I went out this morning around 10 a.m. to ride my bike. Yes, I live in Texas, and yes it's hot. I'm used to that and it doesn't really bother me that much anymore.
I got to the end of the trail and started to come back and began to get very sick. At one point I almost passed out. When I finally got home, I could barely breathe.
Guess I was having a reaction to the heat.
I was only out there one hour, which is about usual for me. But usually I go in the evenings. It is much hotter at that time of day, but the sun is not shining directly in my face as it was on my return trip today.
I have a horrible headache now.
So, to everyone who needs to leave the house today, be sure to take water with you (I forgot mine today) and take breaks--even if you're out there for only a short time!
