Trembling during sleep may be related to movements independent of our will, which usually occur early in sleep and are accompanied by falling or scare dreams, which are normal.
Some problems that can cause tremors and night movements:
- Restless legs syndrome, which is the movement of the legs regardless of the person's will;
- Night fever with chills and tremors that may manifest in the presence of infections, such as flu and urinary tract infections.
The general practitioner can help identify the problem, request tests to determine the diagnosis, and refer the specialist if necessary.
