So how much water should I drink?
That’s actually not an easy question to answer. So many factors affect our needs from what we eat to the weather. Obviously there are times when more water is appropriate, like after/before intense exercise or if you are in extreme heat. In other words: If you body is losing water (like sweating), then replenishing those fluids is essential. .. But unless you are an extreme athlete or spend a lot of time in a hot climates you probably need less than what you’ve been previously told.
Listen to your body. This is my “go to” advice for most health practices because our body is packed full of useful signals to help us keep it happy… with one little snag: The problem with over-hydration is that a symptom of drinking too much is dry mouth and excessive thirst. So there may be a period of “challenging your body’s signals” while it gets back to a more balanced state.
