This is how long you should keep your reusable water bottle for
Do you know exactly when to get rid of your reusable water bottle? No, they won't stay perfect forever.
It seems like everyone you encounter has a form of reusable drinkware these days, whether it be a Chilly's bottle, a Hydro Flask, or a Stanley cup – some own more than one.
In fact, in 2015, just 20% of people in the UK owned a reusable water bottle, with figures from Refill estimated to have risen to 60% in 2023.
Basically, it's a booming business, with the European refillable bottle market estimated to rise 40% on £1.5billion by 2028.
So, while reusable bottles aren't disappearing anytime soon, it's important to know how to take care of them if you have one, especially when your health – and life – is at risk.
A Taiwanese man ended up with lead poisoning from using a metal bottle for too long. Ultimately, he developed pneumonia, a serious lung condition, and later died.
As reported by local media, the unnamed individual had been enduring health problems for a year before blood tests confirmed the lead poisoning. The high levels of toxins in his blood prompted an investigation, with medics informed that he had used the same thermos every day for 10 years.
Upon inspecting it, they saw the lining beginning to corrode, plus signs of rust, perhaps caused by the acidic fizzy drinks he often put inside it.
While it's unknown exactly when the bottle's wear and tear might have started to affect him, it's believed that, by the time he sought help, it was already too late.
As such, experts are issuing warnings to those with reusable bottles to prevent tragedy.
Metal water bottles are the most common, which is great because they are durable, hygienic, and reduce plastic waste.
They also have a long lifespan with no hard expiration date. However, if you start to notice cracks, dents, or scratches, particularly in or around the seal, it's probably time to replace it.
It is estimated that a stainless steel bottle can last up to 12 years, thanks to its sturdiness and ability to withstand direct sunlight.
These warnings include ensuring that your drinking bottles are made of high-quality, food-grade materials, such as 304 stainless steel.
It is also not advised to store acidic or carbonated beverages in them, including fizzy drinks and fruit juice.
It starts to smell
It becomes cracked, dented, or scratched
In or around the lid or seal is damaged or discoloured in any way
Janilyn Hutchings, a certified professional in food safety at StateFoodSafety, explained to Delish last year: 'This might seem obvious, but reusable water bottles don't last forever. Over time, water, and especially more acidic drinks like lemonade, slowly break down the material your bottle is made of.'
She added: 'If you are cleaning or sanitising your water bottle using methods that are not approved for that material or water bottle that you're working with, that means that you can accidentally be doing damage to the structural integrity of that bottle.'
So, while a bottle can last for several years if properly cared for, experts suggest discarding it after two to three years if you use it constantly.
In the meantime, you must clean your bottles regularly – and here's how.
Simply rinsing your bottle with cold water after use isn't enough to eradicate the build-up of bacteria, which then comes back into contact with your mouth.
It's recommended to clean your reusable bottle with hot water (over 60 degrees Celsius) and swirl washing up liquid around it.
Leave the bottle for 10 minutes to soak before rinsing thoroughly with hot water again. This is your best chance of killing off all pathogens. More Trending
Since bacteria thrive in warm, moist environments, you should allow your bottle to air dry completely before using it.
Finally, wash your hands before touching your squeaky clean bottle again.
Repeat this cleaning process at most after each use. At the very least, do it a few times per week, especially if you're using the bottle daily.

