6 Winter Period Effects: You May Like to Know

Any change in season not only impacts the weather but also changes your menstrual cycle. Chilly temperatures and shorter days can influence your menstrual health; from irregular periods to intensified premenstrual symptoms, winters affect your period. 

1. Hormonal changes in winter 

Your body responds to seasonal shifts through changes in hormonal balance. Decreased sunlight exposure reduces the production of neurotransmitters that affect mood. Simultaneously, longer nights increase melatonin (a sleep hormone) levels. Consequently, these hormone fluctuations can impact estrogen and progesterone, which regulate the menstrual cycle. 

2. Impact on period regularity

Due to winters, it is less likely to predict periods. Common causes include reduced physical activity, winter stressors such as seasonal affective disorders (SAD), or fatigue. Besides, the weak immune system during winter makes the body more susceptible to infections and stress, disrupting menstrual cycles. 

3. Menstrual cramps

Women often complain about intensified menstrual cramps during winter. This is mainly due to vasoconstriction, in which blood vessels respond narrowly to cold temperatures. 

Conversely, cold weather can slow uterine blood flow, leading to painful periods. Moreover, colder weather causes muscle stiffness, leading to more severe cramps. 

4. PMS symptoms in winter

Premenstrual syndrome (PMS) symptoms can also worsen the menstrual symptoms. These may include mood swings, fatigue, and intense food cravings that occur due to: 

• Limited sunshine: Lack of sunlight leads to vitamin D deficiency and decreased serotonin levels, making people feel irritable and highly emotionally sensitive. 
• Trigger cravings: During colder months, you tend to crave foods that are high in calories and contain sugar, resulting in bloating and irritability associated with PMS. 

5. Seasonal affective disorder (SAD) 

A seasonal affective disorder (SAD) is a type of depression associated with seasonal changes. Common symptoms associated with SAD are low energy, persistently low mood, lethargy, abdominal pain, and difficulty concentrating. 

6. Changes in menstrual flow

Cold weather during winter also affects your period flow. Therefore, it is very common for women to experience heavier or prolonged bleeding or notice lighter periods. Variations in women's periods mainly come from metabolic slowdown and dietary changes. Let’s discover them in detail. 

• Metabolic slowdown: During winter, the metabolic rate slows, influencing uterine contractions and blood flow. 
• Dietary changes: Not eating a balanced diet or missing out on essential nutrients, such as iron-rich foods during winter, can affect overall health, including menstrual health.

How can you manage period health in winter?

By now, you must have adopted techniques to help you manage winter-period troubles. It is essential to maintain your menstrual health during colder seasons to help you avoid discomfort and reduce troubles: 

• Stay warm: Keep your abdominal area warm. Use heating pads or warm clothing to relax the vessels.

• Hydration: It is important to stay hydrated during winter, especially during your period, to combat bloating and promote overall health. 
• Exercise lightly: Avoid strenuous exercise during periods to avoid extreme discomfort. Instead, exercise lightly, under the guidance of experts, to help relieve pain. Additionally, practicing yoga can also help reduce period pain. 
• Eat balanced meals: To strengthen your immunity, incorporate seasonal fruits such as oranges, carrots, sweet potatoes, and others that suit your taste and preferences into your diet. 
• Take Supplements if Needed: Exposure to sunlight is vital and a natural way to improve vitamin D levels. However, if you are not getting enough vitamin D from sun exposure, discuss it with your doctor, who might suggest taking supplements. 

When to see a doctor?

Certain signs warrant you need not delay and visit a doctor immediately when experiencing some changes in your menstrual cycle during winter:
