The government is warning that the NHS will be under even more pressure this weekend as temperatures soar, so looking after yourself in the sunshine is crucial.
But how much do you know about the science behind sunburn… and how to prevent it?
What is sunburn?
While we all know what sunburned skin looks like – red and sore – it might not be so clear what is happening underneath the skin.
“Essentially, it’s inflammation,” said Dr Rachel Abbott, a consultant dermatologist who specialises in skin cancer for the Cardiff and Vale University health board.
“It’s triggered by ultraviolet radiation, primarily UVB but also by UVA.”

Ultraviolet radiation is carcinogenic and when it is allowed to penetrate the skin, it triggers an inflammatory reaction, said Dr Abbott.
Histamines – chemicals produced by the body’s immune system – and prostaglandins – compounds that help the body deal with injuries and illness – are released as your body begins reacting to the damage.

Although the inflamed, red, itchy skin will fade, those carcinogens will do permanent damage to your DNA, according to Dr Abbott.
“The redness and pain can be managed symptomatically, but that DNA damage is permanent,” she said.
“We’ve all got DNA repair mechanisms in our bodies. But this is why we’re seeing such a massive increase in skin cancer, because [as we get older], the battle between the DNA damage and the skin cells becomes more than the immune system can cope with.”

Since the early 1990s, the number of skin cancer cases in Britain has more than doubled and last year, the number of cases was predicted to hit an all-time high of 20,800, according to Cancer Research UK.
The cancer charity partially attributed the rise in cases to older groups of people knowing “less about the dangers of tanning in their youth”, who “may have taken advantage of the cheap package holiday boom from the 1960s”.
This would lead to increased sun exposure and more damaged DNA, increasing the risk of skin cancer further down the line.
The ‘most effective’ protection (and it isn’t suncream)
There is currently no conclusive treatment to deal with the DNA damage caused by sunburn – although Dr Abbott said there is “exciting” work being done in that area.

Instead, the way to stop yourself from sustaining long-term damage is to protect yourself from UV rays.
“A lot of people associate temperature with the heat of the sun, whereas actually it’s the UV index that’s the critical thing. And that usually peaks around midday,” said Dr Abbott.

What is a heatwave?
Contrary to what some may think (or hope), suncream should be a last resort.
Shade “is the most effective thing”, she said, but if you have to be out in the sunshine, “obviously we recommend hats, clothing and then sunscreen”.
“It is a last resort for those areas that you can’t cover up with clothing and hats, and sunglasses.”
The cancer care charity Macmillan recommends a suncream with a sun protection factor (SPF) of 50, or at least 30, and to reapply it regularly.
“There is no such thing as a safe suntan,” advises the charity.
It also recommends using around six to eight teaspoons of suncream for an adult – one teaspoon for each limb, one for your chest, one for your back and one for your head and neck.
Donald Trump has threatened to sue the BBC for $1bn over edits the organisation made last year to one of his speeches.
The organisation has been engulfed in a crisis, forced to apologise on Monday after two of its most senior figures, including the director-general, resigned on Sunday night.
The defamation claim centres around a BBC Panorama documentary, which aired October 2024 and showed an edited speech made by Mr Trump before the attack on the US Capitol on 6 January 2021, in which he appeared to tell his supporters he was going to walk with them to the US Capitol and “fight like hell”.
In a letter dated 9 November, Florida-based lawyer Alejandro Brito set the BBC a deadline of 10pm UK time on Friday to respond, outlining three demands:
• Issue a “full and fair retraction” of the documentary, • Apologise immediately, • “Appropriately compensate” the US president.
He told the BBC it needed to “comply” or face being sued for $1bn.
A BBC spokesperson said: “We will review the letter and respond directly in due course.”
‘Error of judgement’
On Monday, BBC chairman Samir Shah, one of the most senior figures still standing, apologised for the “error of judgement” in editing the video.
In a letter to the Culture, Media and Sport Committee of MPs, Mr Shah said Mr Trump’s speech was edited in a way that gave “the impression of a direct call for violent action”.
“The BBC would like to apologise for that error of judgement,” he added.

BBC admits Trump documentary ‘mistake’
Director-general and head of BBC News resign
Concerns about the edited speech first came to light in a leaked memo from Michael Prescott, a former journalist and independent adviser to the BBC’s Editorial Guidelines and Standards Board.
As a result, BBC director-general Tim Davie and BBC News chief Deborah Turness announced their resignations on Sunday evening, saying in emails to staff that mistakes had been made.
Mr Davie will address an all-staff meeting on Tuesday. While on her way into the Broadcasting House on Monday morning, Ms Turness defended the corporation, rejecting accusations of institutional bias.

