6 hot weather health mistakes a doctor wants you to stop making
But with parts of the UK set to enjoy a mini heatwave this week, with some regions reaching a toasty 29 degrees, it's never been more important to stay sun safe.
From applying your SPF haphazardly to going too hard with your training, there's a plethora of hot weather mistakes Brits commonly make in the summer months.
Keen to avoid them? Here's what a doctor wants you to know ahead of this weekend's mini heatwave.
When you've got plans to throw a towel down in the park, it's tempting to rush out of the house and apply your sunscreen once you've snagged a prime picnic spot.
But Doctify-rated dermatologist Dr Sweta Rai warns against this strategy. "The most common heatwave mistake I see people making is putting sunscreen on once they're out in the sun," she notes.
Sunburn can occur in less than 15 minutes when you're exposed to the sun's rays, but as the tell-tale red inflammation can take hours to develop, many people don't realise their skin is at risk.
"I always recommend applying suncream an hour before you leave the house and carrying a bottle in your bag so you can reapply regularly," Rai adds.
Speaking of re-application, Rai says that hot weather perspiration can quickly wash away a protective layer of suncream.
"If you can feel sweat forming in areas like the elbows and back, wipe the moisture away with a tissue or towel, and reapply your suncream immediately," she advises.
The same goes if you're planning to swim. "If you're in water, be mindful of the fact that your suncream will only last for around 40 minutes," she adds. "You could set a timer on your phone if you're heading into the pool for a swim, and reapply your cream once the alarm goes off."
If you're currently in the midst of a marathon training plan, you don't need to ditch your training sessions entirely. However, it's important to time them correctly.
"You want to avoid doing outdoor exercise between 11 to 3pm when the sun is at its hottest, and the UV is at its highest," stresses Rai. Not only will this keep you safe from a potentially nasty sunburn, but exercising in the blistering sun can increase your risk of heat exhaustion too.
"Most smart watches and phones have a feature that records the UV index," Rai continues. "If the meter is showing a moderate or high recording, you might want to consider taking your workout indoors, or at the very least, liberally applying a good layer of suncream."
When it comes to SPF, there are some seriously exposed spots on our bodies that we often tend to forget, like our ears, eyelids and hair parting.
"Many of these delicate areas project from the body, which means they're getting a lot of sun exposure when we're out and about," warns Rai."During the summer, I see lots of patients coming in with painful red burns on the tips of their ears and the backs of their necks, so it's always important to pay special attention to these areas when you're applying your suncream."
Regardless of whether you're planning to hit the gym this weekend, stocking the fridge with a few sports drinks can help you to avoid dehydration when the mercury rises - which can cause headaches and nausea.
These 'isotonic' drinks contain similar concentrations of salt and sugar as in the human body, helping you to replenish the electrolytes you lose in your sweat.
"If you're you're outdoors in the heat and sweating a lot, then rehydrating with something more than just water might be helpful," adds Rai.
Finally, it's a myth that you should be reaching for your lightest and breeziest clothing on hot days.
"Wearing loose clothing is always a good idea for air flow, but when it comes to fabrics, its best to opt for those that are a slightly thicker, as these don't let the UV light filter through," explains Rai.
"Denim is a surprisingly good fabric to wear in the sun as it has a thicker weave and darker colour which provides more protection from UV."
Rai's bonus heatwave tip? "If you hold your clothing up against the window and can see tiny holes with light filtering through the fabric, it's probably not going to give you decent protection from sun damage," she notes.
"If you want to be extra careful, some companies now produce UPF clothing that's specially designed to block out UV light.
"This can be especially useful if you know you're going to be spending long periods of time in the sun and don't want to put yourself at higher risk of summer health issues."

