Did you know that exercise, in addition to treating depression, can also relieve fatigue? It seems like it would do the exact opposite; if you are feeling tired, the last thing you might want to do is exercise or drag yourself to the gym to work out. But there is a scientific basis for the idea of doing physical exercise to overcome tiredness.
Brain chemistry plays an important role in giving you energy. Physical movement can stimulate a part of the brain and hasten the release of feel-good chemicals. The end result is that you can feel more alert and energize. Let’s look at three important chemicals that can make you feel more alert, alive and focused. These are serotonin, dopamine, and noradrenaline (norepinephrine).
Serotonin can make you feel more focused, emotionally stable, happier, and calmer, according to Hormone Health Network. It helps regulate your mood in a natural way. Regular exercise has been found to boost serotonin levels while it helps with cardiovascular health, improving strength and sustaining endurance.
This hormone can also help improve sleep levels when it is time to sleep. During the day it can help you be more focused.
Animal studies have shown that exercise boosts dopamine levels in the body. It can increase feelings of pleasure and reward as well. Overcoming tiredness with exercise is just one of the benefits as the effects of naturally increasing brain chemicals take place. This chemical messenger functions in the brain as reward, motivation, attention, memory, and regulation of body movements.
Noradrenaline, also called norepinephrine, helps mobilize the brain and body for action. It is the lowest during sleep; it reaches much higher levels during situations of stress or danger, in the so-called fight-or-flight response. Low levels of this hormone can cause lethargy (lack of energy) or a lack of concentration.
According to Healthline, physical exercise stimulates endorphins, which is where noradrenaline is found. Physical activity helps balance stress hormones, such as adrenaline.
Fatigue and exercise
The recommended exercise for people with chronic fatigue is aerobics; it boosts endorphins while it makes one feel energized. It has been found, through studies, that aerobics works on the central nervous system to increase energy as well as lessen fatigue. Building up oxygen levels in the blood, aerobics gives you energy. Exercise that includes stretching and strengthening the body is also important. Some people opt for yoga, Pilates, or tai chi as a calmer way to build the endorphins and feel better. Alertness can improve with walking and bicycling as well.
Serotonin, dopamine, and noradrenaline can be increased through exercise, giving your body a boost that might overcome lethargy, fatigue, and a lack of concentration. It is also an important part of staying healthy, both mentally and physically. Tiredness, except at bedtime, will be overcome during the day with just some simple actions. Start small and stay awake.
