We all know sleep is important, but did you know that just one sleepless night can harm your immune system? Even if you are healthy, missing sleep can cause inflammation in your body and weaken your ability to fight diseases.

When we sleep, our body makes special proteins called cytokines. These proteins help fight infections and reduce swelling in the body. But if you don't sleep, your body produces fewer cytokines, making it harder to recover from illnesses. White blood cells, which protect us from viruses, also become weaker. This means you are more likely to get sick.

The problem doesn't end there. If you often lose sleep, your body stays in a stressed state. This can lead to serious health issues like heart disease, diabetes, and even depression. Over time, your body struggles to heal itself, increasing the risk of long-term diseases.

So, skipping sleep for work or fun might not seem like a big deal, but it can have dangerous effects. Your body needs sleep to stay strong and healthy. The best way to protect yourself? Get enough rest every night!
