Get an Energy Boost From Going Outside
At least once during the workday, get out of the office. Studies show that spending time outdoors provides a boost by reducing stress hormones and lowering blood pressure. "Sunlight can also increase the body’s production of serotonin, which lifts mood and increases energy," says Teitelbaum.
In addition, "air that contains a high balance of negative ions (molecules with a negative electrical charge) may increase the body’s oxygen intake and serotonin levels," says Michael Terman, Ph.D., director of the Center for Light Treatment and Biological Rhythms at New York–Presbyterian Hospital. Negative ions are produced when there’s a lot of air and water movement in the atmosphere, like during a thunderstorm. Terman has found that when people with seasonal affective disorder (a mood disorder associated with seasonal variations of light) and depression use specialized negative-ion generators, their symptoms improve.
