It’s that time of year again. The sun is setting at 4 p.m., it’s cold outside, you’re craving comfort food, and you find yourself exhausted despite getting enough sleep. What gives? What causes winter fatigue?
Your body is designed to adapt to its environment. Simply put, shorter days, less sunlight, and colder temperatures switch our bodies into a different gear.
What Less Daylight Means to Your Body
Let’s start with shorter days. Your body has an internal clock called your circadian rhythm. It’s system that regulates the release melatonin, a hormone that makes you tired, and cortisol, a hormone that makes you feel more awake. Your body does its best to sync your circadian rhythm to the hours of sunlight you experience, but can be thrown off by individual habits like the tendency to stay up late. Since you’re exposed to less light, your body interprets that by telling you to go to sleep, which makes sense.
Sunlight doesn’t just affect your circadian rhythm, it also affects the production of serotonin, one of the neurotransmitters that makes you feel happy and awake, and ATP, your body’s form of cellular energy. Reduced sun exposure means our bodies are producing less vitamin D, which alters the production of these chemicals and makes you feel less energetic.
Lastly, colder temperatures put your body into something similar to a hibernation mode. You have less serotonin and your body is colder, making you hungrier and more likely to seek out high-calorie foods. Lower body temperatures also slow down your metabolism, making you more tired.
For some people, the combination of these factors can cause Seasonal Affective Disorder, a type of depression affected by the changes of seasons, with most people experiencing depressive symptoms in the winter. It can cause fatigue, trouble concentrating, increased appetite, and irritability, among other symptoms.
So how can we combat all of these processes to feel more energetic in the winter months?
How to Fight Winter Fatigue
Since you have less access to fresh fruit and veggies in the winter, which is where we get most of our key nutrients, it’s possible you’re deficient in a vitamin or mineral and that is causing your lack of energy. You can combat winter fatigue by upping your intake of certain vitamins and minerals like:
- B vitamins are implicated in energy production and deficiencies can lead to issues in creating cellular energy (ATP) for your body’s tissues to operate properly.
- Vitamin D is the most common culprit for energy problems in the winter, and supplementing with vitamin D can help you reach the daily minimum levels, which many people do not get from their diet when sunshine is lacking.
- Iron is an important component of your blood and a iron deficiency can compromise your blood’s ability to deliver nutrients and oxygen to your tissues, making you feel tired and weak.
- Magnesium supplementation has been shown to improve sleep quality and may reduce symptoms of depression through its effects on brain function.
- Zinc is only needed in small amounts but is important to immune system function, which is critical during the winter months.
Studies show that filling nutritional gaps with multivitamins can improve your focus and energy during tasks if you are deficient in a key vitamin or mineral that contributes to energy or brain function.
Some herbs have proven to be useful in improving energy as well:
- Ashwagandha helps your body regulate its cortisol, a hormone involved in both alertness and stress.
- Licorice root helps protect your nervous system from large amounts of cortisol in cases of chronic stress.
There are also some non-nutritional strategies.
More Natural Ways to Boost Energy and Fight Winter Fatigue
Sun Lamp
To replicate the energizing effects of the sun and get your circadian rhythm back on track, you can try out a sun lamp. Your best bet is to expose yourself to this bright light right when you wake up, spurring your body to produce more of the chemicals that make you feel awake in the morning.
Shut Off Devices Early Before Bed
A sun lamp, combined with not using technology 1-2 hours before bed, can help reset your circadian rhythm so that you’re awake in the morning and tired at night. This only really helps if you’re sticking to your circadian rhythm by consistently going to bed and waking up at the same time every day.
Become More Active
Exercise helps with energy in more ways than one. Not only does it increase oxygen and blood flow to the brain, making you feel more alert, but it also causes the release of endorphins, which are feel-good chemicals that help your mood and energy levels. For some, exercising in the morning can be a great way to jump-start your energy for the day, but even if morning workouts are not your cup of tea, getting your sweat on will still help with your energy for the day.

Conclusion
Winter fatigue is not inescapable! If you’re experiencing it, start by addressing the basics: ensure you’re getting enough sleep and proper amounts of essential vitamins and minerals, like vitamin D, B vitamins, magnesium, and iron, which are vital for energy production and overall well-being. Supplements can be a great tool to fill nutritional gaps, especially when fresh produce is harder to come by.
Getting your body moving and getting as much bright light as you can will help too. Exercise helps you produce feel-good chemicals and bright light helps reset your circadian rhythm, as long as you stick to the same sleep and wake times consistently. With the right mix of nutrition, movement, and self-care, you can shake off winter fatigue and embrace the season with more energy.
