Now I do realize this would be a very small amount of blood, but I'm just curious. Yes, there are health risks associated with ingesting or being exposed to menses, because this is both fluid sharing and also blood sharing, even though menses is more than just blood.
Most over-the-counter sleep aids contain antihistamines. Tolerance to the sedative effects of antihistamines can develop quickly â so the longer you take them, the less likely they are to make you sleepy. In addition, some over-the-counter sleep aids can leave you feeling groggy and unwell the next day.
The side effect of these actions is that you feel drowsy (think of what happens when you take Benadryl). Although they're generally not as effective as prescription sleep aids, an over the counter sleep aid can help you get some much-needed rest if you used occasionally and correctly.