ADHD waiting list led to rise in unregulated private providers
The ADHD taskforce, commissioned by NHS England with the support of the Government, has published an interim report saying the system for diagnosing and managing ADHD needs to be overhauled. At the moment, ADHD assessment and treatment in England is provided by highly specialised doctors in secondary care. But the report warned: 'Inability to access NHS services has led to a significant growth in the use of private providers that are not regulated, resulting in two-tier access to services, diagnosis and treatment; one for those who can pay and another for those who cannot. 'This drives health inequalities and links to disproportionate impacts and outcomes in the education and justice systems, employment and health.' Experts behind the study said waiting times for NHS ADHD services 'have escalated and are unacceptably long' and demand on services is 'very likely' to continue to rise. The taskforce concluded that ADHD is not solely the remit of the NHS and other health providers, with schools being vital for identifying and meeting needs at an early stage. And while a clinical diagnosis of ADHD via the NHS is required if a person needs medication, early support can still be provided to others. The report said: 'We need timely recognition and early support of suspected ADHD and neurodivergence across all settings. 'This is especially important in schools and the early years, to prevent adverse impacts and costly outcomes in the future. This should be needs-led and not require a clinical diagnosis.' The report also suggested there is no evidence of over-diagnosis of ADHD in the UK. It argued: 'England and the rest of the UK have much lower service recognition and treatment rates of ADHD diagnosis compared with other European countries. 'Recent data show a very high level of under-recognition and under-treatment of strictly diagnosed ADHD, with significant inequalities in access to care.' The report also addressed concerns about potential 'over-medicalisation and over-diagnosis', including worries that people are self-diagnosing ADHD based on information from social media. However, the report, said that 'currently there is no good evidence on what percentage of those waiting to see a clinician have self-diagnosed ADHD using social media and eventually meet or do not meet ADHD diagnostic criteria after a high-quality assessment. 'We only know currently that in England, recognised rates of ADHD are lower than the expected prevalence of ADHD.' Currently, the estimated economic costs of not treating ADHD are around £17 billion to the UK economy, the report went on. This includes through lower tax contributions, people needing state benefits and more likely to be not in education, employment or training, or who are long-term unemployed. 'Many of these costs are avoidable, as with appropriate, early support, people with ADHD can thrive,' it said. Professor Anita Thapar, chair of the ADHD Taskforce, said: 'The recommendations put forward by the taskforce will require action across Government and cross-sector organisations to make the necessary changes to improve the lives of people with ADHD. 'We need to get this right, to make sure people get early diagnosis and support, not just in the NHS but across society.' Dr Adrian James, NHS England's medical director for mental health and neurodiversity, said: 'We know that too many people with ADHD have been waiting for too long for support, which is why we launched the taskforce last year to help respond to the significant growth in the need for care. 'It is clear that much more needs to be done to improve ADHD assessment and care in England and ensure people can get a timely diagnosis, and we welcome the findings from the interim report, and look forward to its final conclusions later this year.' A Department of Health and Social Care spokesperson said: 'Lord Darzi's report into the state of the NHS laid out how severe the delays have become for people waiting for an attention deficit hyperactivity disorder diagnosis. 'We welcome the publication of the ADHD Taskforce's interim report, which provides valuable insights into the challenges affecting those with ADHD, including access to services and support.' The NHS has launched publicly-available data collection on ADHD referrals and waiting times to help local teams better understand how they are performing. By March 2026, the Government also aims for six in 10 pupils to have access to a mental health support team in school.

Central Park's gorgeous Conservatory Garden has reopened after years of construction
For the past three years, tall fences closed off one of the most beautiful parts of Central Park. Now, after three long years of extensive restoration, the spectacular Conservatory Garden is open once again and is in full bloom. The Conservatory Garden is a six-acre formal garden located in the northeastern quadrant of the park known for its peaceful design and historic charm. The garden underwent at $25 million glow-up, the most significant investment in the space since it was built in 1937, the Central Park Conservancy announced this week. Go see it along Fifth Avenue between 104th and 106th Streets in Central Park. The garden's three distinct styles—French, Italian, and English—have attracted many weddings and photoshoots over the years. It's also a beloved spot for New Yorkers looking for a moment of tranquility in the city. Visiting feels like a taking stroll through a European garden without having to buy a plane ticket. In the springtime, peonies and lilacs surge into bloom at the Conservatory Garden. In the fall, look for a bevy of mums among the garden's neatly trimmed hedges. While many of the garden's horticultural elements were addressed in 1983, this restoration focused on the comprehensive renewal of its historic hardscape, such as restoring bluestone pavers, updating stormwater draining, modernizing fountains, installing ramps and realigning paths. This type of restoration work hadn't been done at the garden in nearly 90 years. In addition, staff also replanted the Italian Garden's iconic crabapple allées with disease-resistant trees and repaired the steel pergola. This is a big year for upgrades to Central Park. The long-awaited Davis Center at Harlem Meer is now open. And the historic Delacorte Theater (where Shakespeare in the Park is staged every summer) will soon reopen after reconstruction.
