For some women, the two-week luteal phase of their menstrual cycle can be extremely disruptive and life altering. PMDD or Premenstrual Dysphoric Disorder is mental health disorder directly linked to regular hormonal fluctuations that take place during a cycle. People living with PMDD can experience anger, anxiety, severe depression, and even suicidal thoughts which then stops shortly after menstruation begins. Two women, Shariya in the US and Janna in Germany tell us how PMDD has impacted them.

There’s very little scientific research about why PMDD happens and the signs or symptoms can be missed by doctors. We hear from BBC Health Reporter Ruth Clegg, who’s been reporting on how social media has shifted perceptions of the disorder, and led to changes around how doctors screen for symptoms.

A heatwave across Western Europe has left tens of millions of people coping with record temperatures. France endured its hottest day since records began, with temperatures reaching 44.3C in Pissos, and it’s estimated that nearly 100 million people will endure temperatures of over 35 degrees Celsius on Wednesday. Temperatures can feel particularly extreme in cities, where buildings trap heat and where there’s often a lack of green spaces.

In today’s episode, BBC weather presenter Sarah Keith-Lucas explains why we’re seeing more heatwaves. We also hear from people around the world about what it’s like where they live. And several BBC reporters — Davide Ghiglione in Rome, Pierre-Antoine Denis in Nice, Makuochi Okafor in Lagos and our Chelsea Coates and William Lee Adams in London — explain how people in various cities are addressing rising temperatures.

For decades, mangrove forests were disappearing at an alarming rate. Now, new satellite data reveals a hopeful shift. After years of decline, these vital coastal ecosystems are making a comeback.

In this episode, BBC environment correspondent Matt McGrath explains what mangrove forests are, why they suffered such significant losses from the 1980s through the 2010s and how advances in technology are allowing scientists to track their recovery from space. We also examine why mangroves are one of nature’s most powerful tools for protecting coastlines, storing carbon and helping communities adapt to climate change.
