Dr. Gloria Juan, a neurologist at Affidea Clínica Atenea, emphasized that feeling mentally exhausted is not a sign of weakness, but a manifestation of cognitive micro-stress. This phenomenon is caused by factors such as work overload, multitasking, and prolonged screen use.
“"Feeling mentally exhausted is not a sign of weakness, but a consequence of what we call cognitive micro-stress, caused by factors such as work overload, multitasking, or intensive screen use."
Sustained stress leads to a constant release of hormones like cortisol and glutamate, which can alter both brain structure and function. This situation particularly affects the hippocampus, crucial for memory and learning, and the prefrontal cortex, involved in decision-making, concentration, and emotional control. In the long term, it can lead to apathy, anxiety, irritability, demotivation, and even burnout syndrome. Dr. Juan also warned that chronic stress can reduce the generation of new neurons and increase the risk of neurodegenerative and cardiovascular diseases.
Meanwhile, Dr. Pablo Jover, a traumatologist at Affidea Clínica Tecma and Affidea Clínica Atenea, noted that current hyperproductivity encourages habits detrimental to the musculoskeletal system. Extended working hours, intensive screen use, and a sedentary lifestyle are associated with a higher prevalence of cervical and lumbar pain, joint stiffness, and muscle weakness. Lack of breaks and poor ergonomics contribute to repeated mechanical overloads, especially in the spine, shoulders, and wrists. Furthermore, overtraining without adequate recovery in highly active individuals increases the risk of tendinopathies and chronic muscle fatigue.
In the cardiovascular field, Dr. Víctor Girbés, a cardiologist at Affidea Clínica Sermesa Mislata, added that chronic stress and prolonged working hours not only affect the brain and muscles but can also cause sustained increases in blood pressure, palpitations, or heart rhythm disturbances that often go unnoticed. He highlighted the impact of excessive stimulant substances like coffee or energy drinks, which can elevate blood pressure, and a diet high in sodium, which promotes hypertension. These factors can also interfere with sleep quality.
Given this scenario, Affidea specialists recommend incorporating active breaks during the workday, maintaining good postural hygiene, sleeping 7 to 8 hours, respecting rest cycles, and consulting a specialist for persistent pain, recurrent migraines, or cognitive alterations. They consider it essential to include preventive check-ups and adequate rest habits, even in apparently healthy individuals.
“"The message is not alarmist, as not every symptom indicates a serious illness. But learning to listen to your body and acting in time is key to maintaining productivity without compromising health."