Downing St stands by BBC – but chancellor says ‘lessons to be learned’
A spokesperson for the prime minister told reporters on Monday that the BBC wasn’t corrupt or institutionally biased.
Instead, they said it had a “vital role” to play in the modern age, but needed to ensure it acted “to maintain trust and correct mistakes quickly when they occur”.
Chancellor Rachel Reeves also stood by the corporation, but said that “lessons do need to be learned”.
‘Nothing but an apology’
Veteran broadcaster and former BBC presenter Jonathan Dimbleby told Sky News, however, that the organisation owed the US president nothing more than an apology.

BBC ‘very likely to consider settling with Trump best thing to do’
Rachel Reeves has signalled she is going to break her manifesto tax pledges at the budget – and has given her strongest indication yet she will lift the two-child benefit cap.
The chancellor said the world has changed in the year since the last budget, when she reiterated Labour’s manifesto promise not to raise national insurance, VAT or income tax on “working people”.
“It would, of course, be possible to stick with the manifesto commitments, but that would require things like deep cuts in capital spending,” she told BBC 5Live.
“I have been very clear that we are looking at both taxes and spending,” she added.
The chancellor also gave her strongest indication yet she will lift the two-child benefit cap at the budget on 26 November, saying it is not right a child is “penalised because they are in a bigger family”.
Ms Reeves blamed poor productivity and growth over the last few years on the previous government “always taking the easy option to cut investment in rail and road projects, in energy projects and digital infrastructure”.

‘I’ll always do what’s right for UK’
“What I can promise now is I will always do what I think is right for our country, not the easy choice, but the thing that I think is necessary,” she added.
The chancellor blamed the UK’s lack of growth under her tenure on global conflicts, trade and tariffs over the past year.
In a dig at Donald Trump, who has imposed wide-ranging tariffs on countries around the world, she said: “The tariffs. I don’t think anyone could have foreseen when this government was elected last year that we were going to see these big increases in global tariffs and barriers to trade.
“And I have to be chancellor in the world as it is not necessarily the world as I would like it to be. But I have to respond to those challenges, and that’s the responsible thing to do.”

‘Shameful’ that 4.5m children in poverty
‘Children should not be penalised’
The government has, so far, resisted lifting the two-child benefit cap, which means a family can only claim child benefits for the first two children.
But, it is a contentious subject within Labour, with seven of its MPs suspended two weeks after the election for voting to scrap it, while others are aware it will cost £2.8bn to do so.
She said she saw Mr Brown at Remembrance Sunday, where they “had a good chat and we’ve emailed each other just today”, as she revealed they speak regularly.

Labour’s child benefit cap dilemma
Ms Reeves added Mr Brown and Sir Tony Blair were big heroes of hers because they did so much to lift children out of poverty – the reason she went into politics.
Pushed on whether she would lift the cap, she said: “I don’t think that it’s right that a child is penalised because they are in a bigger family, through no fault of their own. So we will take action on child poverty.”
The latest YouGov polling found 59% of the public are in favour of keeping the cap in place, and only 26% thought it should be abolished.
Shadow chancellor Sir Mel Stride said: “Rachel Reeves has borrowed, spent and taxed like there’s no tomorrow – and she’s coming back for more because she doesn’t have a plan or the strength to stand up to Labour’s backbenchers, who are now calling the shots.
“My message is clear: if Rachel Reeves reduces government spending – including the welfare bill, she doesn’t need to raise taxes again. “
After Tim Davie’s resignation announcement only a day ago, talk is turning to who could replace him and take on the highest-profile role in British broadcasting.
The BBC‘s director-general position is a crucial role, serving effectively as both the corporation’s chief executive and its editor-in-chief across television, radio and online.
Davie, who has worked for the BBC for 20 years and been in charge for the past five, is not stepping down immediately.
He said in his departure note to staff that he is “working through exact timings with the board to allow for an orderly transition to a successor over the coming months”.
It is still early days, but here are some of the names being discussed as contenders for the role.
Charlotte Moore

Chief executive of Left Bank Pictures, a British independent TV and film production company owned by Sony, Charlotte Moore was chief content officer at the BBC for five years before leaving in the summer.

