How does breathing change during exercise

Your breath increases the need for both food and oxygen in the body. This is why your pulse rate and breathing rate increase with exercise. Your heart speeds up to pump extra food and oxygen to your muscles, breathing speeds up to get more oxygen and to get rid of more carbon dioxide.

10/10 recommend bring pads/tampons with you no matter what. im 16 & i’ve had mine since i was 12 and they’re still it regular, but id suggest using the glow app, many women use it for fertility reasons but i use mine specifically for the period tracking portion and it guesses when your next period will most likely be for the next two months. i dont believe theres any way to delay your period, so id say hope for the best but make sure to bring all of your stuff just incase. have a good cruise!
