Sleep and mental health are irrevocably intertwined — too little or even too much can both be injurious to mental and physical health.

Yet it seems to be a state over which we have so little control.

Sleep has naturally fascinated researchers, who have asked how naps affect the brain, how winter affects our sleep and how to wake up feeling relaxed and refreshed.

Studies have also explored how lack of sleep affects our emotions and whether, if we cannot sleep, we become a different person after midnight.

So, here are 10 psychology studies from the members-only section of PsyBlog covering the latest sleep science.
