Child filling glass with water

You might be encouraging your child to go outside more often this summer. There’s nothing like spending time in the sun and letting their imagination go wild while they play. Your loved one might get so invested that you need to tell them to come back in. Especially during these warmer months, dehydration can affect their well-being and oral health. Here are four signs you should watch out for.

Feeling Hungry

If your child seems like they have an insatiable appetite you can’t curb, then dehydration might be the cause. The hypothalamus in the brain is responsible for feeling thirsty, but it also does this for hunger. So, if your child wants more after they’ve eaten, then you might want to give them a glass of water instead. That said, some of the signs of an empty stomach cross over with thirst, so it’s easy to get them mixed up.

Fewer Tears When Crying

When kids are dehydrated, their body will start to conserve fluids for critical functions, like maintaining blood volume and brain function. Without drinking enough, the production of tears may decrease dramatically or stop entirely. So, if your loved one is crying but nothing is coming out, then you should give them water as soon as they feel better.

Darker Urine

A simple way you can check if your child is dehydrated is by their urine. It tends to look darker and more concentrated if there’s a problem. Aim for a pale yellow color, so make sure your child drinks plenty of water to avoid trouble. Not only that, but if they aren’t urinating as often, then it can also be a sign to watch out for.

Dry Mouth

Saliva is a crucial part of digestion and keeping the mouth moist. Kids can’t produce enough of it when dehydrated, which can lead to dry mouth. This condition can increase their risk of dental problems. They won’t be able to wash away harmful bacteria as easily, meaning they may linger for longer and cause cavities or even gum disease.

If you notice their breath has been bad or their lips are chapped, then they might be struggling with dry mouth. Thankfully, having them drink some water or eat crunchy vegetables can help.

In the end, spending time outside might be a staple for the summertime. It’s best to ensure your loved one is safe by watching out for the signs of dehydration. By stopping it, you can ensure their growing smile and body stay in great shape.
