As humans, we have a complex relationship with the environment around us. Our emotions and moods are often influenced by external factors, including weather patterns. Weather is known to have a significant impact on our mood, and this connection between the mind and environment is mediated by an array of neurochemicals, hormones, and the immune system.
In an interaction with ABP Live, Dr Sameer Malhotra, Director and Head, Department of Mental Health and Behavioural Sciences, Max Multi Speciality Centre, Panchsheel Park and Saket, stated that "The hypothalamus, a small but crucial part of the brain, plays a crucial role in regulating mood, hormones, and circadian rhythm. This rhythm is the natural rhythm between our body and the external environment that we live in. The hypothalamus functions like a biological clock, and it tries to synchronize our inner self, timing, sleep-wake cycle, and mood with the external environment."
Changes in weather can have a profound impact on our mood and well-being. "During the winter months, shorter days and reduced exposure to sunlight can lead to depression, lethargy, and a general feeling of malaise. Conversely, during the summer months, longer days and increased exposure to sunlight can lead to a sense of euphoria and heightened activity levels. This is particularly true for individuals with SAD, who may experience hypomania or mania during the summer months and depression during the winter months," Dr Malhotra said.
In clinical depression, one of the key biological symptoms is worsening mood and lethargy, particularly in the morning hours. A healthy lifestyle, regular sleep-wake schedule, and timely recognition and treatment of mood disorders can all help to mitigate the impact of weather-related mood changes, the doctor said.
It is worth noting that in a small percentage of people, a reverse seasonal affective disorder can occur. This condition is characterized by summer depression and winter mania, and it can be just as debilitating as more traditional forms of SAD.
Dr Malhotra also said: "As a doctor, I often see patients who struggle with mood disorders, particularly during the winter months. If you are experiencing symptoms of depression, such as a persistent low mood, loss of interest in activities you used to enjoy changes in appetite or sleep patterns, feelings of worthlessness or hopelessness, or suffering from sustained hyperactivity, hypomania, or mania. It is essential to seek help."
International standard guidelines for the diagnosis and treatment of mood disorders recommend a range of evidence-based therapies, including cognitive-behavioural therapy (CBT) and medication. Lifestyle changes, such as getting regular exercise, eating a healthy diet, and maintaining a consistent sleep schedule, can also be helpful in managing symptoms, the doctor added further.
Our connection to the environment is complex and multifaceted. The impact of weather on our mood and well-being is just one example of this complex relationship. By understanding the role that the hypothalamus plays in regulating mood and circadian rhythm, and by taking steps to manage mood disorders, we can all work towards achieving a better balance between our inner selves and the external environment.
