This has to be the first one to stand out. If just a few late nights at work can make you irritable, can you imagine what weeks and months of sleep deprivation can do to a body? Several studies have proven that lack of sleep contributes to high levels of Cortisol, also called the stress hormone. Stress and sleep are closely linked. While some people may suffer disturbed sleep patterns due to stress, others may become more stressed because of lack of sleep.
People who are sleep deprived suffer from a chronic sense of lethargy all the time. They are low on energy even when their daily nutrition needs are met adequately. You could fall asleep in the middle of the day even when you fight it. This can be dangerous, especially if feel the urge for ‘microsleep’ while on the road. Another noticeable sign is an inability to make quick decisions.
Just like a good night’s sleep keeps you happy and sprightly the next day, not getting enough sleep can play havoc with your days including messing up your emotional state. Yes, not sleeping enough can actually make you fall ill more often.
Your body’s response to infections gets impaired when the body does not get enough quality sleep. Your body produces infection-fighting antibodies during periods of sleep. This gets affected when you don’t get enough sleep, hence a lowering of our body’s immunity and defense mechanism.
They don’t just call it beauty sleep for nothing. Skin, being the largest organ of the body, is impacted greatly due to sleep deprivation. It is at night time that the body produces Collagen – which helps make the skin firmer. Not sleeping well could also make you prone to acne. So lookout for those skin breakouts as a possible sign of sleep deprivation.
Your regular margaritas hitting you harder than usual? Sleep deprivation is known to magnify the effects of alcohol on your body. So a person affected by sleep-deprivation will show greater levels of intoxication than someone who is well rested.
Even while we sleep at night, our brain is at work doing many tasks important for our well-being. One of them is to consolidate memory. So, you may have had a fun experience today but the only way you will remember every detail about it even a few years down the line is when your brain locks in the entire episode, seals it in for you to remember it for years to come. In addition to this, an exhausted body is unable to pay attention to an ongoing event like a rested body would.
Not getting enough sleep can mess with an appetite controlling hormone in the body called Leptin. You can thank this hormone for the feeling of satisfaction you get after a good meal. Leptin is also known as the satiety hormone and is released by the fat cells in the body. Lack of sleep affects the production of this hormone making the brain feel the need for more calories than normal. The result will be a perpetual feeling of hunger.
