Can Working Out Delay Your Period?

Can working out delay your period? It’s a common question, and the answer isn’t always simple. Here’s what you need to know.


When it comes to menstrual cycles, there are a lot of variables that can affect when and how often a woman has her period. Routine workouts can be beneficial for many other aspects of health, but exercise can also have an impact on your period. It’s possible that too much exercise or working out at certain times may delay your period and lead to irregular menstrual cycles. In this article, we’ll discuss how exercising can affect your periods and what you need to know in order to manage the effects of exercise on your menstrual cycle. We’ll also look at some tips for managing delayed periods when working out and how to stay healthy during workouts.

What Happens to Your Body When You Exercise?

Exercising is an important part of a healthy lifestyle and it has many benefits for your body. Regular exercise can strengthen muscles and bones, improve your cardiovascular health, help control your weight and much more. But did you know that exercising can also affect your menstrual cycle? Let’s take a look at how exercising can impact your body and what you can do to manage it.

Hormonal Changes

Exercise has the potential to trigger a variety of hormonal changes that can affect everything from metabolism and hunger levels to menstrual cycles and reproductive health. The most significant of these are increased levels of endorphins—the “feel good” hormones that elevate mood, reduce stress, ease pain, and boost confidence. Other hormones involved in metabolism and reproduction, including cortisol and prolactin, may also be affected by exercise.

In women who are menstruating regularly, exercise can cause a delay or even a complete cessation of menses. However, this should not be taken as an indication that the body is unhealthy or at risk for infertility. In fact, studies suggest that this is usually caused by a hormonal shift during intense workouts which may cause progesterone production to rise significantly. This disruption in the normal cycle typically passes within 1–2 months after ceasing strenuous exercise. For some women however, an increase in exercising can lead to more regular periods due to an overall improvement in metabolic health which establishes healthier estrogen/progesterone ratios — although it is important to consult with a medical professional if menstrual irregularity persists for longer than two months or concerns arise over issues such as fertility or other health considerations.

Physical Changes

Regular exercise causes your body to undergo numerous physical changes, many of which can influence the timing of your period. During periods of intense physical activity, your metabolism speeds up. This increase in metabolism burns more energy and uses more of the stored fat in your body, both of which can lead to weight loss. Weight loss can cause your hormones to become unbalanced, resulting in a delay or complete stop in menstrual cycles.

Also, intense exercise produces an increase in endorphins that suppress the hormone GnRH responsible for triggering ovulation and the menstrual cycle. When you put too much stress on your body through physical activity and strenuous exercise it may not respond by releasing enough GnRH, thus delaying or stopping your period altogether.

It’s important to understand that while exercise can have an impact on your menstrual cycle, it is not always indicative of a health issue or medical condition. On the contrary, regular exercise may make periods more regular and reduce PMS symptoms experienced during menstruation!

Exercise and Its Effects on Your Menstrual Cycle

Regular exercise can have many positive impacts on your health. However, can it have an effect on your menstrual cycle? You may have heard of people talking about how intense workouts can delay their period and wondered if it was true. This article will explore the relationship between exercise and menstrual cycles to help you understand the potential effects of exercise on your cycle.

Low Body Fat and Amenorrhea

Having a low amount of body fat can disrupt your menstrual cycle, sometimes leading to periods becoming much less frequent. This is a condition known as amenorrhea, and it is quite common in women who engage in vigorous exercise, particularly those involved with sports like distance running or gymnastics. A decrease in estrogen levels can sometimes lead to irregular or skipped periods, which in turn may be caused by lower-than-normal body fat levels caused by intense exercise.

When amenorrhea occurs due to dieting or physical activity, it is often referred to as “functional” amenorrhea. When this type of amenorrhea happens due to low body fat, it is referred to as “relative” amenorrhea. Weight loss can also cause relative amenorrhea if the body fat drops too low. Lowering your calorie intake too severely or exercising too heavily has been linked with skipping one’s period until normal eating and exercising habits are restored. For example, a study published in Medicine & Science in Sports & Exercise showed that runners who completed marathons (while underweight) missed an average of three consecutive menstrual cycles following the event – their periods would only comeback when they gained more weight and burned fewer calories during runs

High Intensity Exercise and Delayed Menstruation

Women who engage in high intensity exercise, such as running or cycling for long distances, are at risk for delayed periods due to a drop in their body mass index (BMI). The amount of fat in one’s body can also affect when a woman has her period; women with higher BMI levels are more likely to have regular menstrual cycles than those with lower BMI levels. Other factors that can contribute to delayed menstruation include lack of proper nutrition, excessive stress, and over-exercising.

