Skin Issues
The skin is one of the first areas to reflect the effects of sleep deprivation. “When sleep is compromised, reduced blood flow causes the skin to appear sallow and lack vibrancy, stripping it of its natural glow,” Ms. Artis explained.
Among individuals who slept inadequately, 24% reported heightened skin sensitivity, while others experienced eczema (16%), psoriasis (7%), and a dull complexion (10%). Ms. Artis further explained that, at night, the skin works to regenerate and repair itself. “During rest, blood flow increases, supporting the skin’s natural repair processes and promoting a healthy, radiant complexion.”
Weak or Fragile Nails
The study also found that 15% of those who had insufficient sleep reported brittle nails, indicating a possible connection between chronic sleep deprivation and weakened nail health. This could be linked to disruptions in the body’s natural repair processes, which are vital for maintaining strong and healthy nails.

Disruption in the Body’s Temperature Regulation
Another surprising effect of inadequate sleep is a disruption in the body’s temperature regulation. “Body temperature is under circadian control… Sleep loss can impair the body’s ability to manage and adjust its internal temperature, causing fluctuations and discomfort in the hands and other extremities,” Ms. Artis stated. This may explain why some people experience cold hands and feet when they are sleep-deprived.
