Oh and you mentioned a bit ago how you find the heat invigorating in small doses, and I can actually explain the science behind that. The amount of energy you feel like you have at any one point in time is the result of a lot of different factors, but one of the key ones is your heart rate. As a general rule the faster it's beating the more blood flow you have and so the more "aroused" your brain is (arousal in exercise science terms simply meaning how ready your brain is to perform a task). When your body heats up it tries to cool itself off, and the first few steps in that process involve your blood vessels dilating and your heart rate increasing so that more blood is pumped away from your organs and towards your extremities. This carries heat outwards to your skin so it can radiate off or your sweat can evaporate it away. That increased heart rate and blood flow loosens up your muscles (the heat directly helps with that too) and wakes your brain up by delivering more oxygen and nutrients to it. It's the exact same effect you get by going into a sauna before working out. The reason this is a short lived effect though is because as your body temperature rises faster than it can cool itself off that causes the chemical reactions in your cells to become less efficient. Biochemistry essentially depends on molecule A floating around inside the fluid medium within your cells (the cytosol) until it bumps into molecule B (usually an enzyme) and causes a reaction. When you heat liquids up they expand which reduces the density of anything suspended within them and thus decreases the frequency of A bumping into B, which slows down the rate of reactions. The molecules within the liquid do move faster when hotter, but that doesn't really compensate for the decreased frequency of the reactions. On top of that stuff like amino acids and enzymes are carefully folded into specific shapes to do what they do, and when you heat them up they start to unfold and stop working as well. So that's why it sucks to be in the heat for a while but feels good for a little bit.
