Snowed in? Here’s how to beat the winter blues

“She’s seen the same cage, the same scene, the same everything, day in and day out,” Schlozman wrote. “But alas, my kid’s hamster cannot work scissors, or a remote control for the television, or engage in any sort of higher order thinking.”

But too much time for thinking in the winter can lead to trouble. Millions of Americans experience a serious mood change during the winter months, when there is less natural sunlight. The condition is called seasonal affective disorder, or SAD. According to the National Institute of Mental Health, it’s a type of depression, with symptoms such as:

  • Sad, anxious or “empty” feelings
  • Feelings of hopelessness and/or pessimism
  • Feelings of guilt, worthlessness or helplessness
  • Irritability, restlessness
  • Loss of interest or pleasure in activities you used to enjoy
  • Fatigue and decreased energy
  • Difficulty concentrating, remembering details and making decisions
  • Difficulty sleeping or oversleeping
  • Changes in weight
  • Thoughts of death or suicide

While the specific cause of SAD remains unknown, researchers have narrowed down a few factors that may come into play.

Get outside. Bundle up and take a walk, even a short one. Even on a cold or cloudy day, outdoor light can help — especially if you soak it in within the first few hours or waking up in the morning.

Make time to work out. Exercise helps decrease stress and anxiety, both of which can increase symptoms of SAD. As we all know, being more in shape can make you feel better about yourself, too, which can lift your mood.

Last but not least: socialize. When you’re feeling down, it can be hard to be social, but that’s when it’s most important to connect with those around you. So grab your spouse, your kids, a neighbor and let us see what you’re up to by posting on social media using the hashtag #CNNsnow.