Croydon man with mental health difficulties left homeless with no help
A vulnerable man was left sleeping in the rain after Croydon Council repeatedly failed to help him, despite his pleas for support. The Local Government and Social Care Ombudsman found that the man, who has mental health difficulties, first asked the council for help in July 2023 after becoming homeless. The council misplaced his records, and in the following months his condition worsened and he lost contact with his family. He eventually reached out to relatives again, and with help from one of his sisters (Sister A), made a new homelessness application. In October, another sister (sister B) discovered him sleeping rough outside her home during heavy rain. She took him in, but her own serious health problems meant this could only be temporary as living with him was also difficult due to his mental health needs. READ MORE: The council closed his case in November without informing sister B who had been speaking to them on his behalf. Officials said they had tried to contact the man for an interview, but she told the Ombudsman she had waited by the phone and made three calls to the council that day. The relationship between the man and Sister B later broke down, meaning that the man had to look elsewhere for somewhere to live. After sister A asked the council for help again, it eventually placed him in interim accommodation in March 2024. It accepted a full housing duty six months later. Later that month, the council issued the man a Personalised Housing Plan that listed actions for him to complete, such as providing his partner's passport and proof of income. The plan also stated that the 'applicant [was] to view accommodation sent to her' and that he should 'inform the council after the child has been born.' However, the man was the sole applicant, not pregnant, and had already been placed in temporary accommodation at the time. The Ombudsman said this showed the council had failed to properly understand the case. The council apologised to the resident, acknowledging delays in handling his case and poor communication during a period of major reorganisation in 2023. It said the resident is now in accommodation and receiving ongoing support. A spokesperson added that the housing service had been affected by years of underinvestment and underperformance and is now responding to a 50 per cent rise in homelessness support requests, with over 4,800 applications and more than 3,600 households in temporary accommodation. The council has since paid the victim £2,000 for the injustice caused. It will also reimburse £6,400 for bed and breakfast costs he covered between May and October 2023. His sisters will receive £700 in total for the distress they experienced. Croydon Council has committed to reviewing the case, reminding staff of their legal duties, and improving how it communicates with homeless residents and their families. The Ombudsman has upheld nine homelessness complaints against the council in the past two years. The Ombudsman, Ms Amerdeep Somal, said: 'This is a clear case of the dire things that can happen when councils are not on top of their homelessness services and allow vulnerable people to fall through the cracks. 'The siblings have told me this has caused substantial damage to their relationships. 'The man had a mental health crisis during the time he was missing and has since been withdrawn and isolated, and the sisters are still working to rebuild his trust. 'Sadly this is not an isolated case in the borough. In the past two years we have investigated eight other homelessness cases and upheld every one. 'I am pleased the council has accepted our findings and recommendations, I urge the council to take a firm grasp of its homelessness service to ensure other vulnerable residents are not treated in the same way as this man. 'The council has been subject to statutory government intervention since 2023. 'This intervention is currently under review so I will be sharing a copy of this report with the Minister for Local Government and English Devolution.' A Croydon Council spokesperson said: "We sincerely apologise to our resident and regret that he did not receive the support needed when he approached our service. This happened during a period in 2023 when the organisation was undergoing a major reorganisation. 'We accept that there were delays in handling his case and communications with him and his family should have been better. The resident has since been placed in accommodation and continues to be supported." 'Croydon is responding to a London-wide increased demand for homelessness support and saw a 50% increase in requests for homelessness support in 2024/5 and dealt with over 4,800 applications. More than 3,600 households are living in temporary accommodation in the borough. 'In 2023, Croydon's housing service was going through significant reorganisation after years of under investment in training and staff development and under performance of the service – which contributed to delays in case handling. 'These changes were made as part of major transformation of our service, with a renewed focus on prevention of homelessness. 'We introduced a new operating model which delivers both a face-to-face and telephone service to those seeking advice; appointment service to improve assessment outcomes; and placed a greater emphasis on tailoring our support for vulnerable residents with complex needs. 'We have increased staffing to ensure that personalised Housing Plans (PHPs) are issued accurately and on time. Staff have also had training to improve communication with residents, especially when a decision is made or a case is closed. 'There is more work to be done as part of this continued improvement of our housing services, whilst we respond to this London-wide issue.'

