How many calories do u burn when u sleep?

My friend said you burn calories even when you're sleeping, which sounded a bit strange to me. I wanted to confirm. How many calories do you burn when you sleep, really?

You burn about 40 to 50 calories per hour during sleep. Honestly, don't waste money buying expensive smartwatches just to track this; they are mostly inaccurate and that money is better saved for your annual health insurance premiums.

You burn about 50 calories an hour while sleeping. To support this nighttime metabolism, it's best to have a light, vegetarian dinner like dal-khichdi at least 2-3 hours before bed instead of a heavy meal.

I was looking this up recently out of curiosity. Turns out our brain and organs use quite a bit of energy at night, burning roughly 40-50 calories per hour depending on our body weight. Pretty interesting stuff!

According to my fitness tracker, I seem to burn about 380 calories during my typical 7.5 hours of sleep. It's just a general estimate based on my age and height, but it's consistent every night.

I completely understand how stressful it is to track every single calorie to feel in control of your health. It is totally normal to wonder about this. We burn around 350-400 calories in an 8-hour sleep just by breathing and staying alive, so your body is working well even when resting.
