If you feel that your menstrual cycle is affected by the seasons, you are not wrong. The menstrual cycle and hormones are easily affected by external factors. Lifestyle changes due to the change of seasons have a great impact on the menstrual cycle and sometimes this effect is not positive. Of course, there is no need to worry. Knowing why these changes occur makes us more prepared to deal with them, and the first step is to learn to control and balance our hormones. In the following, we examine the effect of season change on the period and the reasons for this effect.
Are menstrual cycles different in summer and winter?
The menstrual cycle is the first day of the period until the last day before the start of the next period. In summer, menstrual cycles are usually shorter; So if you feel the effects of the change in your menstrual cycle, whether your period is significantly shorter, or whether you are experiencing the symptoms or side effects of PMS more than any other time of the year, you should not be fooled.
There are scientific reasons for these changes. The more severe the climate change (for example, after traveling to a tropical country after living in sub-zero temperatures and very cold weather), the more likely you are to feel the effects of the change of seasons on your period. Although there may not be extreme temperature changes in our area, sometimes a wave of extreme heat sets in and ends after a few days.
In winter, we spend more time indoors, less active and eat more. This sometimes has a negative effect on premenstrual symptoms. Research has shown that women who are more physically active have more regular and controlled menstrual cycles than women who exercise less often. Winter can also affect the length of the menstrual cycle.
Reasons for the effect of season change on menstruation
1. Hormonal reasons
In summer, our body has greater amounts of Follicle-stimulating hormone Secretes (FSH). This hormone increases the chance of ovulation and, as a result, the menstrual cycle is shorter. FSH stimulates the growth and maturation of ovarian follicles so that the ready-to-fertilize egg is released during ovulation.
FSH secretion is usually elevated in the summer, the ovarian follicle becomes larger, and the number of ovulations increases. The length of menstrual cycles also decreases by 0.9 days. These changes have also been observed in women living in warmer climates. Of course, you should note that this time is the average reduction of menstrual cycles. This means that in some people there is no change or the change is in minutes, and in some this change is very obvious.
2. life style
Significant changes in the menstrual cycle in the summer may be due more to changes in other areas of life, not just because of the weather. Lifestyle strongly affects the menstrual cycle and the production of hormones. One of the main reasons for changing your period in summer is changing your habits, sleep schedule and even diet. In the summer, we spend more time outdoors, eating lighter foods, and eating more seasonal fruits and vegetables, which are different from the fruits and vegetables of the colder months of the year.
When the weather is nice, we tend to go out and be more active. Women who exercise regularly and are more fit are less likely to develop severe premenstrual syndrome (PMDD). They are also less likely to have heavy or irregular menstrual bleeding. A more active life usually means more regular menstrual cycles.
3. The amount of sunlight
Research has shown that increasing sunlight alters the menstrual cycle, not temperature. During the summer or in hot, sunny climates, the body produces more vitamin D. Low levels of vitamin D have been shown to cause Follicular phase And the menstrual cycle gets longer. Longer menstrual cycles are more likely to cause ovulation. On average, in winter, ovulation occurs in 71% of cases; While in summer this figure increases significantly by 97%.
Therefore, if more vitamin D increases the chance of ovulation, a deficiency in the winter months may also lead to anovulation in the menstrual cycle, which is usually longer. The presence or absence of sunlight has a great effect on mood, because sunlight, in addition to producing vitamin D, which helps secrete FSH, also produces Serotonin Also affects; Therefore, it is not surprising that severe seasonal changes have a large impact on the menstrual cycle.
In the hot and sunny seasons of spring and summer, we are more exposed to the sun, and this causes the body to produce more vitamin D and dopamine. Vitamin D and dopamine are associated with good mood and pleasure and improve mood, increase pleasure, motivation and concentration. Without them, the mood swings we experience during menstruation increase and become more difficult to overcome.
Less exposure to the sun can lead to seasonal affective disorder (SAD). Symptoms of this disorder include depressive symptoms, such as sadness, lack of interest in things we used to enjoy, feelings of hopelessness, and a desire to eat more carbohydrates.
4. Weight change
Weight change greatly affects the menstrual cycle. We usually gain weight in winter. There are many reasons for this, such as not going out in the winter as much as we do in the summer. Seasonal diet changes also affect our weight. Some of us lose weight by changing seasons, but not all of us do. Keep in mind that a yo-yo diet is not good for your health in the long run, and it is better to know your body better and have a balanced diet that is compatible with your menstrual cycle needs, energy level, activity and lifestyle.
There is a direct relationship between weight gain and the intensity and length of menstrual cycles. The amount of excess weight that can make a significant difference in menstrual cycles is not the same for different women; But if BMI Unhealthy (BMI) exceeds a certain level, it affects every woman’s menstrual cycle.
The stress hormone (cortisol) affects the hypothalamus. The hypothalamus is the part of the brain that is essential for regulating hormones. When the hormone cortisol affects the hypothalamus, the signals that the hypothalamus sends to the ovaries are disrupted, which delays or even prevents ovulation.
Recognize changes in the menstrual cycle and adapt to them
Although the effect of the change of seasons on the period does not only include the shortening of the menstrual cycle in summer, it is clear that summer affects menstrual cycles both because of the long, sunny days and because of the change in personal and social life. If you feel uncomfortable with the change of seasons, whether in the summer or during the colder months of the year, you can control your menstrual cycle and control your hormones with a healthier diet, regular exercise, going out and a healthier lifestyle.
What to do to get pregnant in winter?
Keep warm and exercise more. The important point is to increase mobility, because it causes chemical messengers to be released in a regular and uniform manner. Although ovulation occurs more during the summer, there is no statistical evidence to suggest that women are less likely to become pregnant during the winter months.
When are menstrual changes worrying?
If your mood swings are so bad that you have no motivation to go to work or enjoy things you used to enjoy, you should consider whether you have seasonal affective disorder or depression. It is best to talk to your GP about this.
If you do not have a period at all during the winter months, you should see a doctor, as this is abnormal and should be checked. Severe bleeding can also cause iron deficiency and anemia, and you should see your doctor.
