New Year's and Christmas Mood: Neurobiology, Cultural Psychology, and Ritual

Introduction: Mood as a Complex Phenomenon

“New Year's mood” is not just a common expression, but a complex psychophysiological and sociocultural phenomenon that combines a complex of emotions, cognitive attitudes, and behavioral reactions. From a scientific point of view, it is the result of the interaction of several factors: seasonal biological changes, cultural programming through rituals, social expectations, and individual memory. Christmas mood, with a more pronounced religious and family character, often acts as its constituent part or basis, forming a unified festive chronotope lasting from late December to the first week of January.

Neurobiological foundations: the chemistry of the holiday

The subjective feeling of the holiday has a material basis in the brain, related to the work of neurotransmitters and hormones.

1. Dopamine — a neurotransmitter of expectation and reward. The preparation period (Advent, choosing gifts, planning) stimulates its production. The anticipation of the holiday (“dopamine anticipation”) often turns out to be even stronger than the experience of the event itself. This hypothesis is confirmed by studies showing the peak of happiness in people before vacation.

2. Serotonin and melatonin — regulators of seasonal rhythms. In winter, with the shortening of daylight hours, the level of serotonin (“the hormone of good mood”) may decrease, which contributes to seasonal affective disorder. However, bright festive lighting (garlands, lights) and rituals are a cultural mechanism of compensation for this deficit, artificially stimulating vitality.

3. Oxytocin — the “hormone of attachment”. It is activated during family gatherings, banquets, gift-giving, and physical contact (hugs, kisses under the mistletoe). It strengthens the feeling of trust, closeness, and warmth, which is a key component of the Christmas mood.

4. Endorphins are released during laughter, festive feasting, consumption of moderate amounts of dark chocolate or spicy food (part of traditional festive dishes), creating a light euphoria.

Cultural psychology and the power of rituals

Mood is constructed and maintained by a system of repetitive rituals that perform important psychological functions:

• Creation of predictability and control. In the world of uncertainty, rituals (setting up the Christmas tree, preparing certain dishes, watching the same movies) give a sense of stability, order, and safety. This reduces anxiety.

• Formation of collective identity. Joint performance of traditions (caroling, singing carols, launching fireworks on New Year's Eve) creates a strong sense of community, a “we-feeling”, overcoming loneliness.

• The magic of nostalgia. The smell of tangerines and pine, the sounds of certain melodies (“The Nutcracker”, Last Christmas), the taste of Olivier — all these are triggers of autobiographical memory. They activate emotional centers of the brain associated with childhood memories, creating a warm, idealized “effect of the past”. This phenomenon is known as nostalgic animation, which, as research shows, increases psychological well-being.

Social pressure and “mandatory happiness”: the flip side of mood

Holiday mood is not an universal experience. Sociologists and clinical psychologists identify the phenomenon of “holiday depression” or syndrome of “mismatch with the holiday”. Its causes:

• Dissonance between social expectations of universal joy, family idyll, and generosity — and personal circumstances (loneliness, grief, financial difficulties, family conflicts).

• Syndrome of emotional burnout from excessive preparation, shopping, culinary marathon.

• Increased attention to the absence of loved ones, which intensifies the feeling of loss.

An interesting fact: in Western culture, even the term “Christmas Blues” exists. Research records an increase in requests for psychological help and the number of suicides during this period, which refutes the myth of unconditional joy of holidays.

Globalization and commodification of mood

New Year's and Christmas mood has become a powerful commercial product. Its “sales” are handled by the industry:

• Advertising and cinema, forming idealized visual and narrative canons of the holiday (snow-covered houses, ideal families, mandatory happy ending).

• Marketing, turning gifts from a symbolic gesture into an obligatory and often stressful practice of consumption.

• Tourism, offering trips to the “most atmospheric” Christmas fairs in Europe.

This leads to the globalization of a certain (often North American or Central European) image of the holiday, which superimposes on local traditions.

Conclusion: Between biology, culture, and commerce

Thus, New Year's and Christmas mood is not a spontaneous emotion, but a complex resultant vector of biological predispositions, cultural programming, social pressure, and personal experience. This state is consciously constructed and maintained by society, culture, and economy through a system of rituals, media, and the market. It has a powerful psychotherapeutic potential, offering a structure, meaning, and peaks of positive emotions in the dark time of the year, but at the same time, it can become a source of stress for those who do not fit into its ideal canon. Understanding these mechanisms allows for a more conscious approach to holidays, cultivating truly meaningful aspects for oneself and reducing the pressure of imposed standards, in order to create one's own, authentic mood.
