5 Reasons Why Good Quality Sleep Is Beneficial To Your Health & Fitness
Often we hear that sufficient good quality sleep is vital for our physical and mental well-being. But, we often focus on our diet and physical activity when trying to improve our health and fitness and ignore sleep. Though sufficient good quality sleep is a must for our body to rest and recover. And is equally important for us to stay healthy and fit.
In 24 hours of a day, we try to accomplish as many tasks as possible. But, when we don’t find enough time to complete our tasks, we tend to sacrifice sleep. Insufficient good quality sleep or poor sleep has an adverse impact on your hormones; which can lead to weight gain, mental stress, depression, anxiety, and other life-threatening diseases like cardiovascular diseases, and type 2 diabetes.
As per sleep experts, 7-8 hours of good quality sleep each night is best to achieve optimal health benefits. Sufficient good quality sleep allows your body to take the complete rest that is required by it to recover from the hard work of the day and be ready for the task that needs to be accomplished the following day.
Insufficient good quality sleep also affects your social well-being, as it can make you irritable and moody. Plus, it can reduce energy levels and motivation to perform your daily tasks, ruining your productivity.
Older adults are more resistant to the effects of sleep deprivation. But young adults and children don’t have the same level of resistance and may become hyperactive or rebellious.
So, here are 5 reasons why sleep is good for your health and fitness…
1. Prevents Excess Weight Gain
Sufficient good quality sleep helps your body to prevent excess weight gain by stopping you from overeating and it allows your body to balance hormones, Ghrelin, and Leptin. These hormones control your hunger. Ghrelin, also called the “hunger hormone”, stimulates appetite and increases the intake of food; whereas Leptin inhibits hunger. Ghrelin promotes the storage of fat whereas leptin helps in reducing fat storage.
Insufficient sleep disrupts your body from using insulin properly. Your body becomes insulin resistant which allows fat to circulate in your blood resulting in the generation of more insulin. This excess insulin is stored as fat in your body
Insufficient good quality sleep also results in increasing your stress level. When your stress levels increase, your body starts producing more Cortisol; which forces your body to store more calories as fat.
2. Reduces Risk of Cardiovascular Diseases
When you are asleep, your blood pressure level lowers down which results in giving your heart and blood vessels a rest. Insufficient good quality sleep or poor quality sleep is known to increase the stress level and increase anxiety; which can increase your blood pressure level and cholesterol levels. High blood pressure and excess cholesterol level in your body can lead to serious life-threatening diseases like hypertension, coronary heart diseases, and diabetes mellitus.
In addition to diet control and physical activity, doctors recommend that 7-8 hours of good quality sleep daily is vital to reduce the risk of developing many cardiovascular diseases.
3. Improved Concentration and Productivity
Another reason why sleep is good for your health is because it helps to improve your brain health. An adequate amount of good quality sleep can boost levels of your concentration, problem-solving skills, and productivity.
Insufficient good quality sleep or poor sleep can impair the functioning of your brain, make you tired mentally, and reduce the level of alertness and concentration. Sleep deprivation can throw clarity of thoughts out for a toss and you won’t be able to make the simplest of decisions, and forget making complex ones because of which your productivity suffers.
The deep sleep stage is essential for your brain to consolidate memories and link stories of the day. While your body is resting, your brain is at work in consolidating feelings, memories, events, thoughts, and other sensory inputs gathered during the day and preparing for new inputs, memories, thoughts, events to be registered the following day.
4. Boosts the Immune System
Your immune system helps you to fight infection by identifying harmful viruses and bacteria and getting rid of them. Another health benefit of adequate good quality sleep each night is that it can help you improve your immune system and help fight infections like the common cold.
As per some studies, even a small reduction in the amount of required sleep can weaken your immune system. It found that people who sleep less than 7 hours per night are 3 times more likely to catch a cold than those who sleep a minimum of 8 hours per night.
Sleep deprivation weakens your immune system and your body is not able to fight infections with the same strength or pace. Due to a weak immune system, you may fall sick more often.
5. Helps to Reduce Inflammation
Insufficient good quality sleep increases stress hormones and anxiety which raises the level of inflammation in your body resulting in making your body prone to developing cardiovascular diseases, even cancer, and diabetes.
Also, inadequate good quality sleep or poor sleep has a major undesirable impact on your body as your body may develop inflammation due to cell damage. It may lead to recurring inflammatory bowel diseases due to inflammation of your digestive tract.
Sufficient good quality sleep is good for your health and fitness because of several reasons:
- it boosts your immune system to fight infections
- helps you to avoid weight gain
- helps you to avoid developing life-threatening cardiovascular diseases
- improves concentration
- helps in reducing stress levels and inflammation
- and getting rid of anxiety
Sufficient good quality sleep helps you to rest and recover from the tiring efforts of the day which is vital for being productive the next day.
