In fall, we "gain" an hour of sleep because of the end of daylight saving time. This means that the clocks are set back by one hour, so we have an extra hour to sleep. However, its important to note that the quality of sleep is just as important as the quantity. Chronic sleep deprivation can lead to a variety of negative health consequences, including weight gain and obesity. Lack of sleep can affect hormones that play a major role in the central control of appetite and energy, leading to increased cravings for energy-dense, high-carbohydrate foods. Additionally, sleep deprivation can decrease physical activity and negatively affect athletic performance, making it more difficult to achieve a calorie deficit for weight loss. Therefore, its important to prioritize getting enough high-quality sleep, regardless of whether we "gain" or "lose" an hour due to daylight saving time.
