Nowadays, many people stay up late for many reasons, such as working, playing games, surfing Facebook, shopping online or breastfeeding. However, staying up late has many potential health risks. Do you know the harmful effects of staying up late? Scientists have stepped in to find the answer to this problem.
You know that staying up late is not good for your health. However, what consequences can this habit bring? Scientists around the world have done many studies on this issue. The results show that this habit can increase the risk of premature death.
Scientists at Northwestern University (USA) and the University of Surrey (UK) conducted a study of 433,000 adults in the UK about the habit of staying up late for 6.5 years. The results showed that people who slept late were 10% more likely to die than those who slept early. And this result holds true for both men and women of all ages participating in the study. In addition, the analysis data also shows that people who stay up late often have high rates of cardiovascular diseases, diabetes, respiratory diseases, gastrointestinal problems and psychological depression.
It is difficult to know how these results affect each other, and scientists still do not have a clear answer as to why staying up late is harmful to health. However, researchers all agree on the following hypothesis: When the biological clock is out of sync with society, the entire biological system is disturbed and many aspects of our lives become stressed. than. Constantly staying up too late makes the body tired like you go through a long journey flying from one area to another with the change of time zones. This causes damage to the body.
The habit of staying up late can increase the risk of dangerous diseases, but some people do not care about this
If you stay up late on the weekend, you have to get up early the next day, which will make your body feel like it’s switching to a new time zone. If you go through it every day, your body will be stressed and your health will decline.
In a study done with 24 healthy people whose bedtime varied every day for three weeks. The results showed that their resting metabolic rate dropped by 8%. Assuming no change in exercise regimen and food intake, this could lead to an increase of about 5.6kg a year.
In addition, staying up late also makes it easier for us to sleep at the weekend. This can be uncomfortable for the body and make it harder to wake up on Mondays.
Weight gain and depression: In 2012, researchers analyzed a data set of 65,000 Europeans and found that staying up late can cause weight gain. There is also research showing that people who stay up late are more likely to develop depression and are more likely to engage in unhealthy behaviors such as smoking.
Diabetes: A 2015 study tracked the sleep of 447 middle-aged adults for a week and found that staying up late can also lead to insulin resistance – a precursor to diabetes – and lower jaw function. low HDL cholesterol, high triglycerides and body mass index. These metrics persisted even after adjusting for habits such as exercise, smoking, and alcohol use.
Staying up late also leads to lack of sleep the next day, making it difficult to focus on work
Increased risk of certain diseases: When staying up late, if you wake up early the next day, the body will be stressed and less efficient. In addition, lack of sleep can also increase the risk of heart disease, metabolic disorders, diabetes and obesity.
Growth retardation and reduced resistance in children: For children and teenagers, staying up late also has a huge impact, especially on height and the immune system. In a child who sleeps late, growth hormone will be inhibited, causing the child to slow down in height and weight compared to other children of the same age. In addition, staying up late also makes the internal organs of the body not have enough time to recover and repair the damage. This affects the resistance in children.
Memory loss: Staying up late also leads to lack of sleep the next day, making it difficult to focus on work and suffer from “goldfish brain”. This is because a lack of sleep shortens the duration of the deep sleep and REM stages of the sleep cycle, which are responsible for processing information and storing memories from short-term to long-term memory. When this process is hindered, memory decline is inevitable.
Staying up late is not a good habit, if you are a person with this habit, change today to maintain the best health.
