Seasonal Affective Disorder (SAD) is a type of depression caused by the change in seasons. It manifests itself in many ways and has wide range and degree of symptoms.

These symptoms can differ from winter to winter, but are consistently associated with seasonal mood changes. SAD symptoms include:

  • Oversleeping
  • Sleepiness during the daylight hours
  • Low energy
  • Trouble concentrating
  • Low to no motivation to exercise
  • Carbohydrate cravings
  • Weight gain
  • Withdrawal from social situations
  • A down, depressed mood during specific months

 

The Power of Light for Seasonal Affective Disorder

Production of serotonin (a.k.a. "The Happiness Hormone") is triggered by bright light like sunlight in the summer. Serotonin helps calm the brain’s response to stress and boosts overall feelings of happiness. This is why people tend to feel happier and more energetic on a bright, sunny day.

Serotonin has widespread effects on our mood and behavior, so when we are deprived of light, our mood, energy and sleep falter. Light deprivation and its symptoms - experienced by many due to climate or lifestyle - is a result of our body’s biological response to the lack of light.

Light therapy exposes you to a bright light that mimics the sun and is a natural way to boost serotonin. By integrating SAD light therapy into your daily routine, you can offset the affects of light deprivation and resulting seasonal disorders.

For many people the cost of light therapy lights can be a major deterrence. Luckily, the Weyburn Public Library just recently purchased two high quality light therapy lamps for the public to enjoy while they're visiting the library.
