I hammer most the day in north Alabama then run and work out.
Use fans in the shop. Drink water constantly ( acouple of ounces atleast every 15 min ) but do not bloat. Your urine should be clear. A lot of the drinks like gatoraide are recovery drinks. Drink them in the evening.
Cool water not cold . Cool water absorbs quicker than warm.
Hydration is a 24 hr. task.
If you do start to feel weak retreat to a cooler place and seek help if needed. Its better to loose a days work than a week with an IV stuck in your arm.
And there are days with heat factors over a 100 maybe we need to take off or work nights.
Like momma said " It makes sense."
