Seasonal affective disorder (SAD) is a type of depression that’s related to changes in seasons. SAD begins and ends at about the same time every year.
The specific cause of seasonal affective disorder remains unknown.
Some factors that may come into play include:
If you’re like most people with SAD, your symptoms start in the autumn and continue into the winter months, sapping your energy and making you feel moody.
Treatment for SAD may include light therapy, medications and psychotherapy.
Don’t brush off that yearly feeling as simply a case of the “winter blues” or a “seasonal funk” that you have to tough out on your own. Take steps to keep your mood and motivation steady throughout the year.
In most cases, seasonal affective disorder symptoms appear during late autumn or early winter .Symptoms may start out mild and become more severe as the season progresses.
Take signs and symptoms of seasonal affective disorder seriously. As with other types of depression, SAD can get worse and lead to problems if it’s not treated.
These can include:
For decades, doctors have recommended light therapy for treating mood and sleep problems.
This is because part of your brain’s hypothalamus (often referred to as the body clock) uses the light found in natural sunlight, to regulate your body’s cycles.
When the light passes through the eyes into the brain, serotonin is released. During the winter, there is less daylight than in the spring and summer, which causes a drop in the body’s serotonin levels.
Serotonin is an important chemical in the brain known as a neurotransmitter. A neurotransmitter is a molecule in the brain that helps nerve cells to work together. One of the roles serotonin has in the brain is to act as a traffic cop to other neurotransmitters. Without enough serotonin, a wide range of body functions is affected, including mood.
Less daylight is a trigger for the body to increase production of a certain hormone – melatonin. The role of melatonin is thought to help in the sleep process. The body releases it at night, during sleep.
Together, the lack of serotonin (which helps nerve cells cooperate) and the increase in melatonin (which put a body to sleep) cause SAD.
If you struggle with sleep, mood, or energy, your body clock may not be responding properly to normal light signals.
Light therapy works by simulating the light found in natural daylight to reset the circadian rhythm.
By providing summertime levels of light during the winter, light therapy users can successfully alleviate the symptoms of SAD, with the result being that former sufferers can lead a normal, happier life and beat the ‘Winter Blues.’
In fact almost everyone can benefit from increased energy levels when using Light Therapy.
