Fatigue is something that is completely normal. Our body makes us feel tired when it wants us to go to sleep. During sleep, the body regenerates, the brain processes information and new connections are created. Scientists have not understood everything that happens in the brain during sleep, but one thing is clear: sleep is incredibly important for maintaining your physical and mental health. This also means that the feeling of tiredness is inevitable.
But tiredness and fatigue can get out of hand. If we constantly feel tired during the day or sleep poorly at night, this often means that something is wrong in the body.
Constant tiredness - causes
The sleep hormone melatonin is the substance that makes us feel tired. During the day, when light falls upon our eyes, receptors in the eyes tell the brain that it should not produce melatonin. When the light starts to dim, the brain begins to produce melatonin and we then become sleepy. But the daily rhythm of melatonin levels gets out of balance, for example, because we are surrounded more and more by lighting during the evening. A problematic issue is particularly daylight-mimicking bluish light, as is often emitted by smartphone displays. This has the effect that our brains cannot tell when it is becoming night - and that the daily cycles are displaced further and further backwards. The consequence: We find it hard to fall asleep, are torn out of deep sleep by the alarm clock and start the day completely tired.
The “happiness” hormone serotonin also determines whether we feel awake or tired. If a serotonin deficiency arises, this can cause constant fatigue. The situation is similar with the stress hormone cortisol. If the cortisol level is too low, which is a common feature of burnout syndrome, or if there is reduced kidney function, excessive fatigue and tiredness can result.
A mineral deficiency can also cause constant fatigue. Minerals such as magnesium, zinc and selenium energise our bodies, and especially our muscles. If we consume too little of them, one result is that we might feel tired and lazy.
Constantly tired - what to do?
If you are constantly tired, the best thing is to first understand its causes. Important hints about this, for example, can be provided by cerascreen®'s self-tests. The levels of the hormones melatonin, serotonin and cortisol can be measured using various tests, as well as the levels of the minerals zinc, magnesium and selenium. Depending on the test, you can wither take a small amount of blood or saliva as a sample for the tests. In the results report, you will then find out whether you have a deficiency or how the course of hormone levels looks over the course of the day.
You shall also receive recommendations in the results report on what you could do: such as spend more time in the fresh air during the day and setting your smartphone aside early in the evening to correct your melatonin levels and daily rhythms. And trying to relax so that you can normalise your cortisol levels. With mineral deficiencies, you can change your diet or counteract them using dietary supplements.
