Even mild dehydration (1–2% body weight loss) can impair cognitive function, mood, and exercise performance.
A good starting point is half your body weight in ounces. Adjust up for exercise, heat, and altitude.
During extended fasts, intense exercise, or hot weather, plain water may not be enough. Add sodium, potassium, and magnesium.
Make it part of your daily routine. CalTrax can remind you to stay hydrated alongside your macro tracking.
