Staying up late disrupts the body's circadian rhythm; a doctor explains why it's important to sleep before 12 am.

News Topical, Digital Desk : Do you have a habit of staying up late at night? It might seem like it's 1-2 a.m., but it's okay... but the truth is, staying up past midnight quietly disrupts your heart's most important rhythm.

Why does the heart need rest at night?

After a pounding day, the heart slows down at night. Blood pressure drops, pressure on the veins decreases, and the body begins to repair itself. This is the time when the heart truly rests, but when we sleep late, this natural process is disrupted.

What happens if you stay up late?

When you stay up past midnight, the body remains in alert mode instead of going into rest mode.

• Stress hormones increase: Hormones like cortisol and adrenaline start getting produced in more quantity.
• Heart rate remains fast: Even at rest, the heart rate does not decrease normally.
• Blood pressure starts rising: The body thinks it's still daytime, so blood pressure doesn't drop.
• Pressure on the veins increases: Vascular tone cannot return to normal, due to which the veins remain under stress.

We may not feel these changes, but deep inside it starts tiring the heart.

Even a few nights can cause harm

If you think, “What difference does it make if you wake up occasionally?”, you’re mistaken. Research shows that even a few nights of short or late sleep can:

• May cause irregular heartbeat.
• Palpitations can trigger episodes such as pounding.
• Can put unnecessary strain on the cardiovascular system.
• Gradually this habit starts weakening the health of the heart.

Why is it important to sleep before 12 o'clock at night?

The most effective way to combat the day's hectic schedule, stress, and physical fatigue is through good sleep. Especially before midnight, as this is when the body and heart repair best. If you want to keep your heart healthy and strong for a long time, the easiest and most effective step is to get enough sleep.

Staying up late every night may seem like a small habit, but it gradually disrupts your heart's natural rhythm. Going to bed on time isn't just a way to relieve fatigue, it's also a protective shield for your heart. Therefore, try to prioritize sleep before midnight and give your heart the rest it truly needs.
