Rest For Success: Why Is Sleep So Important?

A good night’s sleep is incredibly important for your health. In fact, it is just as important as eating healthily and exercising. The modern lifestyles we lead, however, is interfering with our natural sleep patterns and people are now sleeping less than they did in the past with sleep quality at an all time low. Here are top 5 reasons why having a good sleep is so important:

1. Poor Sleep Can Lead To Weight Gain

Horrifying but true! People with short sleep duration tend to weigh significantly more than those who get a good night’s sleep. In fact, short sleep duration is one of the strongest risk factors for obesity. Studies also show that sleep-deprived individuals have a bigger appetite and tend to eat more calories, as poor sleep affects hormones that regulate appetite. So, if you are trying to lose any Christmas weight, sleep is absolutely essential.

2. Good Sleep Can Improve Concentration & Productivity

Sleep is vital for various aspects of brain function including cognition, concentration, productivity and performance. All of these are negatively affected by sleep deprivation. A recent study found that short sleep can negatively impact some aspects of brain function to a similar degree as alcohol intoxication whereas on the other hand, good sleep has been shown to improve problem-solving skills and enhance memory performance.

3. Poor Sleepers Have Greater Health Problems

It is very well known that poor sleep quality can have a major effect on many health risk factors including a greater risk of heart disease and stroke. Sleeping less than 7-8 hours per night can also have an adverse effect on blood sugar which increases the risk of type 2 diabetes. In fact, sleep deprivation can cause prediabetes in healthy adults in as little as six days.

4. Good Sleep Improves Your Immune Function

Even a small loss of sleep has been shown to impair immune function. A recent study found that those who slept less than seven hours were almost three times more likely to develop a cold than those who slept eight hours or more, so make sure you get enough sleep every night to be able to healthily function in everyday life.

5. Poor Sleep Is LinkedIn To Depression

Mental health issues such as depression are strongly linked to poor sleep quality and sleeping disorders. It is estimated that 90% of people with depression complain about sleep quality. Sleep loss also reduces your ability to interact socially with poor sleep affecting your ability to recognise important social cues and process emotional information.
