4 Period Facts No One Has Told You Before
By SELENACARE Redaktion · 18 November 2022

The menstrual cycle tells us about our health and makes new life possible. Yet even though our period accompanies us through a large part of our lives, there are often gaps in our knowledge about it. We want to change that and share a few fascinating facts you may not have known.
1. You dream more intensely during your period
You may already have noticed yourself that we wake up more often and sleep less well during our period. A study of 944 menstruating people looked into exactly this. The result: almost half of the participants said they could remember their dreams the next day. 179 people reported having bad dreams. The reason could be the corpus luteum hormone, which is released in greater amounts after ovulation. It has a sleep-promoting effect, which is why we sleep well during this time. Shortly before your period, this progesterone level drops, the effect wears off and we suddenly start dreaming more intensely again.
2. You have up to 450 periods in a lifetime. That's around 30 litres of blood.
Especially on heavy days, it can feel as though you are losing litres of blood. In truth, it is only around 60 ml per period. That's the capacity of an espresso cup, or three shot glasses. How much blood you lose during your period naturally varies from person to person. Excessively heavy bleeding (hypermenorrhoea) means losing more than 80 millilitres of blood per period. In other words: if you need to change tampons or pads after less than 2–3 hours, or regularly struggle with iron deficiency during your period, that is a sign of hypermenorrhoea.

3. Your period costs 7,000 euros over a lifetime
How much do you spend on period products each month? Let's assume you only use disposable products and menstruate five days a month. For 40 years. That adds up to around 2,500 euros for tampons, pads and panty liners. Perhaps you also need heat patches or painkillers during the first 3 days. All of that adds up to about 7,000 euros. And that doesn't even include contraception or products for the postpartum period or bladder weakness.
Now imagine you have a heavy flow that lasts more than five days. Or you have spotting and need additional period products. It all adds up. Fortunately, there are now reusable period products that can save you money in the long run.
4. Reusable period products save 5 kilograms of waste. Every year.
Whether tampons, pads or panty liners – they all come wrapped in two or three layers of plastic. Sensible for hygiene reasons, but a disaster for the environment. Pads and panty liners themselves are made of up to 90% plastic. One pack of pads is the equivalent of four plastic bags. So in a single year, one person produces 5 kilograms of waste.
If you menstruate for 40 years, using 16,800 period products, that comes to 200 kilograms of waste. It's hardly surprising, then, that every year 75,000 to 125,000 menstrual hygiene products end up in the bin in Germany, Austria and Switzerland. For us, reducing waste is therefore not just a trend but a necessity. A great way to cut down on waste is to use washable period products such as menstrual cups or period briefs.
