sleeping-patterns-affect-weight-lossSleep is a natural way of restoring your body’s energy. It is a complex and important activity/function of a body. Most people have had problems sleeping at some time or another. If you don’t get enough sleep, or the right sort of sleep, your body and mind won’t work as well as they should. The normal sleep requirement varies from person to person and there is no health benefit in forcing yourself to have more sleep than you need. We all need light sleep, deep sleep and dreaming sleep to feel refreshed when we wake up.

Types of Sleep and Sleeping Patterns:

Everyone’s sleeping patterns are different. Some people sleep more than eight hours a day – others need as little as five. Generally, the need for sleep decrease as we get older. Both the number of hours you sleep and the structure of the sleep you get are important. There are two main types of sleep,

Rapid Eye Movement (REM) sleep: During REM sleep, your eyes flicker rapidly behind closed lids, your body temperature is slightly raised, the heart beats faster and breathing is irregular. REM sleep is often described as dreaming sleep. You are likely to have four or five periods of REM sleep during a night. Most of it occurs during the last third of your sleeping time.

Non-Rapid Eye Movement (non-REM) sleep: There are four stages of non-REM sleep ranging from light sleep to deep sleep. Stages 1 and 2 are the light sleep stages. Your muscles begin to relax, heartbeat is regular, body temperature slightly drops and sleep walking is possible at this stage. You can still be woken easily, for example, if you hear a door slam or someone calls your name or shakes you.

Stages 3 and 4 of non-REM sleep are the deep sleep stages. During these stages your blood pressure drops, your body is inactive and it is difficult to be woken up. Most of the deep non-REM sleep is in the first part of the night.

Dreams occurring at this time are usually snapshots, incomplete and may not make sense to you.

In a normal sleep cycle, non-REM and REM sleep alternate throughout the night. Sleep begins with about 80 minutes of non-REM sleep followed by about 10 minutes of REM sleep. This cycle is repeated three to six times per night. As the night progresses there is less deep sleep and more REM sleep per cycle.
