Urinary frequency at young age

Hi..I am 24 years old and have facing the problem of high urinary frequency for last 8-9 years.

I often have to make frequent trips to restroom and feel the need to empty the baldder after short durations (60-90 mins), though the quantity to pass is not always substantial.

Regular urine test was normal, only specific gravity of my urine was on higher side of scale.

In early morning hours, the need to empty bladder is very strong even though I am not done with my regular sleep.

During slight anxious times while awake till late night, the frequency is very high: alomost every 20-40 minutes.

Are there any natural remedies to curb this ? No infection was detected in general medical tests
