The widget below matches the wavelength of light (in nanometers) to a particular color of light. Explore by entering various values between 400 nanometers and 700 nanometers. Values outside this range are not visible and therefore not associated with human-perceived color.
Researchers have documented the benefits of a regular practice of simple, deep breathing (1,2,6), which include: 1  Reduced anxiety and depression. 2  Lower/stabilized blood pressure. 3  Increased energy levels.  Muscle 1  relaxation. Decreased feelings of stress and overwhelm.
Breathing exercises can lower your heart rate. A high heart rate could be the result of stress or anxiety. When you are under duress, your body releases a chemical called adrenaline as part of the âfight or flightâ response. Adrenaline increases your breathing and heart rates in an effort to help you deal with the cause of the stress.
