Will staying up late cause muscle loss?

Muscle health is a factor that has a greater impact. For people, muscle problems can cause serious physical discomfort and undermine basic living abilities. Therefore, protecting muscle safety and health is an issue that people need to pay great attention to in life. There are many factors that affect muscle health, among which fatigue is one of the biggest factors. Let’s take a look at whether staying up late will cause muscle loss? I hope everyone can understand it.

Lack of sleep will cause muscle loss.

1. Reduce physical performance and thus reduce the quality of training.

The drowsiness caused by lack of sleep will prevent fitness enthusiasts from achieving the required training volume and intensity. Research experiments have shown that long-term lack of sleep will gradually slow down the body's reaction speed, reduce athletic ability, worsen athletic performance, and make one more easily fatigued. Therefore, the overall training quality will also decline.

2. A more important point is that lack of sleep will seriously affect the body's hormone secretion. When we are in deep sleep, the body secretes a large amount of growth hormones such as testosterone. I believe that many fitness enthusiasts are familiar with testosterone. For example, testosterone is the commander of muscle synthesis and one of the key links in muscle growth. Lack of sleep can affect the body's testosterone secretion, reduce testosterone concentrations in the body, and slow down muscle recovery and super recovery after fitness.

3. The side effect of "one increasing" and "the other increasing". Lack of sleep has not only the side effect of "one decreasing" on fitness, but also the side effect of "one increasing". This "increase" refers to the fact that lack of sleep will increase the concentration of cortisol in the body. Cortisol is not as well known as testosterone, but if we use an analogy, testosterone is the “success hormone” for sports and fitness, then cortisol is the “failure hormone.” Because cortisol has many effects, one of which is to break down muscles and cause fatigue. It also increases blood sugar and appetite. Excessive cortisol can also damage bones and skin, which is one of the reasons why people who lack sleep are more prone to osteoporosis and poor skin.
