Premenstrual insomnia is often caused by premenstrual tension syndrome, which not only causes insomnia, but may also cause mood changes, anxiety or situation sensitivity. It is recommended to take vitamin B1 orally or at the same time with glutamine, which has the effect of nourishing the nerves and improving sleep. In addition, it is recommended that when insomnia occurs before menstruation, appropriate dietary improvements should be given, do not eat sour and spicy, stimulating food, and do not eat too hot and dry food, such as fried food, which may aggravate the insomnia state. It is also recommended to soak your feet in hot water and drink a cup of hot milk before going to bed to help you sleep.
