I always feel very tired when the weather is cold, and I often sleep far and wide. Is this a disease?

If you can't help sleeping during the day, it may be narcolepsy.

Symptoms and manifestations of narcolepsy

1. Sleepy patients fall asleep when they don't want to sleep or shouldn't. For example, when they laugh or get angry, surprised or shocked while eating, driving or working, they will have symptoms of paralysis or inability of head muscles to support their heads.

Even if you sleep a lot all night, you still feel sleepy during the day.

3. When I am about to fall asleep or wake up, I have symptoms of being temporarily unable to speak or being unable to move all over my body.

4. More than half of those who are sleepy will be accompanied by symptoms of memory loss or memory interruption. At these stages, people with drowsiness will be at a loss, babble or scribble, and put things wrong or bump into things when walking or driving. The typical symptom is that they can't control their behavior at these stages and don't remember what happened later.

If you have one or more of the above symptoms, you should go to a professional treatment institution to avoid adverse consequences.
