According to scientists, the most exhausting decade in a person's life lasts from 40 to 50 years. During this period, biological changes occur simultaneously in the body, which are combined with a large life load, writes the Daily Mail.
According to Michelle Spear, professor of anatomy at the University of Bristol, this condition can be described as a “biology-load mismatch.” The body is still able to produce energy, but it does so less efficiently, while the demands on it remain high.
Key factors in fatigue include decreased muscle mass, reduced mitochondrial efficiency, poor sleep quality, and increased stress response. Even brief bouts of stress or late nights can be significantly debilitating, unlike in younger years.
The scientist adds that it is during this period that people typically perform the most leadership and caregiving functions, which further increases cognitive and emotional load. At the same time, individual feelings of energy can vary significantly from person to person.
The good news is that after age 60, energy levels often increase and stabilize, even as physical performance declines. Regular strength training, adequate sleep, stress management, and a balanced diet can help preserve muscle mass and support metabolic health.
Scientists emphasize that the goal is not to restore the energy of a 20-year-old, but to properly manage the body's resources and prioritize recovery.
