As the days grow shorter and outdoor temperatures drop, many people notice a strange shift in their mood and energy levels. Commonly called the "winter blues," this seasonal slump can sometimes carry feelings of lethargy, sadness, and a lack of motivation. For some, these feelings become more severe, developing into Seasonal Affective Disorder (SAD)—a form of depression that occurs during the colder, darker months of the year. Studies estimate that SAD affects approximately 10% of adults across the globe, with more cases being found in areas with less daily sunlight exposure (i.e., Alaska, northern Europe, etc.). Reduced sunlight, shorter days, and colder weather are key factors contributing to this seasonal mood disorder, which can disrupt circadian rhythms, appetite, and overall mental health.¹

While the challenges of battling winter seem daunting, engaging in physical activity can be a powerful medicine to enhance your spirits. Exercise is a natural mood booster that increases the production of endorphins, improves sleep, and provides a sense of accomplishment. In fact, many studies over the years have found that both regular exercise and exposure to light positively affect mood, endurance, and weight loss during the winter months.^{2, 3} 

In this article, we’ll explore the definition of SAD and why it occurs, discuss the mental health benefits of exercise, and offer practical ideas for staying active both indoors and outdoors this winter. Don’t let the winter blues get you down. If you’re dealing with SAD or hoping to maintain your health and fitness through winter, then get your body moving inside or outside this season.

What is Seasonal Affective Disorder (SAD)?

Seasonal Affective Disorder (SAD) is a type of depression that follows a seasonal pattern, most commonly occurring during the darker, colder months. It is classified as a subcategory of major depressive disorder and is recognized by its cyclical nature—symptoms appearing as daylight hours diminish and often subside with the arrival of more daily sunlight. Unlike occasional feelings of sadness or lethargy, SAD can significantly impact daily functioning and quality of life. Common symptoms of SAD include:⁴

• Persistent low mood or sadness
• Loss of interest in activities once enjoyed
• Excessive fatigue or low energy levels
• Difficulty concentrating or making decisions
• Oversleeping or changes in sleep patterns
• Intense cravings for carbohydrates lead to weight gain
• Feelings of hopelessness, worthlessness, or guilt

What Causes Seasonal Affective Disorder?

The cause of Seasonal Affective Disorder is relatively unknown; however, it is primarily linked to the changes in daylight and weather during the fall and winter months. One of the main causes is the reduced exposure to sunlight, which disrupts the body’s circadian rhythm. This biological process regulates sleep, mood, and hormones; a lack of natural light can throw it out of whack. Sunlight also plays a crucial role in producing serotonin, a neurotransmitter that influences mood and energy levels. With less sunlight, serotonin levels drop, which can contribute to the persistent sadness and lack of motivation characteristic of SAD.⁵

Other contributing factors to SAD include increased melatonin, a hormone that regulates sleep. During winter, the body may produce more melatonin than normal, causing excessive drowsiness and lethargy throughout the day. Your genetics may also play a role, as a family history of depression or SAD may make you more susceptible to these symptoms. 

Environmental factors such as living in higher latitudes with less daylight can also exacerbate the effects of SAD. Understanding these potential causes of SAD highlights the importance of proactive measures to mitigate its effects and occurrence throughout the winter.

Mental Health Benefits of Physical Activity

Physical activity is more than just a way to stay “in shape”—it’s crucial to improving overall mental health. Regular exercise has been shown to significantly affect mood, energy levels, and mental well-being, making it a powerful tool for combating the winter blues. Even in small doses, more daily movement provides many mental health benefits. Below are some of the key ways exercise can improve mental health:^{6, 7, 8 , 9}

• Enhanced Mood: Physical activity triggers the release of endorphins, called the "feel-good" hormones, which naturally reduce stress and help prevent depressive symptoms.
• Reduced Stress: Exercise minimizes cortisol levels throughout the day, allowing for a greater feeling of calmness and relaxation. 
• Improved Sleep: Regular movement can regulate sleep patterns, making it easier to fall asleep and stay asleep.
• Boosted Energy Levels: Exercise (specifically aerobic exercise) increases energy by improving blood flow and oxygen delivery.⁷
• Enhanced Self-Esteem: Achieving fitness goals, even just finishing a workout you didn’t feel like doing, fosters a sense of accomplishment and boosts self-confidence.
• Social Connection: Group workouts or team sports provide opportunities to connect with others, reducing feelings of isolation in the winter.
• Cognitive Benefits: Exercise promotes better focus and memory by increasing blood flow to the brain.¹⁰

