The Psychology Behind Sunny Days
When we wake up in the morning and sunlight enters through the curtains, can that sunlight really change how we feel about the rest of the day?
On a sunny morning, going outside, taking a walk, meeting friends, or sitting at a café may feel more appealing. Moreover, we do not always need to have a specific plan to do so. Sometimes, simply thinking, “The weather is so nice; maybe I should go outside for a while,” can change the course of the day.
For example, let us think about a task we have been putting off for days. Going to the post office, doing the grocery shopping, stopping by the pharmacy, delivering a document, or finally going to pick up something we have needed for a while—these are not necessarily major tasks, yet they can sometimes feel overwhelming. On a cloudy or rainy day, these tasks may seem even more demanding. Getting ready to leave the house, walking in the rain, or taking public transportation can feel like a burden in itself. On a sunny day, however, the same person may think, “Since the weather is nice, I might as well take care of this while I am out.”
Sometimes, sunny weather can also serve as a starting point for completing small responsibilities that have been postponed. Washing a car that has needed cleaning for weeks, organizing things that have accumulated on the balcony, going to the market, shopping, or taking care of things around the house may begin to seem more manageable when the weather is pleasant. The thought “I will take care of this today” may arise not only from the task itself, but also from the fact that going outside to complete it now seems easier and more enjoyable.
A similar pattern can be observed in our social lives. When a friend we have not seen for a long time messages us, we may be more likely to say, “Let’s meet another day,” when the weather is gloomy. On a sunny day, however, it may feel easier to respond, “Sure, where shall we meet?”
On a rainy day, the same process may work in the opposite direction. Getting ready to go to the post office, taking an umbrella, walking in the rain, trying not to get wet, or reaching public transportation may seem more difficult than it actually is. In such situations, saying “I will go tomorrow” may feel easier. The need to go to the post office has not disappeared; rather, the behavioral cost of accomplishing it may seem greater.
Therefore, the psychological effects of sunny weather are not limited to the fact that the sky is clear. Sunlight can also be considered an environmental stimulus that influences how individuals interact with their surroundings and how they engage in their daily behaviors.
Underlying this change may be not only our thoughts about the weather but also the effects of light on human biology. Sunlight is one of the most important environmental cues that helps our bodies recognize what time of day it is. In particular, exposure to natural light in the morning plays an important role in regulating the circadian rhythm, an approximately 24-hour biological cycle.
The circadian rhythm allows many biological processes, including sleep and wakefulness, hormone release, body temperature, and metabolism, to follow a relatively organized pattern throughout the day. Therefore, receiving natural light in the morning does more than simply make our surroundings brighter; it also sends the brain a biological signal indicating that “the day has begun.”
The hormone melatonin also plays an important role in this process. Melatonin increases particularly in darkness and contributes to the regulation of sleep timing. As exposure to daylight increases, the suppression of melatonin production helps the body transition into a more alert state in the morning. Therefore, part of the sense of vitality experienced on a sunny morning may be related to the effects of light on our sleep–wake cycle.
However, the effects of sunlight on our mood cannot be explained solely through alertness. The relationship between light and mood is also connected to systems involved in the regulation of emotional states. In particular, changes in the duration of exposure to daylight are known to be associated with seasonal changes in mood in some individuals. During the winter months, shorter days and reduced exposure to natural light may be associated with the emergence of depressive symptoms in some people.
Serotonin is also one of the neurotransmitters that may play a role in this relationship. Serotonin is involved in the regulation of mood, sleep, and various behaviors, and its relationship with exposure to daylight is considered one of the possible mechanisms through which sunlight may influence mood. However, it would not be accurate to provide a single biological explanation suggesting that sunlight directly “makes people happy.” Mood is shaped by the interaction of numerous biological and psychological factors.
Does the Sun Really Make Us Feel Better?
The effects of sunlight on our mood cannot be attributed to a single factor. Our biological rhythms, level of alertness, emotional state, and daily behaviors interact with one another. Therefore, understanding why a sunny day may make us feel better requires considering the combined effects of light on our bodies and our behavior.
Daylight is not merely an element that makes our surroundings brighter; it is also an important environmental factor that helps regulate our biological rhythms and can shape our daily behaviors. In addition, sunny weather may make behaviors such as going outside, being physically active, and engaging in social interactions more accessible, thereby influencing our mood indirectly. Thus, feeling better on sunny days can be understood as a multidimensional experience that emerges from the interaction between the biological effects of light and psychological and behavioral processes.
