Not infrequently when swelter at night, AC (Air Conditioner) or air conditioning in the bedroom turned on all night. The risk is not just catch a cold, according to research that also can lead to high blood pressure.

Keigo Saeki, MD, a scientist from Nara Medical University in Japan proves thing it in a new research. According to him, the cold temperature during sleep can affect blood vessel constriction and ultimately increase blood pressure.

In his research, Dr. Saeki reveals that if someone is sleeping with a room temperature of 57 degrees Fahrenheit or about 14 deracat Celsius, blood pressure tends to rise 6-8 percent the next day. In comparation, sleep in the room with temperature 76 degrees Fahrenheit or 24 degrees Celsius.

Dr. Saeki explains blood pressure naturally will increase when a person wakes up in the morning. Well, when someone is sleeping in the room in cold temperatures throughout the night, the increase it will become higher because the blood vessels experience constricting or narrowing.

"These conditions increase blood pressure at least 2 hours, and during it happens tension that serious on the heart," explains Dr. Saeki.

Even if his relationship with cardiac considered excessive, sleeping in a room that is too cold can actually be directly perceived its effects on the body. Usually, people who sleep in a cold room will wake up with body feels stiff because catch a cold.

If have heating, advisable precisely the room temperature be raised in order to more warm during sleep. No need to be turned on all night because wasteful of energy and would also not be healthier if it gets too hot, enough be increased only the temperature 1.5 hours before sleep and then turned off.

Or can also with another way of using a thick blanket. No need to be too thick also, because it was freezing or swelter are equally uncomfortable to sleep and in the end both could reduce the quality of sleep.
