Serotonin is a Monoamine neurotransmitter that is found in the gastrointestinal (GI) tract, platelets, and in the central nervous system. Studies have shown that serotonin affects our level of happiness, which is why antidepressants are used to treat conditions such as depression, generalized anxiety disorder and social phobia. Monoamine oxidase inhibitors (MAOI) prevent the breakdown of monoamine neurotransmitters (including serotonin), and therefore increase concentrations of the neurotransmitter in the brain. Here are some suggestions to better cope with Winter Blues naturally by increasing serotonin levels as explained in this article:

1. Self-induced changes in mood. This can include psychotherapy, meditation, yoga and relaxation. Ask yourself what makes you feel better, and pursue that activity.
2. Exposure to bright light. This can include walking outside in the middle of the day, or other outdoor activities like running, hiking, biking, snow shoeing, skiing, playing outdoor sports, etc. As shown in the previous post, a light therapy box can be helpful as well.
3. Exercise and movement. We tend to be less active during the winter months. For me, I try to take a walk in the middle of the day for 15 minutes or more. For others joining a gym is a great option. Exercise contributes to better sleep and lowered stress levels.
4. Diet. It is important to nourish our bodies with vitamin filled fruits, vegetables, legumes, protein and grains. It can be helpful to limit intake of sweets during the winter months, which can be challenging because of holiday traditions.
