SAD- Seasonal Affective Disorder

Selca of the day!

The weather is getting cooler. It's entering Autumn.
However, I am having sleeping disorder recently.
I couldn't sleep well at night and end up sleepy during daytime, then I took some coffee to stay awake, then I couldn't sleep at night due to caffeine effect.
This happened to me for continous night.
And I am getting hungry during night before going to bed.

So, I did some researched and found something interesting.
SAD is abbreviation to Seasonal Affective Disorder.

The U.S. National Library of Medicine notes that "some people experience a serious mood change when the seasons change. They may sleep too much, have little energy, and may also feel depressed. 

The symptoms often begin in the autumn as the days start getting shorter. They are most severe during December, January and February.

Symptoms of SAD may consist of difficulty waking up in the morning, morning sickness, tendency to oversleep and over eat, especially a craving for carbohydrates, which leads to weight gain.

What causes SAD?

The exact cause of SAD is not fully understood, but it is thought to be linked to reduced exposure to sunlight during the shorter days of the year.

Sunlight can affect some of the brain's chemicals and hormones. However, it is not clear what this effect is. One theory is that light stimulates a part of the brain called the hypothalamus which controls mood, appetite and sleep. These things can affect how you feel.

In people with SAD, a lack of sunlight and a problem with certain brain chemicals stops the hypothalamus working properly. The lack of light is thought to affect:

• the production of the hormone melatonin
• the production of the hormone serotonin
• the body's circadian rhythm (the body's internal clock, which regulates several biological processes during a 24-hour period)

So true! I am getting hungry easily recently.
And also craving for carbs, especially bagel! OMG!
My diet plan is going to fail again soon! OMG OMG!
I won't let this happen!

Huhu! Hope I can adopt to the change of weather soon!
