As kids, many of us were forced to get afternoon naps. That’s because children require more sleep than adults, up to 15 hours a day for infants. Sleep at this age is essential for physical and mental growth, attention, behavior, learning, and memory.

That’s why a consistent sleep schedule is critical for staying healthy and productive during the day. Keep reading for our top eight reasons for getting a good night’s sleep.

Top 8 Reasons Why Sleep Is Crucial For Good Health

  1. More Sleep Can Boost Concentration and Productivity – Getting enough sleep is critical for our overall cognitive performance. That includes concentration, attention, memory, learning, and performance. A study shows that doctors suffering from sleep deprivation are a lot more likely to commit medical errors at their workplace.

On the other hand, having good sleep shows that children, teens, and adults alike tend to perform better at school and university. Overall, having a good night’s sleep can make you more motivated and productive during the following day at work.

  1. Sleep Can Improve Your Athletic Performance – When we sleep, our body regenerates the energies expended during the day and mobilizes protein to build muscle, hormones, and other crucial compounds. Getting enough sleep is as important for weight loss and sports as are having a nutritious diet and ensuring an optimal calorie balance. It will provide you with more energy, better muscle coordination, more motivation, and better overall athletic performance.
  1. Boosts Your Immune System – Sleep is the time when the body regenerates itself and bolsters the immune system. That’s when we produce the so-called cytokines. The latter are special proteins that mediate the immune response and fight off infections and inflammation. 

While how exactly sleep promotes immunity is yet to be unveiled, numerous studies investigate the relationship. Sleep is especially important for our immunity when we are sick. That’s why we instinctively tend to sleep more when feeling unwell.

  1. Keeps Your Heart Healthier – Getting a good night’s sleep can help regulate your blood pressure. The latter is a significant risk factor for heart diseases. Overall, while we sleep, our heart rate tends to go lower, which decreases the work of our heart. However, studies show that oversleeping also has adverse effects on the heart so go for optimal, the most optimal 7-9 hours of sleep.

  1. Poor Sleep Is Linked to Inflammation – Sleep deprivation can contribute to various health issues because of its overburdening effects on our metabolism. Studies show that poor sleep is associated with disorders, such as inflammatory bowel diseases.

Sleep is also intricately linked to the sympathetic nervous system and the hypothalamus-pituitary-adrenal gland axis. It has a significant role in the regulation of stress and its hormones. Therefore, poor sleep can lead to inadequate responses to stress and contribute to inflammation.

Overall, if you’re looking to improve your overall health and wellness, start by ensuring you get at least eight hours of sleep every night.

  1. Sleep Deprivation Can Contribute to Depression – Apart from its various effects on our physical health and wellbeing, poor sleep can also affect our mental health. More studies nowadays show that depression and anxiety disorders are more common in people with poor sleep quality.

On the other hand, people who have insomnia or obstructive sleep apnea that tend to lead to poor sleeping habits also have a higher incidence of depression.

  1. Good Sleep Helps You Maintain A Healthy Weight – Getting more sleep doesn’t necessarily mean that you will start losing weight. Nonetheless, numerous studies identify sleep deprivation as a significant risk factor for weight gain and obesity. 

It’s because of its effects on appetite, hormonal balance, and thermoregulation. Poor sleep leads to higher production of the hormone ghrelin and reduces the levels of leptin. Ultimately, these effects stimulate our appetite, reduce the feeling of fullness, and tend to lead to overeating. 

Additionally, sleep deprivation can increase stress which also hurts weight management. Lastly, feeling tired from getting too little sleep the night before can make you less motivated to stick to your routine and hit the gym.

  1. Benefits Social and Emotional Intelligence – Perhaps not too unexpectedly, better sleeping patterns can promote better social and emotional intelligence. Studies show that adequate sleep helps us understand others’ emotions, provide support and demonstrate empathy. That’s probably because of how sleep contributes to better cognitive abilities, such as attention, concentration, and productivity.

Get good quality sleep to ensure a healthy body and mind.
