio. But can presenter Smitha Mundasad spot which cup has the caffeine? Dr Fenty talks us through what coffee actually does to the body and ponders other questions like how much is too much and why might you crash after a coffee high.

She also take us through how to spot fake medicines and we take a look at an intriguing study on whether being married is good for your health. Presenter: Smitha Mundasad Producer: Gerry Holt
