This kind of heat reaction happens to me even with the many sun protection measures that I take, which I know are common for my fellow autoimmune friends. I have developed a pretty reliable playbook:
1. SPF 30 or above sunblock
2. The big floppy UPF protected hat,
3. Big sunglasses with UV protection.
4. Staying in during peak sun hours
5. Keeping my arms and legs covered.
It's a short list, but easier said then done. The last one, dressing like it's October, in particular can be annoying when it's already 90 degrees and wearing even light long sleeves can just add to feeling hot. Staying inside except for later in the evenings has been the only strategy that is full-proof but it is difficult in practice and leaves me feeling a bit antsy. Who wants to have to stay inside during the summer months? I love the summer. I have to do enough of the hibernation during the winter.
So, for obvious reasons I've been looking for a strategy to be outside during heat--if only for short periods of time so I can do at least do a few errands. I've finally come up with something that helps. It's a radical new invention: an umbrella!
Of course, I've sat under umbrellas at a pool or on a vacation at the beach, but I had never thought of holding one just walking around in my neighborhood. I suppose this is what aristocratic women used to do to protect their skin in pre-sunblock days so I'm in good company. I'm not sure why ladies' umbrellas went out of fashion but I'm told they are still very popular in China. Even intuitively it make sense that an umbrella is more effective than a hat in almost every respect. I've found some compact umbrellas online with UPF protection that should work well both rain or shine.
