Make sure you use a long extension cord to a fuse without RCD for the hair dryer, though - otherwise the constant resetting of the breaker will eat up all your time savings.
Well, I have been doing this for a couple of years now. I brush my teeth before eating in the morning because apparently that's better for your teeth, otherwise you might damage enamel. Or you wait for at least 30-60 minutes, but nobody's got time for that. Just rinsing with water after eating is fine.
Truth is I usually don't eat breakfast, so I don't have to think about it. But when I do, it's this order for me now.
I don't see how brushing your teeth in the shower saves time. Unless your brushing while you shampoo or something, you're just making your shower longer, which wastes more water.
It's a habit I picked up in basic training. We had 50 girls to 12 shower heads, and we really didn't get much time for all of us to shower at all in the first couple weeks (the time constraint was relaxed after a bit though)
The tooth brushing deal though I think was because our TI would find the tiniest speck of water in the sinks after lights out and absolutely lose his shit. So we only used the sinks to wash our hands, so we didn't accidentally leave toothpaste in the bowl of the sink and miss it while cleaning up for the evening.
Either way, it's just a habit that's stuck with me through the years.
Lil flippy knob at the top of the shower head to pause the water is a great water saver. You only really need the water running for like 20% of your time in the shower. I love brushing my teeth in the shower, you can get toothpaste everywhere and then just rinse it off without making a huge mess at the sink, way easier to rinse your mouth with water angled down from above than from a sink below.
I get cold just thinking about this. Turning off the shower is my least favourite part of showering. Why repeat the experience several times in one session?
I tried this. Turns out that sonicare toothbrushes are only water resistant and will fail eventually when used in the shower every day. 0/10 Don't recommend.
Otherwise, if you spend a lot of time daydreaming in the shower to begin with, this can save a few minutes.
I'm surprised some tech company hasn't put waterproof touchscreen devices in their employee locker room showers so that their employees can reply to email in there.
