Do you feel exhausted these days? Between a busy schedule and fluctuating hormones, it’s understandable why many women feel fatigued. The good news is that there are ways to navigate these moments and still feel like your best self!

Keep reading to learn the main reasons behind your fatigue and our best tips for improving your energy levels.

Common causes of fatigue in women

1. Menstrual cycle hormones

In general, there are distinctive hormonal changes that happen over the course of a full cycle.1

How does your menstrual cycle affect your energy levels?
Menstruation Days 1-5 Estrogen and progesterone are at their lowest, so you may feel more tired than usual.
Follicular phase Days 6-14 As the body prepares for ovulation, estrogen and testosterone start to rise, causing energy levels to rise.
Ovulation phase Day 14 Once an egg gets released, estrogen and testosterone are at their peak levels, and you may feel a boost in energy.
Luteal phase Days 15-28 Estrogen and testosterone hormones start declining and the body begins producing progesterone. This is around the time that PMS symptoms start to arise for some people.

2. Iron deficiency

You might be iron deficient if you often experience dizziness, weakness, and fatigue. Iron deficiency symptoms might first be mild but can develop further if not treated. Women are more likely to be deficient in iron, especially during menstruation and pregnancy.2 Always check with your healthcare practitioner to confirm any deficiencies.

3. Menopause

While menopause is a natural part of aging, it can bring uncomfortable symptoms. Most women start to experience menopause around age 50, though it could start as early as your late 30s. During menopause, your egg supply decreases and the body starts to produce lower levels of estrogen and progesterone.3 This can cause various physical and mental changes such as hot flashes, mood swings, and fatigue.4

4. Stress

Everyone has felt the effects of stress, but men and women experience the effects of stress differently. According to a 2016 study, women are twice as likely to experience severe stress and anxiety compared to men.5

Women report more physical and emotional symptoms of stress compared to men.6 The Canadian Mental Health Association reports that women tend to react more to chronic stressors like time constraints, meeting others’ expectations, marital relationships, children, and family health.7

5 ways women can support their energy levels

1. Work with your menstrual cycle phases

Learning how to work with your cycle is a life hack that can help you make the most of your energy. Tracking your monthly cycle can help you match your hormones with your output, especially for exercise and productivity. There are a variety of period tracking apps, like Clue or Eve by Glow, that can help you with this. But for now, here are some tips and ideas to help you work with your cycle:

  • Menstruation: Use this time for rest and reflection.
  • Follicular: As energy levels rise, so does your enthusiasm. This is the best time to try new things, start new projects, or take care of difficult tasks.
  • Ovulation: This is when your energy levels will peak so it’s the best time to prioritize fun and social activities.
  • Luteal: Energy levels might be decreasing with estrogen levels dropping off, so this may be a good time to lighten your load and prioritize self-care over to-do lists to fill up your cup.

2. Move everyday

When you’re tired, getting up and doing a workout is probably the last thing you want to do. But it’s the best thing you can do in those moments! Exercise increases dopamine and serotonin (feel-good) chemicals levels in the brain, which helps to improve mood and energy.8

During your menstrual cycle, the hormonal changes that occur within the body might make it easier to do certain types of exercise at different phases. Try to coordinate your workout intensity with the phase you’re in.

How to exercise in each stage of your menstrual cycle
Menstruation Lower intensity Walking, stretching
Follicular phase Higher intensity Running, cycling, dancing, heavy weight training
Ovulation phase Higher intensity HIIT, running, kickboxing, rowing
Luteal phase Lower intensity Pilates, yoga

3. Eat for energy

Do you notice how you feel sluggish after a big meal? That’s because foods high in sugar or carbohydrates can increase your blood sugar levels, which causes fatigue.9 Being mindful of what you eat is an effective way to maintain healthy energy levels.

Whole grains, fruits, vegetables, lean protein all help to nourish the body with essential vitamins and minerals that support energy metabolism. And don’t forget to keep drinking water! Being dehydrated has a significant impact on your energy levels.

4. Get quality sleep

Don’t underestimate the power of good beauty sleep for your energy levels. Unfortunately, when it comes to quality sleep, women often get the short end of the stick. In fact, women are 40% more likely to have insomnia compared to men.10 In general, adults should strive for seven to nine hours of sleep every night to feel refreshed.11

Here are some tips to help you fall asleep and stay asleep:

  • Avoid caffeine later in the day
  • Invest in a comfortable mattress
  • Keep your bedroom cool and dark
  • Write down your to-do list for the next day
  • Create a relaxing wind-down routine free from electronics
  • Take a sleep supplement

Sisu Melatonin can help you fall asleep more easily, sleep longer, and wake up less frequently during the night.

5. Prioritize self-care

It’s often said that the most important relationship is with yourself, but many women fail to prioritize self-care. Make time for self-care and notice how much more energy you’re able to pour back into your life.

Self-Care Ideas for Women:

  • Go on daily nature walks
  • Practice yoga/stretching
  • Take a bath
  • Read a book
  • Get creative, (writing, painting)
  • Practice positive self-talk

Sustain your energy

If your energy levels are not where you want them to be, there are a few actions you can take to put the spring back into your step. Taking the right supplements, moving every day, getting quality sleep, and prioritizing self-care can all support healthy energy levels.
