What are the main causes of sleep disorders?
In adults, the main causes are stress, anxiety and depression.
Waking up feeling like you didn't sleep well is quite common in people who experience:
- difficulty falling asleep;
- and/or one or more nocturnal awakenings;
- and/or waking up too early in the morning.
These nocturnal disturbances give the impression of having a unrefreshing and unrestful sleep. What is felt on the quality of the day that follows: feeling of fatigue, drowsiness, daytime sleepiness, increased nervousness, difficulty concentrating and memorizing.
These disorders can be punctual and occasional, following a disturbing event (annoyance, bereavement, short-term physical illness, noisy environment) or sometimes more long-lasting. We can then speak of chronic insomnia when these difficulties in sleeping occur more than 3 times a week and over a period of more than 3 months.
Adults frequently encounter insomnia problems, but some sleep disorders can also be observed in children.
What is the most common sleep disorder?
It's chronic insomnia.
In 2017, 13.9% of adults aged 18 to 75 suffered from it, with an unbalanced male/female distribution: 16.9% for women and only 9.1% for men.
What deficiencies can cause sleep disorders?
A wide variety of vitamins and minerals are needed by our body to function properly and maintain good health. A deficiency in any of these items below can quickly lead to several symptoms, including insomnia.
The real relationship between sleep anomaly and vitamin B12 has not yet been clearly established, studies are still in progress. Until now, it has been suggested that a deficiency in vitamin B12 could involve pathologies such as depression and that they could then trigger episodes of insomnia.
Vitamin D deficiency is largely caused by lack of sun exposure. When vitamin D levels are low, sleep disturbances can occur. Irregular levels of vitamin D, low levels or excessive levels of the vitamin, have been linked to sleep problems. Experts have validated that excess vitamin D is often responsible for daytime sleepiness. According to some research, the less vitamin D our body gets, the more difficult it is for it to sleep. To fight against vitamin D deficiency, it is recommended to include a nutritional supplement in your diet and to practice light therapy sessions that will allow your body to stimulate its secretion of vitamin D, especially during periods of low outdoor light in autumn. and in winter.
Anemia or iron deficiency can trigger a large number of symptoms. It has been proven that the lower the iron level, the more one can suffer from restless leg syndrome and the more the quality of sleep is affected. When the body lacks iron, it is more difficult to produce tryptophan, an amino acid necessary for the production of melatonin and serotonin. Serotonin, also called the "happiness hormone" has a direct impact on mood, cognition and behavior. While melatonin, called "sleep hormone" directly affects the sleep cycle. In this case, the practice of light therapy will stimulate the secretion of these hormones and therefore limit the effects of the lack of iron on the body.
How to cure sleep disorders?
Light therapy can resynchronize our biological clock.
The principle of luminotherapy consists in exposing oneself daily to “broad-spectrum ” white artificial light. The light emitted by the light therapy device used (lamp or bezel in particular) is comparable to that of the sun, minus the harmful rays, to compensate for a lack of natural exposure. This treatment is effective for people who wish to synchronize the rhythm of their body with their rhythm of life.
In the morning, light therapy stimulates the secretion of serotonin. Exposing our body to sunlight or a light therapy lamp will allow us to have sufficient serotonin levels to balance our internal biological clock. And this hormone plays an essential role in many areas: regulation of appetite, body temperature, stress management, pain, sleep rhythms...
Light therapy also regulates the secretion of melatonin at the end of the day to prepare the body for falling asleep. Melatonin is the hormone that helps us rest and fall asleep. Exposing yourself to light stops the production of melatonin and allows the body to activate and wake up more easily.
