Sleep is an essential part of our physical and mental health, providing our bodies with the necessary rest and energy to function properly. When we don't get enough sleep, our bodies and minds become depleted, leading to feeling emotionally drained. After a good night's sleep, our bodies have the opportunity to recharge and repair, leading to improved mental clarity and emotional balance. Sleep also helps to regulate our hormones, which can affect our moods. Additionally, during sleep our brains have the opportunity to process and make sense of the day's events, leading to a better outlook on life. All of these factors contribute to why we feel better emotionally after sleeping.
