Sleep is an important part of our daily life cycle.  It gives the body the rest and time it needs to replenish the energy that it lost during the day.  It helps to make our bodies physically and mentally healthy and alert.

You need to have sufficient amounts of sleep everyday.  Sleep deprivation is one of the root causes of many health problems including depression, weight gain, diabetes and cardiovascular diseases.

Your body needs seven to nine hours of restful sleep every night.  Some of its health benefits include reduced stress, better physical and emotional health and a longer life.

When you lack sleep, your body does not fully recover the energy it expended several hours before.  It can cause fatigue and weaken your resistance to stress and disease causing organisms.  It also makes you irritable, sloppy and unproductive.

But there are times when you just find it difficult to sleep.  These could be triggered by worry, the foods you eat, caffeine or an event which require you to stay up late at night.

When this happens, you need to take herbs as natural sleeping aids to help you sleep easily.  They are a lot better than synthetic sleeping pills because they do not carry serious side effects.

Here are four herbs that can help to make you sleep easily:

1. Chamomile

Chamomile is a flowering plant which has been used as tea for centuries.  Chamomile has many health advantages, but its most popular property is its relaxing effect and ability to induce sleep.

The U.S. National Institute for Health advises that pregnant women should not consume chamomile because it can stimulate uterine contraction.

2. Kava Kava

Kava kava is a shrub native to the Pacific islands.  It has been used for hundreds of years both as a ceremonial drink and as sedative and analgesic.  This plant is also known for its relaxing and mood enhancing effects.  Many people use it to treat insomnia, anxiety and other nervous disorders.

Kava kava is said to have a rare but potential risk to your liver.  Use it under the close supervision of a health professional.

3. Passion Flower

Passion flower is a plant native to North, Central and South America.  Native Americans used this plant as an herbal sleep aid for its sedative effect.  It is also able to provide a relaxing effect that helps to alleviates anxiety.

4. Valerian Root

Valerian is a perennial herb native to Europe which is used as a natural sleeping aid for its sedative and calming effects.  It is also used to combat stress, anxiety, menstrual cramps, headaches, muscle spasms, and stress-related digestive disorders.

These are the four top herbs that you can use as natural sleep aids.  Use them for a relaxed, restful sleep, and get refreshed each morning after.
