You might never realise it, but lack of sleep for even a single day can impact your health in a negative. March 15 is observed as World Sleep Day, and the very observation of a day dedicated to importance of sleep signifies how important it is for your overall health. When you don't sleep sufficiently, you are likely to feel grumpy, moody, tired and stressed. It can affect your work performance, making it difficult for you to focus. What's more is that lack of sleep can put at risk of diseases like heart disease, diabetes, obesity and even depression.
Ideally, an 8-hour sleep is required to function properly. However, this may be different for everyone, depending on the level of physical activity. In case you wake up tired every day and feel the need of taking a nap the entire day, it is a sign that you are not getting sleep.
