A majority of the human body is made up of water, which is why staying hydrated so important. It can be confusing to determine how much the average person should drink in a day, especially in situations like when it’s hot outside or when you’re exercising. There are even consequences to not drinking the right amount of water, such as dehydration or overhydration. The National Health Service (NHS) typically recommends drinking between six to eight glasses of fluid, including water, every day. But the US National Academies of Sciences, Engineering, and Medicine has determined that an adequate daily fluid intake is 15.5 cups (3.7 litres) per day for men and 11.5 cups (2.7 litres) per day for women. However, this fluid intake accounts for drinking plain water as well as other beverages and food that contain water, like fruits and vegetables. The amount of water one should be drinking each day can also vary depending on the situation. According to the Mayo Clinic, those who are working out should be drinking extra water before, during, and after a period of exercise. This especially goes for any activity that makes you sweat, because drinking water helps replenish the fluid your body lost. People in hot or humid weather should be drinking more water than usual because of how much they’re sweating, which contributes to fluid loss. Meanwhile, in areas with higher altitudes like the mountains, dehydration can become more common. The Mayo Clinic suggests that people lose bodily fluids when they have a fever, are vomiting, or have diarrhoea. As such, it’s important that people are consuming extra water when they’re sick. Other conditions that might require increased fluid intake include bladder infections and urinary tract stones. Feeling thirsty and passing dark-coloured, strong-smelling urine are some of the initial signs that you could be dehydrated. Other symptoms include feeling sluggish, feeling light headed, or having a dry mouth. Drinking milk, water, and fruit juice is also a good way to maintain hydration. However, people should bear in mind the amount of sugar that can be contained in sweetened drinks. Tea and coffee may also help with hydration, though people should try to keep track of how much caffeine they’re consuming. While it’s important to know whether you’re drinking enough water, the Mayo Clinic suggests it’s likely that nothing is wrong with someone’s water intake if they rarely feel thirsty and their urine is clear, or a light yellow colour. It is possible to drink too much, however, it’s rarely a problem for someone with healthy kidneys. Still, overhydration can occur when the body retains or collects too much water. Some athletes who participate in endurance events, especially marathon runners, can be prone to taking on too much fluid. This can lead to water intoxication and dangerously low sodium levels, which is referred to as hyponatraemia. In order to help the body to relieve itself of excess water, as well as relieve pressure on the heart and other organs, doctors may prescribe diuretics or water tablets that promote the production of urine.

Sebastian Vettel was back in the Formula 1 paddock on Thursday as he unveiled a number of “bee hotels” at the Suzuka circuit. The four-time F1 world champion, who retired last year, is the leading voice in the sport on the environment and climate change – and continues to use his platform within the sport even after leaving the grid. Present at his favourite track in Japan, Vettel invited all the drivers and teams to turn two of the track on Thursday, where he has formed a set of specially-created insect hotels. The message behind the project is to spread the word of the importance of biodiversity in our ecosystems. Each team was able to customise and paint their hotel, while the kerb at turn 2 was painted yellow and black. “I want, with this project, to create awareness about the importance and the subject of biodiversity,” Vettel said. “[The bee is] the perfect ambassador for us around this project and idea to highlight the importance of biodiversity, because it stands not just for the bee but for all the other insects, so we see the bee as our ambassador. She will help us stress this very important message. “It’s very exciting and a lot of work and passion went into the project. Hopefully this is just the beginning of an initiative and projects around the world… standing up for biodiversity, which is not just insects, it’s all types of animals. “But it’s more than that as well: it’s all types of plants, all types of organisms, bacteria. And even more than that, we have to celebrate variety, not just in human beings, but also in nature – and we have to protect it.” Lewis Hamilton was full of praise for his former rival for passionately raising awareness for issues close to his heart. “It’s great to see that he’s found his purpose,” Hamilton said. “It’s great to have Seb back this weekend. He sat down and told all the drivers about these plans. “To be honest, in the history of the sport, I don’t know any other driver who’s ever been so outspoken and shown real compassion for the world outside of this little world that we’re living in. It’s really great that he’s utilising his platform. “I always just hope that with the things that he’s doing, for example, that he inspires the other drivers to do something here – maybe in their own lane. “But we all need to come together in this world to have a positive impact; to spread love, to spread compassion, to raise awareness for a lot of the problems – and there’s obviously millions of problems that we need to address – but biodiversity is for sure.” Read More Lewis Hamilton says ‘something’s up’ at Red Bull – if Max Verstappen struggles in Japan Lando Norris calls for ‘harsher penalties’ after Max Verstappen incident George Russell insists 2023 has been his ‘best season ever’ despite Singapore crash
