How long does it take to get heat stroke?

It's been so hot lately, and I worry about my grandparents being out in the sun. I was thinking, if someone is exposed to extreme heat, how long does it usually take for them to get heat stroke?

If you are out in direct, extreme sun during peak North Indian summers, it can happen in just 30 to 45 minutes of heavy exertion. Please stay hydrated and try not to step out without an umbrella or cap, the heat is really scary these days.

Heat stroke can develop in less than an hour if your body temperature rises rapidly without sweat evaporation. It is a medical emergency, so if someone is dizzy, confused, or has hot dry skin, please take them to a doctor immediately.

I had a severe case of heat exhaustion last summer and it was terrifying how fast I went from fine to completely fainting. It took less than an hour of walking in the sun. Please listen to your body and stop if you feel weak.

My 10-year-old son fell very sick after playing outside in the May afternoon heat for just 40 minutes. Now I never let him play in the open during peak sun hours, and always make him drink lemon water or ORS before going out.

Honestly, standing in the afternoon traffic for just 20 minutes makes me feel like I am going to melt. It doesn't take long to get heat illness, so please carry a water bottle and avoid long outdoor walks in the afternoon.
