Weight Gain
Another significant consequence of insufficient sleep is its impact on weight. The survey found that:
- 26% of sleep-deprived individuals were overweight
- 32% experienced bloating
“During sleep, the body balances hormones like ghrelin and leptin, which control hunger and satiety,” explained Artis.
Without enough rest, ghrelin levels rise, increasing hunger, while leptin levels drop, reducing the feeling of fullness. “This hormonal imbalance triggers overeating, particularly cravings for high-calorie, sugary foods,” she said.
Additionally, Artis noted that men and women may gain weight differently due to sleep deprivation. “Women are more likely to store fat in the hips and thighs due to hormonal changes, while men may accumulate more abdominal fat due to decreased testosterone levels,” she explained.
Imbalance in Body Temperature
Another lesser-known effect of poor sleep is temperature regulation issues, particularly cold hands and feet. “Body temperature is also under circadian control,” Artis noted. “Sleep loss can impair the body’s ability to manage and adjust its internal temperature, leading to fluctuations and discomfort in the hands and extremities.”
Constipation
Emerging research suggests that sleep deprivation may contribute to digestive issues, including constipation. One study found that people with a history of poor sleep had a significantly higher risk of developing constipation, highlighting the vital role sleep plays in gastrointestinal health.
How Much Sleep Do We Really Need?
The amount of sleep a person requires varies based on multiple factors. “A healthy adult usually needs around 7 to 9 hours of sleep,” the NHS advises.
However, individual needs depend on age, health, and lifestyle. Children, teenagers, and babies require significantly more sleep to support growth and development. Newborns, for instance, may sleep anywhere between 8 to 16 hours per day.
Prioritizing Sleep for Long-Term Health
Lack of sleep does more than leave you feeling fatigued—it can impact nearly every aspect of your body, from your skin and nails to digestion and weight management. Understanding these effects highlights the importance of prioritizing good sleep habits for overall well-being.
