Climate and your bedroom in Puerto Rico
Puerto Rico is tropical and warm all year, with a hurricane season from June to November. Humid nights ask for a fan and air conditioning set to a comfortable level, and storm warnings can disturb sleep, so prepare in advance and keep a charged phone and a simple emergency kit.
A cool, dark and quiet room helps most people. A common guide is 15 to 19 degrees Celsius, although many homes cannot reach that, so use airflow, light bedding and shade. See how temperature affects sleep.
Daily life, work and sleep in Puerto Rico
Puerto Rico does not observe daylight saving time, so in summer it is on the same time as the US East Coast and in winter one hour ahead. Holiday seasons such as Christmas bring long parties into the night, so keep the wake time steady.
The island has a lively late evening culture, so keep the caffeine to the early part of the day.

Frequently asked questions
What time zone is Puerto Rico in?
Puerto Rico uses UTC minus 4. It does not use daylight saving time.
How do I beat jet lag?
Shift your schedule toward the new time zone for a few days before you leave if you can, choose flight sleep to match night at the destination, get daylight at the right time after landing and keep the first nights steady. Many travelers adjust about one hour of time difference per day.
How many hours do teenagers and children need?
CDC guidance lists 8 to 10 hours for ages 13 to 18, 9 to 12 hours for ages 6 to 12, 10 to 13 hours for ages 3 to 5 including naps, and 11 to 14 hours for ages 1 to 2 including naps.
Does a consistent sleep schedule really matter?
Yes. A regular sleep and wake time supports your body clock, which can make it easier to fall asleep and wake up. Large gaps between weekday and weekend times can leave you feeling jet lagged on Monday.
Are 90 minute sleep cycles accurate for everyone?
Ninety minutes is an average. Research shows cycle length differs between people, and cycle length can vary within the same night. That is why bedtime calculators give estimates. They are still useful because they turn a vague goal into a realistic schedule you can test.
Is jet lag worse flying east or west?
Eastward travel is usually harder because you must fall asleep earlier than your body clock wants. Westward travel asks you to stay up later, which is generally easier.
How many hours of sleep does an adult really need?
The American Academy of Sleep Medicine and Sleep Research Society recommend at least 7 hours a night for adults. The National Sleep Foundation suggests 7 to 9 hours for most adults and 7 to 8 hours for people 65 and older. Some people need more, and you can judge your own need by how you feel on days you are not sleep deprived.
How do I move my bedtime earlier?
Shift it by 15 to 30 minutes every two or three days while keeping the wake time fixed, get bright light after waking and dim lights for an hour before bed.
