Is it ok to drink warm bottled water? Expert issues warning
However, a warning has been issued over the risks of drinking warm bottled water. Leaving a bottle of water in the sun can "pose potential risks", an expert has warned. Here is all you need to know. Is it ok to drink warm bottled water? Ann Garry is a qualified nutritionist and the director of nutrition training and chief executive of Health Coaches Academy. She said that while warm bottled water on its own is not a problem, plastic bottles being left exposed to sunlight can cause issues. She said: "While warm bottled water isn't inherently dangerous, plastic bottled water left in warm conditions for a long time, particularly direct sunlight, can pose potential risks. "The primary concern is chemical leaching, where heat can cause plastic bottles to release small amounts of chemicals into the water. "Polyethylene terephthalate (PET), the most common plastic used in UK bottled water containers, can potentially migrate into the water when exposed to high temperatures." The expert also explained other risks associated with drinking bottled water that's been heated over a long period of time. Drinking warm bottled water could cause health problems (Image: Getty Images) Ann said: 'Other than PET, many plastic water bottles, especially older ones, contain a chemical called BPA (Bisphenol A), which can leach into the water when exposed to heat. "BPA has been linked to various health problems, including hormonal imbalances, developmental issues in children, and increased risk of certain cancers. "Even BPA-free bottles can release other chemicals that might be harmful. "Plastic bottles can also contain phthalates, chemicals used to make plastic flexible. Heat can cause phthalates to leach into the water, potentially disrupting the body's endocrine system.' Warm temperatures can also lead to bacterial growth, which can lead to illness, or affect the taste and odour of bottled water, she said. Plastic bottles can pose potential risks (Image: Getty Images) Ann added: 'To reduce these risks, it's best to avoid storing bottled water in places that are exposed to heat, such as a car on a hot day, and to choose alternatives like stainless steel or glass containers when possible. "If you're concerned about chemicals leaching from plastic, opt for BPA-free bottles or consider switching to reusable, eco-friendly options.' "Staying hydrated is far more important, though if you are feeling overheated, it's recommended to have a colder beverage, if you have the choice." How much water should I drink per day? The expert said: "Though there's no universal guideline to suit everyone, a good general recommendation is that the average adult should drink around 1.5 to 2 litres of water per day. "However, your individual needs can vary depending on your body size, activity levels, diet, if you're diabetic, and the climate you're in.' Ann also said that we can obtain some of our daily water intake from food such as fruits and vegetables, which have a "high water content". She also warned that while many drinks do contribute to fluid intake, "not all are equally hydrating". She said: "Water should always be your primary source of hydration, but herbal teas, diluted squash or cordial, and even your regular cup of breakfast tea can also count towards your daily intake. 'That said, it's a good idea to limit drinks high in sugar, caffeine, or artificial sweeteners, as they can have other beneficial effects on your overall health. 'For example, caffeine can have a mild diuretic effect in some people (promotes release of water), and sugary drinks can disrupt blood sugar balance. "In isolation, these types of drinks are best enjoyed in moderation and shouldn't replace your basic water intake.' Can you drink too much water? How much is too much Experts at DASH Water teamed up with renowned chef and nutrition, health and wellness coach Lisa Marley to answer the question. Telling Newsquest previously, Lisa said: "Yes, you can drink too much water in a day, which can lead to water intoxication or hyponatremia. "This happens when excessive water intake dilutes sodium levels in the blood, causing cells to swell." In severe cases, drinking too much water can lead to headaches, confusion, seizures or even death. Tips on staying hydrated this summer Ann suggested some top tips on drinking more water and staying hydrated this summer, these are: Begin your day with water - start with water first thing in the morning, cold or warm, sipping rather than drinking a whole pint in one go helps better hydration. Carry a water bottle everywhere - Having a reusable bottle in your bag or on your desk acts as a visual cue to drink regularly throughout the day. Set reminders or use an app - Timed reminders on your phone or tracking apps can gently prompt you to sip throughout the day. Create hydration cues - Pair drinking water with other daily habits, such as having a glass of water 30 minutes before or an hour after every meal, or whenever you get up from your desk. Infuse water with natural flavours - If you're not a fan of plain water, try infusing it with slices of lemon, lime, cucumber, or fresh mint. Eat your water - Include more hydrating foods in your diet, such as watermelon, cucumber, celery, and strawberries, as they help support hydration naturally. How can you tell if you are dehydrated? Signs to look for Ann explained the signs that you or someone else is dehydrated. Some early indicators of dehydration are: Feeling thirsty Feeling hungry (often disguised as thirst) Dry mouth or lips Fatigue or sluggishness Difficulty concentrating or feeling foggy Dizziness or lightheadedness Dark yellow urine or urinating less frequently Headaches Muscle cramps (after exercise) Sunken eyes Recommended reading: Ann said: "Mild dehydration is common, but over time, even slight deficits in fluid intake can impact your wellbeing. "Water is vital to the transportation and absorption of nutrients, which can have a significant knock-on effect on your health. "Staying hydrated supports not just physical health, but also mental clarity and consistent energy levels throughout the day.'
