When Weather Affects Your Mental Health: Understanding Seasonal Affective Disorder

Most people have felt their mood drop when the skies go grey. Some days feel heavier than others. The body slows down. The mind feels foggy. These shifts can feel small or they can feel strong. Many people notice these changes but do not always connect them to the seasons. That is because no one really talks about how the weather affects the mind. It just feels like a bad day or a tired week. But the truth is many of these patterns have names and reasons. One of them is called Seasonal Affective Disorder. It is not a flaw in your personality. It is not a weakness. It is a real pattern that affects how people feel across the year. There is research behind it. There is science behind it. These changes are not all in your head. Some people feel it more than others. But no one is imagining it.

At HULM Training and Development the focus is to help people understand what is happening and find simple ways to manage it. This article will explain how weather, sunlight and the body are all connected.

What Seasonal Affective Disorder actually is?

Seasonal Affective Disorder is a type of depression that comes and goes with the seasons. Most people think it only happens in winter. But that is not true. Some people feel low during the spring or summer. Others feel better when days are shorter. These patterns are not the same for everyone. SAD is marked by mood changes that return every year during a specific time. People often feel tired. Some feel numb. Others feel sad or slow. There can be changes in sleep. Some people sleep more. Some sleep less. Many lose interest in things they once enjoyed. The signs are real. They are not always loud. But they repeat in a clear pattern.

Research shows that people can have different peaks. Some feel it stronger in December. Others in April. There is no one rule. Some people never feel these shifts at all. That is why it helps to look at patterns across more than one year. At HULM Training and Development, people are not boxed into categories. Instead, they are guided to understand their own rhythm. That is where real help begins.

The science of sunlight, serotonin, and mood cycles

The brain works in cycles. Light plays a big part in that. The body produces serotonin when the body receives sunlight. It is a chemical that makes you feel stable and relaxed. It also assists in the management of sleep and energy. The brain can produce less serotonin when there is less light. This may result in depression or fatigue.

Sunlight also tells the body when to wake and when to rest. That is called your circadian rhythm. Shorter days can confuse that rhythm. People may feel sleepy in the afternoon. Or they may feel alert at night when they want to rest. Melatonin is also part of this. It is a hormone that helps with sleep. In darker months, the body can make more melatonin. That can make people feel slower during the day. A study from 2025 in npj Mental Health Research found that shorter daylight was linked to stronger feelings of depression. They also found that mood was affected by both light and temperature. These are real body changes. They are not signs of failure. HULM Training and Development helps people learn about these shifts so they can feel less confused and more in control.

Why seasonal mood changes do not affect everyone the same way

Not everyone feels the weather in the same way. Some people love the winter. Others feel heavy the moment summer arrives. The RADAR-MDD study found that people fall into different groups based on how their emotions change with the seasons. Some feel worse when it is dark. Others feel low when the days are long. There are also links with age and gender. Younger adults and women showed stronger seasonal effects in the research. This is not about making general rules. It is about noticing what is true for you. Some people can go through the whole year without any mood shift at all. Others feel different every few months. That is why it is not helpful to compare yourself with others. The goal is not to fit a chart. The goal is to understand your own pattern.

HULM Training and Development focuses on that personal approach. They do not give labels and move on. They help people see what their own cycle looks like. That way, each person can get the right kind of support that makes sense in their life.

How weather influences activity levels and emotional health together

The connection between the extent of movement and the level of feeling exists. When the mood is depressed, individuals are less active. Once individuals cease to move, they become even worse. Weather plays a role in this. In case of a rainy day or two, it is more difficult to go out walking. In hot or cold weather, people remain indoors. That is to say that the body remains motionless. And the mind gets stuck too. Studies indicate that movement and mood influence each other.

In a recent study, it was found that the effect of mood changes on the activity was greater than the effect of the weather itself. It is not only the weather, that is. It is the feeling of the individual in it. And it is that emotion that then influences their next action. This too varies with each individual. One can go out and walk in the rain and feel better. Another might require sunshine to get up. That is the reason why not every one can be helped by simple advice. At HULM Training and Development, it is all about your routine. They look at how you live. Then they assist you in forming habits that do not oppose your energy, but rather contribute to it.

Signs your mood may be following a seasonal pattern

Seasonal mood shifts do not always come with big signs. Sometimes they show up quietly. You may feel low during the same months every year. You may sleep more during winter or feel restless during summer. You may stop reaching out to people or lose interest in things you love. These things can seem small at first. But when they repeat year after year, they become part of a cycle. That is why tracking patterns helps. Looking back over the past few years can show you if there is a trend. Not every bad day is a sign.

But if the same feelings come around each season, it is worth paying attention. You do not need to label yourself. You do not need to fix it alone. At HULM Training and Development, people are supported to map these patterns clearly. The goal is not to find what is wrong. It is to find what has been repeating. From there, the support becomes more focused and calm.
