I’m fairly new to training, just starting in on my second time going through base and build. I have noticed that the day after I workout in the heat (80° f or higher) I usually wake up with a headache.
I assume this is dehydration, but I feel I am drinking enough water. I try to drink water all day, usually around 80oz. I drink water every 10-15 min when on the trainer, and drink like 40oz after the workout is over.
What am I missing? Is this a common issue? I am in sweet spot base low volume, workouts are only 60-90min so nothing crazy. On the podcast they talk about mixes and salt tablets but that seems to be geared towards much longer efforts like xcm or long triathlon so I kinda assumed my issue was something way more simplistic. Gatorade seems to help but don’t like all the extra sugar.
