If you are heading somewhere tropical this summer, or just want to protect yourself from bites in your own back garden, then which mosquito repellents can you trust? Greg Foot gets up close and personal with a box full of hungry mosquitoes to find out. Is it all about DEET or are there alternatives which are just as effective? What about citronella? And how well do bracelets, patches and candles perform? And if you do get bitten, what is the best treatment for a mosquito bite? Greg assesses the scientific evidence with Professor James Logan from the London School of Hygiene and Tropical Medicine and Dr Jane Wilcock, an indepedent researcher and GP.

Mosquito Repellents

This is one of your most-requested topics and as a keen runner myself I couldn’t wait to get into it. Barefoot shoes claim to encourage you to run in a more ‘natural’ way, landing on your mid or forefoot rather than on your heel. Some brands say they’ll increase your speed and reduce the likelihood of injury. But will they? Listener Sam runs marathons and wants to know if the science backs up the marketing hype. He also wonders whether the wider toebox in barefoot shoes really does allow for our toes to be separated out in a more natural way. It’s not just runners who got in touch either; Jon is a dog walker and is interested in wearing barefoot shoes on a more casual basis. Is there any benefit to that? And what about children? Listener Zoe already wears barefoot shoes herself but wants to know if they might be good for her son, too. In this episode I speak to experts to weigh up the evidence. Are barefoot shoes the best thing since sliced bread? Or just marketing BS? PRESENTER: Greg Foot PRODUCER: Simon Hoban

Barefoot Shoes

Owners clearing up after the UK's 11 million estimated pet dogs have a bewildering array of bags from which to choose. Some are labelled 'degradable', others are called 'biodegradable', 'compostable and biodegradable' or 'recycled.' So which ones are best for the environment? And what is the most environmentally friendly way of disposing of our dogs' doo? Greg Foot is on the case on behalf of listeners including Nicola Jones and Craig Hart who are perplexed by the claims being made on dog poo bags.

Dog Poo Bags

Which cycle helmets give you the best protection? I’m a big fan of cycling and so when listener Migue got in touch wanting to know what cycle helmet he should buy next, I was really keen to investigate. Migue wanted to know what factors make a cycle helmet the most effective when it comes to protecting your head: the shape, the material, the fit? He’s seen all sorts of neat tech, including collapsible helmets and ones that fit around your neck and act like airbags! To find out more I speak to an expert at one of the world’s leading helmet testing labs in Virginia, USA. And in researching this episode I also discovered there is a hotly-contested debate about whether cycle helmets should be the focus at all when it comes to safety. Some - including the organisation Cycling UK and the charity Sustrans - argue that introducing tougher rules around helmets would mean far more lives lost through physical inactivity than would be saved in protecting from collisions, which are rare. That’s a view shared by Dr Ian Walker from Swansea University, who also features in this episode.

During the pandemic, as people sought to protect themselves from Corona Virus, more and more products entered the market claiming to use Ultra Violet light to clean your belongings. These vary from UV wands and lamps, to phone boxes and UV baby bottle sterilisers. You may have seen them advertised online, claiming to kill 99% of viruses and bacteria. But do they deliver, and are they worth it, compared to more traditional methods of cleaning like alcohol wipes, or soap and water... That's what listeners Chris and Ben wanted to know. I'll be finding out by speaking to an expert in radiation safety Professor John O'Hagan at Loughborough University and Matt Knight, Product Testing Expert at the consumer group Which?

UV Sterilisers

If you’ve ever made the mistake of going for a hike wearing just jeans and a t-shirt you’ll know it can be a pretty sweaty, uncomfortable experience. But it doesn’t have to be that way! There are myriad products promising to keep you dry, warm and protected from whatever the weather can throw at you. Listener Julie is keen to know more about that after she went on an adventure holiday without the right kit, leaving her cold and miserable. She’s heard about fabrics that promise to ‘wick away’ the sweat and others that keep you warm in cold weather and cool when it’s hot. And what about the jackets that claim to stop rain getting in yet still be breathable enough to let vapour and sweat out. How does that work?! I’ll be finding out by speaking to an expert in textile technology and the Gear Editor from the UK’s best-selling walking magazine.

