If you usually get up to use the bathroom at night, you may not be as rested as you would prefer when the alarm went off. And if you're puzzled by the cause – maybe you've already reduced your fluid intake at night to solve the problem – a new study could provide the answer. Scientists in Japan have come to the conclusion that calls in the bathroom at night may be a sign of hypertension.
Dr. Satoshi Konno of the Department of Hypertension at Tohoku Rosai Hospital in Sendai, Japan, said in a press release: "Our study shows that if you need to urinate at night – called nocturia – you may be under pressure and / or blood pressure increased fluid has too much fluid in your body. " Dr. Konno added, "If you continue to have nocturia, ask your doctor to check your blood pressure and salt intake."
To test the relationship between nocturia and hypertension (or hypertension), the researchers conducted a study with 3,749 people. They compared their blood pressure measurements with the results of a questionnaire filled out by participants and assessed their bathing habits at night. Under nocturia, researchers understand one or more trips a night to the bathroom.
"We found that getting up at night to urinate was 40% more likely to be hypertensive." Konno. "And the more visits to the bathroom, the greater the risk of hypertension."
However, the study did not establish a "causal relationship between nocturia and hypertension"; In addition, results outside Japan could not be applicable. Dr. Konno added, "The relationship can be influenced by many factors, including lifestyle, salt consumption, ethnicity and genetic background."
Also, high blood pressure is not the only health problem associated with needing to urinate at night, and you do not have to rush to find out you have high blood pressure because you do not have nocturia. According to the Cleveland Clinic, other problems such as sleep disorders – especially obstructive sleep apnea – may be responsible, or may be due to the medications or supplements you take (too much vitamin D can cause frequent urination). The Mayo Clinic notes that urinary tract infections (urinary tract infections, urinary tract infections) can also increase the need for toilet visits.
Alternatively – and this could shock you – your nighttime bath may simply be the result of too much drinking at bedtime. Alcohol, coffee, and other caffeinated beverages are particularly prone to cause nocturia, says the Cleveland Clinic.
The National Sleep Foundation recommends that you see a doctor if you wake up two or more times a night to use the bathroom as you are unlikely to find that you have enough rest. A record of how often you use the bathroom at night may be helpful, suggests the non-profit association. Your doctor may order a urine sample and perform a test on your bladder.
On the other hand, if you have the nightly habit of kneading an ice cold drink at 10 o'clock, you should just give up.
