Meditation focuses your thoughts and helps prevent overthinking and rumination on multiple topics. Because such rumination often exacerbates depression, stress, and anxiety, meditation helps combat these mental states. Meditation practices can also be applied at night if you have trouble sleeping and find your thoughts racing. Some studies have also shown that mediation improves the immune system. Successful meditation lowers the blood pressure and pulse rate, while stress hormones drop and brainwaves resemble the early stages of sleep. Meditation is not as easy as it sounds and requires practice. However it gives you tools that can be applied on a daily basis.
