An increase in body temperature during ovulation is a normal physiological phenomenon in women. Basal body temperature remains elevated after ovulation and before menstruation begins.
1. Increased Body Temperature During Ovulation and Before Menstruation
For healthy women with normal ovulation, basal body temperature (BBT) can be divided into two phases: the low-temperature phase and the high-temperature phase. BBT cycles continuously and reflects a woman's physiological status.
- Low-Temperature Phase: At the start of the menstrual cycle, body temperature decreases and remains low for about 2 weeks.
- High-Temperature Phase: During ovulation, body temperature rises and remains elevated until the next menstrual cycle begins. This explains why women often feel an increase in body temperature before menstruation.
If the high-temperature phase persists for more than two weeks, it may indicate pregnancy. Conversely, if body temperature remains low throughout the menstrual cycle, ovulation likely did not occur. Additionally, a woman’s basal body temperature can fluctuate depending on diet and lifestyle habits.
Changes in body temperature during the menstrual cycle can cause both physical and emotional changes. The table below outlines the variation in body temperature throughout the menstrual cycle.
2. Body Temperature Changes as a Premenstrual Symptom
Changes in body temperature are part of Premenstrual Syndrome (PMS), a condition affecting most women of reproductive age. PMS includes both physical and emotional symptoms, such as:
- Physical Symptoms: Acne, breast tenderness, fatigue, insomnia, bloating, constipation or diarrhea, headaches, back pain, sore throat, muscle and joint pain, runny nose, loss of appetite or overeating, and a feeling of increased body temperature (similar to fever).
- Emotional Symptoms: Difficulty concentrating, memory problems, tension, irritability, mood swings, crying easily, anxiety, and depression.
Although this is a normal physiological phenomenon, PMS can cause significant discomfort in some women. Symptoms such as elevated body temperature and severe cramps can lead to fainting episodes or distress.
3. Management of Premenstrual Syndrome
PMS symptoms, including increased body temperature during ovulation, are heavily influenced by diet and lifestyle. Simple adjustments, such as adopting a healthier lifestyle and daily supplementation of vitamins C, D, E, and folic acid, can alleviate severe symptoms. Key recommendations include:
- Regular physical activity
- A balanced diet rich in fresh vegetables, legumes, and fruits
- Avoiding salty, spicy, sugary foods, carbonated drinks, caffeine, alcohol, and stimulants
- Sleeping at least 8 hours per day and managing stress
- Drinking adequate water and avoiding strenuous physical activities during menstruation
If symptoms persist despite lifestyle changes, consulting a gynecologist is advised. Medical treatments, such as medications, can effectively alleviate most PMS symptoms.
