Men have thicker bones and tend to not have as much degradation of the bone because they don't have estrogen, progesterone perturbations that are changing the signaling to progesterone.

increasing bone density or stopping the growth of bone right so women have this perturbation throughout their menstrual cycle that will change how their bones are responding and then when we don't have a menstrual cycle or we get put on an oral contraceptive pill we have changes in that signaling which changes our bone density and you mentioned sleep a second ago yeah how is sleep relevant and what's the variance between men and women as it relates to sleep

Sleep's really important because that's where we have our parasympathetic drive and our ability to recover. So the whole, I shouldn't say the whole reason, because nobody really knows why we need to sleep other than the fact this is where our physical and our mental capacities become solidified.

So that means that our body fully repairs while we're sleeping, our memories get solidified, our brain becomes a little bit relaxed and can repair itself while we're sleeping. For women, we see changes across the menstrual cycle in our sleep phases. So when we are slow sleep phases, meaning our deep sleep versus our late sleep versus our dream sleep.

For women, we see changes across the menstrual cycle in our sleep phases. So when we are slow sleep phases, meaning our deep sleep versus our late sleep versus our dream sleep.

And we need to get in that really super deep sleep in order to have optimal reparation. When we are getting close to the bleed phase, then we see more interruption in the sleep. And it's really, really apparent for women who have really bad PMS or other conditions that happen to affect estrogen and progesterone. We have an increase in our core temperature from progesterone.

We have changes in melatonin pulse because of estrogen. So when women are talking about having really poor sleep right before their menstrual cycle, it is because we have these sex hormones that are interfering with our sleep phases. For men, they don't have that perturbation. For men, we see that chronologically they tend to have a melatonin peak that's later than women.

So they tend to want to stay up later and they can sleep in, but they can also have shorter sleeps. So there's a chronobiology aspect that comes to it with regards to how our body actually falls asleep and wakes up. And there's a sex difference in that chronobiology.

Women suffer more with jet lag.

Because if we're looking at our circadian rhythms and how long they are, like I said, melatonin peaks earlier for women than men. And we have a slightly different... What does that mean? Sorry, melatonin. So melatonin is what allows our body to actually get into sleep. And our wind down for that is melatonin production. Okay.

So a lot of people will start to feel really sleepy at like 4 in the afternoon. It's just a natural occurrence. Our core temperature comes up. We start to have melatonin production. And for women, a melatonin peak for sleep onset hits around 9 p.m. on average. For men, it's about 10 or 11 p.m. because our circadian rhythms are different. So women are on a shorter side than men.
