Seasonal Affective Disorder: 7 Signs to Look For
Leaving this untreated can lead to more chronic conditions.

Dreary, gray skies and frigid temps can make anyone feel a bit lethargic, but seasonal affective disorder goes beyond having the winter blues or blahs. Seasonal affective disorder is a depressive episode that is triggered by seasonal changes, typically the colder months of fall and winter. (It is less common, but possible, to have seasonal affective disorder in the transition from spring to summer.) The symptoms of seasonal affective disorder during winter months are the same as a regular episode of depression, including:
-
Not enjoying activities you previously did
-
Lack of energy
-
Withdrawal and isolation
-
Overeating
-
Gaining weight unintentionally
-
Craving carbohydrates
-
Feeling disengaged from surroundings
Signs of seasonal affective disorder in the spring/summer may differ slightly and include symptoms like poor appetite, weight loss, insomnia, and restlessness.
For a seasonal affective disorder diagnosis, these symptoms need to be present for weeks or even months, not just a few days. The other requirement is that the depressive episode must occur for at least two years during the specific season.
You may not consider finding treatment for seasonal affective disorder since you know winter is only temporary, but this is a mistake: “The fact of the matter is that it does last,” says psychologist Jennifer Hartstein, PsyD, a psychologist based in New York City. “It can be pervasive and it can lead to more chronic depressive disorders.”
Seasonal affective disorder is typically treated with one of the following methods:
-
Antidepressant medications
-
Psychotherapy
-
Light therapy

00:00:02,540 --> 00:00:05,870
Seasonal affective disorder and
depression are really the same thing.
3
00:00:05,870 --> 00:00:13,001
The only difference is that SAD
tends to occur around the seasons.

00:00:15,066 --> 00:00:18,763
Seasonal affective disorder
is a depressive disorder
6
00:00:18,763 --> 00:00:22,570
that happens usually during the fall,
early winter.
7
00:00:22,570 --> 00:00:26,410
It can also occur as spring goes
into summer, but that's less common.
8
00:00:26,410 --> 00:00:29,020
The winter blues
are something most of us get.
9
00:00:29,020 --> 00:00:31,465
It's cold, it's not as light outside.
10
00:00:31,465 --> 00:00:32,506
We all need sun and vitamin D,
11
00:00:32,506 --> 00:00:35,903
that's something we all need.
SAD affects people's functioning really
12
00:00:35,903 --> 00:00:37,845
the same way that depression might.
13
00:00:37,845 --> 00:00:41,120
They tend to not enjoy
things that they once did.
14
00:00:41,120 --> 00:00:46,130
They don't have enough energy to
initiate behaviors, initiate projects.
15
00:00:46,130 --> 00:00:47,900
They don't tend to wanna socialize.
16
00:00:47,900 --> 00:00:49,750
They tend to wanna stay in.
17
00:00:49,750 --> 00:00:55,246
They tend to overeat,
gain weight, crave carbohydrates,
18
00:00:55,246 --> 00:00:59,893
and just really sort of
feel disengaged from life.
19
00:00:59,893 --> 00:01:02,914
And that can go on for days, or
in more severe cases, weeks or
20
00:01:02,914 --> 00:01:05,563
even months.
Seasonal affective disorder could be
21
00:01:05,563 --> 00:01:08,804
treated in the same way that you would
treat someone that has a major depressive
22
00:01:08,804 --> 00:01:09,306
disorder.
23
00:01:09,306 --> 00:01:13,569
It would depend on the symptoms and the
severity of the symptoms, and the degree
24
00:01:13,569 --> 00:01:16,924
of impairment and suffering that one has.
Medication,
25
00:01:16,924 --> 00:01:20,780
you would treat it just sort of similarly
to the way you would treat depression.
26
00:01:20,780 --> 00:01:24,380
Psychotherapy using cognitive
behavioral techniques,
27
00:01:24,380 --> 00:01:28,131
psychodynamic techniques of
engagement with the patient.
28
00:01:28,131 --> 00:01:30,400
And light therapy is the one
that's a bit unique.
29
00:01:30,400 --> 00:01:36,450
So light therapy really initiated in
the 80s as a way of supplementing and
30
00:01:36,450 --> 00:01:39,970
replacing the lost light
that a person's not getting.
31
00:01:39,970 --> 00:01:41,600
If you maybe are concerned or
32
00:01:41,600 --> 00:01:46,270
suspect that you have seasonal affective
disorder due to the cyclical nature of
33
00:01:46,270 --> 00:01:50,530
your symptoms changing as the seasons
change, I would recommend seeking
34
00:01:50,530 --> 00:01:54,890
out a mental health provider and
having a full evaluation and talking about
35
00:01:54,890 --> 00:01:58,508
the treatment options and recommendations.
I think that there are some common
36
00:01:58,508 --> 00:02:00,630
misconceptions about
seasonal affective disorder.
37
00:02:00,630 --> 00:02:01,600
That it doesn't matter.
38
00:02:01,600 --> 00:02:02,700
It's no big deal.
39
00:02:02,700 --> 00:02:03,580
You'll get over it.
40
00:02:03,580 --> 00:02:04,590
It doesn't last.
41
00:02:04,590 --> 00:02:06,700
But the fact of the matter
is is that it does last.
42
00:02:06,700 --> 00:02:10,900
And it can be pervasive, and it could lead
to more chronic depressive disorders.
43
00:02:10,900 --> 00:02:13,920
So get out there and treat it and
then you'll feel better.
44
00:02:13,920 --> 00:02:18,751
