Extreme heat is becoming more common around the world. From Europe to India, record-breaking heatwaves are affecting millions of people - but what is all that heat actually doing to our bodies?

Brain fog, poor sleep, heat exhaustion and heatstroke are just some of the ways extreme heat can affect our health. So when does hot weather become dangerous, and how can you stay safe during a heatwave?

BBC Health Editor and doctor Michelle Roberts explains how the body keeps itself cool, why extreme heat can become life-threatening, and who is most at risk. We also hear from some of you about how you're coping with increasingly extreme temperatures where you live.

West Africa has been struggling with heavy rains. Ghana, Nigeria, Ivory Coast and other countries across the region have had severe flooding - you might have seen videos online. Deep water, filled gutters and lots of people trying to get to safety.

People have sadly died in the floods - at least 59 people in Ivory Coast and 13 people in Ghana. And more heavy rains are expected.

We hear from some of you in Ivory Coast, Ghana and Lagos for how you’ve been affected. Makuochi Okafor, our West Africa reporter, explains what’s been happening in the region.

Plus, Sophia Herod, from BBC Weather, takes us through how the weather works in this part of the world and how much climate change is playing a role in the rains.

Are those wedding bells we’re hearing? If the rumours are true, pop star Taylor Swift could get married this Independence Day weekend to NFL star Travis Kelce…in Madison Square Garden arena in the middle of New York City.

Not to sound like a gym bro…but the science is clear: more of us should start lifting. Strength training is when you lift weights or use your own body weight to build muscle — and it’s not just about toning up or getting ripped. A new study found it can actually help you live longer. So why is it so good for your health - and how can you start doing more of it?

Health correspondent Melissa Hogenboom joins us to unpack the latest studies on strength training and why we’re seeing a rise in its popularity. Personal trainer and nutritionist Luke Hanna explains the science behind the long-term health benefits of lifting weights. And we hear from some of you about why you’re getting into weightlifting.

The 2026 Fifa Men's World Cup has the highest proportion ever of players representing countries they were not born in - almost a quarter of all the participating players. Several squads, including those from DR Congo, Morocco and Bosnia & Herzegovina, have a team made up mostly of foreign-born players. Of the 26 players who represented Curaçao, only one was born on the Caribbean island.

Fernando Duarte, a reporter with the BBC World Service, explains why more World Cup footballers aren’t playing for their birth nations. He also highlights how Morocco, the only African team ever to reach the semi-finals of a World Cup, has successfully recruited players from its diaspora.

We also hear from football fans around the world about the foreign-born players representing Cape Verde, Curaçao, Morocco and Bosnia & Herzegovina.

When you think of fertility, you might automatically think of women’s fertility. But there are men online doing something called ‘fertilitymaxxing’ - it’s all about young men trying a bunch of unproven hacks in hopes of improving their sperm health.

Content with these hacks are often pushed by male wellness and manosphere influencers online - but is this really about raising more awareness of male fertility (which is an under-researched issue)? Or is it about other anxieties Gen Z men might have about their health - and masculinity more generally?

Jacqui Wakefield is our Global Health Correspondent and has been speaking to men, like Simon in Miami, who have been doing things like icing his testicles in a bid to boost sperm count. And also Professor Channa Jayasena, a reproductive endocrinologist and Imperial College, explains that some medicines these influencers are recommending can be very dangerous.

After a devastating double earthquake in Venezuela, tens of thousands of people are still believed to be missing, with many trapped under rubble. Nearly 1,500 people have been confirmed dead and the death toll is expected to rise. Aid agencies say the first 72 hours after a disaster are the most critical to finding people alive. But there is a lack of heavy machinery and specialised equipment needed to rescue people. Much of the emergency response is being carried out by volunteers and international aid workers from Turkey, the UK and France. BBC’s Global Affairs reporter Mimi Swaby gives us the latest update on the situation.

Against all odds, several videos online show miraculous stories of survival, like young infants and children being lifted from the rubble. Bill Murphy, a professor of engineering geology at the University of Leeds in the UK, tells us what increases the chances of survival in awful conditions like these.
