We all know that having a late night often results in feeling a bit tired the next day, however new studies have indicated that by staying up late watching your favourite show back to back, you are actually impacting upon the way in which your body metabolizes cholesterol!
Our body is quite an amazing thing, with different genes that have very specific roles and responsibilities when it comes to running and maintaining our body. Several studies conducted at the University of Helsinki, have indicated that the gene responsible for cholesterol regulation, is less active in people who are sleep deprived people. This includes both short term and long term sleep deprivation!
What these studies indicated was that the good cholesterol, high-density lipoprotein (HDL), that helps flush the bad cholesterol, low-density lipoprotein (LDL), out of the arterial walls, is actually lower in people who are sleep deprived. This means that opting for a late night is actually impacting on your health in more ways than just leaving you feeling a little sluggish!
Even more interesting is just how quickly missing out on sleep starts to impact on your physical health. The instant effect (after just one night of little sleep) is drowsiness, impaired cognitive function, lack of energy and possible mood swings. However after just one week of continued lack of sleep (sleeping less than you need each night) your immune system response is reduced, your metabolism is affected and you start altering your body’s HDL to LDL ratio!
So getting a good night’s sleep is even more important than just looking and feeling your best, your long term health depends on it!
