Period fatigue: how to fight period tiredness

Period fatigue is normal, but you don't have to settle for it.


Many women feel tired in the days leading up to, and during, their period. There are many factors that can contribute to period fatigue, but don’t worry! At Key, we have spent years researching and meticulously formulating your Key for Menstrual supplement, which is designed to combat symptoms like period fatigue.

What causes period fatigue?

There are many different things that can cause you to feel tired during your period. Before we get started, remember that if your fatigue is extreme or persistent, you should talk to a doctor.

With that said, let’s take a look at the most common reasons for period fatigue.

Hormonal changes

Your hormones fluctuate quite a lot throughout your menstrual cycle. During a typical cycle, estrogen levels rise in the first two weeks of your cycle, and then drop sharply after ovulation. Estrogen levels stay low until your period finishes, and your cycle begins again. Some women may experience a drop in serotonin levels, which can cause feelings of low mood and fatigue.

Loss of iron

If you’re prone to low iron levels or experience heavy bleeding during your period, you may find that your iron levels dip below the optimum levels during your period. Iron is responsible for carrying oxygen around your body, so a lack of iron can make you feel a bit weak and tired.

How to combat period fatigue

Luckily, it’s not all doom and gloom! There are some easy lifestyle changes you can make to help your body fight period fatigue — and at Key, we have some solutions for you, too.

Lifestyle adjustments

These are some adjustments you can make to not only improve your overall health, but also help you stay ahead of period tiredness.

  • Get more sleep. Don’t fight against the fatigue so far! It’s okay to give yourself more rest time during your period. If you’re feeling tired, listen to your body.
  • Try to unwind and destress. You may experience mood changes before your period, which may be exacerbated if you’re feeling stressed. Find a way to unwind!
  • Give your body the fuel it needs. Try to go for whole, natural foods in order to help your body fight fatigue and avoid further hormonal disruptions.
