Do you need to drink eight glasses of water daily?

It is a widely held belief that a person must drink at least eight glasses of water in a day, however, a new study has contradicted this view which says that it might be “too much”.

A recent study, published in Science, found that the recommended eight glasses of water were more than the required amount, BBC reported.

As per the estimates, people only need about 1.5 to 1.8 litres of water as they also intake water from food.

“The original estimate of two litres a day comes from a slight miscalculation,” Professor John Speakman from the University of Aberdeen told BBC.

“The water that we’d need to drink is the difference between the total water that we need to ingest and the amount that we get from our food.

“The way they estimated the amount from food was by asking people how much they eat.”

The scientist said that asking people how much they eat is a common practice to estimate the amount of water intake that comes from food. He, however, said that following this method could result in misestimation as people “under-report” the amount of their food intake.

The study

There have been countless studies to find the correct answer to the question but the surveys applied to small samples of people. However, this new study was conducted through collaboration across the globe, in which the scientists used a stable isotope technique.

The survey involved 5,604 individuals aged between eight days and 96 years old, from 23 different countries. Some of the hydrogen molecules were replaced by a stable isotope of the element called deuterium in a glass of water the participants of the survey consumed.

Deuterium is an element naturally found in the body so the rate of its elimination showed how quickly the water in the body turned over.

It was discovered that people with a higher water turnover generally need to drink more water, while energy expenditure is the biggest factor in water turnover.

‘Just an adage’

Meanwhile, CNN’s senior medical correspondent Elizabeth Cohen said that drinking more than needed water is just “an adage” and does “no harm” to the human body.

When asked how much water should people drink, Cohen said that people only need to observe the colour of their urine instead of counting the glasses of water they consume, to see if they are drinking enough water.

As per the study, a person is considered healthy and hydrated if the colour of their pee is pale straw. The “amber or honey” coloured urine indicates mild dehydration while “syrupy or brown ale” coloured pee shows that a person is experiencing “worrisome dehydration” which could be a sign of liver disease.

She said that the symptoms are well known in a country with hotter weather.

“If you’ve yellow pee, that’s not good,” she translated an Israeli song, saying that everyone needs to learn that.

The nomination of Ishaq Dar as deputy prime minister raises concerns.

A lot of doubts have been raised by Ishaq Dar, the foreign minister, being appointed deputy prime minister.

No reference to the Constitution, regulations, or any other law was mentioned in the Cabinet Division’s notification of the appointment.

What powers Prime Minister Shehbaz Sharif used to designate Ishaq Dar as deputy prime minister has come under scrutiny in light of this.

There are questions about the legal foundation for the deputy prime minister’s nomination as it appears from the notification’s phrasing that rules for the position have not yet been established, according to insiders.

Likewise, the announcement is vague about the deputy prime minister’s proposed authority.

Deputy prime minister would be purely symbolic, according to government sources, and would not be authorized to carry out prime ministerial duties. In Pakistan, the deputy prime minister has previously been nominated.

The PPP administration appointed Chaudhry Parvez Elahi as deputy prime minister.

Observe that Foreign Minister Ishaq Dar was appointed deputy prime minister on Sunday with Prime Minister Shehbaz Sharif’s consent; the Cabinet Division formally announced the appointment.

Dar holds the position of Pakistan’s fourth deputy prime minister. Previous appointments to the position of deputy prime ministers included Parvez Elahi, Zulfikar Ali Bhutto, and Begum Nusrat Bhutto.

The green colour of WhatsApp ‘angers’ some users.

After changing its display colour from blue to green, WhatsApp, which was before well-known for its blue motif, caused its users to hold divergent views.

New upgrades to the Meta app always spark a lot of discussion, regardless of how big or small the changes are.

Still, Meta-owned WhatsApp hopes that these modifications would “make it more accessible as well as easier to use” and offer a “modern, new experience” with relation to the updated display color.

A statement from the firm claimed that they had altered WhatsApp’s “looks and feels, including spacing, colors, icons, and more.”

Both iOS and Android users can now view the new WhatsApp update; the green tint on the latter has changed from the previous version.

However, iPhone users will notice that every display element, including the chat-list window and status bar, has changed with the recent design update. WhatsApp used to have a blue color scheme on iPhones.

Furthermore, the formerly blue links shared within the app are now displayed in green.

In addition, WhatsApp has made other improvements to improve its user experience outside of the color shift.
