Is cold water bad for you? Know the facts behind 5 myths related to water

Sydney. We know the importance of maintaining plenty of water in the body, especially in hot weather. But even for something as simple as drinking water, there is conflicting advice and a variety of beliefs. Is cold water really bad for your health? What about hot water coming from the tap? And what is “raw water”? Let’s dig deeper and find out.

Myth 1: Cold water is bad for you Some recent TikToks have suggested that cold water causes health problems by “shrinking blood vessels” and “disrupting digestion.” There is very little evidence of this. A 2001 study found that 51 (7.6%) of 669 women tested got headaches after drinking cold water, most of whom already suffered from migraines, and no such study has been repeated since. Is.

In 2012 it was observed that cold drinks caused discomfort to people suffering from achalasia (a rare swallowing disorder), but the study only included 12 participants. For most people, the temperature at which you drink water depends on personal preference and circumstances. Drinking cold water after exercise in summer or hot water to relax in winter will not make any difference to your overall health.

Myth 2: You should not drink hot tap water. There is some scientific truth hidden behind this belief. Hot water is generally a better solvent than cold water, so it can dissolve metals and minerals from pipes. Hot water is also often stored in tanks and can be heated and cooled multiple times. Bacteria and other disease-causing microorganisms grow better in warm water and can accumulate over time. It is better to fill your cup from the tap with cold water and then heat it in the kettle. Myth 3: Bottled water is better.

Although bottled water may be safe in some parts of the world due to pollution of the source water, there is no real benefit to drinking bottled water in Australia and similar countries. According to researchers at the University of Queensland, bottled water is no safer than tap water. It could also be tap water. Most people can’t even tell the difference. Bottled water usually costs (substantially) more than tap water and is worse for the environment, too. What about lead in tap water?

This problem came into limelight after the public health emergency in Flint, Michigan in the US. But Flint used lead pipe with a corrosion inhibitor (in this case orthophosphate) to keep the lead from dissolving. The city then switched water sources to sources without corrosion inhibitors. Lead levels increased and a public emergency was declared.

Fortunately, lead pipes have not been used in Australia since the 1930s. Although lead may be present in some older plumbing products, it is unlikely to cause problems. Myth 4: Raw water is naturally healthy Some people bypass bottled and tap water and go straight to the source.

The raw water trend emerged a few years ago, encouraging people to drink water from rivers, springs and lakes. There is also a website to help you find local sources. Supporters of this belief say that our ancestors used to drink spring water, so we should also drink it. However, our ancestors also often died from dysentery and cholera and had short life expectancies.

While it’s true that even highly treated drinking water may contain low levels of things like microplastics, unless you live somewhere very remote, the risk of drinking untreated water is far greater because it contains pollutants from the surrounding area. More likely to happen. Myth 5: It’s OK to drink water straight from the pipe.

As tempting as it may be, it’s probably best not to pipe water when watering plants. Water may have been sitting there for weeks or more in the hot sun, potentially causing bacteria to build up. Similarly, while drinking water fountains are generally completely safe to use, they may contain various types of bacteria.

It is useful (though not necessary) to run them for a few seconds before you start drinking such water so as to get fresh water through the system and not water that has been sitting there for a while. We are fortunate to be able to make choices about safe drinking water. Billions of people around the world are not so lucky. So whether you like hot or cold, or anything in between, feel free to enjoy a glass of water this summer. Just don’t smoke it from a pipe.
