Just like the saying "Sleep is medicine," adequate sleep duration is a shortcut to good health. However, busy modern people often find it difficult to stick to their sleep schedule. Nevertheless, if one consciously does not get close to 8 hours of sleep, various diseases and health problems can arise. Based on domestic and international health data, this article introduces diseases that can occur due to lack of sleep.

1. Cardiovascular disease

Lack of sleep is a major risk factor for cardiovascular disease. During sleep, blood pressure drops by about 10% compared to when awake, but if sleep is insufficient, the sympathetic nervous system remains continuously activated, increasing cardiovascular risk. This also raises the risk of hypertension, heart attack, and stroke.

2. Obesity

Obesity is a shortcut to sleep deprivation. When we can't sleep well, it is difficult to avoid weight gain. Sleep deprivation disrupts the balance of hormones like leptin and ghrelin that regulate appetite, leading to overeating and especially increasing cravings for high-calorie foods.

3. Diabetes mellitus

Lack of sleep increases insulin resistance and makes blood sugar control more difficult, raising the risk of diabetes. According to a study published in March by a Swedish research team, people who sleep only 3 to 5 hours a day have up to a 41% higher risk of type 2 diabetes compared to those who sleep 7 to 8 hours.

4. Depression and Anxiety

Lack of sleep can lead to mental health issues such as depression, anxiety, and stress. Getting enough restful sleep allows us to recover both physically and mentally. REM sleep has the function of processing emotions accumulated during the day. Therefore, insufficient or disrupted sleep can lead to depression. According to Seoul National University health data, more than half of insomnia patients report depression or anxiety disorders, and two out of three depression patients report insomnia.

5. Decreased immunity

Chronic sleep deprivation weakens the immune system, making it more susceptible to infectious diseases such as colds. It can also reduce the effectiveness of vaccinations. When our body lacks sleep, the immune system becomes weakened, increasing vulnerability to infections. According to research, insufficient sleep raises the likelihood of catching a cold and diminishes the effectiveness of vaccines.
