However, the duration of your nap can determine whether you see positive or negative effects. Naps exceeding half an hour during the day could possibly lead to serious health conditions like cardiovascular disease, diabetes and metabolic syndrome. A study published in April found that naps lasting more than 60 minutes a day increased the risk of type 2 diabetes by 50 percent.
In addition to that, it found longer naps also increased risk of metabolic syndrome by 50 percent. In another study, naps lasting longer than an hour significantly increased the risk of cardiovascular disease—by 82 percent. Yes, frequently taking long naps could lower your life expectancy. Naps lasting longer than one hour have been linked to an increased risk of death from all causes.
A recent study found that the risk of all-cause mortality increased by 27 percent for long naps, while short daytime naps increased risk by seven percent. This site complies with the HONcode standard for trustworthy health information: verify here. This content does not have an English version.

The amount of time you spend napping really depends on the time you have available, how you want the nap to work for you, and your plans for the coming night.
Generally speaking, the longer a nap is, the longer you will feel rejuvenated after waking. Long naps of one to two hours during the afternoon will mean you are less sleepy and require less sleep that night. This could mean it will take longer than usual to fall asleep.
If you are planning to stay up later than usual, or if taking a little longer to fall asleep at bedtime is not bothersome, time your nap for about 1. This is the length of a normal sleep cycle. You will experience deep sleep for about an hour or so followed by light sleep for the last half an hour. Adequate sleep, around seven to nine hours in a hour cycle for most adults, is essential for optimum immune and brain function, to reduce your risk of car accidents, and decrease your risk of a range of chronic health problems.
Excessive daytime tiredness could be a clue to an underlying sleep or health problem : when in doubt check with your doctor. There are two consequences of having a nap.
First, it decreases the drive for sleep. This is good if you need to be awake after the nap, but can be problematic if the nap is too near your usual bed time. Second, if the nap is too long you can feel that horrible groggy feeling after waking up, called sleep inertia. If you need to be performing well immediately after the nap, keep it to a brief 30 minutes. Even a very short nap can keep you performing at your best, but if you are not especially tired or noticing cognitive impairment, napping is not essential in daily adult life.
Many individuals are sleep deprived, and a chronic reduction in sleep is related to reductions in physical and mental well-being. Sleep deprivation has been linked to cardiovascular disease, diabetes, obesity, memory loss, and anxiety and depression.
