Changes in weather, especially eating cold foods in a chilly climate, can commonly lead to colds. But did you know that not sleeping properly can also make you prone to colds? Studies show that people who sleep less than 7 hours a day are more likely to catch a cold.
Additionally, insufficient sleep affects brain function. In today's fast-paced tech-driven world, sleep often gets neglected. Global health organizations recommend at least 8 hours of sleep for good health.
Both too much and too little sleep are harmful. Research indicates that those who sleep less are more likely to suffer from diabetes, high blood pressure, heart diseases, and obesity.
Interestingly, one survey found that people who sleep less than seven hours are more likely to catch a cold than those who sleep more. Lack of sleep increases the hormone ghrelin, which stimulates hunger, and decreases leptin, the hormone that signals fullness, leading to overeating and obesity.
Researchers also note that insufficient sleep impacts brain function. Waste cells accumulate in the brain each day, which get cleared during sleep. Without enough sleep, these waste cells accumulate and affect brain performance.
