Getting less than seven hours of sleep can impact far more than just your energy levels—it may affect your entire body. According to research from sleep company Simba, sleep deprivation can trigger several physical problems.
Experts say poor sleep raises cortisol, the body’s stress hormone, which may worsen skin conditions like eczema and psoriasis while causing redness, itching, and irritation. Reduced blood flow during sleep deprivation can also leave skin looking dull and tired.
The study found that many people who sleep too little report sensitive skin, brittle nails, bloating, and weight gain. Lack of rest disrupts hunger hormones like ghrelin and leptin, increasing cravings and overeating—especially sugary foods.
Sleep deprivation may also affect body temperature regulation, leading to cold hands and feet, while other studies suggest it can raise the risk of constipation and digestive issues.
Health experts recommend adults get 7 to 9 hours of sleep per night, though needs vary by age and lifestyle. Quality sleep remains essential for physical health, appearance, and overall well-being.
