Why is sleep so crucial for immunity
“You know the key to your immune system? And that key is sleep. Poor sleep weakens your immunity. When your sleep is disturbed, your body becomes more susceptible to fatigue, diabetes, autoimmune disorders, and many other illnesses,” Dr Krishna explains.
He adds, “Our body has the natural ability to fight diseases, but we don’t use it properly. This is because during sleep time, we are often glued to our phones. To reduce inflammation in our body, we need proper sleep.”
How to strengthen your immunity through sleep
Dr Krishna further explains the science behind it, “When we stay awake, the hormone melatonin, which is the sleep hormone, doesn’t get a chance to work. And this is why our immune system cannot recharge. To strengthen our immunity, we need to let our system recharge, and proper sleep is essential for that.”
He advises prioritising consistent, uninterrupted sleep to allow the body to heal, recharge, and maintain a strong defence against illnesses.
