45-year-old woman feeling tired all the time? What women keep quiet about, and shouldn't
A 45-year-old woman feeling tired all the time often blames her character: "I've gotten lazy," "everything irritates me," "it's just age." But behind it there are often nights: lighter sleep, waking up, heat under the covers, things women rarely mention even to their doctor. Here's what's going on, what's worth checking and where to start.
"It's like I've forgotten how to rest." "I used to get everything done, and now I'm out of energy by lunch." "I've gotten so irritable, I guess my personality has changed." Women over 45 say these things to friends, to themselves, sometimes to their husbands. To their doctor, far less often.
The uncomfortable truth: it's often not about personality or laziness, but about nights. And women keep quiet precisely because it seems that "everyone goes through this, it's just how it is."
Why am I so tired in my 40s, especially after 45?
Largely because of sleep: the hormonal transition makes it lighter and more broken. According to Stanford University, 40–60% of women in perimenopause and menopause have sleep problems.
One reason is falling progesterone: Stanford links it to trouble falling asleep, lighter sleep and waking up at night. And the Sleep Foundation notes that women in perimenopause wake up more often at night and lie awake longer than women their age who aren't in this stage. You can spend the same eight hours in bed and still feel less rested.
Perimenopause fatigue: how are they connected?
Through nights you don't always remember. Brief awakenings are forgotten by morning, but the tiredness stays.
According to a survey by the AASM, the leading U.S. professional society of sleep specialists, among women aged 45–64 37% often wake up during the night, and for 35% hot flashes or night sweats disrupt sleep. During the day, this turns into what the Sleep Foundation describes as daytime fatigue, trouble concentrating and mood swings.