She was among those shortlisted when Davie got the job in 2020 and is known as the mastermind behind the commissioning of The Great British Bake Off.
In March 2023, she was awarded the Royal Television Society Judges Award in recognition of her leadership “through one of the most momentous years in [the BBC’s] history and having done so with an exceptional combination of steadfast level-headedness, confidence and creative flair”.
“The BBC is an extraordinary place to work,” she said in a statement when her move to Left Bank was announced.
“There’s nowhere quite like it that backs risk-taking, innovation and homegrown creativity with such commitment.”
James Harding

A former editor of the Times and director of BBC News, James Harding is the co-founder and editor of slow news venture Tortoise Media, which bought The Observer newspaper in December 2024.
Harding called for the BBC to be “put beyond the reach of politicians” in an interview with Sky News before giving the James MacTaggart Memorial Lecture at the Edinburgh TV Festival in the summer.
Establishing the independence of the BBC is critical “if we want to build confidence in shared facts and respect for the truth”, he said.
Jay Hunt

Jay Hunt is Apple TV+’s creative director for Europe and was appointed chair of the British Film Institute in 2024.
She has previously worked as chief creative officer for Channel 4, director of programmes at Channel 5 and controller of BBC One.
Channel 4 was named Channel of the Year at the Edinburgh International Television Festival in 2014 and 2016 under her leadership, and she was known for buying the rights to The Great British Bake Off from the BBC.
At Apple, she has overseen commissioning for award-winning shows such as Bad Sisters and Slow Horses.
Alex Mahon

After almost eight years as chief executive of Channel 4 – the first woman in the broadcaster’s history to take the helm – Alex Mahon left the role earlier this year to lead live entertainment group Superstruct Entertainment.
Superstruct owns and operates more than 80 music festivals across 10 countries in Europe and Australia, including Boardmasters in Cornwall and Mighty Hoopla.
Mahon’s move allowed her to earn a more lucrative remuneration package than the one on offer to her at Channel 4, Sky News City editor Mark Kleinman reported at the time.
Dawn Airey, Channel 4 interim chair, described her as a “great figure in British television” and said she had been “one of the most impactful CEOs” since the founding of Channel 4 in 1982.
She was the recipient of Variety’s 2020 International Achievement in Television Award and has been honoured with an International Royal Industrial Fellowship.
Dame Carolyn McCall

Dame Carolyn McCall has led ITV since she joined the channel in 2018, having served as chief executive of easyJet for seven years and chief executive of the Guardian Media Group for four years.
She was made a dame in 2016 for services to the aviation industry and an OBE before that in 2008 for services to women in business.
She has led ITV plc’s “significant transformation in the competitive digital media landscape since joining in 2018, successfully evolving it from a linear organisation to a strong linear and digital media, entertainment, and global production business”, her biography for the broadcaster states.
Another name that has been suggested by a few commentators is Sky News’s Sir Trevor Phillips, who presents Sunday Morning With Trevor Phillips each weekend.
A businessman and journalist, Phillips has won Royal Television Society journalism awards three times. He is also a Times columnist and was shortlisted for Comment Writer of the Year in 2020.
Phillips, who was knighted in 2022 for services to equality and human rights, was previously head of current affairs for London Weekend TV (where he worked alongside BBC chair Samir Shah), chair of the London Assembly, chair of the Commission for Racial Equality, chair of the Equality and Human Rights Commission and president of the John Lewis Partnership Council.
His name has been mentioned as a possible contender on political website Guido Fawkes, as well as by Rod Liddle on Times Radio and journalist Stephen Pollard in a column for The Spectator, headlined: “Is this the man who can save the BBC?”
Senior BBC staff
Could the BBC look internally?
One name that has been mentioned is Jonathan Munro, who, since joining the BBC in 2014, has led news coverage “through every major story over the last decade”, his biography for the broadcaster states, from Brexit to UK general elections, and the death of the Queen to the wars in Ukraine and Gaza.
He became global director of BBC News in September 2024, and is also director of the BBC World Service and deputy chief executive of BBC News and Current Affairs.
There is also Kate Phillips, who replaced Moore as chief content officer, the senior executive responsible for all the BBC’s network TV and radio output, in the summer.
She has only been in the role for a few months, having previously held the position of director of unscripted content. During the pandemic, she was acting controller of BBC One.
In other circumstances, BBC News chief executive Deborah Turness perhaps could have been a possible candidate to replace Davie, but she announced her resignation alongside his on Sunday night.
