Sleep Deprivation Effects: In today’s busy life, people often cut back on sleep and spend time completing tasks, meeting deadlines or scrolling on the phone late at night. It may seem minor in the beginning, but in reality lack of sleep gradually affects almost every part of the body. Sleep is not just a time for rest, but it is also the time when the body repairs itself and gathers energy again. If you do not sleep for 7 to 9 hours daily, then gradually its effect on heart, brain and metabolism becomes clearly visible. Let us tell you about it.

Has the worst effect on the heart

A study published in the American Journal of Lifestyle Medicine shows that the risk of heart diseases increases manifold in people who get less sleep. This includes problems like high blood pressure, stroke and coronary heart disease. Due to continuous less sleep, the body remains in a state of mild stress. Both blood pressure and heart rate increase and the level of stress hormones also increases. This difference may not seem much for a few days, but if this happens for weeks and months, it has a deep impact on heart health.

Metabolism deteriorates

The effect of lack of sleep is not limited to just fatigue, it also disturbs your metabolism. According to research, taking less sleep affects the hormones that control appetite. Leptin decreases and ghrelin increases. The result is that when there is lack of sleep, people feel like eating more sweets and high carb snacks. In the long run, this also increases the risk of obesity and type-2 diabetes. Especially in men, if they get less than six hours of sleep continuously, the risk of diabetes has been seen to be higher than in women.

Effect on mental also

If you have ever felt irritable after lack of sleep, then understand that it is not just a matter of mood. Consuming less sleep continuously increases anxiety, depression and emotional burnout. Due to lack of sleep, the part of the brain that controls emotions becomes more active, while the activity of the part that takes calm decisions slows down. This is the reason why people with lack of sleep get angry quickly, feel more stressed and also face difficulties in relationships with others.

How to improve sleeping habits?

The good thing is that sleep quality can be improved with some simple habits. According to health experts, young people need 7 to 9 hours of sleep every day and elderly people need at least 7 hours of sleep. For this you can make some changes-

  • Sleeping and waking up at a fixed time every day.
  • Stay away from screens like phones and laptops before sleeping.
  • Avoid caffeine and heavy food at night.
  • Keeping the room temperature cool and calm.
  • Do light meditation, reading or stretching before sleeping.
