According to the National Institute of Mental Health, depressive disorders affect approximately 18.8 million American adults, or about 9.5 percent of the U.S. population age 18 and older, in a given year. Even those who don't have a clinical illness may feel sad at some points in their lives.
For those who need a quick boost, there are ways to improve mood that are easy.
1. Get organized. Tackling small goals, even just tidying up the kitchen or making the bed, can have a positive effect on your mood.
2. Eat spicy food. Researchers at the State University of New York at Buffalo say that the capsaicin in hot peppers triggers your brain to release endorphins.
3. Get more sleep. Getting seven to eight hours of sleep is essential to mental health. Just being shy a few hours of rest can put you in a foul mood.
4. Be nice to others. Smiling at someone and getting a response can improve mood.
5. Exercise. Get the heart pumping and you'll feel re-energized.
