It's common to hear phrases like "I don't exercise because I have no energy" or "my day is already exhausting enough." But, paradoxically, the solution to this lack of energy could be exactly what you avoid: exercise.
Although it may sound contradictory, science shows that physical movement not only consumes energy, but also generates it, transforming the feeling of exhaustion into vitality.
Exercise as an energy generator.
When you move, especially actively, you trigger a series of physiological and neurological processes that revitalize the body and mind. Here are some of the main mechanisms:
Release of adrenaline and norepinephrine: When you perform large or dynamic movements, your brain sends signals to the adrenal glands to release adrenaline. This hormone not only prepares the body for action, but also activates receptors in the vagus nerve (an essential link between the brain and the body) and promotes the release of norepinephrine in the brain, a neurotransmitter that increases your state of alertness and perceived energy.
Increased blood flow: Exercise increases blood flow, bringing more oxygen and nutrients to the cells. This increased supply of cellular energy reduces fatigue and increases the feeling of vigor, even after a long day.
Endorphin production: During exercise, the brain releases endorphins, the so-called “happiness hormones.” In addition to improving mood, they reduce the perception of exhaustion and generate a feeling of renewed well-being.
Regulation of metabolism: Physical movement activates metabolic processes that optimize the production and use of energy. In the long term, regular exercise makes your body more energy efficient, so you feel less tired even on the most demanding days.
Why do you feel more exhausted when you move less?
A low level of activity is a key factor behind a lack of energy. Staying inactive for hours causes the body to go into “save mode”, reducing circulation and slowing down the metabolism. In this state, even everyday tasks can become exhausting. On the other hand, regular physical activity revitalizes the body and breaks this cycle of inertia, alleviating the feeling of constant fatigue.
The virtuous circle of the movement
Exercise stimulates your nervous system and triggers various energizing processes that push you to keep moving. This positive feedback loop, known as the “body-brain energy loop,” transforms initial fatigue into a state of greater vitality. Although taking the first step may seem difficult, the benefits multiply as soon as you get going.
“I have no energy” is an illusion
The next time you feel too tired to exercise, remember that this feeling is usually temporary. It is often the result of a sedentary lifestyle and not a true lack of energy. Giving yourself the opportunity to move, even when you don't feel like it, is the key to unlocking that much-needed push.
Exercise doesn't drain your energy; it's an investment in your vitality. Instead of waiting until you feel strong enough to get going, get moving to generate the energy you lack. Your body and mind will notice, and the feeling of chronic fatigue will give way to greater vitality.
