Hyperthermia is a characteristic sign of inflammatory processes. But some people are worried even the rise of the thermometer column to low values. Especially if for a long time or even constantly in the evening the temperature is 37 degrees. This indicator is called subfebrile and quite rarely indicates serious pathologies.
Why does the temperature sometimes rise to 37 degrees by the evening?
Man, like all living beings on the planet, obeys biorhythmic fluctuations, including temperature fluctuations. Early in the morning, between 4 and 6 o'clock, the thermometer will show the numbers from 36.2 to 36.5. A little later this value will reach the standard (36.6), and in the evening it can be from 37 to 37.4 degrees. This is absolutely normal, if not accompanied by a bad state of health.
Other causes of fever to subfebrile values:
- the second phase of the menstrual cycle;
- lactation or pregnancy;
- menopause;
- active lifestyle, professional sports;
- recent eating;
- rapid metabolism;
- mental agitation;
- Hard work day;
- too warm clothes;
- use of hot and alcoholic beverages.
