Get Light Exposure. Light stimulates dopamine production which increases energy, motivation & productivity. Lack of light causes winter blues & tiredness. Unfortunately home/office lights aren’t bright enough. You need sunlight.
Open Window Blinds. This gets you sunlight exposure when you wake up and during the day. If you work in an office: open the window blinds and place your desk so your eyes get sunlight exposure.
Walk Outside. A 30 min walk in the morning sunlight will stimulate the production of dopamine. Do not wear sunglasses: UV is low at sunset. Your eyes will be safe unless you look directly into the sun.
Use a Sun Box. If your place doesn’t have big windows to let sunlight in or if it’s winter/cloudy or if you can’t get outside in the morning, then use a light box like this one for 30mins after you wake up.
