During the post-ovulation phase and before the phase (called the luteal phase), many women have reported having trouble sleeping, from insomnia to frequent waking up to nightmares. This is especially common in women with premenstrual dysphoria (PMDD), a more severe type of premenstrual syndrome, according to the U.S. Department of Health.
While sleep quality can improve early on in your period, other more common period symptoms like gas, weight gain, and brain fog can occur – all of which could only be exacerbated by this lack of sleep, explains Cabeca.
Think About It: Poor sleep affects bowel health, which can lead to the ever-dreaded gas, gas, gas, and diarrhea that all too often coincide with your period. And if your period is making you foggy or forgetful, it could be the hormones, but it could also partially cause you to miss sleep.
