Third extended heat wave within 6 weeks.
The previous one exceeded 40°C, and the buildings not yet had time to completely cool down from that one before the third wave hit.
I was considering putting up a tent in my garden myself, but as I own a ground floor flat, the indoor temperatures did, with the help of some additional cooling measures, thankfully not exceeded 27°C.
Some nights, I’m seriously considering sleeping in the hammock on my balcony. The only problem is that the sun would wake me up (and probably roast me) way before my alarm clock.
I did this when I was visiting Mexico. Probably some of the best sleep I’ve had in my life. Balcony was on the North side of the building. Even though it was hot outside, the extra airflow through the hammock kept me pretty cool.
I sometimes do sleep in a tent outside in the garden (Not out of heat reasons yet, but because of fun events with the kids).
I wouldn’t worry about being woken up by the sun, as what will actually wake you is not the sun, but the relentlessly enthusiastic birds chirping away at the top of their lungs almost an hour before sunrise already ;-)
I used to keep a loaded nerf pistol with me for this exact reason.
Seems useless, you’d need to be awake to take the shot.
I recommend an automatic “Bird Banger” to scare them away periodically.
I doubt the birds would wake me. I sleep with my window open anyway so I’m used to them.
You might want to try a sleeping mask
I just woke up. I’m not even up. My body just woke up to go poop, then it’s back to bed.
I read “sleeping mask”, but my brain interpreted that, and imagined a gas mask. Filling the inside of the mask with sleeping gas.
I doubt that helps much when the sun shines directly on my face. I’m more worried about the heat than the light.
