Sleep. We all need it, but it seems that many of us don't get enough sleep. Some struggle to get to sleep, some struggle to stay asleep, and still others struggle with how much sleep, or how little sleep, they get. I am in the group that gets too little sleep.
Why is sleep so important? According to The Harvard Women's Health Watch, here are 6 reasons to get plenty of sleep.
1. Learning and Memory: Sleep helps the brain commit new information to memory through a process called memory consolidation.
2. 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.
3. Safety: Sleep debt contributes to a greater tendency to fall asleep during the daytime. These lapses may cause falls and other mistakes.
4. 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.
5. Cardiovascular Health: Serious sleep disorders have been linked to hypertension, increased stress hormone levels, and irregular heartbeat.
6. Disease: Sleep deprivation alters immune function, including the activity of the body's killer cells. Keeping up with sleep may also help fight cancer.
The amount of sleep that you need varies from person to person, but a good rule of thumb is between 7 and 8 hours a night.
In my case, I have noticed a difference when I get more or less sleep. Over the summer when the kids were off school I got into the habit of sleeping until 6am and generally I would go to bed around 10pm. So that was a good 8 hours of sleep. But now that the kids are back in school, I get up at 4am, but even though I try to get to bed earlier, I often don't get to bed until 10pm. Because of this, I see changes in myself. I am tired during the day more often for sure, but I also notice that I have been gaining weight, not much, but it's also harder to lose. This, I believe, is due to the increase of cortisol levels. To correct this, I just have to once again find the balance.
I encourage you to take a look at your sleep habits and see if you are getting enough sleep. Could you adjust your routines somewhere to get in an extra hour of sleep? Your body will thank you!
