The sleep-wake cycle is regulated by the pineal gland hormone melatonin.
Assessing the level of this hormone in the blood helps diagnose circadian rhythm disorders that can lead to insomnia.
There can be many reasons for such difficulty falling asleep, in particular, lack of fatigue, spending a long time in bed during the day, irregular bedtime, anxiety, illnesses that cause itching or pain.
An excess of the hormone leads to an increase in the volume of the thyroid gland, increased heart rate, weight loss, excessive sweating, and increased neuropsychic excitability.
And as a result - to insomnia. With a lack of the hormone, there is a tendency to obesity, dry skin, and decreased excitability.
It is believed that a lack of calcium and magnesium can cause numerous sleep disturbances during the night.
In addition, calcium works with tryptophan to produce the sleep hormone melatonin.
Chronic insomnia is also one of the initial symptoms of magnesium deficiency.
Sleep paralysis can occur at any time as it can be caused by a number of factors, including medication and substance use, mental illness, sleep deprivation, and other types of sleep disorders such as narcolepsy.
This usually occurs for the first time in childhood or adolescence.
