News Topical, Digital Desk : In today's busy work culture, staying up late and working long hours has become a symbol of achievement for many. But behind this rush, a silent danger lurks. Recent research suggests that irregular sleep and working 55 hours or more not only increases fatigue but also puts serious strain on the heart.
According to the US Centers for Disease Control and Prevention , long working hours, night shifts, and irregular schedules are among the major risk factors for heart disease. A joint analysis by the WHO and ILO found that in 2016, millions of people died from heart disease and stroke due to causes related to long working hours. People who worked 55 hours or more a week had a significantly higher risk than those who worked 35 to 40 hours.
Experts explain that sleep is not just a time for rest, but also a time when the heart and blood vessels repair themselves. Chronic sleep deprivation increases inflammation, increases the risk of plaque buildup in arteries, and can disrupt blood sugar and metabolism. It also increases the risk of obesity and diabetes, which are major causes of heart disease.
What is the problem with night shift?
Our bodies operate on a 24-hour circadian rhythm; night shifts or irregular sleep-wake times disrupt this coordination. Research supported by the National Institutes of Health found that people with highly irregular sleep schedules have nearly double the risk of heart disease. Sleep disturbances increase blood pressure, increase stress hormones like cortisol, increase inflammation, and worsen cholesterol and sugar control, all of which put additional strain on the heart.
What are the symptoms?
According to experts, if a person consistently sleeps less than 6 to 7 hours, the body remains in a state of stress. This increases heart rate and blood pressure, and in the long run, can increase the risk of heart attack or stroke. It's important to pay attention to some early signs, including high blood pressure even at rest, chest discomfort or palpitations, shortness of breath with even mild exertion, persistent fatigue, or feeling lethargic throughout the day. If these symptoms persist, it's important to consult a doctor.
What should you do?
To protect your heart, try to get 7 to 9 hours of quality sleep daily. Maintain a regular bedtime and wake-up time, limit heavy meals and screen time at night. Even if you work a night shift, maintain regular meal, exercise, and rest times. Light activity or walking during the day improves blood flow. Avoid alcohol and excessive caffeine, and reduce stress through yoga or meditation. Also, get your blood pressure, cholesterol, and sugar levels checked regularly.
