Summarize this article:

Being overweight and living a sedentary lifestyle puts you at an increased risk for prostate cancer. Start a regular exercise program, even if it's just walking for 20 minutes every other day. Add resistance training to strengthen your muscles. Interval training may be a good choice if you don't have a lot of spare time to devote to training and exercise. Not having a good balance between work and play can increase stress levels, which in turn causes your body to produce more DHT. Set aside 15 or 20 minutes each day to do something that is fun for you.  Choose a restful, calming activity, such as reading a book, coloring, or working a jigsaw puzzle. You also want to make sure you're getting enough sleep. Too little sleep can also increase your stress level, leading to increased DHT levels. Stress may cause your body to convert more testosterone to DHT. A massage not only reduces overall stress, it can also stimulate and improve circulation, which can encourage hair growth. Try a massage every other week for a couple of months and see if you notice any improvement in your overall stress level. On top of the other health risks of smoking, smokers also have higher DHT levels than non-smokers. If you have elevated DHT levels and you smoke, quitting can help normalize your body's DHT production.  Because cigarette smoking increases levels of DHT and other hormones, it may cause an increased risk of prostate cancer (although some studies have shown the opposite). Smoking does increase the likelihood of death from prostate cancer. Smoking in and of itself also causes hair loss, regardless of the effect of smoking on DHT levels.

Summary:
Exercise 3 to 5 days a week. Schedule time for rest and relaxation. Get a massage to reduce stress. Quit smoking.
