6. Dehydration
Dehydration occurs when your body has lost a lot of fluid, and it can accompany a whole range of disorders and illnesses. By the point your body tells you that you have dehydrated and need to up your intake of fluid, then you are already in the more severe stages of dehydration and will need immediate attention.
You can prevent the condition of dehydration by taking in plenty of fluid – water is usually best, though not always tap water; eight glasses per day are recommended by most health practitioners, though it’s important to mention that the number might be a little bit higher or lower depending on your environment (are you losing a lot of fluid?) and your body weight. If you are severely dehydrated, you might also faint from your symptoms, and will likely need fluid immediately by that point, either by traditional methods or via a saline-IV intake.
