When winter comes, many people feel sluggish, lack motivation and have difficulty maintaining energy levels like at other times of the year.
According to neurologists, this condition is not simply laziness but a complex biological reaction of the body to a cold environment and lack of light.
Dr Kunal Bahrani, Chairman and Director of the Neurology Department at Yatharth Hospital (India), said that the brain experiences many changes in winter, leading to low mood, vague thinking, intermittent sleep and a feeling of emotional heaviness.
These manifestations are especially common in urban areas, where people spend most of their time indoors.
The first reason for the sharp decline in energy is the lack of sunlight. According to Dr. Bahrani, sunlight not only brings a warm feeling but also regulates circadian rhythm, promotes serotonin production and maintains alertness.
When the day is shorter and the level of exposure decreases, even healthy people have difficulty concentrating, motivating and balancing emotions.
In addition, winter air pollution is a contributing factor to "brain fog". Poor air quality reduces memory, making the brain heavy and unable to stay alert.
When its cold, physical activity decreases and screen time increases, disrupting the cycle of dopamine and serotonin, two neurotransmitters that control emotions and energy.
Reducing excretion also reduces vitamin D synthesis, an important factor for cognitive function.
All of these factors resonate, creating a state of sluggish winter. According to scientists, this is a natural reaction, not a lack of will.
However, if it persists, this condition can develop into seasonal affective disorder (SAD), a form of weather-related depression.
To improve, experts recommend taking a morning sun bath from 1520 minutes to reset your circadian rhythm.
For less sunny days, light therapy lights are an effective alternative, widely used in cold countries.
Maintaining regular exercise, limiting screens before bed, eating nutritious foods and drinking enough water also help improve energy.
If the fatigue persists, the doctor warns against being subjective. Continuous fatigue or persistent depression can be associated with vitamin B12 deficiency, thyroid disorder or clinical depression, problems that require professional treatment.
Winter can slow down the body's performance, but understanding the causes and adjusting your lifestyle properly will help people maintain mental health and stable energy throughout the cold season.
