I wanted to share some research I have been looking at concerning sleep and just how important it is. Many of us have grown up thinking that we can survive on very little sleep and are almost proud of the all nighter's we have pulled during highschool or college to get last minute assignments done on time, out having fun or other things. But did you know that having chronic lack of sleep can actually cause you to become quite sick over time?
In today's modern society where we have electricity, nice warm houses and plenty of entertainment (and work) to keep us up to all hours of the night, it is very difficult to maintain a healthy sleep pattern or go to bed early enough to actually be of use to our bodies. Sleeping on average from 9pm till 6 or 7am (8 or 9 hours sleep) would actually be the optimal time for most people to sleep, but because the evenings are often so packed with activity and it is so often the final time of the evening when you get any relax time for themselves or time without kids most people stay up way too late.
Here is an article that the Harvard Medical School has written about sleep:
Importance of Sleep : Six reasons not to scrimp on sleep January 2006 A recent survey found that more people are sleeping less than six hours a night, and sleep difficulties visit 75% of us at least a few nights per week. A short-lived bout of insomnia is generally nothing to worry about. The bigger concern is chronic sleep loss, which can contribute to health problems such as weight gain, high blood pressure, and a decrease in the immune system’s power, reports the Harvard Women’s Health Watch.
While more research is needed to explore the links between chronic sleep loss and health, it’s safe to say that sleep is too important to shortchange.
The Harvard Women’s Health Watch suggests six reasons to get enough sleep:
- Learning and memory: Sleep helps the brain commit new information to memory through a process called memory consolidation. In studies, people who’d slept after learning a task did better on tests later.
- Metabolism and weight: Chronic sleep deprivation may cause weight gain by affecting the way our bodies process and store carbohydrates, and by altering levels of hormones that affect our appetite.
- Safety: Sleep debt contributes to a greater tendency to fall asleep during the daytime. These lapses may cause falls and mistakes such as medical errors, air traffic mishaps, and road accidents.
- Mood: Sleep loss may result in irritability, impatience, inability to concentrate, and moodiness. Too little sleep can also leave you too tired to do the things you like to do.
- Cardiovascular health: Serious sleep disorders have been linked to hypertension, increased stress hormone levels, and irregular heartbeat.
- Disease: Sleep deprivation alters immune function, including the activity of the body’s killer cells. Keeping up with sleep may also help fight cancer.
