What happens to your body when you stay up late during holidays?

Introduction: Staying up late during the Spring Festival can harm organs like the heart and brain; prioritize health and adjust habits.

You might think staying up late is just "sleeping a little later," but in reality, your body is "working overtime and suffering" on your behalf.

During the New Year, it's rare to relax, playing cards, chatting, and scrolling through our phones; before you know it, it's almost midnight. Many people think, "Since I don't have to work tomorrow, I can just catch up on sleep."

But the body does not keep accounts that way. It won’t wait for you to catch up on sleep; it will quietly keep track, and then come to you for the final tally.

The heart is the one that suffers the most.

Have you ever felt your heart racing and even a bit anxious when staying up late?

That's the heart being "forced to work overtime." It should be resting, but since you aren't sleeping, it has to keep going. After several nights of pushing through, the heart feels like legs that have been running for days—sore and tired—but you still make it keep running.

At this time, if you drink some alcohol and play cards to get excited, your blood pressure will fluctuate, and it becomes easier for heart problems to occur. There's a good reason why many people suffer from heart attacks in the emergency room during holidays.

Is your mind covered in a layer of fog?

After staying up late, do you feel like your mind is sluggish the next day? Struggling to remember things? Finding it hard to speak?

Sleep is the brain's "cleaning time." When you sleep, your brain clears away the waste accumulated during the day. If you don't sleep, it's like the garbage just piles up.

It's manageable for a day, but after a few days, my mind feels like a room filled with garbage, unable to turn or function properly. My reactions go slow, and my memory worsens; all of this is due to that.

The liver can quietly gain weight.

During festivals, people tend to eat well and indulge in rich foods, and with staying up late, the pressure on the liver increases significantly.

The liver is supposed to process fats at night, but when you stay up late, its rhythm gets disrupted, and it can't process the fats, causing them to accumulate. This is how fatty liver develops.

Moreover, after staying up late, you will crave fried chicken and sweet drinks, not because you're greedy, but because your hormones in your body are out of balance.

I don't feel full and always think I haven't eaten enough. As a result, I stayed up late without losing weight; instead, I gained weight, particularly around my belly.

The face is the hardest to deceive.

You can't see other organs, but you can always see the face, right?

Staying up late just once can make your face look a bit duller and lose some firmness. This is because staying up increases the breakdown of collagen. What is collagen? It’s the "spring" that keeps your face tight. Without this spring, your face can sag.

No amount of skincare can replace getting a good night's sleep.

What should I do after enduring so much?

If you really can't avoid it, remember three points to suffer a little less:

A 20-minute nap at noon the next day is sufficient. Be sure not to sleep from the afternoon until evening, as that would be like staying up all night again. Waking up after 20 minutes will refresh your mind, allowing you to sleep normally at night.

For breakfast, avoid eating deep-fried dough sticks and steamed buns. After staying up late, your body is experiencing inflammation, and consuming fried or sugary foods is like adding fuel to the fire. Instead, opt for foods like eggs, oatmeal, and fresh fruits.

Go out for a walk. Don't just lie there scrolling on your phone; the more you scroll, the more tired you get.

Going out to soak up some sun for about ten minutes is more effective than taking a nap.

In the end, the joy of the New Year comes from being together and feeling relaxed, not just from those few hours of staying up late.

Let's go to sleep soon tonight. If we feel refreshed tomorrow, then that's what really matters for the celebration.
