Health: Brain and heart health is determined by sleep time, not hours of sleep...

A new scientific report suggests that going to bed late and then shifting to longer sleep times can disrupt the body's internal biological clock. Experts say that maintaining a consistent sleep and waking time is more important than total sleep duration, as this rhythm is beneficial for both the brain and heart.

The study was conducted jointly by sleep scientists from the University of Exeter in the United Kingdom and Harvard Medical School in the United States. It has been published in the British Journal of Sleep Medicine and the National Geographic Health section. Researchers found that sleep timing has a profound impact on sleep quality and overall health. Staying up late and trying to make up for lost sleep by sleeping late the next day can lead to circadian rhythm disruption.

Irregular sleep times negatively impact brain function, concentration, and decision-making. Additionally, it increases the risk of diseases like heart disease, obesity, high blood pressure, and diabetes. The study analyzed the sleep patterns, lifestyle, and health indicators of over 40,000 participants long-term. The average age of the participants was between 18 and 65 years.

Professionals who sleep late should ensure consistent sleep schedules.
For those who are forced to stay up late due to their profession, such as doctors, media personnel, IT professionals, or night-shift workers, researchers recommend maintaining as consistent a sleep routine as possible. Even if the sleep time isn't at night, sleeping and waking up at approximately the same time during the 24-hour day and night cycle helps balance the body's biological clock. According to experts, even if you have to sleep during the day, it's important to ensure it's deep and uninterrupted.
