| 0:20.5 | Hello and welcome to another episode of Science on the Menu, a podcast by EFSA, the European Food Safety Authority. |
| 0:29.2 | My name is Ed Bray and I work in EFSA's Communications Unit. |
| 0:33.6 | And today I'm joined by Sylvia Valtweña from EFSA's human nutrition team. |
| 0:39.3 | Hi Sylvia, how are you doing? |
| 0:41.3 | Hi, Ed, very well. How are you doing? |
| 0:43.3 | Yeah, I'm doing very well, thank you. |
| 0:45.3 | And I'm really looking forward to this conversation. |
| 0:48.3 | Today we're going to be talking about hydration, a very topical subject right now, |
| 0:53.3 | given that we're coming into the summer season. |
| 0:56.1 | And we hear a lot about hydration and the fact that it's important, but maybe some of us don't |
| 1:03.6 | know actually what it really is. So that's my first question to you. What is hydration, actually? |
| 1:10.1 | Well, hydration is the maintenance of an equilibrium between the water and electrolytes we have in the body. |
| 1:15.9 | We need to have the right concentration and the right amount. So that means an equilibrium between the water that goes in and the water that goes out. |
| 1:24.9 | When you're talking about the water that goes out, you're talking about going to the |
| 1:28.5 | bathroom, going to the bathroom, through urine and feces, but also sweating or breathing. We can lose |
| 1:36.3 | huge amounts of water through those. And you said that it's an equilibrium, so it's a balance, |
| 1:43.5 | actually, hydration. It's keeping the body in a state |
| 1:47.8 | where these levels are balanced. Is that right? Yeah, that's correct. And I imagine then that when we |
| 1:53.5 | become dehydrated, we're out of balance. Is that right? We are. Either because we lose |
| 1:59.3 | water, salts, or both, and we are not able to restore them on time. |
| 2:04.6 | You know, it depends on the level, the consequences of dehydration. Because if we lose 1% of the water, more or less, in one day, that is very easy to restore. So we don't even feel it. Because the function is so important that we have a lot of control mechanisms |
