From the Menstrual Period to Ovulation (the details you may not know!) When your menstrual cycle begins, your estrogen levels are low. Your hypothalamus (which is in charge of maintaining your hormone levels) sends out a message to your pituitary gland which then sends out the follicle stimulating hormone (FSH).
Medical Definition of SEASICKNESS. : motion sickness experienced on the waterâcalled also mal de mer.
Seasickness may hit one person hard, while others donât feel a thing. So whatâs the deal? âThereâs no way to prevent motion sickness 100 percent,â says Dr. Art Diskin, Royal Caribbean Cruises Ltd. Global Chief Medical Officer. But will it ruin your cruise? Not likely. âMost new cruisers have no problems with seasickness on our ships, due to their size, navigational avoidance of storms, and stabilizers,â he explains. Before we get to the specifics, a breakdown: Motion sickness occurs when what you see conflicts with what your inner ear senses. In other words, if youâre sitting in a car (not moving) but your inner ear detects movement (the car just hit 70 mph on the highway), the two signals being sent to your brain donât match. Those mixed signals confuse the brain, and the resulting sensations and symptoms (dizziness, nausea) are the result.
