Too little sleep can affect more than your energy levels. Both sleep duration and sleep quality may influence blood pressure and, in turn, the risk of cardiovascular problems, reports Prevention.
Blood pressure normally drops at night
For most people, blood pressure is lowest during the night and in the early morning. It then rises again during the day and typically peaks around midday or in the afternoon.
Sleep gives your blood vessels a chance to rest
While you sleep, your blood vessels have time to recover. Too little sleep can disrupt this natural restorative process.
One bad night can raise blood pressure
Even a single night of insufficient sleep can cause a temporary rise in blood pressure. The greatest concern, however, is when sleep deprivation becomes a regular pattern.

Fewer than six hours may be problematic
Studies have found an association between getting less than six hours of uninterrupted sleep and having high blood pressure.
Research points in the same direction
A review of 14 studies found that people who were sleep deprived experienced an increase in blood pressure afterward.
Less than seven hours increases the likelihood
A study published in the journal Hypertension found that people who slept for fewer than seven hours were 20 to 30 percent more likely to have high blood pressure.
Sleep quality also matters
The number of hours is not the only factor. Interrupted or restless sleep may also affect blood pressure.

Sleep apnea may play a role
According to the experts, sleep disorders such as sleep apnea may also contribute to high blood pressure.
Tiredness can affect the body indirectly
When people are tired, they may be more likely to eat more and develop poorer insulin sensitivity. Both are risk factors for high blood pressure.
Long-term high blood pressure can have serious consequences
Persistently high blood pressure increases the risk of heart attack and stroke. It can also damage the brain, kidneys and eyes.
Better sleep requires a consistent routine
Some of the negative effects may gradually improve when people regularly get at least seven hours of sleep. One good night of sleep, however, is not enough.

Other habits can support healthy blood pressure
The American Heart Association also recommends a balanced diet, limiting alcohol, regular exercise, stress management, maintaining a healthy weight, quitting smoking, taking medication correctly and working with a healthcare professional.
