1.How Lack of Water Affects You
More than half your body weight comes from water. So if your levels are off, it can show up in a surprising number of ways. Mild dehydration can make you feel tired and give you a headache. Even your mental focus, mood, and memory can take a small hit. And when you push yourself hard at the gym, all that sweating actually lowers how much blood you have for a bit.
2.Is Thirst a Sign I’m Dehydrated?
Yes, but no need to panic. That’s just how the body works. By the time you get the urge to quench your thirst, you’re already a little dehydrated. As long as you pay attention and snag a drink when your body tells you to, it’s not a problem. For older adults, the lag might be a little longer. So it can help to make a habit of drinking water, especially when it’s hot out or you’re feeling sick.
