A simple advice to lift your mood: Take in some sunshine; take a walk; sit under the morning sun. The effect is as simple: body "wakes" up.
Sunshine is a large,wall-mounted disk with changing lights. It "senses" the light outside and projects a glow of light outside, and must have sunshine in the room. When you feel sleepy or tired after work, the light can be opened to give out energizing light. Waving your hands back and forth in front of sunshine, just like the motions of opening curtains, changes it to energizing blue light to increase your energy levels.
Trans light is a portable version of sunlight. Trans light opens an energizing blue light whenever and wherever you need the extra boost of energy.
