Weird question

Mitzki5

Why is it that I am always 2-3 lbs lighter between going to sleep and waking up? I have been weighing myself immediately before bed and as soon as I wake up. It's not the time of day either because I work swing shift so sometimes sleep at night and sometimes during the day. I have a quality scale. This just seems very odd and I can't explain. Told you it was an odd question.

It's from water retention. At night you are retaining a bit of water from having eaten relatively recently. In the morning you haven't eaten recently, and your body isn't retaining as much fluid. You wouldn't see as much of a difference if you weighed after breakfast instead of before.

I see the same thing when I happen to weigh at night. Weighing that much really isn't needed, but I like seeing the water retention impact of what I've eaten that day, and it's given me a better sense of what my real weight probably is when I know I'm retaining fluid. So on days where I was in a rush and couldn't weigh until the evening and I see a number 2lb higher then my trend for the week, I know that 2lb will be gone the next morning and all I'm really seeing is that I'm still on track.

You exhaled water vapor during the night , Or during your sleep if it wasn't at night

Part of it is due to water evaporation during the night. Part of it is due to urination. It is actually a little easier to pull water out of the blood while you're lying down.

I figured it must be evaporation. Just shocked at how much water is lost.
