3 Reasons Why Good Sleep Is Important
1. Good Sleep Can Improve Concentration and Productivity
Sleep is important for various aspects of brain function. This includes cognition, concentration, productivity and performance. All of these are negatively affected by sleep deprivation. A study on medical interns provides a good example. Interns on a traditional schedule with extended work hours of more than 24 hours made 36% more serious medical errors than interns on a schedule that allowed more sleep. Another study found that short sleep can negatively impact some aspects of brain function to a similar degree as alcohol intoxication. On the other hand, good sleep has been shown to improve problem-solving skills and enhance memory performance of both children and adults.
2. Poor Sleep Can Make You Fat
Poor sleep is strongly linked to weight gain. People with short sleep duration tend to weigh significantly more than those who get adequate sleep. In fact, short sleep duration is one of the strongest risk factors for obesity. In one extensive review study, children and adults with short sleep duration were 89% and 55% more likely to become obese, respectively.
The effect of sleep on weight gain is believed to be mediated by numerous factors, including hormones and motivation to exercise. If you’re trying to lose weight, getting quality sleep is absolutely crucial.
3. Sleep Affects Emotions and Social Interactions
Sleep loss reduces your ability to interact socially. Several studies confirmed this using emotional facial recognition tests. One study found that people who had not slept had a reduced ability to recognise expressions of anger and happiness. Researchers believe that poor sleep affects your ability to recognise important social cues and process emotional information.
