Sleep, Inflammation & Your Long-Term Health

We all know a good night’s sleep helps us feel more alert and less cranky. But there’s a lot more going on behind the scenes, especially when it comes to your body’s long-term health. Turns out, how well you sleep can directly affect inflammation, which plays a big role in everything from immunity to chronic illness.

🧠 Sleep and Inflammation: What’s the Deal?

Inflammation is your body’s way of fighting off threats like injury or stress. But when it sticks around too long (aka chronic inflammation), it can lead to serious problems—think heart disease, diabetes, even depression.

Research from the National Institutes of Health shows that lack of sleep is tied to higher levels of inflammatory markers like CRP and IL-6, basically red flags for your health [1]. One study in Biological Psychiatry even found that just a few nights of poor sleep can spike these markers significantly [2]. So if you’re skimping on rest, your body might already be feeling it.

🛌 How Sleep Helps You Heal

Here’s the good news: deep, consistent sleep actually helps reduce inflammation. When you're in proper rest mode, your body:

• Lowers inflammation

• Keeps stress hormones like cortisol in check

• Strengthens your immune system

• Repairs and heals on a cellular level

So sleep isn’t just about catching Z’s, it’s about giving your body the time it needs to repair and protect itself.
