Thermoregulation of the body mainly depends on external conditions, but it can also be disrupted by various internal processes. As a rule, this is facilitated by infectious and inflammatory diseases accompanied by fever. But in some cases there is a fever without temperature - the reasons for this phenomenon in women are quite numerous, and include both pathological conditions and quite normal physiological responses.
Causes of chills without fever at night for women
Subjective sensation of cold and shivering in the body during sleep is a typical symptom of diabetes mellitus. This endocrine disease is usually accompanied by excessive sweating, so that the body quickly cools down even under comfortable external thermal conditions.
A night chill without a temperature in women happens and against the background of other factors:
- depression and chronic stress;
- supercooling on the eve of going to bed;
- prolonged strain of the muscular system during the day;
- hyperhidrosis - excessive sweating, up to the wetting of the sheets;
- increased blood viscosity;
- propensity to thrombosis, including hemorrhoidal veins;
- osteochondrosis and inflammation of the joints;
- migraine headaches .
In addition to tremors, these problems are accompanied by other unpleasant symptoms, for example, irritability, pain syndrome, myalgia.
Causes of chills and nausea without fever
In most cases, these clinical manifestations are characteristic of cardiovascular pathologies. They are often combined with sharp jumps in blood pressure, which provokes rapid expansion and narrowing of the capillaries, which disrupts the thermoregulation of the female body.
Also, the sensation of trembling, dizziness and nausea is inherent in craniocerebral injuries, usually as a result of concussions. In addition, depending on the severity of the damage observed vomiting, disorientation in space, a tendency to fainting, impaired consciousness.
In addition, the following symptoms can cause such conditions and diseases:
- tuberculosis;
- syphilis;
- acute circulatory disorders;
- vegetative disorders;
- Raynaud's syndrome;
- Sluggish chronic infections;
- spasms of blood vessels;
- hypothyroidism and other pathologies of the endocrine system, functions of the thyroid gland;
- internal bleeding;
- neuroses and neuralgia.
It is important to note that chills and nausea are characteristic clinical manifestations of various exotic fevers that arise after insect bites - mosquitoes, mosquitoes, flies, beetles. If the frost begins immediately after coming from vacation, it is necessary to visit an infectious disease doctor urgently.
Frequent attacks of vomiting are dangerous because of the loss of a large amount of moisture and a violation of the water-electrolyte balance, hypoxia. Therefore, with the symptoms under consideration, it is important to monitor the drinking regime, consuming an increased volume of fluid per day, and as soon as possible contact the doctor.
Other causes of chills without fever in women
Feeling of cold and trembling may well be a variant of normal physiological reactions to fluctuations in the level of sex hormones, changes in the work of the ovaries. In women, chills are often an early sign of the onset of menopause, pregnancy, part of premenstrual syndrome. Because of the hormonal imbalance, the processes of thermoregulation change, which causes the body to lose heat and cool quickly.
Similar conditions are also accompanied by other symptoms - hot flashes, pain in the lower abdomen, sweating, skin rashes, mood swings.
