Hi!
The truth is that I hope that at least this will not interfere with my daily life, because right now, my ability to concentrate when I have trouble breathing is practically non-existent.
I find the methods you use to keep it at bay interesting (and hopeful).
I have bought some books about breathing, the Buteiko method and others on Amazon. I will put them into practice as soon as possible.
Regarding walking, I have noticed that if I increase my speed to more than 4 km/h (in the EU we use the decimal metric system) the problems start: my hips and knees ache, my chest get compressed, etc. (I am 55 years old and currently suffering from obesity, due to a lack of physical exercise). According to my smartwatch, I walk an average of 5,000 steps a day, but these are steps I take at home or at work. However, it seems like a very good idea to me and I think I'm going to start walking. It may take me a while to get to 10,000 steps in the long run, but I'll set it as a goal. Thank you so much!
My diet is mainly based on vegetables, legumes, whole grains and fruit, sometimes accompanied by chicken, turkey or fish and, very occasionally, eggs (it is a specific diet for people who have had a heart attack).
I will implement the "rescue" breathing exercises that you mention to help me. I thank you too.
Many thanks for everything. Now I am going to put your methods into practice and in a while, I will tell you about the results.