According to recycling charity Wrap, an estimated three billion nappies are thrown away every year in the UK. Concerns over plastic waste and a want to save money have been driving a rise in the popularity of reusable nappies but, as listener Amy asks, are they really better for the planet, and your pocket? Me and the team speak to Wendy Richards, also known as The Nappy Lady. She runs one of the biggest nappy advice and sales websites specialising in reusables. Crunching the numbers with her we look at the complete financial costs of both reusable and disposable nappies, even taking into consideration the extra washing costs needed to clean reusables. But what about the environmental impacts of reusable nappies. Are they really better than disposables when you factor in the energy and water used to clean them? That's what we ask Professor Rob Holdway from Brunel University and Giraffe Innovation. Giraffe Innovation recently completed a thorough study - commissioned by DEFRA, the government’s Department for Environment, Food and Rural Affairs - looking at exactly this.

What works to help with the symptoms of hay fever? The better weather’s here but for the millions who have hay fever that just means a runny nose and itchy, streaming eyes. And for some people it’s seriously debilitating – listener Richard got in touch because his wife can’t go out and play with the kids in the spring and summer months. In this episode I’m investigating the treatments that claim to help. I speak to an expert from Allergy UK to find out what works and whether - as listener Lisa wonders - the generic or own-brand versions work as well as the more expensive branded ones. And could a hay fever injection be the one-shot solution Richard’s wife is looking for? Also, you might have heard about the gut microbiome…but did you know there’s a nasal microbiome too?! I’m finding out about some new research which shows probiotics could play a role in treating hay fever.

Sales of alcohol-free beer in the UK have more than tripled in the past five years, and you'll find more types of no and low-alcohol beer on sale in your local supermarket. But what does 'alcohol-free' really mean? And are these drinks always better for your health? Various listeners got in touch with us about this one, so we enlisted the help of two experts to answer their questions. Laura Willoughby knows a lot about no/low alcohol beer as co-founder of Club Soda which says it exists "to help people drink more mindfully and live well”. Kerry Torrens is a registered nutritionist who has been working in the food and drink sector for two decades.

Low and No Alcohol Beer

Research suggests four in 10 of us do it and it can even get so bad it’s been blamed for the breakdown of relationships. Snoring can be a living nightmare for you and your partner. But what if there was something that works to give you – and the people around you – a more peaceful night’s sleep? Listener Neville got in touch with a recording taken by his wife of him snoring – and it’s pretty loud! He’s seen various solutions from throat sprays to nasal strips and even a chinstrap which literally keeps your mouth shut while you sleep. But do any of them actually work? Are they the best thing since Sliced Bread – or marketing BS? I speak to experts to find out including an Ear, Nose and Throat surgeon and a scientist who’s looked into the extreme end of snoring.

Is sourdough the best thing since Sliced Bread? It’s the last episode in the current series so I thought it was about time I investigated this! Listener Janet got in touch wanting to know whether sourdough really does live up to the hype. Is it better for our digestive health than other breads? Is it made with fewer additives? And do the cheaper sourdough loaves we can buy in the supermarket really cut it - or are they just ‘sourfaux’? To find out, I went to a baking school to make a sourdough loaf from scratch, learning about the process and ingredients that go to make the sort of sourdough you’d find at an artisan or traditional bakers - and might cost over five pounds. And I speak to one of the world’s leading nutritional experts on bread to find out which types we should eat for our health.

Mascara is a crucial element of many a make-up bag - but can mascaras really deliver on their promises of longer, fuller, or curlier lashes? Listener Kath got in touch to ask exactly that. She also wants to know if you pay more for mascara, do you get better results? How should we remove it - and what about waterproof products that are tough to take off? Are we potentially damaging our lashes? Greg Foot sets his sights on investigating by recruiting some regular mascara wearers to try out differently priced products, as well as speaking to a consultant dermatologist and cosmetic chemist to find out.

Do toothpastes promising to repair enamel and help with sensitive teeth really work? We've all been there - you go down the supermarket aisle to grab toothpaste and suddenly you’re faced with an ocean of the stuff, all promising to do different things.

Sleep is never more important than when you aren’t getting any. And there’s a large range of night time teas, herbal tablets and relaxing oils and sprays that promise to help you get some. But can they really deliver?

We spend a lot of time on them so it’s important to get the right mattress. But buying one can be confusing. Some use springs while others are made out of foam - or there’s a combination of both. Then there’s memory foam, with brands like Tempur claiming to make their mattresses out of ‘proprietary’ material. And can a good mattress help to alleviate back pain? These are the questions keeping listener Stephen up at night and he tasks presenter Greg Foot with finding out more. Greg speaks to experts in the mattress industry and a sleep specialist, looking at the scientific evidence to test whether the claims made by mattress manufacturers live up to the marketing hype.
