Dietary, as carbs and significant amounts of protein tend to make me hotter when able I eat more salads, this is not always possible due to the fact that salad comes from outside, and sometimes my body won't chew or swallow salad. My water/fluid consumption rises, from around 3-6 liters a day to, yesterday, 11-12 liters a day.
Blinds, curtains, and windows are drawn/shut all the time. My considerate neighbours ensure this is the case due to their windows being open with music on full blast all day (presumably it needs to be that loud so they can hear it above the noise of everyone else doing the same), and from around 10PM to 5AM everyone in this and, from the sound of it, every other area, having a wild street party/punch ups/catcalling competitions immediately outside my bedroom window (to compliment the parties in neighbouring flats which means that trying to sleep in the living room is also untenable), every night!!
Not that being able to open the windows would make much of a difference, as there is never any wind here, fans also don't help, I used to have several fitted but all they did was make me cook faster.
I also find that increasing the amount of washing (clothes/bedding etc.) and drying/changing etc., along with increasing the amount of washing (personal) helpful in dealing with the heat.
My cat also helps me deal with the heat, apparently food goes bad within 10 minutes of being put out, but must be at room temperature, but not the temperature of any room in my home, as they are all 30C plus, all the time, (so fridging it is not acceptable), or else it is inedible and she will refuse to eat, for days, until she is so ill she can't stand, after having gone through a helpful phase of throwing up for a few days. Because of this she feels the need for constant reassurance and my allocated time for paying attention to her rises from a few minutes a day to several 20 minute long sessions, during which I have to go to her, get down on the floor, as she simply can't be arsed to come to me and will just sit yelling at me to please put her out of her misery.
Obviously I retaliate, at least once a week meat is cooked for her, of varying types depending on her taste at that moment, so that's 2-3 hours with the oven on, followed by washing up, and subsequent cutting off small bits, followed by more washing up and hoovering, as apparently cat's hate plates, and large feeding trays, carpet is the only place cats will eat from, which is puzzling, why don't all the tigers starve, or is this why they are going extinct? It should be noted that I generally don't get any of this meat, it's done for the cat, I can't be bothered with eating it. let alone preparing veg to go with it after cooking it. It's done for the cat as, if she's not eating much cat food, and cat snacks make her ill these days, she has to have something, and apparently a good kicking is now illegal, as it might make her unhappy, and making, or permitting a cat to be, unhappy is currently against the law in the UK.
I find the constant traipsing up and down the stairs to get rid of all the waste cat food and meat, which the heat makes stink so much more, and faster, than normal, particularly helpful in dealing with the heat, as it's both cooler out there and, combined with the washing, the cat related duties, the diet of 46 calories a day (when able), the 30 minutes of sleep a night, and all the extra washing, makes me virtually unconscious a lot of the time, ...........
..........so I simply don't notice the heat.
