The neurobiology of crying in infants and adults is complex and poorly understood. As you might expect, direct physiologic studies of infants are lacking; however, some experiments have been performed in adults. Multiple investigators¹ have concluded that emotive crying is associated with increased sympathetic nervous system activity.
Heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs)
are chemicals formed when muscle meat, including beef, pork, fish, or
poultry, is cooked using high-temperature methods, such as pan frying
or grilling directly over an open flame
These chemicals are found to be mutagenic and may increase the risk of cancer.
Surprisingly when I was looking this up, I figured out it was true. Due to recent research, the below was realised.
When we’re hot, we naturally cool our bodies primarily by sweating, or more specifically by having the sweat evaporate from our skin (that’s important!). Our bodies sense changes in tissue temperature by a network of thermosensors located in ...

Elevated temperatures are thought to decrease sperm counts in males.
Elevated temperatures impair sperm production and function. Although
studies are limited and are inconclusive, frequent use of saunas or
hot tubs may temporarily impair your sperm ...
Surprisingly: yes, heating honey can be of a certain concern.
The article linked to above is based on ayurvedic principles which do not compare well in their reasoning with modern scientific thinking:
First, Ayurveda claims that heating honey to 104°F/ 40°C or above causes a negative chemical change that causes it to become bitter. This makes it undesirable ...
Hot fluids(including water) can:
Relieve Nasal Congestion
Soothe Uncomfortably inflamed membranes that line the nose and throat
By relieving symptoms you can make a person feel as if they are well or getting better. So yes I would say it helps. So just the hotness of the fluid can be a benefit.
From a study:
“The hot drink provided ...
Dry heat sterilization is fairly inefficient, time-wise, in general. According to Wikipedia, which cites the CDC for this:
The proper time and temperature for dry heat sterilization is 160 °C (320 °F) for 2 hours or 170 °C (340 °F) for 1 hour or in the case of High Velocity Hot Air sterilisers 190°C (375°F) for 6 to 12 minutes.
But this is for all mirco-...
What matters is the so-called wet-bulb temperature :
The wet-bulb temperature is the temperature read by a thermometer covered in water-soaked cloth (wet-bulb thermometer) over which air is passed.
If the wet-bulb temperature exceeds 35 C, then that's going to be fatal on the long run, as the human body can then no longer dump all the heat it produces ...
Getting dizzy and collapse in the sauna or during running is not enough to say that this is from heat exhaustion. Such symptoms can also occur in vasovagal syncope due to heat and the associated stress resulting in a drop in the blood pressure.
Symptoms of vasovagal syncope and heat exhaustion can be very similar (dizziness, pale and clammy skin), but in ...
There is no evidence that cold drinks during or after meals adversely affects health - in fact - the opposite may be true.
In studies of people with pure liquid meals, the temperature of the liquid had essentially no effect on the time it took for the stomach to empty itself (i.e. digest the food). Additionally, it is worth noting that a liquid as it ...
