After a sleepless night, a lot of us have experienced waking up all groggy and grumpy with a heavy head. Chugging down cups of coffee and dragging ourselves to work, we lack the energy and enthusiasm to deal with the day’s challenges.
Scientists have linked high blood pressure to poor sleep. A recent study by Mayo Clinic monitored eight participants in 19-36 age bracket for 16 days. They found that when the participants experienced poor sleep, they also experienced an increase in blood pressure as a result. Experts say that people who get 5 hours or less sleep may have a greater risk of developing high blood pressure or worsening already high blood pressure.
Lack of sleep is also linked to a number of cardiovascular diseases. According to a study published in the European Heart journal, sleep deprivation increases the risk of developing and dying of coronary heart disease and stroke. But that doesn’t mean the more you sleep, the more your heart will be strengthened and the less risk of disease. An interesting finding in the study was that people who sleep more than the required number of hours also develop a risk of having heart problems.
Lack of sleep messes up the body sympathetic nervous system and hormonal balance which affect the performance of insulin producing cells, increasing the level of glucose and hence, making you prone to diabetes. A recent study published in the journal Diabetologia, studied 59,000 women in the 55 – 83 age bracket and found that chronic sleep deprivation increases the risk of developing diabetes.
Lack of sleep not only makes you fat and unhealthy but also dumbs you down by hampering your ability to learn new things and affecting your memory. A study conducted by researchers at the University of California showed that poor sleep leads to poor memory and forgetfulness.
5. Poor Immune System
Sleep deprivation suppresses the function of our immune system significantly. That means we are more likely to fall sick and catch a cold or flu. Once sick, your ability to fight sickness also depends on the quality of your sleep which is why we are often suggested to take rest when ill. Furthermore, sleep deprivation will make it longer for our body to respond to vaccines. So if you are getting a flu vaccine for instance, chances are you can still catch the flu because vaccine flu protection is significantly lowered due to inadequate rest.
Who knew the major culprit behind those extra layers of fat is lack of sleep. Multiple studies and researches have shown that sleep deprivation is the major cause of obesity and bad eating habits. Sleep is responsible for regulating your metabolism, repairing your muscles and rejuvenating your body. The growth hormone, produced only while you sleep, is responsible for the breakdown of fat, reducing fat storage and the building of muscles. So if you’re not sleeping enough you’re not giving the body enough chance to get rid of all the fat. According to research, sleep deprivation makes you lose 55% less fat than you would with adequate sleep even if you’re following a strict diet and fitness regime.
