Is 4 hours of sleep okay and healthy?

The age of a person, from newborn to adulthood, is a tool that experts use to determine the recommended number of hours of sleep the person needs. It is recommended that:

  • Preschool-aged children, 3 to 5 years of age, receive 10 to 13 hours of sleep in a 24- hour period.
  • School-aged children, 6 to 12 years of age, receive 9 to 12 hours of sleep in a 24-hour period.
  • Teens, aged 13 to 18, receive 8 to 10 hours of sleep in a 24-hour period.
  • Adults, 18 and older, receive at least 7 hours of sleep in a 24-hour period.

Is 4 hours of sleep okay? Many believe that your body will adapt to a restrictive sleep schedule.

Nonetheless, there is no proof that this is true. Your body and mind rely on sleep to relax and reset after a long day. Maintaining a regular, healthy sleep schedule reduces the risk of depression, anxiety, hypertension, obstructive sleep apnea, psychosis, and other serious health complications.

How to sleep less and be more productive?

Can you sleep 4 hours at night and be more productive the next day? There is no cure for consistently obtaining less than 8 hours of sleep each night and having more energy the following morning. However, there are some things you can do to help learn essentially how to sleep 8 hours in 4 hours.

  • Cut out screen time. Are you wondering how to sleep less and have more energy? Cutting out screen time at least one hour before bedtime will help your body’s natural circadian rhythm and melatonin production, making it easier to fall asleep.
  • Create a dark sleeping space. Bright lights, TVs, and phone screens can impair your body’s natural ability to produce melatonin, the vitamin produced within your body to help you sleep.
  • Get an early morning workout. A light workout can increase blood flow to your brain, making you feel more awake.
  • Take a short nap. Many people have reported that taking a short 20 to 30-minute nap throughout the day has helped them learn how to sleep less but feel more energized.

Polysleep’s tips for a rejuvenating sleep!

At Polysleep, we understand that many wonder how to sleep 8 hours in 4 hours, as many are unable to do it due to circumstances out of their control.

We have put together the following tips to help each person achieve a rejuvenating sleep each night, whether you sleep 4 hours, the minimum recommended hours, or more.

Understanding how sleep works requires understanding the several phases of the sleep cycle. The sleep cycle is made up of 4 stages: awake, light sleep, deep sleep, and the REM cycle.

  • Phase 1 - awake. The awake phase is the time spent laying in bed just before falling asleep whether it be you laying in bed watching TV, scrolling through social media, or simply laying in the dark.
  • Phase 2 - light sleep. The second phase of the sleep cycle, light sleep, is accompanied by jerking and twitching motions and a decrease in breathing, heart rate, and body temperature. During the light sleep phase, people find it easy to wake.
  • Phase 3 - deep sleep. The third phase, deep sleep, makes waking up more difficult. When you do wake, you are often disoriented as it takes your mind a few minutes to catch up to your body. Deep sleep promotes muscle growth by increasing blood flow to the muscles, releasing growth hormones, and allowing tissue growth and cell repairs.
  • Phase 4 - REM sleep. Phase 4 of the sleep cycle causes your body to become immobile, stopping you from acting on very vivid dreams you may be experiencing. During REM sleep, respiration and heart rate increase while temperature regulation is turned off. The final phase of the sleep cycle is essential in benefiting learning, memory, and problem-solving.

Are you wondering how to sleep 8 hours in 4 hours? For some, it might be possible, while others find themselves feeling exhausted, fatigued, and unsure of what to do. It is important that you listen to the cues of your body and take proper measures to increase the number of hours of sleep you are getting each night.
