00:00 How hot is the temperature now?
00:04 Your country tried to cook an egg in the middle of the hot day.
00:11 What is the result?
00:12 Let's find out in the story of Rod Lagusan.
00:15 The country is experiencing a continuous hot weather.
00:20 According to the forecast,
00:21 normally when it's dry season, the temperature is high because of the hot weather.
00:27 This is usually in the months of March, April, and May
00:30 where it's easy to get rain.
00:32 In question, can the weather be hotter in the coming weeks?
00:37 It's possible because climatologically speaking,
00:40 our record of highest temperature
00:42 is in the months of April and May in different parts of our country.
00:46 So if we're experiencing 34 to 35 degrees in Metro Manila,
00:51 we're not ruling out the possibility that we might reach 36 or 37 degrees
00:55 in the coming days of April
00:57 or in the coming months of May.
00:59 In this context,
01:00 the heat index is higher than the temperature.
01:05 This refers to the actual heat that our body is feeling.
01:09 Perez explained that aside from the high temperature,
01:12 the moisture content or relative humidity of the air around us is also high.
01:16 Humidity refers to water vapor in the air.
01:20 In dry season, even if the temperature is high,
01:23 the relative humidity of the air is low.
01:25 So if we sweat, the sweat immediately mixes with the air
01:29 and our body temperature quickly cools down.
01:31 But in dry season,
01:33 what will happen is that when we're hot and sweaty,
01:38 our sweat doesn't absorb the air immediately
01:40 because the relative humidity is high.
01:43 If that happens, the sweat doesn't immediately go away from our body.
01:47 The cooling process internally in our body slows down
01:49 so we feel hotter.
01:53 So if the temperature and relative humidity are high,
01:57 the heat index is also expected to be high.
02:00 The heat index is based on the classification.
02:03 If it's a caution, it's between 27 and 32 degrees Celsius.
02:07 Fatigue or fatigue is possible here
02:09 after a long day of sunbathing
02:11 that can lead to heat cramps.
02:13 Extreme caution if the heat index is between 33 and 41 degrees Celsius.
02:18 Heat cramps and heat exhaustion are possible here.
02:21 The danger is between 42 and 51 degrees Celsius.
02:26 And the extreme danger is between 52 degrees Celsius or more.
02:29 When it comes to this, a heat stroke is possible.
02:33 According to the forecast, the effect of the heat index
02:35 also depends on each person,
02:37 just like the senior citizens when the weather is like this.
02:41 We're here at the Pagasa compound,
02:43 which is near Science Garden,
02:45 where the temperature is measured in the area of Quezon City.
02:49 According to the forecast, as of 3 p.m. today,
02:52 the temperature here is 35.4 degrees Celsius.
02:56 And when it comes to the forecasted heat index,
02:58 here in Quezon City, it's 41 degrees Celsius.
03:01 And to test if the heat index that we're experiencing here
03:05 is possible to cook eggs.
03:08 We have two eggs here.
03:10 One is made of metal,
03:12 while the other is ceramic.
03:14 We'll try to break it to find out
03:17 if these eggs will be cooked.
03:19 In this experiment,
03:21 the eggs were not laid in the sun.
03:23 After being laid, the eggs were immediately placed here.
03:27 After one hour of laying eggs in the sun,
03:30 we can see that both eggs were laid
03:33 and both eggs are like cooked.
03:35 This is the same as the one we can see here
03:37 that is made of metal.
03:39 It's the same as the one we can see here
03:40 in the eggs that are made of ceramic.
03:43 According to the forecast, in this experiment,
03:45 it's based on the duration of exposure or sun exposure.
03:49 It also includes the material I used
03:51 where the eggs were placed or cooked.
03:53 Like metal that heats up faster than ceramic.
03:56 The metallic object absorbs heat faster.
03:59 So, it's possible that the prolonged exposure
04:01 of the metallic object that the eggs are placed in,
04:05 will result in it being hotter than the actual heat that hits it.
04:09 It's like it's collecting heat energy.
04:11 It's only proven that continuous exposure or sun exposure is harmful.
04:16 So, remember to have hope.
04:17 If you can't avoid being exposed to the sun,
04:19 bring an umbrella, drink water,
04:21 wear light-colored clothes,
04:23 and avoid sun exposure.
