Ruth Alexander speaks to Professor John Speakman at the University of Aberdeen in Scotland, who explains why your age, sex, weight, and other environmental factors such as air temperature, humidity and altitude all make a difference.
Dr Nidia Rodriguez-Sanchez, senior lecturer at the University of Stirling in Scotland, explains why our bodies need water and what happens if we drink too little, or too much.

@35ozgurThanks for the best information 🎉
@MikaEmilovna-s7hI keep a mug with very cold water with ice. The colder the more I was willing to drink. It’s working!
@janiekcarney5482I just keep a large container of liquid available with my favorite ice!!! When it’s really cold It’s easier to drink for me!
@janiekcarney5482A cup of broth sounds wonderful! Great idea!
@janiekcarney5482I question whether marathons are dangerousness. You aren’t using good judgment when you push yourself too hard.
@janiekcarney5482Foods vary in water. Soups and stews have more water.
@janiekcarney5482No one wants to count fluids that aren’t just water! I disagree with that! Fluid is fluid and the calories are separate from that. Some people need extra calories and some don’t. Fluids can be nutritious!
@janiekcarney5482Each person is different! How much caffeine you consume!! How much sweating you are doing.
@janiekcarney5482Victoria must be drinking a bit more😶
@dpvlog3859I can't drink much water 😥 If I drink i have to go to pee frequently. I feel bored 😫... What should i do??? Let me know plz🙏

@KitzandbitzBody mass is a critical factor.
Age is another and genetic factors.
I think I need to learn drinking properly. Greeting from Penajam North Paser, East Kalimantan ❤
@FukutenshiYoufanWhy do I even watch it when I am on dialysis and dream of just a glass of water daily. I wish I had these problems (I am allowed to drink 600ml a day incl. water content in all my food)
@katrinlausch3078💧Water is the essence of life! 💦 Do you really know how much water you drink each day? 🧐 Our bodies are about 60% water 🚰 and every cell depends on it to stay alive 🌿! Without enough water, we can feel tired 😴, get headaches 🤕, or even lose focus 🧠. So start your day with a glass ☀️ and don’t forget to stay hydrated throughout the day 💙 Health, energy, and freshness are yours! 🌈🥤💪

@winsandarnaing6673Commentary: BBC Chinese’s Biased Coverage of Taiwan’s Recall Campaigns Undermines Media Integrity
In any democratic society, the role of media is to report facts and hold power accountable — not to act as a mouthpiece for any political faction. Yet, BBC Chinese has consistently demonstrated a clear bias in its recent coverage of Taiwan’s recall movements, betraying the journalistic neutrality expected of a global public broadcaster. This troubling pattern deserves scrutiny by the international community.
1. Selective Framing and Agenda-Driven Headlines
BBC Chinese repeatedly frames recall efforts initiated by Taiwanese citizens in a negative light, using emotionally charged phrases such as “political vendetta” or “retaliatory recalls.” Meanwhile, it avoids or downplays the very reasons behind these democratic actions — public dissatisfaction, political misconduct, or broken promises. By oversimplifying grassroots democratic processes as factional struggle, BBC Chinese misleads international readers and diminishes the agency of Taiwanese voters.
2. Delegitimizing a Legal and Democratic Process
Recall elections are a constitutional right in Taiwan, safeguarded by clear legal procedures and thresholds under the Civil Servants Election and Recall Act. Every successful or failed recall represents tens of thousands of real, law-abiding votes. Yet BBC Chinese frequently questions the legitimacy of these actions, often quoting pro-government scholars without presenting the voices of dissatisfied constituents. This selective coverage stigmatizes legal democratic behavior and disrespects voters’ rights.
3. Lack of Editorial Independence in Taiwan Bureau
There are increasing concerns that certain journalists or editors at BBC Chinese’s Taiwan bureau maintain close ties with a specific political party, compromising editorial independence. Repeatedly citing the same political commentators while ignoring voices from recall organizers or affected citizens betrays the basic principle of balanced journalism. Even in opinion pieces, fairness and diversity of perspective are non-negotiable.
4. BBC Must Uphold Its Global Reputation
While the main English-language BBC often retains its professionalism and impartial tone, its Chinese-language arm has repeatedly failed to meet the same standards — especially on politically sensitive topics like Taiwan. This double standard risks turning BBC Chinese into a political tool, damaging the BBC brand’s global credibility.
⸻
🟦 Our Call to BBC Chinese:
1. Conduct an internal review of editorial practices and staff affiliations.
2. Ensure balanced coverage, giving space to all voices — not just those aligned with the ruling party.
3. Respect democratic mechanisms, and stop framing lawful recall efforts as illegitimate power plays.
A healthy democracy requires multiple voices, and the media must rise above partisanship to protect truth. If BBC Chinese truly values its global integrity, it must stop acting as a partisan enabler and return to its journalistic mission: to report honestly, fully, and fairly.
Good!!
@English-Care-by-Aminur-RasulPeople who work in the office often overlook to drink water due to their overwhelming tasks and tight deadlines. It's necessary to always remind ourselves for drinking water to stay hydrated. Dehydration can occasionally lead to kidney disease.

@dannymoorhouse1174😂😂😂😂😂😂😂
@RichRich-x5uI drink too much water i guess, thats why i feel dizzy quite sometimes, thanks for the information
@misyelh252Our body might be 90% water by mass, but its a closed system surrounded by a huge magnetic field (Earth), making the mass factor far less important. Our blood is about 25% water by count, making the purity and filtration process more important when not considering sweating.
@avenomaEverybody has those stupid large heavy bottles. I take a little bottle, very light and i refill it.
@pellier08Why does she say [blod]
It is [bl^d]
