Your may have read some headlines recently, discussing how lack of sleep can cause you to gain weight. You may even have experienced this first hand. I know when I do not sleep well, I usually overeat the next day. I had assumed this was my bodies way of getting much needed extra energy. I assumed it was something that specific to me, not necessarily driven by any known biological mechanism of action.
It turns out there is a biological reason that we eat more when we have not slept. Through knowledge gained from research studies on why sleep is so important, it has been shown that many important functions occur while we sleep. The body and brain repairs itself while we sleep. Most of us have always assumed this, but many of us would never imagine that lack of sleep can make us fat!
Sleep deprivation, even if only for a few days; can wreck havoc on our hormone system. It can cause cortisol to rise in the evening, when it should be declining. This rise in cortisol can contribute to diabetes and obesity as it promotes fat storage. Thyroid function can also be affected by lack of sleep.
But how can sleep actually make us fat? In addition to the cortisol rise mentioned above, sleep deprivation affects the appetite regulatory hormones leptin and ghrelin. These hormones play an important role in helping to regulate our appetite through signalling when we are full and when we are hungry. Lack if sleep causes them to rise and fall inappropriately, encouraging you to consume more calories than you actually require.
Additionally, lack of sleep has been shown to also decrease glucose sensitivity by almost 30%. This means that the food you eat will not be utilized as efficiently and will be more likely to be stored as fat. Such a response implies that chronic sleep deprivation may cause an increased chance of developing diabetes and obesity.
Menopausal sleep deprivation can not only add to the weight gain and fatigue of menopause, it can also increase your risk of diabetes and heart disease. If you are being told by your medical provider that your glucose, cholesterol and blood pressure are becoming higher than normal; your sleep patterns as well as diet may be the reason.
It is important to work on your sleep habits in order to minimize the effect menopause may be having on your health. Work on getting plenty of exercise, decrease caffeine, learn to relax and maybe meditate to decrease stress. Talk to your provider about help with sleep and any medical conditions other than menopause which may be contributing to lack of sleep.
Most importantly, set a schedule for sleep and stick to it! Work on not allowing the phone, your computer, or TV watching interfere with your bedtime.