High intensity exercise has been linked to the release of hormones that affect the reproductive system. High-intensity activities can cause temporary fluctuations in hormones such as estrogen, progesterone and luteinizing hormone (LH), which can lead to irregular menstrual cycles. Additionally, when exercising at such a high intensity your body is also burning increased amounts of energy allowing you time to recover without going into starvation mode; this prolonged exposure to low-energy state may also trigger a delay in menstruation.

The effects of high intensity exercise on menstrual cycles simply underscores the importance of listening to your body and eating properly during any physical activity. It’s especially important not maintain an overly restrictive diet while engaging in strenuous workouts. Additionally, supplementing your diet with iron, zinc and B vitamins that women need during menstruation is sometimes helpful for maintaining regularity in the cycle if you are engaging in moderate-to-high intensity exercise on a regular basis.

Tips for Managing Your Menstrual Cycle While Exercising

Getting regular physical activity is great for your overall health and wellbeing, but for women, it can also have an effect on your menstrual cycle. It is possible that your menstrual cycle may be affected by increased exercise, making it arrive late or earlier. In this article, we’ll discuss some tips for managing your menstrual cycle while exercising.

Eat Enough Calories

While it’s important to ensure that you are eating a balanced diet that includes enough calories while you are exercising in order to avoid a nutrient deficiency, it is equally as important to make sure that you are eating the right types of foods. For example, foods high in healthy fats and proteins such as nuts, seeds, whole grains, legumes and leafy greens can help regulate your hormones and strengthen your bones. Eating enough within the recommended calorie range for your age and gender can also help keep your periods regular. Additionally, reducing or eliminating refined carbohydrates (white bread and pastries), added sugars (sodas and candy bars) and processed meats (hot dogs and sausage) can help reduce PMS symptoms like bloating, cravings, irritability, headaches and fatigue that can occur during the luteal phase of menstrual cycle.

Monitor Your Exercise Intensity

When you’re exercising, it’s important to pay attention to your body and monitor your intensity levels. During your menstrual cycle, you may need to adjust your routine as changes in hormones can affect how your body responds to exercise. Vigorous activities should be scaled back during the first few days of your period while a moderate, consistent exercise routine can be beneficial. Proper pacing will help manage fatigue and regulate stress levels. If you feel too fatigued or uncomfortable, consider rest or reduced intensity sessions. Make sure your workout program includes a range of exercises that focus on both aerobic and anaerobic activities, which will help to maintain energy levels throughout the month.

Take Time for Recovery

Any type of exercise can disrupt your menstrual cycle, but it’s important to be mindful of your body and give it time to recover after intense exercise. Try scheduling days off from exercising so you’re not placing too much strain on your body. Stress is one of the biggest factors that affect hormones, including those that control the menstrual cycle, so make sure to keep yourself well-rested and get plenty of sleep. Additionally, be careful about exposing yourself to extreme weather or poor air quality during workouts – these can both throw off estrogen levels. You should also consider eating a balanced diet and ensuring adequate nutrition levels. Lastly, staying hydrated is essential for helping maintain optimum hormonal balance. Achieving a balance between exercise and proper rest will help reduce stress levels, which will encourage a healthy female reproductive system and make managing hormone changes easier.


Research to date shows that exercise can affect the menstrual cycle, but not in a uniform way. An individual’s response to exercise will depend on a variety of factors including the duration, intensity, and type of exercise as well as the individual’s overall physical and mental health.

Overall, moderate-intensity aerobic activity (for example brisk walking) is most beneficial for women with menstrual irregularities or those hoping to maintain regular menstrual cycles. Intense forms of aerobic exercise and resistance training are usually not recommended for women with these goals. Other lifestyle modifications such as reducing stress levels, maintaining a healthy body weight, getting adequate sleep, and eating an appropriate diet may be more beneficial for fetal menstruation than only changing your workout routine. There are also various medical treatments available for irregular or absent menstruations.

For any woman looking to regulate her menstrual cycle through exercise, speaking with a healthcare provider should be considered before making drastic changes in their workout routine or lifestyle habits. Everyone is different; what works for one woman may not work or represent best practice for another. Ultimately having regular periods is important so that any potential health conditions can be identified early in order to prevent further long-term difficulties.
