Why do sleep problems affect mood more than we expect?

[Shree]

Have you seen how even one bad night of sleep can make emotions harder to manage the next day? What sleep habits actually help stabilize your mood consistently?

Sleep problems affect mood because sleep is when the brain restores emotional balance and processes stress. Without enough rest, regulation systems don’t work properly, making people more sensitive, irritable, and less able to cope. Even small issues can feel much bigger and harder to manage.
