Why do I get tired with heat?

It's like any time I use heat, I'm instantly tired. Every time I step outside in the summer (I live in CA), sleepy. Every time I use a heat pad to treat an injury, I'm sleepy. If I'm really warm in my blanket, I'm sleepy. I just wonder why this is.

    Heat exhaustion is often due to enervation caused by too much heat and too much dehydration.

    In a hot environment you need to drink more water than normal to prevent dehydration.
