  1. I sure know I haven’t been getting anywhere near enough sleep of late, and I’m certainly feeling the effects of it. Even my eyes feel dry.

    It’s interesting to read how the body is hard at work while we sleep, as we tend to think everything shuts down the moment we close our eyes, but after reading here what actually goes on, nothing could be further from the truth.

    I also now understand how a lack of sleep can lead to weight gain. This never made sense to me before, but now it does.

  2. I totally agree with you 100%. Sleep is a must for good health. Our bodies have to have it to recharge and repair itself. I was totally alarmed when I was reading the other day and saw how most teenagers do not get enough sleep. Outside of babies they need more sleep than anyone! Great information Doc!

    1. Another issue people frequently believe they can miss a few hours sleep and catch up another night. Not true! Adequate is important every night and can not be reclaimed.

  3. I can relate to the benefits of a healthy sleep pattern and how important it is. Many people do not know that it can effect you metabolism along with many other things. This article was very informative. I use to struggle getting more than 5 hours a sleep a night but fortunately that was in the past.

    1. Yes your metabolism is adversely impacted by lack of sleep.  Studies have shown an increase incidence in Type II Diabetes in people who do not get enough sleep.

  4. Some fascinating thoughts and facts on sleep. Enjoyed reading your article very much.

    So sleep is when the magic happens. So many, many benefits. Growth memory etc. Fascinating stuff. Thank you very much.

    I think that one of the most important reasons for a broken sleep is eating late in the evening. The digestive process uses so much energy and how can our bodies relax when so much energy is flowing through our bodies ?

  5. Honestly, in this busy schedule, I barely find time to sleep. However, I do sleep for 5-6 hours and do not feel tired even after I finish sleeping for that long.
    Another common question is that does waking up early mean a lot to the health, I’m basically more productive during the night time and sometimes sleep at 5 am in the morning is that going to affect my health?
