Being depressed can make you feel helpless. Along with therapy and sometimes medication, there's a lot you can do on your own to fight back. Changing your behavior -- your physical activity, lifestyle, and even your way of thinking -- are all natural depression treatments. Do you want to learn natural depression treatments that can help you feel better -- starting right now? Here are some tips. 1. Get in a routine: If you’re depressed, you need a routine, says Ian Cook, MD, a psychiatrist and director of the Depression Research and Clinic Program at UCLA. Depression can strip away the structure from your life. One day melts into the next. Setting a gentle daily schedule can help you get back on track. 2. Set goals: When you're depressed, you may feel like you can't accomplish anything. That makes you feel worse about yourself. To push back, set daily goals for yourself. "Start very small," says Cook. "Make your goal something that you can succeed at, like doing the dishes every other day." As you start to feel better, you can add more challenging daily goals. 3. Exercise: Exercise temporarily boosts feel-good chemicals called endorphins. It may also have long-term benefits for people with depression. Regular physical activity seems to encourage the brain to rewire itself in positive ways, Cook says. How much exercise do you need? You don’t need to run marathons to get a benefit. Just walking a few times a week can help. 4. Eat healthy: There is no magic diet that fixes depression, but watching what you eat is a good idea. If depression tends to make you overeat, getting in control of your eating will help you feel better. Although nothing is definitive, Cook says there's evidence that foods with omega-3 fatty acids -- such as salmon and tuna -- and folic acid -- such as spinach and avocado -- could help ease depression. 5. Get enough sleep: Depression can make it hard to get enough sleep, and not getting enough sleep can make depression worse. What can you do? Start by making some changes to your lifestyle. Go to bed and get up at the same time every day. Try not to nap. Take all the distractions out of your bedroom -- no computer and no TV. In time, you may find your sleep improves. 6. Take on responsibilities: When you’re depressed, you may want to pull back from life and give up your responsibilities at home and at work. Don't. Staying involved and having daily responsibilities can work as a natural depression treatment. They ground you and give you a sense of accomplishment. If you're not up to full-time school or work, that’s fine. Think about part-time. If that seems like too much, consider volunteer work. 7. Challenge negative thoughts: In your fight against depression, a lot of the work is mental -- changing how you think. When you're depressed, you leap to the worst possible conclusions. The next time you're feeling terrible about yourself, use logic as a natural depression treatment. You might feel like no one likes you, but is there real evidence for that? You might feel like the most worthless person on the planet, but is that really likely? It takes practice, but in time you can beat back those negative thoughts before they get out of control. 8. Check with your doctor before using supplements: "There's promising evidence for certain supplements for depression," says Cook, such as fish oil, folic acid, and SAMe. However, more research needs to be done before we'll know for sure. Always check with your doctor before starting any supplement, especially if you’re already taking medications. 9. Do something new: When you’re depressed, you’re in a rut. Push yourself to do something different. Go to a museum. Pick up a used book and read it on a park bench. Volunteer at a soup kitchen. Take a language class. "When we challenge ourselves to do something different, there are chemical changes in the brain," says Cook. "Trying something new alters the levels of dopamine, which is associated with pleasure, enjoyment, and learning." 10. Try to have fun: If you’re depressed, make time for things you enjoy. What if nothing seems fun anymore? "That's just a symptom of depression," says Cook. You have to keep trying anyway. 11. As strange as it might sound, you have to work at having fun: Plan things you used to enjoy, even if they feel like a chore. Keep going to the movies. Keep going out with friends for dinner. 12. When you're depressed, you can lose the knack for enjoying life, Cook tells WebMD. You have to relearn how to do it. In time, fun things really will feel fun again.
