Studies show that the consequences of not sleeping enough include a higher likelihood of obesity and overeating due to an imbalance in the hormones responsible for hunger and satiety.
How the Consequences of Not Sleeping Enough Increase Appetite
When the body does not receive sufficient hours of rest, the biological clock is disrupted and hormones, including insulin, are affected. This imbalance causes levels of “ghrelin,” the hormone responsible for hunger, to rise, while levels of “leptin,” which provides the feeling of fullness, decrease, prompting a person to consume more calories.
Data indicates that people who sleep fewer than seven hours per day spend more time eating—an average of 9 additional minutes daily compared to those who sleep longer.
Other Risks Associated with Sleep Deprivation
The impact of insufficient rest is not limited to weight gain; it extends to various health and psychological aspects:
- Daily Performance: Impaired concentration, memory, and alertness, which increases the risk of car accidents.
- Psychological and Sexual Health: An increased likelihood of depression and decreased libido, in addition to accelerated aging.
- Chronic Diseases: Increased risks of diabetes, hypertension, stroke, and heart problems such as heart failure and arrhythmia.
Other Health Causes of Overeating
Besides sleep disorders, there are medical and psychological factors that may increase the urge to eat:
- Glandular and Sugar Disorders: Hyperthyroidism, hypoglycemia, or diabetes can increase appetite.
- Dehydration: The brain may mistake extreme thirst for hunger.
- Medications and Psychological State: Some antihistamines cause hunger, and stress, depression, and psychological pressure can lead to eating large quantities of food.
- Obesity: A body struggling with excess weight becomes accustomed to high calorie amounts, which increases the feeling of hunger.
Guidelines to Improve Sleep Quality
To ensure an ideal rest period of 7 to 9 hours for adults, the following can be followed:
- Time Regulation: Set fixed sleep and wake-up times daily, including on weekends.
- Dietary Habits: Avoid caffeine (such as coffee and chocolate) and fatty or sugary foods 4 to 6 hours before bed.
- Physical Activity: Exercise regularly, but avoid strenuous workouts two hours before sleep.
- Sleep Environment: Use a comfortable mattress and keep the room quiet, dark, well-ventilated, and at a moderate temperature.
- Relaxation: Practice deep breathing, read, or take a warm bath, and avoid thinking about work or home worries when going to bed.
- Napping: Daytime naps should preferably not exceed 30-45 minutes in the afternoon.
