6 Alarming Effects of Sleeping Less Than 7 Hours a Night, According to Recent Studies

Lack of sleep can affect more than just energy levels, potentially influencing skin health, nail strength, digestion, and weight. During rest, the body carries out important repair processes, including those that help maintain healthy skin. Research cited in the text also suggests a possible connection between insufficient sleep and brittle nails, with 15% of people reporting inadequate sleep experiencing this issue.

Sleep deprivation may also contribute to weight gain and bloating. The survey found that 26% of people who did not get enough sleep were overweight, while 32% experienced bloating. According to Ms. Artis, sleep helps regulate hormones such as ghrelin and leptin, which influence hunger and fullness. Poor sleep can disrupt this balance, potentially increasing appetite and cravings for high-calorie, sugary foods. She also noted that hormonal differences may influence where men and women tend to store body fat.

Other potential effects include cold hands and feet, as insufficient sleep can interfere with the body’s natural temperature regulation. Research has also suggested a link between sleep disturbances and an increased risk of constipation, highlighting the importance of rest for digestive health. According to the NHS, most healthy adults need around seven to nine hours of sleep each night, although individual needs vary. Children, teenagers, and babies generally require more sleep to support healthy growth and development.
