Quite a few corrective measures can be taken for too much energy in the head...
1) GROUNDING EXERCISES
One good example is imagining a deep crimson triangle in the base of the pelvis (pointing down) and imagining it sprouting cool, strong roots that descend through the legs, through the K1/bubbling spring points of the feet and penetrating deep into the ground down to the cool center of the Earth.
Another grounding exercise is to "spiral" your energy into your lower dan tien. If male: Circle your hands in front of your navel, palms facing your stomach, in the direction of the bowel movements of the large intestine. If female, "spiral" in the opposite direction.
2) WATER MEDITATION
Concentrate on the Sahasrara chakra as a source of pure, soothing light and energy. Imagine that energy pouring down as a pure, cold source of the purest blessed water that pours into your baihui point (GB20/Gall Bladder-20) and descends/pours down the front of your face. A key element is touching the tongue to the roof of the mouth. Feel around with the tip of your tongue for the location that feels the most "energetic" and lightly touch it while you feel for the charge of energy running down the front of your body (this is the way to connect the governing and conception vessel to complete the microcosmic orbit). Visualize this pour of cool water down through this channel and into your lower dan tien. Use each inhale as an opportunity to breath this cool energy into your diaphragm and into your lower dan tien.
