Seasonal changes can affect all kinds of things in your life, but did you know that your ability to get a good night’s sleep could be under attack, too?

Changes in temperature, precipitation, atmospheric pressure, and humidity are all seasonal changes that can adversely affect your ability to sleep.

In the winter, your biggest foe comes in the form of less vitamin D. According to research, the lack of sunlight during winter months may influence our serotonin levels, leaving many individuals feeling more depressed and fatigued in the winter.

That depression and fatigue can ruin your ability to fall asleep.

So what do you need to beat the winter blues that are keeping you from getting a good night’s rest? Vitamins to help sleep are a great solution when you’re trying to avoid the groggy feeling that some sleep medications can leave you with.

How much vitamin D you need is dependent on your deficiency, so check with your doctor for a recommended dosage.
