Myth 1: You’re more likely to be attacked by an animal

There’s a rumour floating around that you are more likely to be attacked by sharks whilst on your period and, even more bizarrely, that brown bears are attracted to the scent of period blood. Sounds a little silly, right? 

Well, to clear up these issues once and for all, research has actually been conducted. Yellowstone National Park analysed all bear attacks on their grounds to ascertain whether menstruation had any influence. They found, rather unsurprisingly, that most attacks on women occurred by accident when the individual came across a bear whilst hiking. So, their conclusion was that no link could be drawn between the females attacked at Yellowstone and menstruation.1 Phew!

So, what about sharks? Well, if you’re heading off to Australia any time soon you really needn’t worry about venturing into the sea…

The amount of blood you pass during the course of your period is miniscule, especially if that blood is then dispersed into the sea. This means a shark would have to be right next to you in order to detect it. Not convinced? Just think of this – the Great White Shark can detect one drop of blood in about 100 litres of water. That is about 1/25,000th of what’s in an Olympic-sized swimming pool! If sharks were able to detect every drop of blood in the ocean they’d be quickly overwhelmed!2  

So, sharks and bears, it would seem, do not pose an increased threat to women when they are on their period.

Myth 2: You can’t swim or bathe

Talking about swimming, one of the most common misconceptions young girls have when they start their period is that they won’t be able to swim or have a bath. Ok, so most of us know this one simply isn’t true.

From the moon cup to good old fashioned tampons, there are a variety of menstrual products that enable us to swim comfortably whilst on our periods. As for baths, well these can actually help to ease period cramps so are a bit of a savior when it’s your time of the month. 

This particular myth however, may have started out as fact. Although tampons were available before the 1970s, maxi pads were not and as a result many women relied upon a sanitary belt during their period. This wrapped around the waist and had clips at the front and back to hold a piece of cotton in place. This doesn’t sound very comfortable for day-to-day wear but it was even less conducive to water-based activities. 

Therefore, a lack of menstrual products in times gone by made swimming and bathing difficult. However, fortunately menstrual products have advanced significantly since the days of the menstrual belt and now it is safe to say if you want to head to the pool or dig out the bubble bath when you are on your period, go ahead!

Myth 3: People can tell when you’re menstruating

This is another worry faced by girls at the start of their period journey – what if their classmates can tell they’re on their period? What if people stare?

Well, yet again this is a good old myth. Menstrual products are now so discreet that you can run, jump, skateboard, dance, even fly and no one would have a clue that you were on your period.

However, spare a thought for the women who had to deal with periods before the introduction of menstrual pads. Many complained that the bulky sanitary belt could be seen through their clothes!

Myth 4: Periods can sync

This is a phenomenon that’s been given a lot of attention over the years, so much so that I dedicated a whole blog to the topic. However, although it’s a nice idea that your own period and that of your friends and sisters could synchronize just because you spend lots of time together, it’s more likely to be down to chance.

Also, I’m sorry to disappoint you but stress, exercise, diet and sleep all influence your period. Therefore, a change in any one of these things could alter the time of month in which your period hits so that it begins to run in time with those around you.

Myth 5: Cold drinks will make cramp worse

Although there is some anecdotal evidence to suggest that cold drinks may make period cramps worse, there’s little hard science surrounding the issue. As a result, I would suggest that a cold glass of orange juice or a refreshing glass of water is pretty safe at this time. 

That being said, there are a number of cold drinks you should try to stay clear of during your period. Alcohol for example, dehydrates you which can make symptoms like cravings and fatigue more pronounced. Also, sugar-filled drinks like Coca-Cola and lemonade can cause energy levels to spike rapidly and then decline thus making you feel lethargic. We know fatigue is a big problem for women on their periods so it’s best not to make the problem worse by fuelling up on your favourite soda!

Myth 6: Exercise on your period is bad for you

Should your period give you an excuse to ditch those trainers for a pair of fluffy slippers?  

Well, no, unfortunately it does not. I know this is not what you wanted to hear (unless you absolutely love exercise of course) but provided you don’t do too much, exercise can actually help to ease period symptoms. Cramp for example, can be made worse when there’s a lack of blood flow to the stomach area but as exercise increases blood flow around the body, this means it can work to reduce the prominence of cramps. 

Fast runs or energetic hikes are probably not the best idea on your period but take as many long walks and exercise classes as you like! 

Myth 7: Very heavy periods are normal

Finally, this is the biggest myth of all. 

Periods are a very individual thing with the severity of symptoms differing from one woman to the next. This means that not only is it difficult to compare periods, it’s also impossible to claim that that very heavy periods are normal! 

Not only that though, it’s quite risky to state that very heavy periods are normal. A particularly heavy period could indicate that something else is a play like an underlying condition or a hormone imbalance. Plus, a heavy flow is extremely bad for women’s health in general as it causes problems like anemia, light headedness and fatigue.

So, how do you know if your period is heavy? 

  • Regular leakages
  • Having to use more than one sanitary product at the same time
  • Having to change your sanitary product every hour or so
  • Losing lots of blood (the average woman loses six to eight teaspoons of blood during the course of her period)
  • Cramp that interrupts your day-to-day life


Therefore, if any of these things apply to you then it’s time to see your doctor to find out what’s going on because a very heavy period definitely isn’t normal!

If you experience heavy periods alongside symptoms such as irritability, severe cramp, mood swings and bloating, once you’ve got the ok from your doctor you may find it helpful to try Agnus castus. These symptoms are associated with too much oestrogen and too little progesterone which this herb helps to balance out.
