Keeping track of your sleep may not be a top priority, but getting enough sleep is essential for health general organism. You may not realize it, but the amount of sleep can affect everything, weight, metabolism, brain function, and mood.

The time you go to sleep, however, tends to vary depending on your social life, working hours, family obligations, or just when you start feeling tired. Even if this changes every night, the alarm clock always rings at the same time in the morning, for this reason it is important to sleep a specific amount of hours in order to function at its best the next day.


How much sleep do you need?

La amount of sleep what you need changes over the course of your life; a newborn baby may need up to 17 hours of sleep each day, while an older adult can get by on just 7 hours of sleep a night. 

According l 'American Academy of Pediatrics and CDC, these are the general sleep guidelines divided by different age groups:

  • birth at 3 months: 14 to 17 hours
  • 4 to 11 months: 12 to 16 hours
  • 1 to 2 years: 11 to 14 hours
  • 3 to 5 years: 10 to 13 hours
  • 6 to 12 years: 9 to 12 hours
  • 13 to 18 years: 8 to 10 hours
  • 18 to 64 years: 7 to 9 hours
  • 65 years and over: 7 to 8 hours

Obviously, the needs related to sleep and rest can be different, even within the same age group. Some people may need at least 9 hours of sleep a night to feel well rested, while others in the same age group may need as much as 7 hours.

La sleep deprivation it's a real thing for many people, especially with increasing work stress. Too little sleep can affect many of your body's systems and restorative functions.

You may also sleep too little due to:

  • insomnia
  • obstructive sleep apnea
  • chronic pain

Some signs that you may not be getting enough sleep are:

  • you are sleepy during the day
  • you are more irritable or moody
  • you are less productive and focused
  • your appetite increased
  • your judgment and decision making are not what they usually are

What are the stages of sleep?

Hours of sleep are based on:

  • your alarm clock
  • five or six 90-minute sleep cycles
  • 15 minutes to fall asleep

When you fall asleep, your brain and body go through several cycles. Each cycle comprises four distinct phases. The first three stages are part of sleeping with non-rapid eye movement (NREM) and the last stage is the REM sleep (Rapid Eye Movement).

NREM stages were classified as stages 1, 2, 3, 4 and REM. They are now generally classified like this:

  • N1 (formerly phase 1): this is the first phase of sleep and the period between waking and falling asleep
  • N2 (formerly stage 2): The onset of sleep begins at this stage when you become unaware of your surroundings. The body temperature drops slightly and breathing and heart rate become regular
  • N3 (formerly stages 3 and 4): This is the deepest, most restorative sleep stage during which breathing slows, blood pressure drops, muscles relax, hormones are released, healing occurs, and the body is re-energized
  • REM: This is the final stage of the sleep cycle. It takes up about 25% of the sleep cycle. This is when your brain is most active and dreams occur. During this phase, your eyes move back and forth rapidly under the lids. REM sleep helps improve your mental and physical performance when you wake up

It takes, on average, about 90 minutes to run each cycle. If you can complete five cycles a night, you would sleep 7,5 hours a night. Six full cycles are about 9 hours of sleep. Ideally, you should wake up at the end of a sleep cycle instead of in the middle of it, to feel more refreshed and energetic.
