Why is Sleep so Important?

Updated: Dec 23, 2021

Importance of sleep

According to SingHealth in 2018, it was found that 15% of Singaporeans are suffering from insomnia. Sleep is one of the most underrated and neglected aspects when it comes to improving our health. Often, when it comes to trying to be healthy, we will look into programming an exercise regime, planning out a healthy diet or even have a personal trainer do that for us. However, we tend to overlook one of the most important factors which is sleep. Many of us are probably guilty of that as we are often caught and tied up with our busy schedules causing us to not have adequate sleep. In this article, we will be sharing with you why it is important to have adequate sleep and the benefits that come along with adequate sleep.

1. Improved mood:

Studies have found that the lack of sleep often leads to us feeling fatigued and hard to concentrate the very next day. Consequently, this would leave us feeling more grumpy and irritable the very next day. In fact, our mood will also affect how much and how well we sleep ! Feelings of anxiety, stress and agitation can result in our body feeling aroused, awake and alert. All these may inadvertently disrupt your sleep quality and affect your mood.

2. Improved muscle recovery:

Adequate sleep helps in the regulation of hormones produced by the body. In particular, ample sleep will help regulate the release of growth hormones in the body. Human growth hormone is an essential hormone which helps in the muscle recovery process. This will help with our fitness goals such as building muscles in the gym.

3. Improved exercise performance:

With adequate amounts of sleep, this helps to improve one’s focus and concentration as well. With improved focus and concentration, this allows us to improve our exercise performance as we are better able to activate our muscles and focus on completing the exercise with optimal form with the guidance of a personal trainer. In addition, an ample amount of sleep will leave us feeling more refreshed and energetic the next day, which will boost our exercise performance as well !

4. Improved immune function:

The lack of sleep can affect one immune system in a negative way. During our sleep, our body releases antibodies that help to combat infection and inflammation. A lack of sleep may result in the decrease in production of these antibodies hence weakening our body’s immune system. This might result in us having a higher risk of falling sick when exposed to viruses such as the common cold.

In conclusion, there are many associated benefits with having adequate amounts of sleep. However, a very common question one might have is how much sleep do I need ? The National Sleep Foundation recommends that for healthy adults, we should get 7-9 hours of sleep per night. In addition, you want to ensure that you have good quality of sleep. Some characteristics of a good quality sleep includes being able to fall asleep within 30 minutes and waking up no more than once throughout the night.

So do remember to get at least 7 hours of sleep every night in conjunction to regular exercise for optimal health, growth and recovery.