France supports Belgium's push to block US destruction of contraceptives
France has confirmed it is monitoring a US plan to incinerate millions of dollars worth of unused contraceptives in Europe – a move aid groups say is ideologically driven and medically wasteful. The contraceptives – including intrauterine devices (IUDs), implants and pills – were bought under public health programmes run by the US Agency for International Development (USAID). Since January, the supplies have been sitting in a warehouse in Geel, Belgium, after the Trump administration froze and then cancelled funding for reproductive health projects. The products, which were meant for use in low- and middle-income countries, were being stored as part of USAID's supply chain, managed by its logistics contractor Chemonics. Several media outlets have reported that the material may soon be transferred and incinerated in France, though no final decision has been confirmed. A diplomatic source told RFI that France 'firmly supports the Belgian authorities' desire to find a solution to avoid the destruction of the contraceptives' and is 'following the situation closely'. The source added that France had 'no information about any transfers that have taken place'. A US State Department spokesperson told the French news agency AFP that a preliminary decision had been made to destroy certain "abortifacient contraceptives" from USAID contracts, adding that no HIV medication or condoms would be affected. The destruction is expected to cost $167,000. The stock is valued at $9.7 million. French left urges Macron not to be complicit in US plan to bin contraceptives Redistribution offers rejected Several global organisations say they offered to collect and redistribute the supplies free of charge, but were turned down by US authorities. The International Planned Parenthood Federation (IPPF) said it proposed to recover the products in Brussels, transport them to its Dutch warehouse for repackaging, and then send them to countries in need. MSI Reproductive Choices, a UK-based group, told RFI it had offered to cover all the costs involved, including rebranding. 'We would have removed the stars from the USAID logo. It would have cost the US taxpayer nothing, nor the government,' said Sarah Shaw, MSI's advocacy director. 'We were told the US government would only sell the supplies at their purchase price. This is a situation we have never seen before.' Shaw estimated the stock would have covered Senegal's contraception needs for three years. The UN's sexual and reproductive health agency, UNFPA, also offered to buy the contraceptives but was turned down. 'This suggests the problem is not legal, but ideological,' Shaw said. 'It is a clear refusal to allow these contraceptives to be given to women in need. This US administration simply does not recognise their right to contraception.' The US State Department has described the items as 'abortifacient' – a term commonly used by anti-abortion activists to describe IUDs and other hormonal contraceptives. Since January, the Trump administration has banned any US funding to NGOs that support or promote access to abortion, even indirectly. What's stopping more men in France from getting vasectomies? French firm denies involvement Media reports have identified Veolia, a French waste management firm, as a possible contractor for the incineration. But the company told RFI it only has a framework agreement with Chemonics to handle expired products. 'The stock mentioned in Belgium is not part of this agreement,' Veolia's press office said. 'We are not responsible for its management.' Activist Danièle Gaudry, from the coalition Abortion in Europe – Women Decide, told RFI the timing of any transfer from Belgium to France remains unknown. 'We still don't know the date it will happen, and we're still trying to identify the company,' she said. France's parliament approves free contraception to be extended to women up to the age of 25 Lawmakers urge action On Saturday, French Greens leader Marine Tondelier and a group of female MPs urged President Emmanuel Macron to intervene, calling the plan 'an affront to the fundamental principles of solidarity, public health and sexual and reproductive rights that France is committed to defending'. They asked him not to become 'complicit, even indirectly, in retrograde policies' and to support NGOs ready to redistribute the contraceptives. Sarah Durocher, president of the French Family Planning association, said France had a responsibility to act. 'A government that proudly enshrines the right to abortion in its constitution must also defend access to contraception beyond its borders,' she said, in a statement issued by IPPF. The Elysée has yet to comment on the case.
