“During sleep, the body balances hormones like ghrelin and leptin, which control hunger and satiety,” Ms. Artis explained. Without adequate rest, ghrelin levels spike, making people feel hungrier, while leptin levels decrease, reducing the feeling of fullness.
“This hormonal imbalance triggers overeating, especially cravings for high-calorie sugary foods.”
According to Ms. Artis, sleep deprivation may also play a role in the different ways men and women gain weight. “Women are more likely to see increased fat in the hips and thighs due to hormonal changes, while men may notice more abdominal fat due to decreased testosterone levels,” she said.
Another unexpected effect of insufficient sleep is having cold hands and feet. “Body temperature is also 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 explained.
Another study investigated the potential relationship between sleep disturbances and various types of constipation in patients. The findings suggested that people with a history of insufficient sleep had a significantly higher risk of developing constipation, highlighting the importance of sleep quality in gastrointestinal health. The amount of sleep a person needs varies based on multiple factors.
“A healthy adult usually needs around 7 to 9 hours of sleep,” the NHS advises. However, individual requirements differ depending on factors such as age, health, and personal circumstances. Some people naturally require more sleep than others.
Teenagers, children, and babies need additional rest to support their growth, with newborns sleeping anywhere from 8 to 16 hours a day. Source: Brightside
