In today’s fast-paced work culture, long hours and late nights are often seen as signs of success.

However, working 55 hours or more per week can seriously affect heart health.

Research from the Centers for Disease Control and Prevention shows that long working hours and night shifts increase the risk of heart disease.

A joint study by the World health Organization and the international Labour Organization found that millions of deaths in 2016 were linked to heart disease and stroke caused by overwork.

People working 55+ hours weekly data-face a much higher risk compared to those working 35–40 hours.

How Sleep Affects heart Health

Sleep is not just rest; it is when the heart and blood vessels repair themselves.

Chronic sleep deprivation increases inflammation in the body.

It promotes plaque buildup in arteries, raising the risk of a heart attack.

Lack of sleep disrupts blood sugar control and metabolism.

It increases the chances of obesity and diabetes, major risk factors for heart disease.

Sleeping less than 6–7 hours regularly keeps the body in a constant stress state.

This leads to a higher heart rate and elevated blood pressure over time.

Night Shifts and Circadian Rhythm Disruption

The body follows a natural 24-hour circadian rhythm.

Night shifts disturb this biological clock.

Research supported by the National Institutes of health shows irregular sleep patterns nearly double heart disease risk.

Disrupted sleep increases cortisol (stress hormone) levels.

It worsens cholesterol levels and blood sugar control.

Persistent stress places extra strain on the heart.

Warning Signs to Watch

High blood pressure, even while resting.

Chest discomfort or heart palpitations.

Shortness of breath during mild activity.

Constant fatigue and daytime sleepiness.

Feeling lethargic or mentally drained.

Seek medical advice if these symptoms continue.

How to Protect Your Heart

Aim for 7–9 hours of quality sleep daily.

Keep consistent sleep and wake times.

Avoid heavy meals and screen use before bed.

Exercise regularly, even light walking.

Limit alcohol and caffeine intake.

Manage stress through yoga or meditation.

Monitor blood pressure, cholesterol, and blood sugar regularly.
