I didn’t really connect weight loss and sleep quality until long after the number on the scale had already changed. Over the four months it took me to go from 90.9kg to 75.3kg with jump rope, I was so focused on the scale that I almost missed a much quieter change: the way I sleep. Today I want to skip the weight loss talk for once and focus on what happened to my sleep along the way.
What My Nights Used to Look Like
Until last year, I’d lie in bed scrolling my phone well past midnight most nights. On days work ran late, I’d come home hungry and eat ramen or chips right before lying down, and those nights I’d wake up two or three times before morning. I’d hit snooze three times before actually getting up, and by afternoon meetings I was fighting to stay awake. At the time I just blamed it on being busy.
The First Thing That Changed After 100+ Days of Jump Rope
I started jump rope purely to lose weight, but somewhere past the 100 day mark, the first thing I actually noticed was how much earlier I was falling asleep. After 30 minutes to an hour of jump rope in the evening, my body was tired enough that I didn’t have the energy to keep scrolling once I got into bed. As the table below shows, my average bedtime moved from around 12:30 to 1:00 AM to closer to 11:20 PM. Waking up got easier too. One alarm is usually enough now, where it used to take several.

The Part That Didn’t Fully Fix Itself
If I stopped here, it would sound like jump rope solved my sleep problems completely. Honestly, it didn’t. I still wake up somewhere between 3 and 4 AM most nights, and after a late work dinner I wake up just as often as I used to. My night wake ups did drop from two or three times to about once a night, but they haven’t disappeared. Exercise alone didn’t fix everything, and that’s worth saying clearly.
Why Sleep and Weight Are So Tangled Together
Looking into it, there’s a fairly well understood chain behind why poor sleep gets in the way of weight loss. When you don’t sleep enough, ghrelin, the hormone that drives hunger, goes up, while leptin, the hormone that signals fullness, goes down. In plain terms: less sleep means a stronger appetite and a weaker sense of being full. That combination makes you hungrier, especially for sugar and late night snacks, which leads to overeating and can stall weight loss. I laid out that chain in the diagram below. Looked at the other way, sleeping even a little better seems to have made it easier for me to manage my appetite too.

The Bedtime Routine I Actually Keep Now
My sleep isn’t perfect, but a handful of small habits have helped. I leave my phone in another room an hour before bed, and I’ve swapped hot showers for lukewarm ones. When a late night craving hits, I drink a glass of water first before deciding whether I actually need food. Laying out my jump rope clothes the night before turned out to help too, since it makes the next morning’s session feel like less of a decision. I’ve mapped out the current routine in the checklist below.

Wrapping Up
Going from 90.9kg to 75.3kg changed my weight and my wardrobe in ways that were easy to see. The change in my sleep was quieter, but just as real. My bedtime moved earlier and my morning fatigue eased up, though I want to be honest that the early morning wake ups haven’t fully gone away. After 100-plus days, the biggest lesson was that weight loss and sleep aren’t separate problems you can fix one at a time. They move together, and they need to be managed together.
