I meditate. I'd recommend it for anyone. If it sounds cooky, give Dan Harris's review a try. I'll post a link below. It's really simple and just trains your brain to turn off your brain and teaches you to be present in the moment and not contemplate the million scenarios that could play out, while focusing on what you want.
There are many factors that have the ability to improve your health and help you better handle stress. Reducing screen time, exercise, diet, and sleep and some of the biggies. For me, I try to limit my screen time in the evenings and generally put the computer away after 8:30pm, which is soon so I better go! Also, I get my 8 hrs of sleep every night, I follow a fairly regular meal plan 6 days a week, I get in a good workout 6 days a week, and I meditate for 10-15 minutes every evening. It's hard to say which are the most important.
Nothing else matters if I can't sleep. Meditation helps me to be able to be at ease and sleep well. Once that's in check lifting is the best stress reliever for me and nutrition just keeps things moving in the right direction and makes you happy with you look and feel. But, the reality life is stressful and that's OK. Work, relationships, money, etc. can all be stressful. The key IMO is to accept it, realize your situation is not permanent, take steps to improve, and be satisfied with your steps in the right direction.
