One work which we are doing every day i.e sleep. We require almost 6 hours to recharge ourselves for the next day.

As we all know sleep is one of the most important activities for good health. In that 6 hour duration, our body and head not relax, but also It does many important tasks like repairing our muscles, bone growth, manage hormones and sorting the memories, etc.

Our sleep works on one specific sort of sleep cycle. Each cycle takes 90min to complete.  In 7-8hours duration, 6 to 7 times our body experiences that specific type of sleep cycle.

Basically, there are two types of sleep.

1) REM: Rapid eye movement sleep 

2) Non REM Sleep.

Stage 1:

Stage 1 starts with non-rem sleep. When we begin to sleep. It remains for a few minutes.

 In this stage, our body starts relaxing. Our heartbeats become relax and alpha & theta waves generate in our brain.

Stage 2:

This stage also comes under non-rem sleep. In this stage, we start entering into a deep sleep. It lasts up to 25min to 30min.

In this stage, our body gets more relaxed. Heartbeat and breathing get slowed down. Production of alpha & theta waves spike up and our body temperature gets back to normal. 

Stage 3:

The final stage of non-rem sleep. We are in the deepest stage of sleep. 

In this stage repairing and maintenance work happens. Like tissue repair, strengthing of the immune system, cell regenerations, and other health-improving tasks happens in this stage. 

Stage 4: 

This stage is known as REM sleep. It is vice versa of non-rem sleep. Dreaming, sleepwalking, paralyzed state, etc happen in this stage. This stage lasts up to 10min to 60min.

In this stage eye movements happen rapidly, heart rate increases constantly. Unconscious brain activities begin in this stage. 

 Important tip:

Sleep is a passive process. It plays an important role in body healing, memory consolidation, and segregation. But due to the consumption of alcohol, caffeine we disturb REM as well as non REM sleep.

As such, this article gives you a good overview of how our sleep cycle works throughout the night as well as what will happen if we consume caffeine and alcohol before going to bed.
