Yard work like mowing grass is one of the things I find that I don't adequately hydrate during. If you wait till afterward to hydrate it's too late. You might be tired for days. IMO. electrolytes and carbs play a part too, but mostly it's just keeping water in you.
I've got to ride 30 plus today and then come home and walk behind a mower for 70 minutes. On the bike it's easy to take a gulp every 10 minutes since there are two bottles in the main triangle. Maybe I need to install some bottle cages on the mower!
If you're doing yardwork in high heat you could try a small Camelbak. I usually put a water bottle out near me so I don't have to go inside to get a drink. Or I guzzle before and make myself take water breaks during yardwork.
When the weather gets hot I seem to be in a constant state of dehydration from riding and just being hot.
