Firstly, sleep is related to both physical and mental health. Sleep plays a major role in wound healing, warding off infections, reducing stress levels, and protecting against chronic conditions. Sleep and the immune system have a bidirectional relationship. If a viral infection can affect sleep, at the same time consistent and good quality of sleep also strengthens the immune system.

Secondly, have you ever noticed if you are not feeling so well, lethargic, or suffering from a headache. Getting a nap always makes you feel better. The reason behind this is that good sleep reduces inflammation. The immune system is a complex network throughout the body that provides multiple lines of defense against illness. There are 2 types of immunity innate and adaptive.
When we are sleeping, our body goes into resting and healing mode. Many studies show that sleep gives a boost to both innate and adaptive immunity. When someone is ill or injured and has good sleep, this revs up the inflammatory response which may help in quick recovery.
Sleep also has a major role in strengthening immune memory. It improves the ability of the immune system to recognize and react to dangerous antigens.
Lack of sleep is also the root cause of multiple long–term health problems. That is why we should always keep in mind that to achieve an optimal level of wellness. Do not forget to sleep.
Melatonin is also known as the sleep hormone is the first thing that comes to mind when we are suffering from poor sleep, jet lag symptoms, or even delayed sleep phase syndrome (tendency to go to bed late and wake up late). Melatonin is a natural hormone that our body can produce too. It is produced by the pineal gland. Darkness prompts the pineal gland to start producing melatonin while light causes that production to stop. To improve melatonin naturally, we can increase our morning daylight exposure, spend some relaxing time in the evening as well as maximize darkness at night.
Other than that, to improve the quality and duration of sleep or if you are suffering from mild insomnia. You can always take vitamins and supplements both in IV Drips and bioidentical compounded hormones.
