Getting enough sleep is important for overall health, but stress, insomnia, and other disruptions can make it difficult to reach the commonly recommended amount. A survey of 2,175 UK adults conducted by sleep technology company Simba explored sleep habits and reported physical effects associated with insufficient rest. The findings highlighted possible changes involving hormones, skin, weight, and other aspects of health.

Sleep deprivation may affect the skin in particular, with reported issues including increased sensitivity, eczema, psoriasis, and a duller complexion. The survey also found that some people experiencing insufficient sleep reported brittle nails. These effects may be connected to the body’s nighttime repair processes and changes in stress-related hormones.

Insufficient sleep has also been associated with increased hunger, bloating, and weight-related concerns. Sleep disruption can affect hormones involved in appetite and fullness, while research has also suggested possible links between poor sleep, body-temperature regulation, and digestive problems such as constipation. However, individual experiences can vary, and these associations do not mean that sleep loss is the sole cause of these conditions.

The amount of sleep people need depends on age and individual circumstances. The NHS generally recommends around 7–9 hours for healthy adults, while children and teenagers typically need more. Maintaining a consistent sleep routine and allowing enough time for rest can support the body’s normal recovery and help promote overall well-being.