Indoor Workouts to Try This Winter

Indoor workouts are a convenient and effective way to stay active and maintain mental and physical health when the weather outside is cold, dark, or icy. Working out inside can also help you stay consistent with your fitness goals from the comfort of your home, reducing stress about making time for exercise during the day. Due to the wide variety of app-based workouts, there are countless options to suit your preferences, space, budget, and access to equipment. Here are some indoor workout ideas to try at home:

• Yoga: Perfect for improving flexibility, reducing stress, and fostering mindfulness. Online classes or apps make it accessible to everyone.
• High-Intensity Interval Training (HIIT): Short bursts of intense activity and rest periods provide an efficient, calorie-burning workout. You can find free HIIT workouts online or do short, high-intensity bursts of activity around the house, such as going up and down the stairs, jumping jacks, or jogging in place.
• Bodyweight Strength Training: Exercises like push-ups, squats, and planks build strength and require no equipment. You can do them anywhere and quickly build sufficient full-body strength.
• Dance Workouts: Fun and energetic dance routines like Zumba or Jazzercise combine cardio with strength-building in one fun workout.
• Pilates: Both reformer—and mat-based Pilates help improve posture and core strength through low-impact muscle-building movements. 
• Indoor Cycling: A stationary bike provides a low-impact cardio workout, with virtual classes adding motivation and structure. 
• Resistance Band Exercises: Resistance bands can be used for strength training or stretching routines anywhere you are, which makes them a great option for traveling and at home or for those working through injuries and chronic pain.

Outdoor Workouts During Winter

It may seem extra challenging to exercise outdoors in the winter, but it can be an invigorating and pleasant experience with the right mindset and gear. Exercising in the fresh, crisp air increases exposure to natural light, which is necessary for reducing symptoms of SAD.^{7, 9} 

Outdoor workouts provide an opportunity to break out of indoor monotony, connect with nature, and experience the unique beauty of winter. Here are some great outdoor workout ideas to try this winter:

• Snowshoeing: This is a fantastic full-body workout that’s easy to learn and easy on the joints. It is also an excellent way to explore beautiful snowy landscapes while exercising.
• Ice Skating: An activity for the whole family to enjoy, ice skating offers a fun way to build leg and strength while improving balance and coordination.
• Skiing: Both downhill and cross-country skiing offer excellent full-body workouts that target cardiovascular fitness, strength, and balance while enjoying beautiful winter views. 
• Running or Jogging: Running in colder weather can be refreshing and help you maintain your routine year-round. Dress in layers, wear extra traction on your shoes to stay safe in slippery conditions and warm up properly before heading out to reduce the risk of injury.
• Sledding: Turn a fun winter pastime into a workout by walking or jogging uphill after the thrilling ride down. It’s a playful way to build strength and stamina while having fun in the snow.

Additional Tips for Maintaining Mental Health

While physical activity is extremely helpful in reading the winter blues, it is also important to incorporate other strategies that can further support mental health during the colder months. Increasing light exposure, focusing on a healthy diet, and making time for self-care can create a holistic plan to maintain your emotional and mental well-being. 

Check out these non-movement-related strategies for creating a happier and healthier winter season:  

• Light Therapy: Using light therapy lamps mimics natural sunlight, helping regulate your body’s internal clock and boosting those “feel good” hormones.
• Healthy Diet: To support brain health, eat a diet rich in omega-3 fatty acids, vitamin D, and whole grains.
• Practice Mindfulness: Meditation, journaling, or deep breathing exercises help reduce stress and promote relaxation. Many meditative exercises are available on apps or free online resources.
• Social Connection: Stay connected with loved ones through virtual chats, phone calls, or group gatherings to combat feelings of isolation.
• Adequate Sleep: Establish a consistent sleep schedule of at least 7-9 hours each night to ensure proper rest and prevent fatigue.
• Find Creative Hobbies: Activities like painting, knitting, or playing music provide a therapeutic outlet for stress and enhance creativity.⁹
• Try a Cold Plunge: Dunking your body in ice-cold water can stimulate the release of endorphins, improve circulation, and enhance mental clarity, contributing to an overall sense of positive well-being.¹¹ 

Understanding Seasonal Affective Disorder (SAD) and its causes is the first step in combating any feelings of depression or irritability during the colder months. Physical activity via indoor and outdoor activities is an incredibly effective strategy to boost mood, improve energy levels, and reduce stress despite shorter days and frigid temperatures. 

Winter doesn’t have to feel like a season to “get through”—it can be an opportunity to prioritize mental and physical health at the start of the new year. Start small, find activities you enjoy, and commit to taking proactive steps toward a healthier, happier winter.
