    Here are my favorite tips for staying physically, mentally and emotionally healthy during the winter months. Vacation not included. 1.

Raise your vitamin D levels naturally (without pills or sunlight). We’ve all heard about the marvels of vitamin D: heart health, skin health, immune health, mental health… But you don’t need to take pills or risk skin cancer to get high vitamin D levels. The big secret is that vitamin D levels are associated with healthy lifestyle changes. For example, if you lose just 5 percent or more of your body weight, your vitamin D blood levels will shoot up. Vitamin D likes to stay in fatty tissue, so when you lose fat, the vitamin D levels in your blood go up. 2.. And when you eat your wild salmon, bake it rather than fry it. Other good food sources are trout, mushrooms and egg yolks, and my favorite, plain Greek yogurt.

3. Winter can be a tough time for many of us. All that darkness can take its toll on our mental health. The winter months can be very isolating for many people. My suggestion is that you and a close friend sign up for yoga, cooking or sewing class. 4.

Eat more plants—the ones that are sources of omega-3 fatty acids. According to the famous Harvard Nurses’ Health Study, there was no relation between depression and intake of omega-3 fatty acids from fish, 5.. And again, the wintertime is when many people have a higher risk of depression.
