From November to March, about 20-percent of the population suffers from Seasonal Affective Disorder or SAD.
SAD is a serious mood change during the late fall and winter months when the weather gets cold and the days get shorter and you just want to sit at home and not be productive.
Health experts say those people can easily slip into depression, and that is why the best thing you can do is to be active and busy.
Be sure to get at least eight hours of sleep, eat a balanced diet, and exercise.
"Seeing other people, being social, it's a time you don't want to because of the weather being cold. Getting out and being social and doing things like things in your community or your church, just going shopping. Just taking better care of yourself so you're not isolating," said Sandra Ford R.N. of Mark Twain Behavioral Health.
Ford also says the best thing to do is to go outside to absorb sunlight for about 5 to 10 minutes when you can during the day.
There are even full spectrum light bulbs available that you can use to put around your home to help give you that light during the evening hours.
