A nap is a midday rest habit that helps the body quickly and effectively restore energy during a long working day, especially for people who regularly work in harsh weather, do heavy labor or work under pressure.
Regular, sufficient naps may provide positive health effects such as:
- Helps improve concentration and restore energy. According to scientific studies, the brain can concentrate effectively with optimal energy for only about 3 – 4 hours, so a midday nap can be a lifesaver by providing extra energy for afternoon activities.
- Relaxes the eyes and reduces strain. If the eyes work continuously, this creates considerable pressure on the eyeballs and retina, affecting vision and refractive errors. A short nap helps minimize the eye diseases you may encounter.
- Helps prevent memory decline. Every day, studying and working require the brain to operate at full capacity to receive and remember large amounts of information. If this happens continuously, the nervous system becomes overloaded and memory may decline. A midday nap gives the brain time to rest and restore energy for the next period of study and work.
- Helps reduce cardiovascular problems . Similar to the nervous system, the heart must work effectively and continuously to deliver blood to all parts of the body, especially the brain and limbs. A nap helps the body slow down so the heart can reduce its contraction rate, recover energy and work more effectively.
If a good night’s sleep should ideally last 8 hours, then a nap only needs 30 minutes – 1 hour to be optimal. Choose a quiet place with a comfortable room temperature and minimal disturbance so that the benefits of sleep can be maximized.
