Five Incredible Benefits Of Getting a Good Sleep

Dr Kausthub Desikachar shares the five most incredible benefits of getting quality sleep that may even leave you surprised. 

Healthy Heart

Getting quality enough sleep keeps your heart healthier. Sleep deprivation is linked with elevated blood pressure and certain chemicals linked with inflammation that can place added strain on your heart, leaving behind some critical heart disease.  

Improved Emotional Well-being, Productivity And Focus

Sleep plays a big part in keeping your brain energized and alert. Getting enough sleep helps to learn new stuff, focus, and be productive in whatever you do. A good night’s sleep can protect you from mood swings, depression, stress and anxiety, keeping you emotionally healthy. Long-term sleep deprivation also leads to risk factor like stroke. 

Stronger Immune System 

While you’re asleep, your body repairs the cells, regenerates, and recovers, keeping your immune system strong. The better your quality of sleep, the more your body fights off infection and keeps you healthy. 

Better Weight Management

Leptin and Ghrelin are the body’s hunger hormones that regulate and manage your appetite. When you’ve had a good sleep, you’re less hungry. Lack of sleep creates chaos with your hunger hormones and tempts you to eat unhealthy food, making you obese. Don’t ignore to get a good night’s sleep if you are on the lookout to lose those excess fats from the body. 

Enhanced Reproductive Health

According to the Centers for Disease Control and Prevention (CDC), sleep deprivation can affect the hormones related to fertility in both women and men. Your sleep is further accountable for triggering the regular release of hormones that affect women’s ovulation and sperm maturation in men.
Evidently, long-term sleep deprivation can cause trouble conceiving. 


Dr Kausthub Desikachar says though it will be challenging to adapt to this new habit, the gradual addition of hours you sleep will lead you to win this battle in no time. Let us all give our body the sleep it needs and the time it needs to heal our body and keep us healthy. “Early to bed and early to rise makes a man healthy, wealthy and wise.” Have a Good Night’s sleep every day.
