How Much Weight Do You Lose Overnight : How It Works ?

If you have started a diet or seen a dietician, you are most likely advised to weigh yourself daily. This is because your weight can fluctuate during the 24-hour time. For example, if you consider yourself first thing in the morning, you will weigh less than if you step on the scale just before you hit bed.

What you have eaten and drunk during the day will surely influence your weight, but your weight also changes overnight while you are asleep.

Significant ways in which your body loses water are through sweating and urinating. During the day, you can replace the water that you lose by drinking more at night; you are least likely to replace the water you lose through sweating and urinating.

All you need to know!



On average, you sweat around 25ML per hour of sleep under standard temperate conditions. If you sleep for about 8 hours, that’s about 200ML of sweat per night, equating to a drop in weight of at least 200 grams overnight. You might even sweat more, leading to further weight loss if it is very hot at night. 

Furthermore, vigorous exercise during the day also increases your core temperature, and this can persist after you stop exercising, increasing sweating overnight. Even eating spicy foods before bed can lead to a lot of sweating while asleep.

There are some physiological stats like menopause and fever during which you can sweat considerably every night. But heavy sweating, which results in you changing your sheets, will lead to even minimum figures on the scales in the morning.

Any weight that you would lose due to sweating overnight is short-term, unfortunately as you start drinking and rehydrating, the weight will also return.


Average urine production is around 0.5 to 1 milliliter per hour. So if you weigh about 70 kg and sleep for 280 hours, you should produce 280ML of urine every night.

If you are not drinking anything during the night and empty your bladder before you weigh yourself, your weight can be up to half a kilogram lighter than before you hit the bed. As with excessive sweating at night, this weight will return as soon as you rehydrate.

Carbon dioxide Weight Loss

Your metabolism is a process that goes inside your body which allows you to function well. It includes breaking down the food to build and repair the body. Your body will burn some energy throughout this process to maintain itself.

It is excreted as carbon dioxide exhaled whenever you breathe out something metabolic rate drops by around 15% during sleep.

Therefore, despite this drop, you should know that you will excrete significant carbon dioxide during sleep. This will be less if you consider nighttime carbon dioxide loss, but it will still make you light when you step on the scale first thing in the morning.

Does Sleep Play a Crucial Role in Weight Loss?

The recommended and most enough sleep time for adults is from 7 to 9 hours overnight. Still, not everyone keeps to this sleeping routine, and several studies also show that sleeping less than the recommended schedule can be linked to diabetes and obesity.

Instead of building muscle mass from constant physical activity, you are stuck with your weight gain, even from unbalanced hormones, an unhealthy diet, and fatigue.

So you have to turn off the lights or even reduce when just about to hit the bed. Your gadgets produce blue lights, and avoiding using devices right before you hit the bed is advisable. Instead, you can read a book or listen to a podcast while you are in bed.

What’s your diet before you end up sleeping

Whatever you eat affects your sleep quality undoubtedly; you have to avoid having a lot of heavy meals and alcohol just before your bedtime, which might lead to heartburn. You must drink a lot of water during the day for hydration, which will keep your digestive system working.

You must avoid soda drinks because they have a lot of caffeine, and they can stay with you even after 2:00 PM, so be careful whatever you are choosing during the late hours.
